    Hull is a 2008 gpr with true hull carbon seat full carbon kit (not on ski) has on stock kit for front bin custom painted inside of hull to match valve cover and charger engine bay lights and under water lights and nav lights for late night runs

    Motor is a 08 rxp with head work titanium valves and riva springs and retainers and balanced crank also have a head being ported and polish seadoo center intercooler 11 psi charger wheel 42lb injectors oem intercooler block off ,255 throttle body rrfpr boost gage

    Pump is out of a ho (soon to be svho ) spacer is taped for relief valves dual cooling kit for intercooler solas 14/20 no issues with prop as yet

    I missed it in your post that you stated you ran 71 so far sorry.

    I need to get a few more things for my conversion so I haven't ran mine in the sea yet just on the hose and also want a race seat like yours those are nice.

    KyleP, very interesting build. I have seen a lot of GPRXP's and they turn out pretty fast. However, if you had an 08GP1300 ski why not just mod & build it out if low 70's was your speed gain. I thought you would be getting like in the 80's with the Sea Doo turbo ... just saying. Good Luck & lets us see some final pics & numbers.
