    jmatak9's 250X sleeper project

    Well let me just start by saying a big thanks to Skip! Without his help (installing & Tuning) , this project would not of been started. Thanks Skip!
    Thanks to Rogue for a putting out a very nice Pulley.

    I decided back in november 09 to mod my 07 250X, I never thought I would get to achieve the speed that I have recently attained. Skip installed the following:
    Riva Plate w/ mod, Flat Filter, R&D Catch Can, Rogue med pulley set, HP Fuel Pump, 550cc Injectors, Impros Stage 2 Impeller, pump mod for dual bottom feed i/c mod, built & tuned by Skip.
    Skip posted his "Ultra Pulley Match Up" in the "Tech Tips and Info Section" http://greenhulk.net/forums/showthread.php?t=116292 and used this procedure for the install on my boat.
    The fastest run I had on the boat after tuning was 72.0mph GPS on a full tank w/ (200lb rider), 76 degrees on flat water, after that it was consistant 71.9 mph at 8050 rpm's. The prop is definetly going back to Impros for a more aggressive pitch. I would also be appreciative if anyone had a 260X prop to send my way to compare to the Impros mod. and compare runs on both props, I would only need the prop for one flatout run, before I drop some $ on a 260X prop. Well this is where I'm at now in the 250X sleeper project. I will post the results again after I recieve my prop back from Impros next week.
    Joe

    so, why'd ya buy all the other crap then?


    all joking aside, how do you like the rogue pulley? I haven't heard of very many people running them. Did you buy the pulley, and tension as well?
