well I race a 94 6spd with exhaust,dp,intake and he was at 16psi and beat it. We race from a 40-mph roll and I got 1/2 or 3/4 car length once the race ended. My mods at the was only exhaust,bcc,ebc, and I was ast 13psi.

Hope that helps

Depends on the driver. Auto has the advantage of building boost off the line, and also maintaining that boost if you pull the trac fuse. Manual has the advantage of keeping revs higher. But how many manual drivers can keep up with an auto? Not many.

If you're building a full out drag only setup then auto's are great. However I think there's plenty of 6 speeds out there that have proven themselves. Especially when you consider some of the features the AEM EMS gives you with the 2 step and anti-lag. This gives you the ability to build some major boost of the line, and maintain rpms. So if you got the slicks then you should be able to get the sixty foots. As for loosing boost between shifts.......do some full throttle shifting. Besides the autos aren't nearly as fun to DRIVE on the streets IMHO and around corners for a street car. As Ryan Woon said it after is 9.65 pass on his 6 speed with a blown IC pipe, nothing beats slamming the gears as you're going down the track.

If you are going to drag race a lot and still want a pretty streetable car then auto is definitely the way to go. If you want a car to just cruise on the weekends then definitely 6speed. I have an auto but IMO a 6speed would be more fun for just cruising around town. Although I love my auto in rush hour :cool:

Stock for stock, no. Built slushbox vs. a manual comes down to the driver. Go search up the several videos of Titan's car nuking and paving several built autos because the driver could, y'know, drive.

Auto = Porn.

Manual = Sex.

:D

95% of the drivers with a 6sp would be toasted by a built auto. They is no way in hell any driver can shift faster than my auto.

The 6sp has more potential, but has a much higher driver talent requirement.

Unless your name is Ryan Woon :D

How do you figure the 6speeds have more potential though? Do you mean because there is less drivetrain loss?

Yeah, more power to the ground means the potential to go faster.

I dont know about you guys, but there have been way too many auto vs. manual threads lately. Did the search button stop working? :D

Get a converter worth buying and lock it up (Not single clutch)... then tell me about drivetrain loss. Efficient converters that are locked up are just as good.

I don't think the converter is the only problem when trying to lock it up. I'm no expert, but I think there is a line pressure problem or a problem with how much fluid can be held in the tranny that prevents safe lock-up. Search around or ask SP, they can probably give you the info. You remember what happened when everyone got the 3 disks that were specifically designed for lock up right... wasn't pretty.

I haven't seen any dynos where a locked up converter on an auto can get as much hp as an equally modded 6speed......I guess there are a lot of variables like the condition of the turbos and what not, but it isn't something I have seen.......:)

Auto transmissions are my thing. Yes, I realize line pressure has lots to do with lockup, that is why we raise the pressure. Tranny holds 9-10 quarts ... plenty of fluid... I do remember when PI had their completely inferior triple clutch available. #1 they used rounded lockup tabs... think about that... rounded? They just sheer off in a heavy load. #2 they didn't use billet aluminum. #3 Their clutches were built to slip more to decrease the load hit. More slippage = more heat. No thanks.

Contact VNTPerformance... he will show you numbers of an auto that match or beat a same setup 6 speed. Just takes the right tuner, tranny, and converter.

Yes I do talk to VNT, he doesn't make incredible amounts of power he is just a demon at the drag strip :)

Well I'm no tranny expert so I can't really tell you the full details of the problem that SP reported. If you have found a converter that can safely be locked on the stock Toyota tranny I would love to hear about it. I'm sure there would be a lot of us who would get rid of our single disks. I know I definitly would be interested.

And yes, a locked converter can make close to as much power as a 6 speed but not quite. I love my auto but we must admit that the 6 speeds are capable of putting down more rwhp than us. Val makes great numbers but put a 6 speed in there and they will be better. He just has goods mods and a great tuner.

all you have said is not correct. i own an auto. im running a BCC, RMM DP, K&N drop in, apexi N1 cat back, bleeder-T mod and a HKS TT type 1. thats all. and from a 40 roll i held off a 6spd until we shut dowm at 130. an auto will have you off the line, will have you at low speeds. the only thing it cant do is high speed highway runs,
