Ok I know that jeeps are not hybrids and going to get great gas milage, but I would like to know if I was to put a turbo, not a supercharger, what kind of MPG should I expect? Im looking at having 37 on a 2013 rubicon. The added power will be good but kinda want to get some of the fuel milage back.

 

Honestly, I'd guess the same or lower mpg. Turbos and gas mileage go together when matched with a small displacement motor (infill you start dipping into the turbo). Remember with that extra air you need more fuel.

 

I would say stock or close to stock mpg on 37 isnt too much to ask. Remember with more air and fuel comes more power there for less work for the engine to turn the driveline. If you turbo it make sure you start a build thread. I'd love to see it.

Give prodigy performance a call, they could have something in the works like all the other forced induction companies. Honestly it's all in the tune and how much you like to be in boost. I'm supercharged but have yet to have a good tune to run after 7 months of lack luster engine code throwing tunes for the sprintex supercharger. Hope that will change with getting a dyno tune date at the end of the month.

Hope you can get something figured out would be interested in your build!

 

Fuel mileage will depend on the tune and on your driving style.

I have an Avenger supercharger on my Unlimited JK with 37" tires and 5.13s gears, Up here at altitude, if I take it easy on the highway, I can see 17+ mpg but if I choose to take advantage of my additional power, that number drops drastically.

I think a turbo will improve your mpg ONLY if you can prevent yourself from mashing the skinny pedal.

 

Thank you all for the input. I came to basically the same conclusion that it would help, as long as I can keep my foot out of it. I will keep everyone in the loop if I decide to go turbo.
