View Full Version : Weight Reduction: How MUCH of a Difference?

Hey All,

I've been cruising the forums a lot lately checking out what people have done with weight reduction and some of the ideas are fairly obvious (eg, back seats that are 65 lbs) but, anyone who has gone all out ripping out all unneccessary stuff, how much of a difference has it made?

I realize that most are going to say that you have to choose what you want; you have to balance accordingly on your tastes.

I'm just wondering what some of you have done and what it feels like when driven?

The spare tire and the jack are a big difference, if you get rid of the back seats and get racing front seats. It'll make a huge difference.

Well said... That's probably the most common route... Nobody needs a spare tire when u can get on a cell phone eh? 8)

It makes a big difference. Car just gets up to speed quicker, requires less braking and can handle better. This sounds obvious, but it feels like you're driving a lighter car, even with just a couple hundred pounds off. Everything is more responsive. Driving a 2400lb car is quite fun, too bad the Supra will never get that light and stay street legal.

Every 100lbs you take off the car equals about a tenth lost in the 1/4 mile.

Well I have heard that one of the socal guys took the front bumper suport out...that is a COUPLE HUNDRED pounds by itself. I just have to say, that is not going to help you any if you get hit head on, But if your going 100 + MPH it really doesn't matter if you hit someone with the suport or not......your going to die.

Ahhhh, Ok... When I read about how u should get rid of your air conditioner and stuff like that it's one of those that make you go "hmmmmmmm... :dj:

I wish the Supra wasn't so heavy, but it's so great in all of the other areas, there's no use in nitpicking... ;)

Take a look at my Naked Supra thread. I actually took it for a drive like that. Man it flies. I was going sideways through the first 3 gears, it feels like a different car. The turbo and bov sure sound sweet too with no hood on. I figure the car weighs about 1000 pounds lighter now. and it sits 1" higher now.

there is this old guy i know here in co. he told me how he lightened some of his stuff by going and changing alot of bolts in the car that are too long with shorter aluminum ones. he weighed all the bolts he took out and it came out to be about 125 lbs. but im too lazy to do that.

Whew: I've got a targa and they're heavier!! Wonder what I weigh the way she sits!!! My brother in law has 90 LX Stang and he weighs in at 3170 with him in the car! I know I'm heavier, but he can't hang with me at all!!! He hates that!!!

put a lot of money on your car and you will got a lihgter car.
example:
change all for exotics materials like carbono titanium and aluminium from N.A.S.A.
front hood
seats
piston block
conectic rods and valves in titanium ( all it´s good to lower the weight)
alllllllll

CF fenders and door skins would lighten the car quite a bit, remove any accessories + all wiring ie AC, TEMS, ABS, etc

Doors would be good, but the fenders are light already.

See, the SEARCH buttom works!

My talon is like 3100 lbs after some weight reduction. I used to think that was a Sled, till i found out the curb weight on the Supra is like 3400 lbs.. CRIPES!

Goal: Curb weight = 3100 lbs w/o driver

Here are my ideas:

Pull all Jute padding from under carpet
Scrape off all Tar-mat sound deadner
Cut out any Rubber/vinyl under carpet
Remove Spare tire and jack
Remove 'wood' panel in hatch area and any compartments
Remove Side impact beams in doors (are there any?)
Remove Front Bumper (or does the bumper cover attach to it?)
Remove Rear bumper (or does the bumper cover attach to it?)
Remove ABS unit
Replace Factory speakers w/ lighter more efficient parts
Any bracing under the headliner or side panels to remove?
Remove Vapor canister (can i run the vent line to the air filter housing?)
Replace Front power seats (even though they are SOO cool)
Replace stock seat belts w/ 5pt harness?
Replace SRS steeringwheel w/ Sparco/momo?
Replace Shift lever?
Is there some emissions/AIR pump to remove also?

Any heat sheilds, splash panels, or the like to remove?
Are the calipers big and heavy like MKIV? (can you switch to Celica brakes?)
Switch to MKIV rims?
One peice driveshaft (how much and where do i get one?)


I wanna try to do all the free mods before i start buying upgraded/lightweight parts.

thanks

really, thats insane. So your car is pretty bare inside?

I kind of wanted to keep some sort of semblance of a "stock" appearance.

I know at the DSM shootout, if you have your interior completely removed, like how yours sounds, they put you in some kind of Outlaw class. But if you keep the panels and some kind of carpet, you get to be in some Street class, even if you took alot of shit out anyways.

Have you weighed your car after all that?

where do some of you get these outragous numbers:rolleyes: sound deadner 80 lbs, i think not i've posted this at least 10 times, ALL the sound deadner weighes 45lbs, the door weighes 45lbs with nothing in it or bolted to it, the door skin is only about 5lbs, the reinforcement is whats heavy, how do i know? heres a sneak peak:D sneak peak (http://groups.msn.com/projectsupra/shoebox.msnw?action=ShowPhoto&PhotoID=74) and come on the fold down part of the back seat can't be more than 20lbs with the bottom being maybe 5lbs, lets see what else.... bumper support, closer to 50 not anywhere near 100lbs, fenders are already light, if your worried about the jack being heavy get a rx-7 aluminum jack, yeah the A/C system is pretty meaty, TEMS weighes next to nothing, aannnddd ooh yeah the bolts, my car is stripped as far as it can go right now and i've got a bucket of bolts, maybe 40lbs at the most:rolleyes: ok i'm done now;)

02-04-2003, 11:22 AM
Projsupra, thast interesting, i didnt see any of your posts.

anyways, it depends on how thick the sound deadner is. I know the front seats have got to be pretty heafty, especially the driver seat w/ all the power adjustments...got to be insane.

anyways, my point is...a curb weight of 3450 is RIDICULOUS!! the freakin MKIV is only like 3260, and everyone complains that the MKIV is a Turd.

