RIPP vs. Magnuson...SuperCharger Shootout!

[UselessPickles]

Looks like the Magnuson might not have as big of an advantage over the RIPP at low rpms as people seem to assume based on the centrifugal vs roots-type generalizations. Although, it's impossible to know what the story is below 2000 rpm with certainty based on this chart. But as I've already shown thanks to the magic of math, 2000 rpm looks to be a low enough rpm to be useful for general off-roading: http://jeeplab.com/showthread.php?33...full=1#post802

True, I am surprised that the RIPP pulls that well at the bottom, however, the Magnuson seems to have more power where i generally use it between 2,000 and 4,500 RPM. I drive a manual, and generally do not spin the motor up to redline when shifting. Daily Driver purposes, the Magnuson appears to be the winner; on paper anyways.

Just curious as to whether Sweet Pea and Black Beauty have had MPG recorded regularly since their respective supercharger installations? I use Fuelly myself, and am really curious to figure out not only which is better $ per torque/hp, but also which has better overall fuel economy.

I would guess that RIPP would win the MPG battle. Has anyone been keeping decent hand-calculated MPG records?
