I picked up a Fidanza 4.3 which is a sprung 6 puck ceramic disk. Heard some good reviews & know a few guys that are marking around the 500awhp mark with them & their holding up great (yes I know clutches should be rated for torque no hp).

Personally I think its a combination of both the friction material & clamping area that determines the actual holding power of the clutch.

As mentioned above the CFDF probably won't be a good choice in this case. It won't take the abuse of those kinds of power levels in an awd car. Now if the OP was fwd, it would be a great choice.

Thank you Greg, that was heroic!


I don't think this one is so great because the bottom of the fridge and water bed are not clutch friction material, and they are probably not on a metal floor either

Who the frack would want to slide a water bed around? And fridges have rollers.

I personally think it's because in every puck setup, there's a little Chuck Norris in the friction material, and he round-house kicks the pressure plate into turning with the disc.

Look, I'm not making this stuff up, right out of text books. The problem with your waterbed analogy is that water beds way around 10x what a fridge does, so ofcourse it is harder to move.

As Tashko said, there will be a small change in friction coefficent due to pressure. For a stiff material like is used in ceramic based clutches it is almost 0 change, for a soft material like tires it is more pronounced due to mechanical interlocking(but still would not make the difference between 300 and 500ft-lbs). Either way if you don't accept it I'm taking my ball and going home:)

I agree that it's probably a combination of things, and I also incline towards Tim's way of thinking.

Heh, you guys sound like my wife when I'm trying to explain something to her...

"You see, hon. Life is like a box of chocolates...You never,"
"What are you talking about chocolates for? I wasn't talking about chocolates!"
"I'm trying to make an analogy so that you can understand it. In a box of chocolates the choices seem to always change..."
"You keep going on about chocolates! You're making me hungry! Do you have any chocolates? I'd kill for one right now."
*Sigh*
