    May be a SC problem?

    I pulled the SC out of my 07 GTX LTD to replace the ceramics with jerry's metal washers. Before I took it out, the motor was onlu turning 6700 RPM. I know these are symptoms of broken ceramics, but they were fine before I replaced them. The ski only has 6 hours. What could be causing this problem? I was told that maybe the SC slip might be off? Sinds kinda weird for such a new ski.

    Fix the sc and try again... 07's have been notorious to slip and break with very few hours.

    So putting in the metal washers might fix this problem?

    Metal washers solve the problem of them breaking.

    Yes, new metal washers properly torqued will solve the problem of slippage and eventual breakage of the ceramics.

    O.K great thanks! And BTW when you say properly torqued you mean the front nut to 22 ft.lbs right?

    Yes! Then double check the slippage of the clutch, should be between 60-110 inch lbs. I usually have mine at 95 inch lbs.

    Looks under tips and under how-to's and find the threads about supercharger health, etc.
    You hold the gear tight and turn the shaft with a torque wrench. It will slip based on how tight you have the nut on the shaft. If you are installing new metal washers and torque the shaft nut to 22 ft lbs you really should be okay. Checking just reinforces the torque making sure it is in the proper range.
