    yes my mistake. The 120,000 rpm figure is what the 300 supercharger bearings are rated at.
    a 300 Engine spinning 8800 rpm has a supercharger spinning 51,500 RPM
    at 9000 RPM the supercharger is...

    this vibration people refer to is actually compressor surge. Balancing the wheel to the shaft doesn’t rectify this. Using a good BOV reduces the amount of compressor surge (flutter)

    Roughly 45,000 on older superchargers. 300 superchargers spin 8% faster

    if you look closely at the clutch end of the 300 supercharger you will see the supercharger has grind marks they use to balance it. You won’t see such marks on the 185/215/255/260 superchargers.

    IMPROS just does the balancing. Art at Engine Tech can handle the rebuild and balancing.

    These superchargers are called “maintenance free” by Seadoo so Sea Doo doesn’t offer rebuild parts for them. Fortunately our friends at Rotax Racing provides a kit and that kit is available right...

    Do your research! You will see from your research that blow off valves on the Seadoo skis are not needed, on the Yamaha skis with a sprag clutch, yes, they are needed.

    He's all over the limiter now at 8180. He needs more pitch. If the 15/22 is too much he can simply depitch the trailing edge like I advised him to do

    That's the absolute worst BOV you can put on any ski. You are much better off without it.
    It's not recommend to run a BOV on a Sea Doo anyway. It's not needed due the the slip clutch design of the...

    I assume you have an FX SVHO and not a GP SVHO?
    You will NOT gain 7 mph on the 2019-2020 FX SVHO if you don't also do the ride plate. The stock 2019+ FX stock ride plate actually slows the ski down...

    Correct! The RIVA rising rate fuel pressure regulator I linked you to comes pre set, but it's good to always check it once installed on the ski.

    It absolutely depends on supporting modifications, elevation of your riding area, and many other factors as I mentioned in the above post. V-Tech/RIVA Maptuner tunes are the same.
