    Looking For More Power

    I own a 04 sea doo rxp and i am looking for a complete package power upgrade. I am in need of some info. Has to be reliable and i dont want to rebuild it every 30 hours, like the rxx. Had it and was a pain in the ass. Possibly a turbo or larger supercharger with fuel injectors and upgraded ECU. Any ideas let me know?

    A good setup is a stage 2 type of modifications along with a 2rude supercharger, 42 lb injectors and a rising rate fuel pressure regulator. Easy 80+ mph all day long with the stock ECU.

    In case you don't know what a stage 2 consists of you can read about the different components

    If you want your ski to be really nasty just add the Riva ECU, 50 lb injectors and valve train upgrade to the above components.

    Also, you are better off with the Riva rear air intake.

    The only thing bad about going with the Riva stage2 "kit" is that your paying a premium for a number of parts that in my opinion are overpriced. Below is a comparison of what you could get for the same money but piecing the kit together yourself. All the items I mention are available in the online store, and can all be ordered here.

    Riva Stage2 - $2900

    1) 3" front Air
    2) Stage2 S/C impeller (8-9psi)
    3) Intercooler kit (overpriced)
    4) Rear Exhaust
    5) OPAS Blockoff's (cheapest blockoff's)
    6) Intake grate
    7) Impeller
    Wedge
    9) Sponsons


    Boostaholic Stage2 kit.

    1) Riva Rear Air $399
    2) X-supercharger $699 (10.5-11psi)
    3) Fizzle Intercooler kit $429
    4) Riva Rear Exhaust $250
    5) RE Opas Blockoff's $335
    6) Riva intake grate $129
    7) Riva 15/22R Impeller $299
    Riva pump wedge $109
    9) Riva sponsons $299
    --------------------
    $2948

    You get ALOT better performance, and a number of the peices are far superior to what is offered in the Riva kit. I would guess you'd see a 5mph increase over the Riva stage2 kit.

    don't forget you need a RRFPR or upgraded injectors for boostaholics stage II kit. And I'd ditch the Riva sponsons..

    After starting as a noob on this site this season myself perhapse I can lend somethings. The only mods I did to my ski that added a real noticeable difference in performance were, the jFizzleJR XS intercooler kit, and the upgraded SC each installed seperately and tested those mods you could feel the rest in my sig you could not feel a noticeable difference. Even racing against my test mule an FX15 the ones that only made a noticeable difference were the IC and the SC.

    If I were to remod a ski I would do the following
    4" home made air filter kit
    Prop I like the 3 blade for accelleration
    rear exhaust cheap and sounds cool
    XS Intercooler from fizzle
    Some SC upgrade I went greenwheel good enough for me
    42 lb injectors
    If you get porpoise then RE blockoff's only if you do though.

    I hope your right.
