    Cool What to do next? Please help...

    I wanted to get everyone's opinion, what to do next with my ski and how to essentially make it faster...

    2006 RXP
    60hrs total
    Supercharger rebuilt by Jerry less then 15hr's ago upgraded to green wheel impeller
    RIVA Pro-Series OPAS Kit
    Riva thru hull exhaust
    Fizzle High Efficiency Intercooler Kit
    Intercooler Water Filter Kit
    Riva Intake grate
    Riva air intake (was part of my Riva Stage 1)
    Solis 15/20R prop
    Bosch 42# injectors
    Ride plate holes filled

    Currently top speed comes to 76.2 MPH (GPS verified) @ 8080 RPM 1/4 tank of gas 75 degree water, low altitude.

    What should I do next in order perhaps to reach, or get closer to, the 80mph mark?

    Input greatly appreciated. Thank you.

    like mentioned your going to need a wideband and rrfpr if you go any further. the only options you really have is bigger charger, ride plate, and ecu

    I would suggest leaving it the way it is now, you have a pretty fast rec ski that does not require much for tuning and is reliable. Unless you have other Green Hulk members in your area you more than likely are one of the faster guys out there.

    Or you could add some of these,

    2Rude SC or Engine Tech SC
    ECU reflash
    valve spring upgrade
    RRFPR and or larger injectors
    4" air intake if you do not already have it.
    Speedfreeks or Jim's rideplate mod.

    All really depends on if you want to hit 80+ anytime you want or just when everything is "perfect". And of course everything needed is available in the online store.

    Switch to an R&D Intake Grate

    You think R&D works better?

    r&d grates are better for the chop water or rough water.. riva grates are best for top speed... when adding a grate may i add the r&d girdle and speedfreaks pump shoe protector are a big plus.... adding these with a riva grate .. its not going anywhere.... as far as a charger id go with a ET 127 or ET 137 charger.... the 140s are a bit more tuning to dial in properly and more maintence...

    An x charger, RRFPR and a wide band for tuning. The x charger is the biggest charger you can run without an ECU. You can run a bigger charger with the addition of a fuel controler and the stock ECU.

    I would do a rideplate mod next. It will be a good bang for the buck and won't take away reliability from the engine. The only bad part is the mess of the install.
