    Bayou Princess new best speed

    I just got off the water with Carey's ski and ran a peak of 76.2 with 1/2 tank of fuel and could hold a solid 75.8-75.9 anytime.
    It gets there quick too

    Lake temp 78
    Air temp 84

    As the fuel got down to 3 bars the ski would porpoise preventing me from getting good numbers

    The only changes since the last time out were the installation of the Vortech impeller, filled the rideplate holes and added the Riva high flow hood.

    To recap, her mods are:
    Complete Riva Stage II minus the wedge
    Riva hood
    Riva pro blockoff's
    Skegs
    Filled rideplate holes

    The hood works very well as i saw no heat fade. Before the hood i would see 50-100 RPM drop by the time i got low on fuel.

    It will be interesting to see what the new Rotax SC impeller and 42# injectors will bring

    I want to get her ski to go as fast as possible with the stock ECU.

    Hopefully the A/F ratio will be safe enough to run the RR imp with the 42# injectors.

    I firmly believe that with the RR ECU, RR SC impeller and 42# injectors i could run 78-79+, but that is too fast for Carey.

    8100.

    You got's to try Franks Riva IC too... .and you need to tweak out a 15/20 to run 8400 RPM's then you will see

    Could you run the #42 injectors with the stock ECU?

    I sho hope so Heck, JK is already doing it without that stuff!

    If I didn't already have the RR IC, I would do the Riva IC. But to me 50 RPM isn't worth going through all that hassle again and cutting my hull.
