Title: Race clutch advice Post by: Fastorq on September 13, 2009, 20:10:30 pm My 1425lb buggy has a Kennedy StI with a CB 4 puck plate.
(http://im1.shutterfly.com/media/47b9d732b3127ccef84edde455c000000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) After 14 passes the 4 puck has glazed and the clutch started to slip around the 10th or 11th pass. What should I do ... I'm told a Black diamond plate with the StI would be good but fiercer and will hit harder maybe cause gearbox breakage. or Stay with the 4 puck - have it bead blasted and move up to a StII Kennedy. The glazing on the 4 puck showed full contact on the pressure plate side but only half contact on the flywheel side so is this an indication of not enough pressure plate pressure. I really dont want to have to pull the engine and replace pressure plate and friction plate every 10 passes but equally want to keep the box in one piece. Regds DavidR Buggy is a 2165cc draw thru 260hp turbo running consistant low 11s and once a 10.8 - only ever done 14 passes.

but I would guess that your Stage one needs to be set up with the depth of the flywheel correct. First put a straight edge accross the face and note the conical distortion. Once you machine it flat and the flywheel too, you may still need to shim out the pressure plate from the flywheel, so that the diafragm does not go over centre. I have to do that on every one I do, even though the FW is within VW specified depth.

It has to be checked with the flywheel and pressure plate to b used?
