Whoooops!
I have now spun 2 of these clutches, with a modified flywheel to give even more clamping force, and they couldn't hold 400+WHP.
It is the torque that you should be concerned with as anything over 400lbft (at the flywheel) and you are asking for trouble.
Watch this video and you'll see me roasting the clutch in 4th gear at the strip...
