That's it^^BadMojo said:I've always been a proponent of stuffing more air into an engine so you can burn more fuel! Supercharge that puppy!
Have you actually made noticeable power yet?On my 2010 unlimited I have changed the intake to k&n. Changed the exhaust to dual and bought the diablo sport chip. What else can I do to the factory motor to get more power?

Gears, Gears, Gears. Your 3.8l is doing about all it can do! Naturally aspirated. And if you have put larger tires on, without regearing, you have really killed the power that it does have. K&N= dirt; if you do any offroad stuff. I threw mine in the dumpster and went back to factory without noticable difference in power or performance. It just doesn't sound as powerful..

No supercharger on the Jeep (at the moment), however I have built a few supercharged engines, the last being a roots based Eaton MP62 on a Miata. Fuel economy went from a reliable 32mpg no matter the driving conditions to a whopping 25mpg if you didn't get your foot into it. Under boost playing around it got right at 10mpg! When you supercharge an engine you are adding massive amounts of air, which in turn allows you to add massive amounts of fuel to keep the air fuel mixture at or near stoic. I just can't see how adding boost to an engine is going to increase fuel economy. Yeah there is going to be more power in relation to the weight of the vehicle, but that extra power is coming at the expense of burning more fuel. Only way I can see to increase the power and fuel economy is to swap in a larger engine that is already more fuel efficient in a heavier truck, then you gain some in the HP to weight ratio and could see an increase in MPG.I don't have mine yet, but all the reading I've done says there is an increase in MPG?
I haven't got any first hand experience with this.
Do you have one?
Root or centrifugal?
Whats type of decrease have you had?
Yeah, and they may actually be on to something with the centrifugal setups...I haven't played with any of those. In theory it would be possible to move the torque curve down enough to actually bring the overall efficiency of the engine up to a point where your usable power range is in an area where you could see an increase in fuel economy. But it would require you to drive very very very responsibly...and where is the fun in that? You've got a supercharger!!! PLAY WITH THAT SUCKER!!!Thanks for that..Like I said, I haven't got any first hand experience...have only read results from others who have...
They pretty much believe that the engine is fundamentally more efficient...and are generally commenting on Ripps (centrifugal).
I'm looking forward to getting mine and getting it installed...unfortunately MPGs of any reasonable numbers will never be in my future with these 1600lb tracks:banghead:Yeah, and they may actually be on to something with the centrifugal setups...I haven't played with any of those.
