    SpeedFreeksracing.com can do it for you.

    You can get it done with repitching.

    Ive got one prop done that way.

    Reid's prop at the hydro drags had speed freeks mod.

    Eric (speedfreeks) has run 87 mph on riva ecu sc rxp.

    THats all i can give you as far as gains.

    I have a question about this mod as well. I am thinking I want to maximize my current mods instead of upgrading my x-charger with the 2Rude that I already have. I am undecided With my current setup, I am turning the 14/19.5 prop I have 8,100 - 8,140rpms. If I were to have Erik do the mod to the prop, would I gain top speed, or just acceleration?

    I'm pretty sure it's just shortening the hub of the impeller so the blades are closer to the stator vanes.

    Ahh. Gotcha. Makes sense. So now I'm in the same boat as the other people on this thread......what kind of gains does this provide? Bottom, top, ???

    I have setback done, by speedfreek, it should help with holeshot. I have not tested it because our water is in the solid form for 2 more months.
