a good clutch will have an amount of slip during engagement. this allows for great driveabilty and clutch modulation for traction.


what i meant by slip was during full power, at torque peak (whenever that maybe in the powerband) does the engine rpm rise without the car moving any faster.

my clutch masters stage 3 started slipping during a 10psi 1/4 mile pass. with only 250hp it should not have been doing so. shift from 3rd to 4th the rpms shoulda been around 5,000 rpm. on the last couple of runs, engine was ending up at around 6,000rpm and my MPH kept going down run after run.

turns out the flywheel was not machined correctly and would not allow the correct pressure the clutch needed. This explained the weak/mushy pedal pressure. and after 3 years of use with little wear on the disc, no room for small amounts of wear since there wasnt enough pressure to allow the disc to wear and still clamp correctly.

i got a new clutch with a correctly machined flywheel and oh my god. i never thought a stock organic disc could hold like this. its all in the material, pressure plate, and how much pressure is put on the disc during operation. i've got a dual diaphram clutch which is like having the pressure of 2 plates in one. one is stacked on top of the other. pedal pressure is higher than stock, but FEELS GREAT. i can feel through the pedal just what the clutch is doing. i could NEVER do that with the pucked clutches i've ever used.
