i dont think its so much the pressure you run but the heat the s/c is subject to. my sc12 ran 15psi all day every day for years wiht no troubles at all, but maybe im just lucky.

Yeah, my understanding is that the toyota superchargers have teflon rotor tips to stop them wearing out, but if you spin them too fast, then you can melt the tips. I could be wrong though...

Sounds spot on, if they are coated rotors. The new Mini Cooper-S is known to have rotor-tip problems when people overdrive their S/C and run flat-out for long periods. The factory approved "John Cooper Works" kit includes a changeover S/C with slightly different rotors, coated in a more heat-tolerant polymer. -Thus solving the problem while running more boost.

Why does it have to be a positive-displacement pump? Centrifugal S/C's reputedly throw-out WAY more top-end H.P.

Have you got something against top-end H.P, Rozz? Mad

Just messin: Boost = good Very Happy
