Car will never see the drag just the occasional roll. Don't see the need to spend 1k plus on a clutch. Looking for stock pedal effort or easier. Spec 3 looks like an option for 400. Thoughts on a flywheel as well?
I’ve been running the centerforce dual friction in my fox for a while and has been smooth as silk for 5k’ish miles. I just pulled the trans a couple days ago to start my th400 swap.A number of us have the Spec 3+. We all seem to agree that the pedal effort is reduced, it holds the power well, and doesn't cost a fortune. Only real downside is that it chatters in first from a stop. Hill starts sometimes make me feel like a rookie all over again. I opted for the matching flywheel from Spec with the billet insert. I often wonder if the clutch would chatter less had I kept the heavier stock flywheel.
Is a Centerforce dual friction still a thing? I put one in my old GT and it worked great. Granted I was at 1/3 the power, but it drove smooth as silk.
The Promotion clutch in my car also had a blue Spec pressure plate. I didn’t put many miles on that car, but the clutch had great manners.I’ve had two Promotion clutches in my car. I liked the old basic one when I had an eaton, and now I have the one rated for 700 ft pounds with the blue spec pressure plate and it’s been good so far. I have an aluminum flywheel and it’s not as easy to get going from a stop as a steel one would.
I’m not 100% sure, but believe Promotion blueprints them or modifies them in some way. I’m not positive, but it could be similar to referring to ID as a middleman for Bosch?Years ago a buddy bought a clutch from Promotion. He sent me pictures of the spots where they removed the Spec stickers. Might be worth eliminating the middle man.
I want to say the rating was right around 500. But I know from first hand experience it can handle at least that while launching on drag slicks.^ I had a Centerforce dual friction in a supercharged 2V long ago, and agree it was great. But, what is the HP and torque rating?
Possibly. I do remember he didn't have good luck with it. But generally he was the guy that if it could go wrong to someone it would happen to him.I’m not 100% sure, but believe Promotion blueprints them or modifies them in some way.
