unsinkable, I am thinking u will need 500 hp for the speed u want. Lighten up the boat as much as possible, race nozzle will help and tweak tweak tweak. |

Supercharging works great on a jet boat motor. The big thing is a centrifugal one works better that a positive style(roots). The engine does not need the low end torque and you only go into boost at higher rpms when the centrifugal ones work there best. Mine is 500 ci BBF with a Vortech (5psi) on it an it pulls a double A stainless aggressor at 5600/5700 rpm. It is kind of nice because at 40 mph in a large boat I am only turning 3200 with 10" of vacuum. Really I do not know of any downfalls but it takes a bit to set up. |
