    2012 rxtx impeller

    I just got my ski back in the water from replacing the ibr module, while I was in there I replaced the wear ring, I am running a solid 70mph on gps and im sitting on the rev limiter at 8,040 bouncing to 8,100 and then back to 8,040, the only mods are the intercooler and scom, I am wondering what would be the next step up in impeller pitch, 15/20? I know about the v tech but after dumping a grand on the ibr it will have to wait, thanks for any imput.

    Telling me to throw the scom away doesnt help on impeller selection right now, if I did throw it away I would be stuck at 67mph correct? any other mods I do now will be needed down the road anyway, like intake, and f/a removal, I am trying to get the most out of the ski without a tune right now, it's not a matter of saving up money, it's a matter of how much I want to dump into this ski!

    Formula29, go with the 15/20. Don't forget that the greenhulk coupon code in the forums store will save you 10% off the listed price

    The SCOM is a POS as noted, but in your case you need to keep the rpms below 8040, so put a Solas SRZ-15/21 in it. A 15/22 will be to much pitch with your stock 83 mm venturi nozzle and no other mods.

    I don't see one in the online store, so contact Jerry if available
