Is anyone doing this sucessfully? My old Cartek clutch failed miserably, even without N20, so it's time for a new clutch. I'm looking at the SPEC Stage 3 and Stage 3i. I know the 3i is rated to handle more hp, but I'm afraid of a few things with it. The first thing is that they simply haven't been out very long, so to me, they're not yet proven. Also I have heard that sintered iron disks wear very rapidly. Most people seem happy with their regular Stage 3s, but I'm not sure how many of them are being used on Heads and Cam plus Nitrous cars. If you are sucessfully running this combo, please let me know the following things:

1. What is your launch RPM?
2. What is your average 60' times?
3. What tire are you running?
4. How long have you been sucessfully doing this?
5. Any other pertinent info?

Thanks alot. I've done plenty of searches but haven't found this specific info.

I'd like to know as well. I'm looking at adding a small (100hp) dry shot to mine.

I dont run @ the track much, but I run around on 315 Nittos which dead hook on the street. Clutch grabs like hell..

Ran @ the track once, leaving off the limiter it didn't blink an eye

That sounds promising. Anyone else have any input?

I don't have heads, but I've got a cam car pushing down 415ish to the rear wheels with a 175 shot of dope on it. Here's the list.

1. 6600 rpm launch
2. high 1.5x average 60's...
3. running a 28x10.5 ET Drag
4. I've made at least 50 passes at the track like that, and probably that many again on just motor.
5. My entire clutch system consists of a stock '01 Master and Slave cylinder that has never been disconnected from one another. (ie. no drill mod, factory GM fluid, etc) I'm running a SPEC Stage 3 Carbon disc. Have about 35,000 miles on it (car has 48,000)

Wow, great info! Thanks. Sounds like yours takes plenty of abuse with no problem. I'll bet it has alot to do with proper break-in.

my break-in only consisted of not taking it to the track for the first 400 miles. For the first 100 miles or so I took it "semi-easy" without doing a BUNCH of hard driving. Then for the next 300 miles I drove the car just like I do every other day, rather aggressively. At the end of the 400 miles I went out to a back road and did 5-6 5,000 rpm clutch dumps on street tires, which got rid of 99% of the chatter the clutch had.

I have a spec stage III ceramic in my 99 T/A and with N2O on the street it hooks on drag radials. I usually just walk the car out of the hole and then mat it.I have only about 2k miles on this clutch so far and I love it. It never gives up.
