    Difference between RXP & RXP-X? Are there differences after mods?

    I see in the catalog that the X model has a bigger supercharger & external intercooler. Is that the only difference between 215 and 255hp? Or does the catalog not tell us everything?

    There are also diferences in the fuel injectors if your simply talking about the engine and components. The ECU are mapped a little different, the revlimiter on the Xs are set lower. Also the Xs have a different pump and pump tunnel setup.

    They are all correct. Since Seadoo keeps things max speeds to around 68 mph regardless of HP, the modifications done with the tunnel, nozzle, and ECU mapping all support a stronger holeshot and acceleration while top speed stays the same. Once you modify them and get the speed up, pump stuffing becomes a problem sooner on the PX because the tunnel design forces that much more water through the pump.
