    05 R12-x Extra mph?

    Bunch of questions...

    I've got an 05 R12-x and love it! What can I do low dollar mod wise to make it quicker?

    Can I fill in the holes like the seadoo guys talk about? Is it worth it?
    Any info on the 5 degree pump shim would be appreciated.
    Would an impeller help out (worth the cash)?

    If I did get a Nitro chip, could I unplug it and take it for warranty work like normal? Can they tell if it had a chip?

    I was thinking about getting a stock intake grate and cutting the 2,4 bar out, this seems like it would help... NEED TO BUY stock intake grate.

    Thanks.

    I don't sell cheap chips for High performance.

    My Stg1 Kit is a fully programed Engine management system
    (with a data recorder) and CDI ignition system. It can add over 7 MPH gps on a R12x.

    It can be reused on other engines, not only a Honda ski.

    PM me for more info and pricing.

    Filling in the bolt holes is good for about .5 mph. The pump wedge is good for about 2 mph. Cost.....about $100. Modify the stock intake grate for better hook up and reduced cavitation.....

    I've not found a 5 degree wedge to be an advantage on a R12x. I have however used to fill the holes and ride plate rework to help it. The new R/p will replace all of this as skeg testing was used 1.5 years ago and a few things were learned then.

    I just finished with a boost bleed which gave me just shy of an extra 4 mph and much better acceleration for well under $100.
    Apparently, it seems it might have been a kit I copied that someone sells named SuperJim so you can look him up for one..

    Thats cool and all, but that will get old, and you will want MORE. Thats when the stage kit will be the advantage, If you cant add fuel, raise the rev limit, then your beating a dead horse, Ive been down that road and went with the nitro kit. You will def need a intercooler for the increased boost, it will be useless due to high intake temps in the summer.
