First off let me say this is an awesome site!! Lots of info..

My question is I have a PA supercomp c4 and Im having trouble keeping high gear clutchs in it. We have had alto blues and reds and all have only lasted around 100 miles or so. The guy that rebuilds them for me is a backyard type guy and I dont think he does all the stuff I have read about on this forum.
My car is making over 800rwhp so I was wanting to know if it was the setup or am I at the limit of the clutches in the c4. It has 6 high clutches. Thanks alot.
