    Anyone have an idea of how much these things weigh? I'm talking crank drive, brackets, unit, tube, blow-off valve, etc., combined. To me it seems like a heck of a lot of weight hung say 2 feet in front of the motor. That must change a bunch of balance considerations?........

    I know some of the strong runners are in the 50-52% range. I’ve done a couple that were in the 56-57% range but we had the engine centerline a little higher for rack clearance issues and it worked out pretty good. The rack is definitely an issue.

    50% on a promod?!?!???

    That seems impossible to me.

    I tried 52% at 1800 hp and it wasn’t happening. At 53.5 it was fine. I can’t imagine how higher hp could tolerate a lighter nose
