    Tested my Turbo kit

    I went out and tested the kit.
    First,for some reason boost was not stable. It went up to 10psi, 2sec, then 17 psi. Maybe the boost controller not working properly. I am using the Mark Hallman from my race car. I need to fix that.

    second, Rude rising Fuel regulator not going up with psi therefore running lean on top anything above 13-14psi, with riva computer and 50# injectors. What might be the reason for this?
    I set up the controller to 60psi then after 2 passes went up to 66 at iddle checking with the key so I lowered to 59psi, started the ski and went down on its own to 58psi,weird.

    I am using a 15.5/21.5 prop 80mm ring and rpms were in the 7600-7800 at 14psi and 8100 with burst of 16-17 but could not hold due to lean conditions. Air temp in the 80's high humidity.

    shouldn't I be all over the rev limiter with the 80mm ring and 20psi?
    Should I tweak the prop due to the heat in Miami?

    I did 1 pass and ran 80mph at 7850rpm sitting up on the ski.
    any suggestions?

    I will take pictures.
    A friend of mine did it for me.....
    I chose the turbo.
    I will do some more testing tommorow to figure why the RRPR is not increasing with boost.
    How is the boost in other kits?
    Should it go to 20psi in one shot or 15psi and the creep to 20psi?
    thanks.
    By the way it felt nasty