However, that idea w/ the RX7 jack is good. The jack in my RX7 is only like 3 or 4 lbs...

Id at least like to get my car down to about 3200, i think thats a realistic figure. my main concern is keeping carpet, interior panels and back seat. its nice actually having a back seat people can use, unlike our Talon and my RX7...the back seats in those things have been appropriatly named "AssTrays". its crazy, it really is.

The interior door panels arent that heavy maybe 5lbs each. Where can i get a driver window w/ a crank mechanism? or did most of the supras have pwr windows? I will keep the pass door power, cuz i HATE leaning over and crankin the window down...it looks so stupid when someone does that. You know, Semi trucks have crank windows on the driver side, but pneumatic window on the pass side.

Do the JZA70 doors have side impact beams?? if not, then i wont feel so bad about takin mine out.

As far as the front and rear impact bars...i would feel wary of takin the rear out since i cant control other drivers and they might hit me.. But the front i wont feel so bad, since im in control of what I hit...i already learned the hard way to keep a BIG distance..so big of a gap that people automatically think im letting them into my lane.

projectsupra
02-04-2003, 11:29 AM
all the posts are pretty old, and nobody uses the search anymore it seams:( yeah drivers seat is close to 65lbs and the pass is only 30something lbs:p there is three types of sound deadner in the car, a sheet type, a ply type with insulation inbetween the sheets, and a sheet with mesh thats tacked to the back wheel wells, i chisled it all out, put it in a bucket and weighed it, 45lbs
edit: all supras came with power windows, i suppose you could make rx-7 manuals work but why lose the option to save 20lbs;) all doors have the save reinforcement, here (http://groups.msn.com/projectsupra/shoebox.msnw?action=ShowPhoto&PhotoID=71) is a pic

I've got a crap load of stuff outta the car right now. I'm gonna go buy a scale to weigh it all soon. I'll index everything as I do it. This is just such a pointless thread without anyone doing that. So many people just guestimate how much stuff weighs and you'd be surprized how far off you are. I'll post my results in a about a week.

Just for the record though, a turbo MKIV is 3500lbs

Exterior Dimensions Base Sport Roof Turbo Turbo Sport Roof


Curb Weight - Automatic (lb.) 3255 3315 3425 3485


Curb Weight - Manual (lb.) 3215 3275 3415 3475

Driver seat---72 lb's
pass seat-----45lb's
spare---------50
sound deadening tar---45
a/c-----------------------20-25
charcoal canister -----5
Cruise controll---------5
rear seats-------------???30 most

i think i got everything cosmetic here.Get ready ............................................. TOTAL WEIGHT ISSSSSSSSSS........................................................................................................................................... ...................................................................................................................................................... ................................................................................................................DING DING DING 277 POUNDS!!!!!!!!
Ok put back the racing seats-------------30lb's
i put in a set of 240 sx seats that weigh ----30lbs each so i totaly saved 217 lb's

not bad huh?This thread is so dramatic,lol.I love talking about weight savings,because its mostly free,and no need for a turbo

277lbs? I dunno I went from 3620 to 3050. I also removed cruise, AC, windsheild/headlight squirters, radio, and have a fiberglass hood skin...

Oh and I wouldn't remove those door braces unless you have a full cage with a "Nascar bar". Those reinforcements might add enough strength to save your ass if some moron ever blows a red light and T-bones you...

i posted this on STLSR board but will post again here as it fits well.and my car is running tip top now.



well for all of you who dont know. Me and Str8jakett have quite a bit in common. we are both named Ryan, both drive Mk3 supra's, both are N/A, both 5spds and both are burgandy. well we were driving out to hooters last night and i was following him and well he has his int. gutted to hell. where as i have a full int. but i have more mods than him.

well we are on 270 going to go pick up a friend. we i pull along side and at 60 we punch it well i pull ahead prolly about 5-6ft before his car starts to gain well by the time we stoppedi was at his back bumper. surprised the hell out of both of us. we contributed this to a few factors. like my tires are 225/60 series and his are 225/50. and that my car is running very lean.

well we go and pick up our friend who makes up the differance for the gutted int. well on our way down to so. co. we line up again this time we punch off at 70. well i instantly take off and pull away easily. by the time i hit 110 i was a good 2-3 cars ahead.

who knew that little weight could make such a big differance. although i have a theory why my car is running so bad( i raced an 02 turbo passat from a roll and barely won) is that my O2 sensor is not in direct flow of exhaust so has a flase reading and also i found a leaking pipe at my TB. making my car run very lean. it was weird i tried 4 times to top out and the car wouldnt go past 110mph. in 4th or 5th gear. when before id hit 140 with reletively no problem. so as of now we will call this a draw. and when he gets his hacked up exhaust fixed and i get mine fixed well have another go.

02-05-2003, 10:53 AM
thts probably what it is...Bad intake leak will fudge everything up.

Yea, i LOVE FREE MODS!!!

Alot of people gripe about how AWD DSM's weigh...and we did All the free mods that can be done and the weight reduction in the back half, and the car is about 2950 w/o the driver.. 3120 with the driver...i couldnt Beleive that shizzle..

Jeff (MA71) how did YOU get your car down to ~3000??? is it pretty barren inside your car or what?

I think i would only remove the Side impact beams if i had at least a 6 pt cage...even then that might be a little risque...or is that risky?

I also wanted to try fabbing up front and rear impact bars out of Aluminum thats similar in thickness to the steel thats currently on the car.

