    Chris, on a bone stock ski with just the grate then you will benefit from the Solas 13/18 shown here

    If you were to add an air intake then you would want to use the 14/19R impeller.

    impeller question

    Jerry,
    Will I notice much difference if I get the air intake and 14/19? could I run the 14/19 without the intake?

    chris

    ps. did you have a chance to look at my supercharger?

    The 4" kanaflex intake set up will make a big difference in rpm. Very worthwhile mod. It will force you to get a new prop or repitch your old one.

    iv been running a 14/19 with nothing but an intake grate for nearly 2 years now, you will just have lower rpms until you mod some more

    Your horsepower peaks around 8100 rpm so that's where you want to run. Pitch your prop to run at this rpm and you will see your highest speed's and best acceleration. The 4" intake is good for 150-200 rpm I believe and that will equate to 1.5 to 2 mph. At about 150 bucks, that's the cheapest speed mod to be had. This and a 14/19 will impress you.
