Clutch package for 500 whp
Trending Topics
Ditto. good clutch. My previous clutch was a jesus cross unsprung, and exedy HD PP in 8.5". it was a light switch amd couldn't hold 3rd gear 100%. Running 9" act 6 puck sprung and their 2nd heaviest pressure plate now, it just grips and is much easier to modulate. Phyisically heavy though - even with the lightest swiss cheese steel flywheel, it weighs in pretty heavy.
I don't make 500whp but I do make 400wtq, which is more then cars I've tuned at 500whp put down and is what your clutch is actually fighting against. Exedy hyper single wouldn't hold it, ACT HD pressure plate and ACT 6 puck sprung disk, holds the power all day long. That and as you've seen from the other forum members; it's proven.
It really comes down to that or cough up the crazy money for a Exedy twin disk. The ACT clutch is not as bad as some are making it out to be, but if you're going for big boy numbers you are going to have to make sacrifices. Big boy clutch is one of them.

Over 6000 miles on the clutch and its still holding, I think the torque rating is 575 ft/lbs, I'm under that a little for what its worth.
Can't beat it for the price especially compared to a triple plate.
I have 3 herniated discs and I'm using this same clutch, ACT sprung Six puck. Its holding even at 810RWHP (Dynojet) / 703RWHP (dual eddy current mustang dyno, Steve Kans Dyno). I honestly don't notice too much of a difference from stock other then it engages right away. I also have to mention since my 13B is a full bridge, I idle at 1500-1600 RPMS so it might be a little different than if you had a stock idle.

Do any of you guys flat shift? And if so, how does your clutch handle it? I have found that if you're flat shifting, the torque rating of the clutch needs to be substantially greater than the mfg's published static ratings (and your engine's output) to hold, otherwise it will slip if the tires bite in the higher gears.
Spec 3?
Its GARBAGE, don't waste your money on it!The spec 3 setup for the FC3s started slipping at 350 RWHP on my fc. Don't have any input on the spec 4, since I went with the ACT organic disc and the second heaviest plate, so far so good at 350rwp

As far as flat shift is concerned, we haven't tried it yet but will soon, setting up the Motec so we can do that.

504whp/417ftlbs
ACT sprung 6puck and Heavy Duty pressure plate. Rated at 512 ftlbs it holds my power all day. Driveability is great. Grabby but nothing extreme. Love it.
