    Rxt-x 260 supercharger

    I've been thinking of going to a larger compressor wheel and housing or even a whole new supercharger. The only problem is don't I need to run larger injectors and ecu to get the fuel and timing set. Was also planing on making up some stainless intercooler/supercharger lines to try to stop the boost lose in the stock rubber lines. I've heard good and bad about blow off valves and would like to get the real facts on bovs before I fit one in as well

    Have also heard both good and bad about the r&d grate for the 260. Haven't ran it yet with it installed. Wondering if anyone has ran the r&d grate and the stock iS grate head to head and could help or shed some light

    What about a min-rude? Is that a waste of money since the ski has a boost limiter?

    i did not try mini-rude, and have no idea of it's perfomance curve, but i suppose, it's useless until boost limiter exists.
    stock ecu will not allow significant bigger SC work properly
    I personally tried Rotax racing 137 mm wheel+front housing
    for example,rotax racing 137 mm SC whell hits the boost limiter as early as 7400 rpm - ecu is closing the electronic throttle body and it happens 5-6 times while accelerating from idle with WOT all the way.
    So,my opinion - aftermarket ecu is a MUST for bigger SC
