    X-charger and 9000rpms

    Anyone ever reach those rpms on x charger?
    Don't know if I'll make enough power to get there on just de-pitcing the 15/20 with the x charger and was wondering if anyone is running this set up.

    Would be very interesting to see the boost @ those rpms? i'm on 12.5psi @8420 so 13.5-14.5 should be on the cards @ 9000!

    If you don't mind me asking, what pitch and what nozzle did you use to get there?
    Im trying to get a feel for what I'm looking at for prop and nozzle combo.

    Might have to go 85mm nozzle, who knows.

    I'm @ 8420! with stock 83mm nozzle anf untouched 15/20R. I think a three blade 15/19 may be a better option for 9000rpm for the x charger.

    15/19 3 blade is bigger than a 15/20R 4 blade. More like a 13/18 3 blade on an 85 ring to get those revs..

    You can spin 9000 with any charger with an ECU with a limit that high and a properly pitched prop. With an X Charger I would guess about a 14/19 (4blade) or smaller.

    Maybe a 15/19 pitched 4 blade with a 85 nozzle as my baseline wouldn't be so bad.

    Ill keep you guys posted on what I find as soon as I get numbers.
