    Tap @ 2 oclock and 10 oclock positin on the 2 inch spacer for a 3/8 npt to 3/8 barb fitting.. Use straight npt fittings because the 90* fittings are more resrictive.. If your planning on going over 85mph your also going to have to drill holes in the pump shoe...

    Beerdart has a good way of doing it as well without the jetworks valves. That 2" spacer is thin, so use a smaller size drill bit, then cram that fitting in there, you want a tight fit. I may have one already setup via the way BeerDart has it if your interested.

    Ok ok.. Sorry joe.. Depending on you pump set up, ride plate angle, and prop you may also have to drill the shoe.. Its a good idea to put a pressure gauge in the spacer to see where your at.. If you want to take a ride to Asbury ill show you a bunch of safety mods and other things that are a must if you plan on pushing a gpr hull over 75..

    We are pretty sure the Riva ones will, if you put too much pressure on them... somewhere around 64psi.

    Can you elaborate more on the pump shoe holes? I have BD's relief setup already and knocking on the 90mph door.
