    How to get 80+ on my Stage 3+ RXP 215

    I own a very nice 2007 Seadoo rxp 215 Stage 3+ now and want to get it above 80.
    This ski was born a true Stage 3 Riva racing boat. Never touched water stock. $25,000 back in 2007. Been through tons of hours on the first engine and now has a 2008 engine with 38 hours and cluster to match engine. What are the main mods I am missing that would really push this thing over 80 into the 82 range? The speedo is showing around 8500ish RPM's I believe. Will the stock display show a 9200 RPM or can this engine even be pushed to that since it has the Riva 9200 ECU? Any help and input would be awesome. I want to take it to Duke to get it really dialed above 80.


    List of mods:
    -Riva ecu with 9200 RPM limit
    -50lb injectors
    -Seadoo 628 cam
    -New external inter cooler
    -X-Supercharger
    -08+ oiling system for supercharger
    -Riva cold air intake
    -Riva racing adjustable sponsons
    -Riva racing Pro series OPAS block offs
    -Riva racing intake grate
    -Riva racing stainless impeller wear ring
    -Riva racing/Skat-trak 15/19 swirl impeller
    -Riva racing interchangeable Venturi nozzle
    -Riva racing 2 degree wedge w/adjustable vts rod
    -Custom gutted and shortened waterbox
    -Riva racing thru-hull exhaust tip

    Built head spinning that rpm, flywheel bolts, bigger charger, fuel pump, bigger injectors, open loop, ride plate, intake grate with pump shoe protector and griddle. Basically a lot.

    15/20 was the first thing that came to my mind. Can I have my prop repitched or need to get a new one? The RRFPR defintely seems look a good add, and the XX Charger I'll add as soon as this one needs to be rebuilt again. What about the ride plate mods? I've heard of Jim's working wonders on ride plates, I'll have to see what RIVA put on their, I can't recall the plate on there now.

    On my 04 the Riva plate was the fastest. For me at least

    If your going for that much, you better monitor your AFR's for sure as you could destroy the engine is one WOT pass if the AFR's are off. As well as everthing everyone else mentioned
