    what about the ECU, Thru Hull, correct prop, intercooler without these you are doing good to be running 76 ypu need to get the wallet out again to get the "other 3 MPH"

    Jim, you're joking right?
    76.7 is awesome for those mods. You don't kiss 80 until you go with the ECU and lightweight valvetrain.

    Yes, filling in the rideplate holes is good for 1+ mph

    Jerry that what shes running in about 8 inches of chop!!!! I thought the stage 3 boats went like 81 or so. I was thinking I would be at like 78 or so motors running 8050 and just under 10 psi boost. the motor sounds like a garbage can with the rear intake and exhaust I hope its normal?????? you said so !! LOL 15/20R is right there though!!!!Do I really repitch for 50 rpm ?????????? Mid range pull is incredible leaves my Ultra in the dust and my new GPR is not in the same game. although the GPR shure is fun to carve with,,,, its like a scaple I see why you want the rxp MOTOR IN THAT HULL!!!!!!!!!!!!!!!1

    Yep, the sounds of the supercharger is very pronounced with the rear air intake and the stage 3 SC. It sounds good to me

    I would take 1 mm pitch out of the trailing edge to try and get another 100 R's out of it

    Exactly......JimC, can I slap you now? JK. I'd be really happy with those speeds.
