    won't rev past 6000 rpm no boost leak

    i have a problem with my 2006 rxp. it would not rev past 6000 rpm in the water, i know this could be caused by a boost leak or slipping supercharger. so i checked for boost leaks and didn't find any so i pulled the supercharger and checked the slip. the slip is 18 flbs (ET 68-140 ). i also checked compression and all cilinders are at 125 psi. i have fresh gas, and new spark plugs installed. aslo i checked the pump and there is no debris in the pump or on the shaft. i log my fuel pressure and it's also good ( 60 psi ).

    you are not making any boost at 6k rpm so im not sure how you know there is no leak. I can tell you my ski wont rev any higher than 6k when i blow a charge pipe off.

    all the hoses are tight, i had blown a hose before and when that happened i could feel the wind from the sc blowing on my hands.
    now i feel everywhere on the charge hoses and around the intake manifold and i can't feel anything.

    you know you can blow boost from the intercooler or a snapped intake manifold. You won't feel shit on the intake mani. It will whistle

    it will only be loud if you blow the coupler off the charger itself, i have blown one off the intercooler and it was no louder than normal

    i just took the front off the supercharger because i noticed a little oil on the sc wheel and inspect the oil seal. i took the nut off but i can't get the sc wheel won't come off the shaft.
