It's probably been posted, but I couldn't find it. What kind of mileage are you guys with the Hemis gettin'?

Hey Seer1 ... How you been ????

I just installed the Ripp Supercharger and Immediately saw a 2.5 MPG improvement on the in dash computer and that was 30+ miles in town and a little heavy footin it !!!!

For the money and time invested for fuel economy ........ The SC ( imho) is the way to go !!!!

dont know about a hemi in a jeep but my 5.7 in my truck gets about 13-14 city.

Are you looking at taking the plunge? If so I will be big time jealous!

I'm leaning towards the RIPP SC. Of course if I did that my better half would be somewhat less than pleased with me. Maybe next year; after she finishes digesting everything I did this year.

Go read the window sticker on a Dodge truck. 15 and 19 just like our Jeeps.

Im waiting till AEV does the 2009 5.7 Hemi.

You can expect almost the exact same mileage as the stock V6. In some cases guys are getting a little better.

That actually does worse than my 2006 4x4 2500 Hemi Dodge Ram Quad Cab, w/o MDS. I'm a bit surprised and there must be something else in play.

Hemi mileage...now 'that' is funny! If I could afford to replace my engine with a Hemi, I would never be concerned with the mileage.

Honestly I would expect it to improve. I really have to keep my foot in the pedal to keep it moving. When a rig is underpowered the mileage suffers.

Case in point. My wife bought a Saturn Vue: The 140 horsepower 4 Cyl got 29 mpg on the highway, the 250 hp 6 cyl got 30 mpg on the highway. In test driving the 4 cyl felt like it was really lugging all the time but the 6 cyl feels just right.
