When I tried the 7 with a 5 the belt started smoking at 5700. The boost was jumping all over the place.

Probably could get 25 psi if you wind it high enough, should be some big numbers. The accelleration would be unbelieveable.

Me too, I am heading to Performance Marine Monday and Tuesday with hopes of a day or two of Dyno work. Setting the DFI up and all. As you can see its really close. I should have the drive together Sunday SCX / SC, I already have the boat there, I took it up two weeks ago. We want to install the motor and do some lake runs where we can make the adjustments, Jason Saris has extensive Accel DFI experience. Along with his race experience, I think I drive really good have been running WOT on the lake since I was 5.. Seneca lake can get nasty, but nothing like the offshore experience Jason has as a National Champion. So as we venture into uncharted territory, I'm steering and Jason can be the throttle man, lol yep the boat is set up for the passenger throttle man.
