    I have an 04 Rxp with the following mods *please tell me how to gain more top end*

    I have a Seadoo RXP 215 2004 model with the following:

    1) R & D Intake Grate
    2) R & D Short Air Intake
    3) Riva Blow off Valve with a Greddy Type RS Blow off valve
    4) Removed Resonator and replaced with Straight Pipe
    5) RXP-X New supercharger
    6) 42lb Injectors
    7) Green water restrictor
    8.Solas 15/20 Prop REPITCHED TO OBTAIN 8050-8100 RPM'S
    9) OPAS Block off Kit
    10) Oil Catch Can

    My ski is reliable now at this point and I would like to keep it that way as its my weekend rider...... so what I want to know for one.... why my friend who has done exactly the same mods all with the exception of the "Ride Plate Mod" which shouldn't make a 1-2 mph deal top end wise....Why he is faster top end than me??? I beat him by a 1/2 of ski link out of the whole and I have barely a little more acceleration than him of but is his 05 RXP with exactly the same mods faster than mineon top end.

    We Gps'ed my ski at 73 actual mph

    Next question is what is the most cost effective way next to gain more top end. Please help!?!

    You need an external intercooler for more power. And upgrade to a 4" air intake for the same reason. Make sure the BOV is not leaking boost. You could also have the rideplate mod done to your ski for 1-2 MPH. All of this should land you at about 79 MPH give or take a little. I'm sure others will chime in shortly

    +1 but if you get the intercooler, you'll need a RRFPR

    if you add the intercooler and intake..

    you will also need a rrfpr or rude controler...

    or

    if you are willing to turn the extra rpm you can go with the riva ecu 50 and the valve train... the you will have him out of the hole and top end

    keep up with the jones's

    You should be faster than 73 with that setup. I suggest getting rid of the blow off valve as it may be causing a boost leak.

    Remove that blow off shit and install a external intercooler and then pitch your impeller.
