    Anybody else using a VX prop on a GPR

    If so what nozzle are you using? I have pitched down the VX prop a couple of times and still am not getting the rpm I think I should on 1390 GPR/big hub pump/85 nozzle. Thinking to trying 87 nozzle but everybody says that is not the ticket on a big hub pump, but maybe it is with a VX mod prop.

    I have a prop done by Impros. Its a YH-CD 15/22. The hub size is large. (05 and up pump) I mention that because I'm not sure if a stock VX is large hub or not. Anyway, its been used with great success with an 88mm nozzle. I should also mention I bought both from forum member N8R who went 84+ with them.
