    Just put "RXPX" into the search box. You will get exactly what you are looking for. Good luck and ride safe!

    How fast do you want to go? If you just want a little speed to put you out ahead of the stockers just slap on a Riva Stage-1 kit and be done with it. There are tons of other options available as well!

    What really is your budget? The problem getting a PX over 80mph is you are going need a big SCers, ecu reflash(9.2K), AFR monitor, open loop cooling, injectors, prop, prv, BOs, air mods, exhaust mods, ARP head studs, headgasket, RRFPR, intake grate, etc. After all that you will need to tear into the engine and put some good pistons(RIVA, CP) in. The stock ones don't seem to hold up well. Atleast that what I have been seeing.

    Figure 6-8K, if you can do most the work yourself.

    Not to discourage your goal of 80mph. But if i were you, i'd just grab a new intake grate throw it on there with a 4in intake and call it good, oh and a solas prop. You'll be much faster than stock because of the grate.

    I am running 74-75 with those mods and I have TDR thru hull and I am very happy. No more speed for me. Plus once u get close to 80 you have to worry about over stuffing the pump.

    Yeah, Unless you really have to have a 80 mph ski. What these guys are saying is right on.

    Get a R&D intake grate, Solas prop, air mod maybe. You will be in the 74mph range and still have a warranty.

    Yes you will still have a warranty until you start messing with the internals of the motor and the ecu. And that was told to me buy a tech a velocity powersports in SC