My girlfriend has to drive the Talon all the time, and its pretty loud inside...you can hear the tread noise from the tires very well, plus the gear noise from the rear end...plus the air rushing under the car since we took bolts out and there are now open bolt holes that lead under the car...Its just a bunch of "WHHHSSSHHHHHHHHHHHHHHH" when you putt down the road. Its worth it though... sometimes. She says that she doesnt want me gutting the supra cuz its so plush compared to her car... she sometimes wishes she hadnt gutted the talon..oh well.

my car weighs 3300 even with me in it. that was after a shit load of weight reduction.
i took out everything with the ac,sound deddining,carpet,spare,back interior,back seats,charcoal canister, power steering, and other small stuff. i still had my jack in, i dont know why. but i remember when i first got the car it weighed like 3540. thats a pretty big difference. i never got to see the difference at the track though. i would of proably seen high 14s all motor which sucks,lol. but once the spray went on i never really ran it on motor.

02-05-2003, 05:54 PM
LOL, what about driver weight reductions? LOL
Heck, I probably weigh more than two or 3 of you combined, so the only mods that will make sense to me are power adders, not cutting up the carpet, removing the seats, and making your nice GT car loud and uninsulated. (Try that one in the North, you'd be a frozen critter if you tried to drive very far with no interior at 20 below zero.)
I agree with the alloy front and rear rebar mods, but don't ever take out the side door impact bars.
I adjust claims, and if you want to die, go ahead and remove them. It's your choice. I think someone mentioned T-bones, but there was a comment about ok on the front, because I can controll who I hit? Hello, ever seen a head on collision on a two lane road? They are very common, and with no front bar, you are taking your chances. I'd rather be hit from the back with no rear bar than in a frontal impact. The rear structure of the car will take up quite a bit before it "hits" you. The front is not so kind. Nice little things like the engine and transmission, not to mention the tires and suspension all come back into the front seats. The tires are really good at being pushed back into your feet, and folding the bottem of the A post and floor up around your ankles, then you get to have them amputated. If you live that is. I've seen side impacts on trucks and vans before they were required to have the bars, and the passengers were mangled. (Many of them are fatalities, or they lose limbs or are vegtables for the rest of time.
So, have fun, take out some excess weight if you want a louder car, but don't mess with your basic safety systems, that includes the seats. If you replace them, use grade 8 or better bolts to secure the new ones, don't rely on cheap slider brackets to hold your seat belt anchors, and if you do attach to the floor, put fender washers on both sides of the bolt to keep it from pulling through on impact. (adjusted a claim on a honda with carbon fiber Sparco race seats. The owner had bolted them to the floor, but did not use any washers. I asked him about it later when they removed the wire from his jaw and face, and he said he did not want to add any more weight. On impact, he and his seat came out of the floor (bolts just pulled right through, and were still attached to the seat.) and into the steering wheel and dash. He is lucky to be alive, and lucky he did not modify the steering wheel as it crushed and deformed just like they are designed to, and that saved his chest and torso from intrusion. Grade 8 bolts, and fender washers on both sides of the part your mounting to is a safe way to do it. Had this guy done that, he was in a 5 point harness, and excellent seat. He might have just unbuckled the belts after the loss, and walked away.

i took out everythin in my trunk, the spare, and all the tools, the board, foam, jack, little compartment thingies, the big metal piece. but i didnt take the trunk carpeting off because its attatched to the seat. i want to go lighter, but i still want everything to look normal. what else can i take out that is decently heavy? how bad does it look when you take the back seats out??

MA71, YIKES.... thats what our Talon looks like...we at least in the back. The front half of the car still has some semblance of original...except we took the leather seats out in favor of cloth, unadjastable seats from base model Talon. Looks like you still have a little Tar matting on your inner fender well...:)

I dont know if im THAT committed to losing the weight. I guess, ill take out what im comfortable with (everything EXCEPT AC, PS, PW, Impact bars and top layer of carpet) and see where that gets me. I DO live in florida, and i know im gonna regret takin the AC out, and it IS a heavy car w/ big front tires, so ill regret takin the PS out. Cant find any crank-window conversions so ill be stuck w/ Power. I dont want to die or be crippled in an accident, so ill leave my safety equipment in. And i want it to "LOOK" decent, so ill leave the top layer of carpet behind.

How do i get NHSTA approval on home-made bumpers? I really want to make Alloy front and rear impact bars, but i want them to be certified also so that i know they are good and wont crinkle like a beer can in an accident.

Adjuster, any thoughts?

Thanks

i got my car down to a wopping 3150 and found out that in the quarter you can loose traction big time, but on the freeway its a blast. rainy days watch out. i dunno about removing the abs though, it has saved me a few times, it all depends on where you take the weight, most of the weight is taken from the rear which explains traction, now if you can take it from the front, thats a different story, i think some torch cutting might come in hand, but then again i love the feel of steel around me

Word up.

It sounds like your car is unbalanced now, and the rear is too light.

Id rather have a well balanced car then an all out, gutted GT car. whtever, i take from the front, i wanna take out of the rear. and vice versa.

I did some reduction my RX7, and the front was only 680 lbs of the 2720 race weight...thats some shitty distribution... that means the curb weight of my FULL INTERIOR RX7 was 2500 lbs!!!!

ok, i started my car on a Diet.

I want it to look normal when im done, as in, still interior panels and carpet. But i did strip all the padding off the carpet, got rid of that wood panel, and the brackets under it.

Whats up w/ the Spare?! its bigger than my RX7 wheels!!! freakin 16" spare?! a 205-55-16 tire?! cripes...thats a FULL SIZE SPARE!

I took out the rear most speakers too, the 6CD changer, and the 8" bass tube, still got a 2 channel amp and rats nest of wires back there though.

Took the rear seats out, found marbles and 2 dead cockroaches under there. I pulled the jute padding out from there also. the seats probably DO weigh about 30 lbs. They are going back in when im done, so are the interior panels next to the seats. I think the cargo area can stay stripped, except for the carpet, i think im puttn that back in to look nice. except, its lining the floor, and the tire will sit on top of it.

