    GPR vs RXP hull

    Just how much faster is a GPR hull than an RXP hull with the same motors?

    I think it all really depends, if you know what you are doing. But... I would like to think the GPR is 5-10 mph with the same mods.

    So it would seem that I am only getting minimum performance from my hull. I am running 85mph @ 8600 RPM with an X charger.

    That's good to hear. I have done a lot of work underneath so I hoped I've done something right. I too was thinking that 85+ isn't too bad.

    This is a good thread!

    With the X charger and the rite ride plate mods i think 85 is achievable from an RXP.

    I'm at 82.5mph right now and i think I can manage 83-4 as soon as I get my mixures right. Running rich at 11.3 right now WOT.

    I havnt found too many direct comparison threads so lets keep this going and compair RXP v GPR with similar engine combos and see if we can get an answer?

    Just remember the GPR type hull has had many more years of develepment time as well... So it maybe closer than we think????

    The GPR hull shape is unchanged from 2000-2008.
    The RXP hull shape is unchanged from 2004-2012.
