    Wink Cayman 2010 RXT-X 260 hull with 2006 TURBO motor

    Well after the success of my turbo setup I linked up with a friend to build a bigger setup for his race team, as its not my bike I can't give too much detailed info as I did with mine.

    Presently we are testing in the ocean, so far 75mph on the limiter @ 9100rpm 21-22 psi still tuning

    what ecu are you running?
    I am assuming an older ecu since there is no brake and there is a throttle cable. interesting

    Seems like you need a much larger prop, what prop are you going with?

    15/22 now pitched to 24 best time last weekend was 76.5 @8,400rpm with a 81mm ring with 21psi on race fuel, every thing on the bike is almost perfect and runs flawless but still a bit slow for the set up.

    Since the last update we did some major changes :

    the turbo setup is now in a New 2012 RXPX hull (the other hull never felt safe at high speeds)
    activated the anti-lag on the Autronic ECU
    water/ Alcohol injection +104 octane
    hi/lo boost setup LO 20psi and Hi set to 26 pounds

    So far we managed to run 84MPH at about 8,500rpms 98 deg temp and about 1 to 2 foot chop
    ,...We did a rebuild for last year race season and changed to 8.5:1 wiesco pistons, we had in some CP 8.0 before but the rings were worn pretty bad and we couldn't source any new ones as they discontinued that type


    The ski has been [s]flying[/s] running pretty well the ski won't stay in the water to get the power down but we did some improvements to the hull adding trim tabs etc. hopefull that works other than that she flying. we ended up changing the turbo to a bigger Custom Pression 58-30 dual ball bearing
