    The Lvl1 kit is about as much as you can do to it. The problem with the DI's is that they require a lot of re-mapping and configuring even to squeak a little more power out of them.

    A couple things you CAN do..
    1) Install Jetworks valves in the exhaust. Give you a little better punch
    2) True the hull, install a 97xp Ride plate, give you a few more MPH
    3) Go on a diet lol.

    That is true! the 951DI`s are very complex electronics...
    you should be going 63-65mph @ WOT, whatcha looking for?...PR...

    i would like too see mid to high 80's. i know that prolly not possible with the rx di.

    after i get my next car i hope to buy a 04 rxp and stage 3 it with nitrous( the kit is adjustable from 100-200shot).

    that prolly wont happen for another 3-4 years cuz i am only 17

    You'll be fine.. in another 3-4 years half of the OEM's will be producing 80mph skis if the HP war keeps up..

    But seriously, you will NEVER see that with your DI.. Not unless you fit a different powerplant in there.

    Yep...never see it with a DI...or any 951 for that matter. It's simply too small of displacement for the speeds you are hoping for.

    I think you can do it with a 951.. Warner's ski is high 70's. My ski's alltime best is 73.3, and I am pretty mild on the mods.. I think one can go 80 on an XPL Hull, but it's not gonna last long..

    generally with the 1050 big bore kit how much hp do you gain?

    i know with the level one i will be around 68mph, with noticable low end.

    end lets say when my motor blows it has about 140 hours. i go to sbt and get a new motor are these any diffrent hp wise then the stock di engine?

    I had an Rxdi.

    Unsnap your air box lid and slide it away from the throttle bodies. Pull the flappers off of the carbs.

    It will get to top speed in a hurry.

    Warner's is high 70's? That's good...but where are you going to get another 10 mph out of a 951? The guy said mid to high 80's...just ain't gonna happen or Mel would have already built it.
