    These numbers make no sense. To have 300 hp at 2700 rpm, that would require 583 ft-lbs at 2700 rpm, but you say that at 2400 rpm, the torque has already dropped to 320 ft-lbs. Time to revisit your numbers/assumptions

    CAT's output numbers are what I based my figures on. What it really produces I won't know until I dyno the engine.

    Orr..... The thread discussing installing a CAT engine in your Jeep is actually off topic.

    This thread needs a do-over. We need a very rich person to donate several identically equipped Wranglers and one of each of the forced induction kits so that a full and fair comparison can be done on everything from the install difficulty to performance

    Its hard to keep everything equal when testing power mods. Realize, we got each about a year apart. All the jeeps are 4.10 geared manual trans rubicons. The turbo was a 2door, the two SCs, on 4drs.

    BB had a lift and duratracs when the SC came on. Sweet Pea was bone stock. They were tested as evenly as we could have done it.

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?
