    Aftermaker ECU with 14/19 4 blade?

    Has anyone tried one at high RPM, 8700rpm+ 15psi boost ? Just wondering how it would work?

    It's not enough prop for 15lbs of boost at 8700. I've ran one at 8700 with a stock x charger on an x-boat in the heat. Had a great holeshot.

    Thanks for the reply speedskixp. Was that with the stock nozzle? I was thinking it would have a great holeshot curious about where the rpm and top speed would end up with my setup.
