    Unported EFI 1300 speeds

    I am trying to set a speed goal to shoot for so........
    What is your speeds on yours?
    As for engine mods, other than compression and bolt ons, NO INTERNAL engine work.

    Kirk my wifes 06 is as follows:

    1200 grate
    Pump shoe sealed
    R&D plate NON FF
    Jims milled head
    Jetworks
    Blue FF hose
    3* key
    VF III's
    Sonic Booms
    DF 14/22
    I think thats it.
    EDIT: EFI controller

    Best to date is 73.8 @ approx 7100.

    I need to try a 87mm nozzle on it and see if I can get the RPM's up. This speed was run on the rich side. The ski now has 6 hours on it but I havent had time to tune on it since I started my conversion. I think that it will run 75's with no problem.

    I saw Nick's (GPRGASM) run over 76 with a 1200 grate here in Fl.

    Best I ever got Elliotts to run was 75 before he ported it.

    I don't doubt he ran that fast Kirk. A lose setup with 800 grate and no tabs would get ya there I'm sure.

    I do not mind a little loose, but tabs will always be on my boats.