Water leaks? I have standing water in the spare tire well, and there was moisture under the rear seat cuz the bracing was rusty and the jute pad was musty and wet, and also in the grooves right at the bottom of the reinforcments where the access to the side corner markers are. Why the hell is it leaking in there, i dont know where its comin from...

Most importantly, WHY SO MUCH GODDAM SOUND DEADNER?!?!?! this is the thickest ive seen on ANY car. and whats w/ the wire reinforcment on the sound deader on the inner fender well? and why the hell is it SPOT WELDED on?! Is there one good reason why its 3/8" thick?!

What is THE best and easiest way to remove this shizzle? I gotta get rid of this junk ASAP!!

thanks!

02-06-2003, 06:27 PM
i dunno why you act so supprised to find all this out:rolleyes: you know the car weighs a good 3500lbs, much more than a rx-7 or DSM, so even once you strip it theres only so much your going to be able to loose, short of tube framing the car with a kevlar body:p i love having a full size spare, newer cars now are coming out with it now so i get to say i'm the origional, my car had that in 87, and this car is a luxury/GT sports car, 8 way power seats, airbag lumbar and side supports, auto climate control, and a VERY smooth and quite highway ride:) the sound deadner is thick for a reason, and the deadner with the mesh is to stop reverbirations in the rear panel when you hit bumps and crap hit your inner fender well. and most likely you've got water leaking in from your tail light seal, very common. geeze you sound like you're having withdrawls from the rx-7, i mean do you try to make your current girlfreind like one of your ex-girlfriends, when shes special in her own way ;)

02-07-2003, 09:36 AM
current girlfriend into my ex? well actually, now that you mention it...no, she was a neglective bitch who never made any effort to spend time w/ me or even contact me...

Anyways, i think i do wanna keep it looking normal like i said before. I just want to get the sound deadner off, I dont really care about how much noisier it will be. You dont know noise untill youve ridden in a Nonturbo RX7 w/ a full exhaust and a header...THATS noise. I dont get headaches from it, but it does drone on and on down the hiway. It is practically as loud as a SPort bike w/ a loud pipe...you really can hear it miles away when i get on it.... the flames are cool too. :)

"How do i get my Supra to sound like a rotary and shoot flames???" JK, crazy withdrawals...

I can understand water leaking in around the tail light gasket since they get old and brittle and fall apart. they did on my RX7. But, how did the water get all the way up under the rear seats?

Shawndude said he used a Water hose to pull up his sound deadner... i dont see how that works... that shit is on there GOOD. the only way i can think of, is using the spatula/putty knife/screwdriver w/ a hair dryer... Plus, i dont wanna fill my car with water. what do you think Project???

I wanna pull all the sound deadner off, im not worried about the thermal or audible consequences. so what the dilly?

nothing a sanding once over couldn't get rid of. Didn't realy leave anything behind once it was chipped up.

actually its easier if you have a 1" chisil, cause its wider and will take bigger peices off, its time consumong but it comes off pretty easy and do not use a heat gun cause it just melts everything and turnes into a sticky mess, and i have a n/a rx-7 with no exhaust at the moment and its pretty loud:) , sucks about the GF, i was just pointing out that this car will never be an rx-7 or DSM, its in a class of it's own

Ok, I think this discusion is focusing on wrong weight reduction...

Yes it is free and cheap but that doesnt save much pounds and just adds inconvinience.

The focus of weight reduction is getting and replacing parts that are heavy with parts that are redesigned to have the same structural streinght for just a fraction of the weight.

Weight reduction (if you want it to work) can be expensive


I got to go but I will list some of my ideas later tonight.

02-07-2003, 07:06 PM
i chipped up the sound deadener under the back seats...man its about 20 lbs. i cleaned it up a little, gave up trying to get the residue off since no one will see it anyhow, the seats are going back in. Ill start in on the trunk tommorow. I used a standard screwdriver..it probably took longer than it would have if i had a 1" chisel or something. But i was able to tap the screwdriver way under there and pull some big chunks. a Big fat chisle wouldnt be able to squeeze under there w/o cracking the tarmat. I did use the claw part of the hammer to reach under and pry it up a little at a time, i was able to get even bigger pieces off this way.

I took my spare tire out and saw water marks (like on a tanker or boat) inside the well that were only an Inch below the floor of the trunk. Must have been a big leak somewhere...there was still water at the bottom. It rained this afternoon and there was more water behind the inner fenderwells again.

I think im going to get a pair of sparco or corbeau seats and some 5 PT harnesses (installed properly w/ Grade 8 bolts and extra Fenderwashers :) ) that way i can dump the heavy ass seats and stock 3pt belts w/ retractors. Also, ill try to make some fiberglass trim panels that insert into the sail panels beside the rear seats. They are held in w/ 2 clips in the front and jsut slide out, and they have the 3 screws behind them that hold on the whole interior panel. You know, these are the panels that are parallelogram in shape /____/ should save me a few lbs.

Project, you wanna help me figure out some dimensions to build some Alloy/Aluminum plate front and rear impact bars?

2JZ_MA70
02-07-2003, 07:30 PM
Everything that has been sad is great idea and ppl need to decide what their level of comfort is.

The points that need to be addressed are:

Front and Rear cross member. Redesigned with lighter construction. Estimated saving of up to 200 lb. Posibly more if proper metals like Titanium and high carbon tool steel are used.

Dashboard and All Metal suports behind. (Est WS 100 lb). More if replaced with Carbon Fiber unit.

