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
