    Twin Screw Blower Upgrade

    Okay,
    who's going to offer a twin screw upgrade, so that the roots blower limitation can be overcome???

    Nothing really changes until then...

    Still dont know if there is any truth to the ECU limiting the boost output yet either,cause if it is then it wont matter what kind of supercharger upgrades you make the ECU wont let it do its thing.

    At 11plus lbs of boost, that would be a pretty small "limiter."

    if it is an electornic waste gate then the ecu would be to control it.... if it's a mechanical one then the ecu has no control over.



    you could port the roots blower like what the do on the cobra's and lightnings to eek more power out of them along with the pulleys

    EXACTLY....

    or replace it with something that pulls up top.

    My guess, is that the aftermarket must first fleece the owners with small power adders first. Then, if the correct size exist, will a package come out...

    sort of like the turbo units now hitting the market for the RXP.

    There are ways to get around that ECU problem I'm sure if it exist on the 250x. I would go the route of porting the stock blower and throwing on a pulley first though.

    You could always call up Kenne Bell and see if they will come up with something. They have always been good to the F-body owners with their constant whining over there is no twin screw for them.

    Man that looks scary!

    How fast does your bike go with that blower?

    Is your insurance paid up? !!