After properly designing a row cage one can replace many of the flor panels with aliminum that would be 1/3 of the weight of the steel used there. The wheel wells and suroundings can be cut out and removed completely or replaced with CF or Alum. (WS ~ 30-200 lb depending on how particular you want to get =) )

The rear window and quaterpanel windows can be replaced with Lexan. (not recomended if you want to keep your defroster.)
Misc brackets and bolts removed as last resourt. (WS ~50-70 lb)

After instalation of a row-cage much of the body can be guted because the main support is now provided by the row-cage. (WS ~50 lb)

Last resourt can be replacing the Power Steering with a manual unit. (Flaming River makes a unit for the mustangs that is suppoused to fit the Supra. ) (WS ~30-50 lb)

Remove the A/C system and lighten the heater box by removing all motors and directing air in certan position permanently. (maybe to the footwell and windows.) Or make a custom unit that would house only the blower motor, heater core and flex hose for ducts. Last resourt REMOVE the complete unit. (WS ~30-100 lb)

Rear seats removed and front replaced with light weight racing ones. (WS ~200 lb)

I will try and do much of that and I will let you know what I come up with... =)

I will probably have to buy another car after that but oh well in the name of the SUPRA it is worth it =) LOL

yeah I only went as far as I did because I can still use the MR2 when I need to. I used a chisel to get that tar out, its a pita, but worth it -- even if you just put the carpet back down to make it look stock.

Just be careful with it, I made the mistake of letting my domestic buddy help me and he put a nice hole in the floorboard chiseling too hard (he also likes to overtighten bolts "76ft-lbs?! no way man, those wheels are gonna come off! Better make it 100!")

the front and rear impact bars don't weight that much, and definetly not enough to justify replacing it with something i made vs. something that was designed by a team of engineers;) i trust my life to my roll cage but i wouldn't sell it to anyone else. and i can't believe you would think about tube framing you're car if your not going to go all out racing with it:rolleyes: power steering weighs nothing, the only thing you loose with going manual is the 10lb pump, reserviour, and some metal lines, it won't add up to 15lbs, i'm just doing it for road feel and cause thats that much less maintenance i have to deal with. another thing, i have every bolt that is put into the supra (except the subframe ones) in a bucket and it doesn't even weight 40lbs, the dash is relitivly heavy for a bunch of plastic and the tube brace behind it is too, but the won't add up to 70lbs. ok i'm done replying to this thread now, for some reason its getting my blood pressure up:rant:

2JZ_MA70
02-07-2003, 10:48 PM
Like I sad Im not sure on the numbers that is why I was guestimating.....

I will let you know what comes out of this.

The bigest weight saving will be in the 2 subframes and I plan to invest most of the money there.

The PS pump, lines, fluid, rack... it should add up to 40 lb.

The CF dash is a good idea but we will see what happens.
The dash I bet I can get 100 lb off. The dash its self is pretty hevy tehre is the harness that can be thined out the brace support and the center console all the misc stupid control modules...

LOL, project, is that the new concept called sarcasm??

I saw where this company made a hugh FMIC for the WRX and they supply a new Alloy front impact bar thats only 1" tall, but still conforms to the crash test rating. If they can make an aftermarket bumper to take up less space, be lighter, and still do the same job, so can we. I dont think there is a whole lot of "engineernig" going into bumpers. You make the metal thick enough to get the job done, weld it in the proper areas, drill the holes to mount it, and Viola, your done. It only takes a person w/ a 2 year degree to find out what thickness to make the metal and where to weld it for key strength and least labor. It takes someone w/ proper measuring devices and a drill to find out where to put the mounting holes and drill them. And as far as making sure it gets the job done, that takes a few prototypes and tests (trial and error) and recording the results.

As far as aluminum floor inserts...i dont want to risk having them SUCKED out while im racing, and then skidding along at the same speed of the car for 20 seconds whilst throwing straw colord sparks that only Ferrous metals can create. and then having it fly up when it passes under the car and create a UFO.

Another thing bothers me about Nay sayers. I had to deal w/ that on the RX7 club alot too. "oh, that only weighs 10 lbs, and This only weighs 7 lbs" well, you know what, if you take a bunch of things off that only weigh 10 and 7 lbs, it ALL ADDS UP!!!! its not like once you remove something, you have to start over again, and find some object that weighs X amount just so that it counts as a weigh reduction...

I converted my RX7 to manual (well, non power) rack and its a pain the ass. especially the amount of bump steer i get when drifting, id defnitly put my PS pump back on. and i wont bother taking it off my supra to find out if theres a difference.

i get to chip the crap out of my trunk tommorow.

Ill save the floors, firewall, and driveshaft tunnel for another day. and you can bet that crap WILL come out, i dont care if the floor gets hot.

EDIT: btw, can you weigh all the seatbelt equipment for either the front pass or driver seat? Do you have the 5 spoke MA71 rims to weigh also? Do you have the Stock DP w/ elbow and exhaust to weigh?

sarcasm, yeah thought i'd give it a try LOL:D i guess we could make some, i've got a MIG so we could use aluminum if you think it would work. but i just get tired of hearing "i think this weighs Xlbs" when it really weighs something totally different:p yeah you must have some tar thats not glued down good or something, i had to chip it all up and the biggest peice was only about an inch wide:( , of coarse my was sitting in a junk yard for 4 years. i can weigh the seatbelts but my cars an n/a so no turbo parts:( oh yeah but i totally know what you mean about the rx-7, mine is the lightest of the light and has the manual steering, i love the feel of it, much better than my bro's with power steering, but to each their own:p

I bet you those are 280 ZX T-tops.
Also bumpers 50 lbs would be good, if replaced by aluminum ones (not as effective).
If the bolts are 40 lbs it would be a nice upgrade. But beware, only you can replace non critical bolts with aluminium bolts, critical bolts with titanium. Aluminum bolts are lighter, but at the end it would be only 20 lbs.

