    x charger slip for 8650 rpm

    Hi, as the title says, what should the slip be set at for a stock x-charger revving to 8650? have an intake manifold mod as well not sure what this thing will do for boost at that rpm..

    Thanks

    X's tend to go around 10.5-11psi on stock rpm, so it would be safe to say you will be in the 13's at that new rpm range....Round it to 14....add 2 for preload and wear...so around 16 pounds, or 192 in/lbs of slip........my best guess.

    With these new Mac-master spring washes ... Getting 16 pounds slip is a pain in the ass ...

    May need to get an old collar and grind it down ...

    Regardless of max RPM, can higher slip settings yield any more boost on the X charger (or any charger)?

    Mine was running anywhere from 11.5 to 12.5 with the mods in my sig. Starting to slip bad now tho, good thing it was time for a rebuild anyways.

    No,higher slip will not give you any more boost...

    Ok that's what I've heard before...was double checking to see if that might be why my ski is, according to some members, "faster than normal". Jerry set my slip higher than needed.

    Once the SC has passed the slipping point the wheel is locked to engine RPM. If it continues to slip it will wear out the washers really quick and likely send bits and pieces through the engine when it finally comes apart if not detected. Bottom line is that if it's slipping it will wear quicker. If you get the clutch set too tight you will run the risk of snapping the shaft and then the gear and other pieces will drop into the PTO cover and possibly cause severe engine damage.
