    ride plate will give u 1-2 mphmaybe more, but it wond add 300-400 r's to the motor...there's something else going on maybe the tune didn't take or the pitch is way off on ur prop.

    I just tested at the lake and I hit 81 mph via iPhone gps. Not sure how accurate it is. Proposing like hell top end. 8720 rpm. I don’t know IF this ski is good with a wedge or not. I have deans plate, stage 3 intercooler tune, ribbon gone, intake, fuel pump, solas 13/18-pro cooling.

    felt very flat in power the last 1/2” of throttle squeeze.

    I found that if you put in a Riva I/C or a Fizzle 1000, use a Jim's cut ride plate and increase your S/C to 17,19, or 20 lbs. Add retainers and a big ass heavy duty clutch and a decent reflash or ECU upgrade, large fuel injectors and fuel pressure regulator you can run 85 GPS @ 8500 RPMs, and or 90 GPS @ 8900 RPMs … just saying Steve Lee

    I’m sure you can. Just trying to trouble shoot. I’ve been told that with my mods I should be 83-85 full tank.

    Maptuner x with full tank of gas and a jet ski rack with 3 empty gas cans (bad aero). It hit 70.6 mph peak but I pinned it for over 2 minutes and it was around 68 mph. Water temp was 82 deg. It was doing 8000-8100 rpm. I believe rpm is correct just too much aero drag and hot weather

    This was the setup except gas cans were empty. I think it will pickup 2 mph without the bad aero and few lbs in the back

    I just found my boost leak on the Riva ribbon delete. I was able to blow air through the original o'ring gasket indicator slot. Using a knife I was able to slowly pry off the Riva insert to find that all but 1 oring had snapped. I cleaned and reinstalled using six10 and will have to test it later this week to see if is sealed now.
