    RIVA Intake grate

    OPAS Block offs
    RIVA Thru-Hull exhaust
    RPM's 8150 @73.8-74.0

    (New)

    2Rude Charger (already purchased)
    Riva RRFPR
    4" Fizzle Air Intake
    Fizzle Intercooler (already purchased)

    When you put your External Intercooler in you need to monitor your AFR's, and you will adjust them with your RRFPR, the next would be a flashed ecu and or valve springs to do 8600 rpms or more,

    Yea. only down fall is you're riding around on a polaris. You really want to be seen on one of those? Id rather be on a tiger shark.
    lol

    Any way question i have for you was your x charger and 42lb injectors plug and play? Did you have to change anything ECU wise? I was told that the map sensor would auto calibrate for the 42lb injectors and the x charger considering they were oem.

    I bet you would be afraid of being embarrassed by a guy on a polaris passing you by. The MSX is one of the best looking and best performing hulls ever built by anyone.

    You know how to make an RXP 8 to 10 MPH faster? Strip it and drop it all into an MSX

    BryanP - Been around Polaris my whole life and even raced for the Polaris team. Darts MSX conversion is fast and reliable and I even won a race or two on it. If it was as easy as plug and play from a RXP to a MSX I would do it.. However its not that easy...
