    When Might He Be Back

    Well you see,,,,,,,,,,,,,,,,,,,, there is a problem............................ with the sho being a new ski and all, yamaha has not worked out all the kinks in the electrical part of the ski. Jerry is test driving the ski and it wont shut off............ , so it might be alittle bit before he post because he does not feel like jumping off the ski at 68 mph . LOL just kidding

    I HOPE TO HEAR GOOD THINGS THIS WEEK FROM JERRY.

    I think Jerry said about 210hp, and as I understand it so far, it should fit (but some mods may be in order)

    210??? Thats it. Is it a belt driven supercharger?

    66 mph and 210 hp is it, Yamaha doesn't want us to hurt ourselves

    It's a centri based supercharger, NOT a root style.

    A root root style has a dispersed powerband, whereas a centri has it in the upper RPMs. Yamaha did this right. They bumped up the cc's on the engine, and use raw displacement to get out of the hole, until the supercharger engauges with an additional 6.5lbs of boost.

    Boost to me is completely irrelevant. What is the CFM of that centri-based blower, THAT is the tall tale sign. How much air volume is it moving, boost means nothing.

    Yamaha is playing nice with the 1800cc block and a centri blower at 210hp. That block and that blower can split the 70s wide open, and with no problem I met add. As I stated before, and I say again...

    You can not place a 1.8 liter engine, in a sub 1,000 pound ski, with less contact patch (when on plane) then a honda civic at three times the weight, and the civic can do 130mph plus at 3 times the weight WITHOUT a supercharger?

    I agree with Jerry, when this thing gets unlocked, its a monster on the water, you watch. It will have no problems pound for pound running down any other production ski in my opinion. Its got an additional 300cc's of attitude to pull from.