Also I had a friend who used a very light carpet in all his stripped interrior, it looked nice.

PS the driveshaft should shave 20 lbs.

LOL, youre gonna break your damn bathroom scale...and then what are you gonna tell the Old lady?!

Thats cool though. I thought about removing the Rear most speaker sets, the ones w/ the Q-form boxes and the separate tweeter. those are kinda hefty. then i thought, they probably put out some good sound, maybe i can just get rid of the ones by the hatch cover anchor point...but thatll only add up to about 5 lbs total...and not worth the sacrifice in sound (i like my stereo loud and clear)

My tarmat must not be on there very good, cuz i can chisle up pieces about the size of a CD case...but then i will get pieces that are the size of a quarter also, so go figure. I just couldnt belive the one guy was gettin whole sheets, but i think its possible w/ high pressure water, it doesnt create pressure points that cause cracking like a chisle will.

Oh well, hows the Ttops going? what was the donor car?

actually the back seats weigh in at about 65lbs. they do have metal in them.

Im not quite sure what drug your on, but the leather rear seats that i have sitting in my room on the floor dont really weigh much. the bottom portion cant weigh more than 3lbs. and im guessing the top 2 weigh about 5lbs each. so thats an approx. 13lbs. how about you take your back seats out and weigh them cause i already have.

I thik I can get 100 off the dash. There is lots of junk back there that can be removed. If you add it up it would come close to that.

The car frame cant be 2500lb that is just outrageous and stuped... I gues i would have to get the plazma cutter and start going at ti and see how much I get off... =)

My suprize is that the heater box is only 5lb or less...

No, but don't forget about the inline six (read: long block and crankshaft) and transmission. Those two with fluids (plus radiator etc) probably come damn near 500lbs.

The problem I see with just cutting away metal is that the supra doesn't have a "frame" perse. And since I don't know which bits and peices are helping uni-body rigidity, I probably won't cut much metal out until the day comes when I can have the car tube-framed (or more likely tub-framed). And even then, I doubt I'll ever see the lite side of of 2500lbs...

And as I've said all along, there isn't really any one large item you can remove and magically get to RX7 weight. It's just a gradual removal of 10lbs here and there. There may have been 30 items all weighing in at 10lbs or less I removed. But when you've finished, you don't have much of a street car left.

Oh and one last remark. I've got a overflowing bucket of bolts and brackets that easily weighs 40lbs. But in it are things like the front tow bars used to hold the car down when it was shipped from japan (don't worry about winched on a flat-bed if you want to be towed, I was winched by my a-arms just fine), and the rear hanger for pulling the engine.

EDIT: that reminds me, the alternator/front engine hoist bracket weighs maybe 5 lbs (stupid cast-iron). Perhaps the MKIV style intake kits will replace that bracket with an aluminum one? Same goes for the exhaust manifold -- cast iron (and the turbo elbow too).

Damn...Ive decided that i want to keep some of the luxuries in the supra...but i dont need a 70 lb 20 way power adjustable seat...espcially since its ripped to hell and pieces of leathe rmissing. same for the passenger seat. Plus, after i spring for new chairs, ill throw in a set of harnesses so i can get rid of the stock hardware.

Where can i get a one piece driveshaft??? Should i have one custom made from an Ford Aerostar (1 piece aluminum 3" diameter) or any van? what kind of yoke connects to the tranny? is it a slip yoke or does it bolt into the tail shaft, and the driveshaft bolt up w/ a 4 bolt flange?

I chipped all the tar mat out of the trunk and under the rear seats... Ill save the front half of the car for another time. it was quite a chore, and i got a headache and nausiated from the reverb inside the car. really messed w/ my inner ear. anyhow, id like to get rid of frivalous stuff and stuff that is not absolutly necessary.

Im trying to focus on stuff that doesnt COST anything to do since im stone Broke and only plan on spending money if i HAVE to like...the HG which i need to do if i want to actually drive this car.

ok well.. to resolve the back seat thing. The whole assembly only weighs 28lbs. A little less than my guess. This is for leather seats too. The power driver's seat in leather weighs 65lbs. I measured it all tonight and I calibrated my scale before hand. I've began to put together a spreadsheet with all the weights of things that I've gathered. All that's on there I weighed tonight. I'll do more as time goes on.

Oh, and dont bother trying to chip off the tar mat thats spot welded to your inner wheel well...its a BITCH to get off. the top layer is ok, thatll come off if you rip the mesh off. but the layer on the Metal, is made out of some Porous tarmat, and it isnt solid enough to just pop off in big pieces...i was chipping and chiping and only getting CRUMBS...i got it all off, but theres a nice coating of tar still on the panel that i cant get off unless i used Xylene or brake cleaner to dissolve it.

No offense to you xp, I'm just using your statement as an example of the common misconception towards weight reduction.

First and foremost, weight reduction is the ONLY car modification which will make a car (any car) accelerate faster, brake in a shorter distance and improve handling as well. Nothing else you do will improve all 3 performance aspects at the same time. Plus it's free! If going in a strait line though is the only kind of performance you care about, then weight reduction is not for you. For autocrossing and road racing though, weight reduction is invaluable.

Of course, it does have its drawbacks... increased noise, potential ugliness, decreased comfort, etc. Just depends on what you're willing to sacrifice for performance.

flubyux2
02-13-2003, 01:54 PM
:stupid:

Very true.

But weight reduction, or at least relocation CAN benefit some Drag strip attendees. More weight transfer to the rear, unload the fronts, plant the rears harder, improve your launch characteristics.

If theres one thing i learned from Drag racing...its not how much weight you have, its where you put it. sometimes, too light is a bad thing...you simply cant plant the meats, and hook.

