Most usable power lower in the rev range. As good as the rest at the top of the rev range. Twin Screw. More efficient but noisier.

Been known to do sub 5 second 0-60mph in a auto SWB 3.6 hard to believe but true. Talk to RPM Extreme or Sprintex direct.

Sprintex 3.6 versus 5.3 LS. Dig that V8 burble but you cant argue with the performance. RpmExtreme built both vehicles I believe.

Nice, I did look at Sprintex, though maybe not hard enough.

I think the Edelbrock is a better setup. The dyno chart will look the same. The fit is much better though and it is apparently, very quiet whereas the Sprintex is pretty loud. The blower itself is a nicer unit as well.

I wish I was getting 16-17 mpg. I'm in the 12-14 range.

I have a stock setup, manual transmission and tires aren't even as tall as OEM Rubicon KMs.

I understand that this forced induction will not help fuel economy, though I want the best balance of available power and the minimum of parasitic loses; Prodigy Turbo and RIPP were looking good, but the Roots/Screw type Superchargers probably provide better usable power at any RPM.

It would be great if I don't have to run 93 Octane, but there may be no way around that.

I voted on your poll. I clearly voted for the edelbrock, as that is what I went with. I don't think you will be able to get around the premium fuel requirement, unless the engine was originally designed for forced induction such as Ford Ecoboost.

My current setup prior to SC, and according to the dash readout, I am getting 16.6 MPG.

On a 3.6?! How is that even possible? I'm on one ton axles, 40s, have zero aerodynamics, and get better mileage. Have you tried detaching the gas pedal from the floor?

I'm just going by what the read out says on the dash. It never gets much above 14 mpg usually in the 13's and no I'm not a fast driver, my wife actually makes fun of how slow I drive. I have a 4in lift 35in tires 4.88 gears and a G2 44 front axle. I always wonder how accurate that thing is though.

And I'm barely squeezing out around 300mi out of my 22 gal gas tank which roughly comes out to 13.6 mpg

The E-Force definitely had the cleanest installed appearance; just looks like it belongs. I know that pre-ignition can be controlled with other factors than compression ratio, likely controllable by tuning.

I am really looking forward to hearing about how the install goes, and even more interested to hear about the results.

Dyno charts are great, but not very objective. Every Dyno is different, every Jeep has a different setup, temperature/humidity is different on the given Dyno run.

I look at all of these Dyno charts, as well as 0-60 times, though I am really less concerned with the most powerful/fastest forced induction. I want the setup that has the best power delivery, least destructive to engine and drivetrain, and most efficient to operate.
