    RXP Setup question!!

    I want to add a fizzle 4" air intake, riva rxp intake grates, and proberly riva sponsons, and a 14/19 3 blade skat trak prop. Does this sound ok to make a little faster and faster hole shots? I have the riva exhaust straight out the back on my ski already. I know there are alot of options to do, but obviously $ is a thing that stops me from doing alot to my ski haha. I just want to go out have fun and go a little faster than normal. Please give me your opinions on this! Thanks!

    Your on the right track Bro ! Search the classifieds first you may be able to save some mula there for the parts you need. Be carefull thou once the bug hits you its hard to keep that thing under control. lol... Soon you'll be like the rest of us.... walking around with empty wallets. For now the intake, the prop, and the grate will give you a little edge. The guys here should start giving you more options soon. The stage 1 will get you there with a noticeble gain along with a different S/C.

    3 blade will be better on the bottom end... and a 4 blade will be better on top end. Take your pick... you can't have them both

    IMO without adding power. If you increase holeshot w/3blade you will sacrifice top speed. 4" intake may help.

    If you want speed try this its cheap and won't leave you with extra parts if you upgrade from here.

    4" intake
    riva grate
    2 degree pump wedge w extended rod to keep your holeshot
    Some have had success with adjustable venturi(nozzle) with 81mm ring.
    Tweak trailing edge of the stock prop for 8100 RPM.
    Oh, and fill in the rideplate mounting holes.
    This will get you to 70mph or better on an RXP.

    You could use a 14/19, but if you decide to upgrade from here you have to buy another prop.

    Thanks everyone for your help. Man this just keeps getting more and more confusing ha. If I do one up grade then it kinda seems like it affects something else ha. I do like top end fast speed and dont want to loose that, but am wanting a little faster hole shots since all I have right now is my stock prop on my ski.
