    Those are some good numbers. You fill the Rideplate holes?

    ur running pretty damn strong for not having an external intercooler... that's going to be your next source for more power... either add an intercooler, or when in doubt, ADD MORE BOOOOOOOST, lol

    That sounds close to what our ski is getting. My 15/20 is a 15/18 now and I have the RR SC impeller. Other mods are just like yours except Blow-off valve kit and SD Supercharger. I have stock intercooler. It was hitting mid/high 73's Friday and Saturday on a full tank and went 74.1 on the buzzer Sunday.

    If you got a external ic your down a little bit but u will be damn close if you clean up the bottom of the hull. Grate bolts, rideplate bolts, shaving down that stock rideplate sealant and so on.
