    Call B1
    Starkweathers boat is just like yours and he modifies the strakes to reduce lift.

    Default 1980's vintage Daytona with similar bottom

    I have a similar set up 30" set forward and 1200 hp that wants to porpoise at above 110 mph. We are trying to set the hardware and straight nozzle without a droop just right and not do any bottom work until the last resort. Chris at B1 is also helping me thru is process. Give him a call.

    Try moving the motor foward about 4 to 6 inches if you can.Also install a Wing.

    boat's not climbing. just too much keel lift. almost looks like an overcharge sometimes.

    it's not climbing. look at the attitude. compared to your shitbox, this is conservative. the whole boat hops. it's not moving up bow first. it's good to know you can tell if a boat's climbing by a still pic, rather than see it running in person.

    The nose is not climbing, the attitude was good, then the whole boat just slowly climbs up out of the water.

    We're very close to solving the issues, the old school droop snoop was caring the entire boat too high, which worked up to the 110 mph range on motor. When adding a 400 shot of nos the boat would drive out, hop, and unload. By removing the droop and replacing with a straight place diverter the boat now rides lower in the water and stays hooked up.Over charging doesn't seem to be the problem with 60 psi intake bowl pressure at 100 mph. Thanks for all you guy's imput, it seems to take all of us these days to diagnose these situations with the leaps and bounds these boats have made in the last few years. I did want to say that I never had experienced this poor riding performance in my home state, running 120 mph at 1500 feet elevation. This occurred at close to sea level in unfamiliar waters and no way to replace the droop at the time. Thanks again Steve.
