Ok this test is in the books. Here's what you can't tell from the video -

The two units run almost the same time. How they run it is different. The power delivery with the Magnuson with their torque curve is different from the RIPP. Both are very fast. The Mag is like a freight train the moment you hit the gas. Power is even and seems to build endlessly. You can see that from their horsepower curve that we couldn't get to "crest" at 6500 rpm. (in the magnuson thread)

The RIPP on the other hand is more finesse power as you mash the gas pedal. More delicate at first, then the power build over 3k rpm is steeper than the Magnuson for more of a "shot out of a canon" feeling.

Had the trucks been side by side, I think the Mag would have lept out in front at first, and then the RIPP would have closed the gap as the blower goes nuts in the higher side of the RPM band.

As far as who would win a race? I think it would come down to the pilot.
