Good 10 second clutch.

Dark_5.0 · 04-12-2007, 12:19 AM

My 1990 coupe is a track only car and "should" run mid 11's on motor and high tens on a little nitrous. I launch off the limiter and drive it like I stole it.

Anyone have any suggestions? I have done some research and am leaning towards the Spec stage 3 clutch.

If you have the money then go for the Spec 3, but my Centerforce DF has made a 10 sec pass on the button with no problems, I launch at 6000 and also have an aluminum flywheel. Good luck.

Yeah I am also going with an aluminum flywheel. I even bought ARP flywheel and presure plate bolts.

The Spec stage 3 seems like the way to go.

Thanks,

A SPEC stage 3 is NOT necessary to run 10's. I have an AFM stage 1 in mine, which looks very similar to the disc used in the SPEC I kit. The pressure plate is different though. I've heard numerous people say the SPEC PPs are too heavy and can hurt the transmission pretty quick.
FYI, I ran my car probably 60 passes last year, all with at least 6000 launch RPM and mid 1.4 60fts. I pulled the clutch out over the winter expecting to change it, but it looked brand new so I slapped it back in and have put another 10-15 on it this year so far.

I'd suggest looking into AFM, Pro-motion, centerforce, or mcleod, but stay away from the SPEC III

Thats good to know. My philosophy has always been to go easy on the cam and overkill the clutch but I dont want a clutch that un-necessarily tears up parts.

I will look into the AFM clutch.

Thanks,

FWIW I got a spec stage one in my car and we had to grind quite a bit in the bellhousing (stock) to get the pressure plate to clear, the motor wouldn't spin by hand and after a little hassle and looking we took off the B.H. and saw the blue paint (could have been a lot worse) had to grind and fit grind and fit.

You never ran one, no one on here said any bad about it. The
stage 3 + came highly recomended for my new application.

no, but I'm heavily involved with other high horsepower stick-cars. When a transmission company tells you not to run a certain clutch because it will likely break the trans, I tend to listen to them.
