Default Why does clutch feel different at WOT?

During normal driving, the clutch feels great. It engages/disengages at normal pedal depth.....BUT at WOT, it grabs literally right off the floor. What causes this? The fluid is relatively new, and the reservoir is full. ABout 30 seconds after slowing down, the clutch feels great again......

I am having the same problem. After replacing the slave cylinder it helped for a day at the track slipping the clutch to some 1.7 60's, but my car has began doing this again so I am leaning towards the master cyl.

I've always suspected heat was the reason. As power levels go up, so do the frictional forces and the amount of heat around the clutch and exhaust areas. Try some insulation on your lines and see if that helps.

There are numerous factors that contribute to this problem.
The drill mod, wrapping the line, flushing the fluid all help.
I have found that an adjustable master halps alot as well. (See stickies at the top of this forum)

Another thing that happens at high RPM the centrifical force on the pressure plate diaphram spring it great. It will cause it to hang or delay some & aggrivate the problem. This can also cause pedal feel complaints at high rpm.
