I can tell you the fastest stick car I've ever had any real experience with didn't slip the clutch. NHRA SE record holder, heavy car, making under 500hp. 9" slicks. leaf springs, traction bars, and very expensive for the times double adjustable shocks. Ram 3 finger PP and I think sintered iron disc. (based on memory...) 7200 on the 2step - he would slip his foot off the pedal.
