Whos running over 700whp on an 8.75?

Have you looked into a clutch tamer?..
You do actually want just a tick of slippage.. you can adjust that slippage in the driver's compartment on the fly according to conditions of the day...

I sure havent! But I'm going to start with a clutch thats at least rated for the HP. When I pulled the clutch out there were hot spots everywhere.
