I have a new fx500 clutch from clutch master and it has worked great for dyno and street. i went to the track and it started slipping so i took it out to inspect the problem. the clutch looks new but it slips. i did not see any oil on it or hot spots. but here is the kicker made 3 passes in the 1/8th ran 7.5 98mph, then it slipped 2 passes then made 3 passes again it did not slip at all. i know its slipping when it slips because the rpm goes up but the mph stays the same in my datalog and the et is way off.

 

when this happens it is just slipping because its so hot from back to back passes, it just needs more time to cool between being beat on is all.

 

you think preloading to long could cause this.

 

What kind of power?

 

Yes premiering puts alot of heat into the clutch disc and alot of back to back runs does too. What kin of power are you making ? What flywheel?

 

it makes 375hp and 330ft tq @ 16 psi its a f22a. its in a eg civic and the build is in my sig.

 

stock or aftermarket flywheel ? Did you have the flywheel resurfaced ?

 

its a evo h2b kit and it was new
