    Gprsho, with these mods, how much mph??

    Hey guys, got a gprsho nearly done, I just want to know how much mph should this ski be able to do easily. Here's the mod list

    2000gpr
    Sho motor
    Ribbon delete
    R2 reflash
    Exhaust
    Water-cooled intercooler
    Bov
    Seadoo pump
    Riva ride plate
    Ss gp800 grate

    It has a stock prop at the moment because It just got installed but will be getting a much better one ASAP. So with the right prop what sorta speeds am I looking at?

    Cheers

    Gpr and mike1706 did like 88 to 89mph...it took a nice distance to get that speed but it was done,with a stock wheel and minus the seapoo pump

    yeah is okay man, and yes with a right pitch on your prop you should be at that kind of speed with no doubt, but i saw you are going to use a seadoo pump so is different thing, you going to have better holeshot

    Yeah that's right I'll let you know once I pitch my prop what speeds I get, won't be too long away

    your pump set up will bring down the mph, these speeds were done with 155mm yami pump.
