Thread: How much horsepower

    Does it take, to make a V-Drive 18 ft runner style bottom hull, lake layup, go over 100 mph.
    Thanks in advance

    I dunno hp numbers. But a decent BBC with 12 to 1 compression...decent roller cam and Iron 990's, tunnel ram dealio will do it. Prolly the right single carb setup will do it too. Lot depends on the boat and how good the bottom is (hooks).
    Remember that is at sea level type air. And after 100 mph it gets a lot tougher.

    Less will do it, in a 1900lb Hondo.

    Seems like a lot of slip with an 11-1/8"x16 prop :idea:
    Turning 6500rpm with 18's and a 16 pitch prop and 87mph gives you about 25% slip, are your numbers right?

    It took about 650 hp to make my Sanger run 100. The Canyon is much more efficient could probably do it with 550 hp.

    And probably less than that. Canyon's are very good boats.
