Since we are using a centrifugal supercharger the more RPM's we turn the more power the engine will make. The engine has to be able to live at those RPM's though.

I wonder what would happen with 15-17psi @8100?

Another thing to consider is jet pump efficiency. I think that one you start getting much above 9000 the ability of the pump to process any more water is slim and would not be very beneficial. Atleast from what I have heard anyway.

9,000 plus is some serious rpm for our motors. Heck Nascar motors dont even last that long at those rpms. I think it would be pushing the envelope to the max as far as reliability.
I also have heard the situation that SpeedSkiXP stated on our pumps being able to process the water at those rpms.

thanks for the feedbacks, im thinking (if possible) to program the lerning key @ 8300 rpms for regular use and the other one to racing use, 9000 rpms but no full trottle more than 15 sec.
