    Another 89 mph RIVA Stage 2 GPR built by GreenHulk Garage!

    Check out my latest video. I built another RIVA Stage 2 GP1800 running 89+mph.

    I installed the RIVA pro series cooling kit and go over it in detail in this video along with a few other modifications to achieve this speed.

    If you aren't already a subscriber to the GreenHulk Garage Youtube channel please subscribe. We have lots more content coming.
    Coming soon, a back to back comparison of the RIVA Gen 3 and Fizzle Y1000 intercoolers.

    DETAILED Yamaha SVHO Pro-Series Cooling & Gen-3 Intercooler IINSTALL + 89 MPH!

    Air temps were 79 degrees, no wind, and no current as I was in a short canal with locks at both ends. The ski was turning between 8900-9000 RPM. I also weigh 150 pounds.

    Not unbelievable at all. Numerous people have been into the 90s on the stock supercharger impeller. Over the last month I've done two Stage 2 2021 GP1800R's and both ran 89+ GPS VERIFIED (89.4 & 89.21).

    The air over there is quite rich of oxigen ! Aniway what map are you running and what pitch are you using to reach 90 and 9000 rpm ? Here with the above mods and 13/18 we can reach max 8600 rpm and 86 . Do you depitch the impeller to reach those numbers ?

    we are at sea level which definitely helps us out. I’m running the “Stage 2 9200 AGR” MaptunerX tune. It has more timing which adds a little more power. I’m using an out the box 13/18 to turn almost 9000 RPM

    What fuel octane does that AGR tune require?
