DearmanKE Posted December 10, 2008 Report Share Posted December 10, 2008 the psi should be prety constant through out the rev range  whats the diameter of your crnak pulley? Quote Link to comment Share on other sites More sharing options...

Falken_KE30 Posted December 12, 2008 Report Share Posted December 12, 2008 What type of cam you aiming for? Â I can't see how a cam will help that much. i run a standard one and its heaps good, good power from idle to about 6500. maybe go for a cam that peaks from 2k to 6k? Â BTW, whay crank pulley is that? Quote Link to comment Share on other sites More sharing options...
styler Posted December 12, 2008 Report Share Posted December 12, 2008 check on this but i heard if you spin the sc12 or 14 superchargers too fast it melts the teflon seals, i think about 12psi was some sort of limit... Quote Link to comment Share on other sites More sharing options...
KE70--4KCZ Posted December 16, 2008 Author Report Share Posted December 16, 2008 i want something that is good down low so i don't need to rev it hard,  its custom made crank pulley   i was told they spin to 12000 or something like that i think Quote Link to comment Share on other sites More sharing options...
Des Posted December 16, 2008 Report Share Posted December 16, 2008 I was told 12,000-13,000 rpm is the safe limit for SC12's and SC14's. People have gone over that and had no worries and some people have. Quote Link to comment Share on other sites More sharing options...
SLO-030 Posted December 16, 2008 Report Share Posted December 16, 2008 check on this but i heard if you spin the sc12 or 14 superchargers toofast it melts the teflon seals, i think about 12psi was some sort of limit... Â Its actually the teflon coating on the rotors have been know to separate above 12psi i think. Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted December 16, 2008 Report Share Posted December 16, 2008 I have seen a SC14 run constantly at 14PSI. Soon as it went to 15 it started loosing the Teflon coating on the rotors. This makes the tight seal so I wouldn't push one past 14 PSI my self but to have longevity id go max of about 11 PSI ish  Also 12-13,000 RPM is correct.  Cameron Quote Link to comment Share on other sites More sharing options...