I know im not going to take a once-fabulous car, and ruin it by making it uncomfortable and ugly, this car was ahead of its time and can hold its own against most of the cars out there today. So, i just figured ill make do w/ what i got.

he is right, its the best bang for the buck mod that you can do...FREE is not someting to shake a stick at. :)

Just weighed my car today too.

It's an '87 Turbo Targa 5-speed with ABS and TEMS. Weighed it with about 3/8s a tank of gas, 245/50-16 tires, and my tool box in the back. (128pc. Craftsman socket set) Also any crap like my water jug in the back (I know Supras well enough) and anything that was in the console and whatnot. The car did NOT have the spare in it though, but it did have the jack. The car came to 3540 just like that. But that's what is weighs this week... he he he :D

Nope, wighed it today on a scale certified by NYS Dept Weights and Measures :) actually, it's the clutch that's the super heavy part. The whole clutch/flywheel assyembly is a hunk of lead weighing in at just over 40lbs. And that's all rotating mass too!

looks like you still need to chip it out from under the back seat and trunk in those pics. You got it off the rear fender wells right? quite a bit of work for about 5lbs eh?

I was afraid that all the sound deadner in the garbage bags was going to bust thru cuz it was too heavy for the bag itself...cripes man..

Still haven't weighed the car yet,.. but took it to the strip yesterday to see how it would act. Sloppy TEMS suspension set on normal, 30psi in the tires, and about half a tank of gas in it.

Previous best was 9.68 @ 78.5mph, with many consistant 9.75 runs... New best... :D

projectsupra
03-03-2003, 12:57 PM
lol nice run, i wanna know how much mine weighs casue yesterday i put my back tires on to move the car around and when i let the jack down the suspension didn't even compress, it looked like a monster truck, i had to jump in the hatch to make sure it wasn't stuck or something. it's still not light enough for me to pick it up but the back end won't compress the suspension at all :D

flubyux2
03-03-2003, 01:27 PM
thats what happend w/ my buddies 79 camaro. he removed quite a bit of weight from it, and his front end wont compress the springs at all...its crazy.

Are there any solutions to that besides Cutting the springs? i dont know if there are any "Light duty" springs for these cars... Maybe coil overs?

Supra Guy Scotty
03-03-2003, 03:08 PM
I know what you mean about the 4x4 look. I'm probably going to cut my springs. I like the sloppy suspension on it right now because of the weight transfer it gives when I launch in Normal mode on the TEMS. Heres a pic of my "lifted" Supra staging for that run! Hilarious!..lol

This is all on a stock engine, fuel, everything. Nothing but weight reduction, and 3" pipe straight out and HKS EZ boost controller. 11psi of boost. Spun bad the first 30 feet or so.

ok, added more stuff to the A70 weight index this morning. It's in excel format. You can get it here. -->A70 Weight index (http://24.161.30.77/suprapics/A70WeightIndex.xls) One big thing I weighed this time. All the sound dedning material in the whole car. One thing to note here. The material in the hatch area is much less dense than the material in the rest of the car. so those who have estimated the weight based on what they took out of the trunk. It's simply not a good comparison. So what does it all weight? 42lbs. A worth while endevour? I don't really think so. I plan on putting down new sound material in the car, so I didn't want to double up and have the extra weight, but my car is destined to be a show winner, so I'm forced to go the extra mile. One other thing the did weight a lot was the black sound material pad that is against the firewall. This thing weighs 8.5lbs. I though that was a little heavy for its size. I'm replacing this also. For the curious, here are some pics of a total empty supra:
http://24.161.30.77/suprapics/stripped.jpg

and here's what all that sound crap looks like crammed into two boxes and on the scale :D

i dunno if this got posted earlyer, but a good reduction is the stock seatbelts on the front. Just replace them with some 4 pt harness. they weigh next to nothing. also, maby the admin should sticky this so people dont yhave to search for this all the time.

anyways, i put weaponR 4pt harness in the driver and passenger and they weigh jack shizzle (ooo ghetto whitboy!)


p.s. that supra isnt totaly empty, i still see an e-brake:)

Rear seat belts only weight 5 lbs for the pair, including latches.... I can't find the front ones right now, but I can't imagine they are that much different, I don;t see how a 4pt could weight any more than a pound less, so you'd have better luck hitting the john for a #2 before you go racing... you'll probably save more weight :p .

Back seats dont weigh 65lbs.

with taking everything out i only lost about 200 lbs. i rember weighing the car with everything and bout 1/4 tank of gas was i believe 3400 and then with same quarter tank and everything out 3200 now what im question as i speak did i have a 1/4 tank or 1/2 tank of gas with everything out i dont remeber. but it gives u an idea. atleast

I tried to read all the posts and I don’t think I saw any weight estimates for the hood or the hatch. Has anyone weighed these? I would guess those two items would give you the greatest weight reduction out of any of the parts on or in the car.

