    *PRE ORDER* Rotax Racing high boost supercharger impellers

    I just got word that these will arrive at the end of next week in limited quantities.

    They are proven to work with the Rotax Racing stock class and Racing ECU only. Further testing is needed to be done for those using the stock ECU.


    The larger injectors are required for motors with ported heads and a racing cam. At upper rpm's the stock injectors won't supply quite enough fuel. This will cause the motor to run just slightly on the rich side at idle, but not enough to affect operation except possibly when idleing for extended periods of time

    These are easily installed without machining of the supercharger housing.

    Price is $475

    Pre order now to reserve yours. Your credit card will not be billed until it ships.

    Thanks!

    I plan to do some testing on a stock ECU equipped ski and my A/F ratio gauge to make sure things are safe.

    Give me a month or so to get to this test though.

    I'm thinking, I'm thinking... Any extra parts you need with this thing? Would I have to do additional mods for reliability after doing this?
