    supercharger issue... maybe

    here are the circumstances: 90 hours on a 2007 wake supercharged, new impeller and wear ring after sucking up rocks and sticks. I have replaced the supercharger washer mid-summer 2007 at about 35 hours. Recently had the oil changed and just noticed today after going too slow there is too much oil in the crankcase. I ran it today at 7000ft elevation; too much oil and high altitude.

    Here is the numbers: 6900 rpm maxed out 60 mph speedo, and 54 mph using the GPS from my truck.

    I'm hoping having too much oil is preventing the supercharger from doing all it can and I do not need to rebuild the supercharger. Or, that a loss of power from the high elevation is the issue.

    I really need help with this one and found nothing by searching.

    Thanks, Jerry

    Your elevation is killing your RPM's!

    Over filled oil can rob RPM as well. Get the oil half way between the two bends on the stick on a hot engine.

    The oil level is way over the two bends. I'll get some oil out of it and take it down in elevation to see what the deal is. Can I just stick a hose down the dipstick or filler opening to recover some oil? I might try to get the intake thing off to see if my supercharger spins free to determine if my SC is shit-pie. Thanks for the quick response.

    If your at least seeing 6900 RPM then your supercharger is fine.

    6200 RPM is a different story!

    Over the top bend of the stick is DEFINITELY causing you issues. Suck some oil out!!!


    Proper oil check procedure. Engine must be hot
    Let idle 30 seconds
    Shut it off and wait 30 seconds
    Check oil. Should be mid way between the two bends on the stick.

    just curious, is too much oil getting all over the supercharger parts and slowing it down or something?

    rotating assembly is slapping the oil...causing drag...
