most a month before it will no longer grip at all. That's the problem I was having with my previous car (2000 Civic Si) while running a 65 shot of nitrous. The clutch would slip and eventually grab, but if I would have kept punishing it it would have failed completely. I bought my Z w/ the RPS 6-puck Max clutch already installed, so I unfortunatley can't relate any first-hand Z experience w/ the stock clutch.
