    Question 2012 RXP-X upgrade questions

    Howdy howdy.

    I'm planning on getting the new RXP-X in a few months. I just saw one in person this past Saturday and its more awesome in person that anything online can show. It sure will turn heads on the water.

    Stock, they scoot but like every guy on here, I'm looking for more. I don't plan on racing or anything and I saw tweeker's setup so far and it looks great. I think that's a bit much for me though.

    I'm looking for the ski to have plenty of air intake and sound good coming out. I know its still really early in the year so parts are still being perfected by companies like RIVA.

    What I'm thinking about so far:

    --Thru-hull exhaust
    --New waterbox? Gut the stock one?
    --I don't know if a remapped ECU or override module is necessary. Is it?
    --Might look into a new impeller (how do you pick pitch size? does rider weight have a big effect on it? should I just wait and see what other people find works?)
    --What else should I look into? Remember, I'm not racing, I just want a little bit more (basically a stage 1 equivalent)

    That should be it, I'll follow-up if I think of anything else.


    Thanks in advance!

    I already bought lots of stuff for the rxpx 2012 that should arrive in 10 days.
    Basically change the impeller to a 15/20 from solas.
    The intercooler is very small, check the gen 3 from riva.
    A must a 4' air intake and you could drp in a 137 ET compressor blade.
    Finally if you need more, a remap with a valve train upgrade.
    Thru hull - not available yet-
    Waterbox - TDR - sounds amazing

    I'd love to see your build progress with pics. I'll probably start with easy and essential stuff. 4" air, vtech remap, thru-hull exhaust and eventually look into a 15/20 impeller and a few other things.

    The PWC will arrive the 26 (with some luck), then i need to make the F#$%# 10 hours (probably in a couple of days)...
    After that i already have an airplane ticket to bring some new stuff from USA, (i hope RIVA launch the thru hull exhaust during my travel).
    All the stuff will be inserted around the 22/02 (at my return) and i will put pics and results on this thread. The built will be in less than 1 week and i will compare the skat 14/19with the 15/20 solas...., and i also have to race with my best friend on he’s Kawi 300 (with secrets stuff)...- I promise a video of this race too-

    Wanted to come back and add what I plan on doing.

    Nothing is too different from years in the past and with the mods I'm doing it'll basically be a Stage 1 ski.

    4" air intake
    Fizzle catch can
    v-tech remap by Jerry
    Riva rear exhaust kit (Just talked to them and they plan on having the RXP-X out ASAP.)

    After all that I should be getting 73-75mph...I think.

    Later mods that I might consider are the Riva X charger and a Solas impeller at 15/20r. These will only come once money is available which might be my fall/winter project.

    I saw a new x yesterday. What a wicked looking ski.

    Looks like there is more room to work on than my 07.
