Thread: 7000 RPM?

  1. #1

    7000 RPM?

    New riva racing impeller in SC, new oil pumps in front and rear housings. Stock intake and exhaust, and #42 injectors.

    The ski wont rev over 7000rpm....I cant spin the SC by hand. Ideas?

    What was the slip set at?

    Checked for boost leaks?

    Plugs are good?

    Plugs are new, slip is at 160in/lbs
    And how do you check for boost leaks? What confuses me is you can squeeze the pipe going from SC to TB at idle a LITTLE bit.

    Idle is around 1800rpm

    i made a boost leak tester that fits on the end of the blower and you just add air to it to pressurize the intake system.
