    R&D C3 Monster Wheel vs. Riva Stage 3 Wheel

    I just got done trying out the stage III SC wheel in my '07 RXP. I replaced the C3 wheel with the S3 - these are my results ...

    C3 Monster Wheel - 76.1mph @ 7800RPM 58 degree air / 48 degree water
    Riva Stage III Wheel - 76.0mph @ 7800RPM 58 degree air / 48 degree water

    The Riva S3 has about 10-15 percent better accelleration over the R&D C3 , but I didn't see any gain at top end. Both are good bang for the buck.

    was this a back to back test?

    These GPS numbers were taken with the exact same modifications with the exception of the SC wheels, obviously. They were taken one week apart in identical weather conditions. With both impellers, my RPMs topped out at 7800 RPM as I was running a bit too much prop. I hit 76.1 mph @ 7800 rpm with the C3 Wheel and was expecting to see more top end with the S3 wheel... I did not.

    Note: I started to see big top speed gains and more accelleration after taking 2 mm's off the prop and replacing the 2.5" intercooler pipe from my SC to my intercooler with a 2.75" pipe. + 1.2 MPH
