    Is there a supercharger better than a turbo kit.

    Hi all,

    Just want to know if there is a supercharger better than a turbokit?

    Maybe stupid question but I just want to know.

    Also for people who installed a big supercharger what is the difference in terms of consumption with an X wheel supercharger.


    I hope I got myself understood as I'm french

    bigger the charger the bigger the injectors the more fuel consumed.

    turbo makes more power but the bigger the turbo the greater the lag until the slingshot hits... some call it lag some call it giving them a head start

    big charger is big holeshot and more power to turn taller prop for higher speed.

    Think the biggest SC out there right now is the ET Race setup.
    Engine-Tech ET70/145 mega-charger This is the big daddy of them all. This is a ready to install supercharger made specifically for racing. This supercharger makes an astonishing 18+ psi of boost @8600 rpm and nearly 20 psi @8800!!!!

    I've never had a turbo set up so I can't say they would be as good or not but the big boost s/c that I can think of would be the Rude 3, C kit, Engine-Tech 68-140 Extreme LE, Engine-Tech 70-145 Race edition S/C LE. I'm sure there's more out there too.....

    Thanks all for all the great response.

    I keep seen people dying to get a turbo kit, but I was sure that the biggest the best supercharger could beat a turbo one.

    I wanted to go for turbo but when I saw the kit befor buying, I wanted your all opinion.

    If you have more information turbo VS Supercharger please keep me or US inform.

    Before knowing this site I was going to sell my RXP cause I had problems with it and couldn't ride it offshore.

    Now that I found greenhulk, I have a nice setup and everyone in my island especially the ULTRA is freeking out .

    And I only have a small setup.

    Soon I will post an HOMEMADE block off Opas that is really good on the RXP.

    I will keep you all inform on a next post.


    Once again thanks all I hope I'll get my rxp better with your knowledge

    WOW that must be hard to handle lol I'm doing mix offshore and no waves sea.

    But I can tell you now that with my small handling setup strak tak prop to cut waves, R&D impeller, and homemade block off, I'm killing the waves.

    It's just awesome it looks like I have a new jetski in terms of handling.

    Anywayz let's just don't go out of the topic

    Turbo is the way to go,Big power, less Gas comsumption ,You don't have to deal with washers anymore
    and with the right set up no lag.

    For the size turbos in these skis' there should be very little in the way of lag. Turbos are good for a couple reasons. One, its free power! With a SC your using power to make power because there is always a little bit of parasitic draw from the engine... Having to turn something else.... With a turbo there is a slight power loss due to exhaust back pressure being higher, but the gains far exceed the loss!
    2 - Turbos are easy to tune to your liking! A manual boost controller is all you need to go from gas saving, cruising mode, say 255 HP, and then with just a turn of the knob, now your in I'm going to smoke your butt mode. Maybe 300+ HP. Of course this is all a very delicate and expensive balance between tuning, AFR's, injector mapping, and boost!
    3 - Last but not least.... MAINTENANCE!!!!! Turbos are a ton easier to maintain!!! As long as its getting good oil, Exhaust temps stay under 900 F, and you use a good blow off valve, you can beat on it all day with no problems... No washers to change, clutches to wear out, or springs to shim!
    In MHO turbos are the way to go! Wish I could afford one for myself!
