For those of you making "big" power like this, what clutch have you found to work best? I was thinking a sprung 6-puck, with the ACT X-treme PP.

 

i have a new Ogura racing clutch thats suppose to handle 400 fine. i also have a new mazdaspeed 3puck sprung.. not sure if it can hold 400 :/

 

I've been told my SPEC Racing Clutch should be fine for my ~400rwhp.

 

os giken 700u twinplate here

 

ACT street strip XT disc clutch and Pressure plate that I have is rated at 460ft-lbs of torque and its not as harsh as a 6-puck

you figure 400 HP at the wheels, you will probably make about 325-350 ft-lbs of torque... clutches are rated by torque holding capacity, not by HP... our cars torque numbers are always about 20+% lower than the HP number

 

I've been using a RPS 6 puck clutch. I personally stay FAR away from ACT, as their 6 and 3 puck clutches are a solid hub, wich is very bad on a transmission, aka, shattered gears. The RPS clutch I am using is the ceramic on one side and kevlar on the other, fully sprung hub, so its not as harsh, and lasts longer than full ceramic. Using the heay duty pressure plate, my clutch holds up to 500ft-lbs of torque, yet has smooth engagement. I'd check them out!!

 

is that plausable that that would happen? holy hell... i've been using ACT clutches on all my cars... thats scary...

 

IM pretty sure ACT does make a sprung 6-puck. If youll notice in my 1st post, I did say I wanted a sprung clutch disk, but I was planning on a ACT pressure plate.

 

the new mazdaspeed sprung 3puck i have is for sale... *shameless plug :P*
