    12.6 PSI at 8700 RPM's for the new Rotax wheel VS 16+ at 8700 for the Rude Charger so it's not even close.

    I saw these dyno results months ago and i find them odd.
    The Rotax B kit used to be advertised at 300+ HP and now they only claim 276

    All the HP numbers seem low to me.

    Although Rotax Racing makes some nice products, their "new" supercharger is not in the same class as the new Rude Charger.

    Rotax uses the same sized housing/compressor compared to the Rude that requires a completely cnc machined re-machined housing to accomodate the larger compressor wheel.

    Remember that there is A LOT more to just boost numbers; It is also the amount of air that the compressor can flow!! In other words you can have a small compressor output 15psi and a larger one output 10psi and make a ton more power with the larger (10psi) compressor.

    It comes down to the amount of air that the unit can flow and how much latent heat is produced in the process.

    the "new" rotax one isn't a stock sized housing tho, even those the housing isn't machined... i wouldn't say the volume of the NEW sc kit is stock since there's a spacer.

    rude and b-kits machine the housings, Rotax adds a spacer between the housing halves.... obviously a more cost effective way of selling to the masses and the everyday joe.... just one more thing to worry about tho that your spacer isn't sealed properly and not leaking any compressed air.

    it's definitely not a RUDE or B-kit charger type of territory, but i am very curious to see how it measures up against a riva stage 3 charger
