    X model Supercharger impeller upgrade fit in 2006 Supercharger?

    I was wondering what is the differences between the two superchargers.

    Is the X model that much bigger or is it just the size and design of the impeller that makes all the different?

    I need more power in my 06 rxp II+ Green wheel, Shorty water box, r&d intake grate, 87mm r&d nozzle, Skat trak 15/19, External innercooler, custom 3" intake, 42 lb injectors, Wedge, and every thing else that goes with the Stage II

    Max RPMS 7730 74MPH mild chop
    Either the impeller is too steep or I need to upgrade the supercharger again.

    I want to hit 80

    Any suggestions?

    The X housing is larger.

    First you'll need more boost to turn that 15/19 SKAT or take alittle off the trailing edge, 80 with your set up won't happen.

    You'll need;

    1. ditch the 3" intake, install Riva 4" Rear
    2. Get Riva's adjustable venturi ( use 81 or 82mm )
    3. Rude Charger
    4. Riva(8500RPM)/Rotax ECU(8800RPM)
    5. Valve train upgrade
    6. 15/22, pitched to match ECU
    7. RRFPR
    8. 50 LB injectors

    you'll be 80++ if installed correctly

    The X supercharger gives you loads of power. I would get Jerry to look it over and install the ceramic bearings. Not to turn you off the supercharger, but I am having problems with mine, bearings or clutch washer blew, maybe a touchdown. I know of one other case of this on the forum. Again, I'm pretty sure we're the unlucky two in a bunch.
