    Need advise on nozzle sizes for GPS run

    I have a 2006 RXP w/ EFR turbo have been 85 MPH but feel I have alot left, I did that with a 85 venturi ring and the lucky 13 pump cone. Have heard people say stay with 85 as it doesn't load up pump as they say going with 82 or 83 loads the pump up bad. But have heard going with 82 or 83 ring would also help MPH???? Would love to hear some feedback on this as would love to know trying to get one last good GPS run in for the end of the season. Thanks

    I heard of guys running 79 mm rings with turbo RXPs and stock cones. Add 2 mm to the prop, have all the spacers for the cone with you and rings from 80-84 mm and go to the water and do some testing-- each setup is different.

    Thanks for the information. Would you recommend putting the stock cone back on? If I try the 80 or 81 ring.
