    75 MPH Sea Doo RXP 260 - Budget Build

    I thought I would share this set-up as others have spent much more and gained the same speed.

    1) VTECH Map Tuner
    2) VTECH Tuning Credit - Normal 8375 RPM
    3) RIVA Manifold upgrade
    4) Riva RRFPR (Set Rising Rate) (11.7 AFR)
    5) ET 137mm + 4
    6) Riva HD S/C Spring Washers (15 FT LBS SLIP)

    Intercooler, Intake, Prop and Exhaust all stock.

    75 MPH GPS @ 8300 RPM NO FREE MODS YET !!

    Align the engine, replace the grate, DIY 4" intake, fill and level the rideplate holes.

    ^---Best bang for the buck anyone can do.

    I have the same Mods but additionally with Springs & Retainers, Riva IC, DCC Pitched Prop, 4" intake, 1000cc Injectors and Athena - 80mph @8900rpms all day at 75 degree water. I think you are right on track-

    Judging by there being no valve train upgrades on his list I am going to guess that he has the 8375 V-Tech map. If he swapped the intake and/or intercooler he would probably have to re-pitch.

    I got the 8375 V-Tech map loaded. No valve train upgrades. I am trying to see how far I can get with the stock intake/ prop / exhaust without too much rpms.

    An intercooler and thermostat are next on my list, what do u guys think ?

    I think you are pretty close to being maxed out on the stock prop. As Fizzle said anything else you are going to need a repitch, especially if you add a IC.

    I was thinking of putting 1 or 2mm in the stock prop as I have done a few over the years. We run in a lot of chop and the 8375 is a good threshold for me, unhooking with that limit normally means the engine would over-rev to 8500 RPM. I would be afraid to unhook with the 8800 rev limit . I figure 2mm more prop at 8300 RPM, fill the rideplate and I should be at 77-78, no one around here going that fast on a ski.

    You can do a lot with the stock prop (repitched). It went just shy of 80 mph on my ski at 8900 rpms. (Cold day)
