    GP 1800 what’s your top speed?

    I have a 2018 GP1800 running a stage 3 Riva kit with a 19lb wheel. 8700 RPM consistently around 87 to 88 mph in this heat. Would like to hear some RPMs and mph. What you got.

    Riva stage 1 tune. Went 76.4mph on two different phone GPS. 96 degree Fahrenheit, 70% humidity, altitude 50ft.
    Don't have anything to read rpms other than the dash (was reading 7600ish rpms)

    81mph with Stage 2 with 8600 rpm limit - 13/20 impeller. Ambient was about 100 and humid. Half tank of gas. Will try again in cooler weather and 1/4 tank.

    Hi, I was hoping you can please tell me how much you weigh, how much fuel you had when you ran your 86mph and what RPMs do you have yours set at. Reason why I ask is cause I’m running the same Riva stage 2 as well and I can only pull
    off 81.1 mph. I weigh 250lbs, 3/4 fuel and have my RPMs set at 8500. Water temp was 88* outside temp was 106*. Your input would greatly be appreciated. I was hoping to see at least 84-86mph. ��

    I am surprised the ski will not rpm to 9k with the 19 wheel. What are your exact list of mods?
