Motor and Pump isnt everything its all about the hull and setup. How wet is the boat ? What is your pump pressure ? Is the motor at the correct RPM.

My guess is your speed would probably be about the same as dooho although at a higher rpm. Maybe a couple more mph but not a lot. Sounds like you're running a smaller impeller than dooho. More rpm doesn't necessarily mean more speed though.

ervjr, I just got my charger boat, I will look through my paperwork to find cam specs for my 454.
