Thanks for taking the time to weigh everything Tony. I'm going to use those weights over on my registry if you don't mind. :)

Steve,

No problem on the weights...feel free to use them. The flywheel itself weighs in at 23lbs alone on my scale and on the same scale my stock flywheel weighed in at 32-33lbs, so the flywheel itself is about 10-11lbs lighter. I am not sure what good it would do to know that instead of what the entire complete setup weighs, but I am sure we can think of some reason to know the weight of just the flywheel.:)

Here is the breakdown:

Pressure plate: 16.5lbs
Discs: 5.5lbs
Flywheel: 23lbs

Looks good Tony! I think you'll be happy with the setup.

Get that thing to the track so we can see how those MT's really hook up. You better run some 9's on that turbo, because you know I'm going to once the trannies fixed.... :)

I am anxious myself to see how everything goes with my car and yours. When is the tranny due back?

Oh yea...and no slipping the Tilton to run that 9 with the turbo I am running...that is considered cheating.:)

I have around 170 miles on this clutch now. If I listen very closely I can hear a very very light noise at my 750rpm idle...of course if I would idle it up the noise would go away, but you can't hardly hear it anyway. You would have to be listening for it to hear it, so I don't mind it and I do really like my 750rpm idle. It is definately not nearly as noisy as when I used to have a RPS stage 3 with a lightened flywheel!!!

I just drove around today and tuned my decel fuel with the lightweight flywheel...it seemed to throw that off slightly. Everything works great with that now. Most people probably wouldn't have noticed anything when driving it, but I like to have the driveability the best I can possibly get and I guess I like to tinker a little too.:)

Also, a very important point about this clutch...I can take off at an idle and not have to worry about killing it or anything like that. I think that is definately an important factor to consider for the driveability of a clutch.

I really don't mind revving a car up some to take off, but it is a bonus if you don't have to I guess.

EXACTLY!!
Also, if for any reason someone else needs to drive or park your car they can without restarting it fifteen times. My clutch when cold is a guaranteed theft deterent system. :)

Just a little update for everyone.

I have the clutch broke in now...engagement is still very smooth. I tried some launches with it on the 255x50x16" ET Street Radials and it hooked very well...I only had the tires at 25lbs. It was hooking so well that I had to flip the screen out on my Pioneer AVIC N1 and see what kind of G's it was doing...turned out to be a consistent 1.2 G's everytime.

I know that quite a while ago when I brake boosted the car in 2nd gear and hit it...of course it came on hard...the car pulled almost 1G...probably .9. Here recently when I went from a dead stop with the ET Street Radials where I could slip the clutch I pulled 1.2G's consistently. I tried it 4 times with the meter on.:)

Anyway, so far I am very happy with how this clutch/tires is/are allowing me to take off on the street...I have never taken off harder with the ET Streets with the Feramic disc on the street. The ET Street Radials were at 25lbs of pressure too! I will try and drop them down and see if I can take off a little higher...I was free revving the car (no 2-step) between 4900-5400rpm and slipping the clutch some too.

Anyone have any suggestions on the best tire pressure for the ET Street Radials on the street?

Thanks for the update. This setup is killing me. People either hate it or love it and its making it hard for me to make a decision on my next clutch. I had a carbon/carbon on my old 300ZX and I loved it. The pedal feel was a bit hard but the car was VERY driveable and it never rattled. All the 300zx guys rave about it. Wish I could say the same about the Supra community :) Its either the RPS carbon/carbon, HPF Feramic or the ATS Triple Carbon

It took me quite a while to decide myself, but so far I am happy with the choice I made. If you try the ATS out be sure to let us know how it holds up. How much is that one going for anyway? How big are the discs...7.25" or so?

I had a VERY old version (like the first I think) on my Stealth. The frame on one of the discs broke at 7300 RPM a few months ago.



Supposidly they remedied that situation with the normal clutches. They've been replacing them thru attrition. Mine actually lasted longer than most. When I got it fixed up (for a good deal I might add) I went with the pro-disc. Supposidly the discs are made out of a more durable metal that is stiffer so that the discs don't flex as much.



Here you can see how they beefed up the edge of the disc to contain the pads at high revs:

Tony, Glad you like the clutch...now we need to convince all the other Supras around here that they need to ditch that HKS triple in favor of the RPS.