This thread reminds me when me and my friend took his crashed 300zx NA and took basically everything off it. We took off all the fenders, the bumber, the hatch, everything inside and anything else that wasnt needed. All that was left was the hood, drivers seat, steering wheel and some other stuff so that it ran. It was crazy. It picked up so fast and u could loose traction in every gear. Even when u just mashed on the throttle while rolling the tires would start spinning. Best part about it was standing up in the back with the hatch off while he drove 60 down the road. If you want a rush thats a good way to get one :D

So as far as getting a head start on weight reduction, swapping a 7mgte into an 86.5 (no abs, no tems, hard top) is going to save me some time, as once its stock with the 7mgte, i should have an advantage over my buddies stock 88turbo(with abs, targa,tems)

Porsche has been doing weight reduction for decades. Obviously go with all the lightest materials, I wouldn't use any aluminum bolts that shouldn't be aluminum, but one of the most cost effective ways to reduce weight is to remove material. Porsches answer...drill the shit out of it! Suspension links, under the hatch, under ALL of the interior, all the beams under the hood, Under the door trims. Make it look like swiss cheese. Then if you are still froggy after drilling for about 2 weeks, dimple EVERYTHING!ALSO use a countersunk, or punch to lip every hole you made in panels thinner than .30. This will cold harden the galvanized steel you normalized then you drilled it.
Cold hardening will make it more resistant to corrosion and strengthen it. As an example I lost 3 lbs off my front bumper (support). Huh!? 3 lbs isn't a lot..? Well not to start...but let me whip a 3 pound weight at you, an' it's not so much to laugh at.
Your engine has to accelerate that 3 pounds, your brakes stop it. Think about it next time you and your kid are playing catch with a bowling ball.
Now do..the WHOLE car.

Hi mkiii guys :)

Weight reduction..how much of a difference?

Well, I personally noticed a HUGE difference on my MKIV after knocking off 400lbs :sadance:

A lot of people will argue the advantages, but I'll always be a fan of weight reduction. It improves my acceleration, braking, and turning. I can't think of too many mods that will improve all 3 of these aspects. Also, a lot of the weight reduction I did was free...can't beat that.

Hoping to hit 29xx lbs by the end of this year, and I'm confident I'll reach my goal. My current weight of 3080lbs is scale verified. Since then I've done some more things and my new weight will be in soon. Weight junkies unite.

where do you go to weigh your car?

Some gas stations have weigh scales for semis...that's where I weigh mine.

Accuracy is usually to the nearest 20lbs, and they always round up. Since mine came in at 3080lbs, its somewhere between 3060 and 3080.

Some junk yards have scales...So they can bill you on how much you dump. Might do it for free....might need you to float a few bucks.

Bye the way, Billy my hats off to ya. I was reading my MKIV brochure the other day, TOYOTA's talking about how they put the Supra on a diet with hollow carpet fibers and shit... Still weighs 3300 plus! Way to go gettin' it down. Have you drilled it?

There is a pic of my car on this forum at http://www.supraforums.com/forum/showthread.php?t=380580&page=4&pp=25
The weight is from a weigh scale at a garbage dump site with nobody in the car...as for the timeslips I haven't gone to a track with my car, the #s are from a gtech pro.

i striped down my 87 turbo to bare bones and mare minium to run no interior, no dash, no heat nothing in the hatch lexan windows
replaced the glass with lexan everywhere but the windshield and i only have one seat
me and my buddy can now lift onside of the car all by ourselves but it is a little uncomfotable to drive
love catwalking thru 3rd gear thou
lexan windows made the biggest difference almost to the point where i have lost too much weight in the rear end having all kinds of problems hooking; my talon had no such problem but the top end was lowering than the supra
dsm are crappy

Take a look at my Naked Supra thread. I actually took it for a drive like that. Man it flies. I was going sideways through the first 3 gears, it feels like a different car. The turbo and bov sure sound sweet too with no hood on. I figure the car weighs about 1000 pounds lighter now. and it sits 1" higher now.

got a link to this thread?

removing some of the heavier stuff from the front and back of the car ( like re-bar)
wont this throw off the wheight distribution of the car?
I see people stripping the shit out of the back of their cars, and leaving the front normal, I would think removing 100+lbs out of the rear would mess up the distribution

Every 100lbs you take off the car equals about a tenth lost in the 1/4 mile.

Its not a straight equation-relative to the size of the car.

For example-my Colt was 2200lbs. If I pulled another 100lbs out of it- I would probably see 2-3 tenths and another 3-4 mph traction limited. An 03 Cobra does not even flinch being 100 lbs lighter, since its so heavy already. Thats why people don't bother taking weight out of them.

You don't gain horsepower by removing weight.

Not worth the time? That's completely up to the person doing the work. It's absolutely 100% worth it to me, I'm STILL trying to find ways to make my car lighter.

I heard a couple times (i think it was in sport compact car too) that the best place for the battery is between the rear strut towers for balance. Go with a lightweight battery though if you want real weight reduction. Otherwise is will be just redistributing the same old weight plus a couple pounds with the new extra lenght wires.

removing weight does not equal horsepower, but you could say removing 7lbs gives you the same result as 1hp extra, but 7lbs is not 1 hp

weighed it at the state drag strip...i guess most drag cars will be somewhere between 800 and 1.5 tonne and id also guess that the weight of these 5 sec drag cars is pretty important..

but yeah - the scales might be reading within 5 kg off

nope all original fenders and bonnet and hatch - each with their fair share of bog in them

ive also painted the car inside and out extensively so that may add a few kg on its own also

yes im running a 5 gallon fuel cell
a small 7 kg

now b4 u see the pics - realise this is a track dedicated car that isnt completed yet!! it was slapped together from a rolling shell within a week inorder to make the last drag meet for the season. as such i havent painted and installed all the exterior trims and sideskirts etc. the car will remain stockish looking on the exterior. the wiring will be redone more professionally as 1 day to wire up whats required to make it drive in 1 day simplly isnt enough time (lights/indicators/power windows, battery and all other accessories down from scratch)

Questions:

-How is it doing at that angle, I was told they would fail if not mounted under the sump?
-Is it more efficient to run dual inline pumps as you are, or dual pumps on separate feeds to the fuel rail?

This is drastic but you can drill holes in the frame/chassis...strategically of course, can drop about 100-200lbs, but I wouldn't feel safe hitting a deer in that car...of road use only

not sure if someone had already mentioned that but I really didn't feel like reading page 3-8.

Just how much do you think an A70 chassis weighs if you think you can remove 200lbs with holes?
