    I've been wondering the same thing. Maybe not enough demand? Rude Performance might be a good place to ask this question to.

    The answer to threads like this are usually always "The 250s are relatively new and the aftermarket hasn't had the time to develop products like they have with the RXPs" (which have been out for almost five years now).

    Changing the charger is the easy part. Its the ignition or ECU thats the issue. Kawi units are locked and the only way around them is a complete new system.

    Skip, with a bigger SC wouldn't we also be blowing more gas into the oil?

    Changing the SC wil reqiure different pistons.

    The roots blower is not like a centrifical. Roots has instant and full boost that can help motor through the take off lag or stain of hole shoting.

    A centrifical will be low on boost on take off so you would change the pistons to comp for that lag.

    Just my thoughts though but still on a 250 you want to change pistons with any SC changes.

    That will solve that issue.

    Try this one.

    stock S,charger @ 12psi = 8000rpm.

    same boat except S,charger removed and turbo installed @12psi = 8350rpm.

    Everything else the same.

    I guess what I'm getting at is you still have to drive the blower.

    It dosen't. That 350rpm difference is caused by the power required to turn the SC at the same boost level. This was done as an experiment to see how the engine would run @ 12psi without having to drive the sc. The stock ecu and mapping was used and needless to say, it was fooken orrible down low due to the different requirements of a turbo v,s SC.

    Todd is turnin up the wick tomorrow with fuel controller.

    Should be interesting.



    And yes, the idea behind this development is to produce an upgradable watercooled turbine turbo kit for racers and performance minded rec riders at a price that isn't too scary.
