    90 MPH VXR at only 8200 RPM and less than 16 psi boost pressure

    Hi guys, I just wanted to share some progress updates on my VXR with you guys. I have recently built up the motor to include CP pistons and Carrillo rods. The valve train remains stock other than a set of RIVA cam gears.

    I'm in the process of dialing in the new MoTeC M1 ECU on this ski. It's absolutely amazing to say the least. Expect an entirely different thread on this topic soon.

    I have the Turbo Tech F5 turbo installed. In this video you see the boost is less than 16 psi (top right corner of dash) and RPM 82xx. The ski is way over propped at only 16 psi so acceleration isn't as strong as if I have it pitched for 8600 RPM. Once dialed in this ski will rocket to 90+ with ease.

    Many said it couldn't be done, many said the VXR was a terrible hull for high speed. I knew better, I stuck with it and I have proved those theories wrong. I have this ski set up so that it's smooth as silk cruising along at 90 mph


    GPS speed is at the bottom/middle of the screen. This is the MoTeC GPS which is extremely accurate sampling at 10 times per second unlike most hand held GPS units that will only sample at 1 or 2 times per second.






    More good things are soon to come with this ski.

    Nice job Jerry! I wonder why anyone doubted the VXR hull for speed?
