    4", maybe 5" since your ski is so fast

    My exit nozzle is the back of the pump. After you lightened the cam my ski lost 17lbs of weight. That's impressive

    The one I have measured 88mm with no ring in it. The lip on the inside where the ring butts up to is about 85mm but. Its smaller in that section than some of the rings I have and you can feel the lip.

    Hmm I was asking because I need to pull down my RPMs and am going to run the lucky 13. However I don't want to machine the Riva nozzle making it useless. After seeing what gus went through I figure I've been living on the edge for a while and it's time to bring it back around 9k or 8800.

    I have found best results run the L13 cone with a stock rxpx/rxtx nozzle.

    From what I seen the larger rings still seemed to change rpm. I think even though the nozzle reduces to 85mm prior to the exit, the actual tip area size still changes things. I never played with the larger sizes much at all but.
    I would think with the Lucky cone you will be able to pull the rpm way down.
