Well, here are the results since the s/c install. I finally went through a few full tanks of normal driving to get an estimate on fuel mileage with the s/c.
The results didn't seem right at first so I ran through another couple full tanks and got the same results.
Before the s/c, I was avg'ing about 14-15mpg with exhaust, cai, BB tune, and these 24's that weigh 90lbs ea. I was getting an avg of about 300-320 miles per tank before I would fill back up with about 19-20 gallons, mixed city/hwy.
Currently with the s/c (under normal driving conditions), I get about 400 miles per tank, which equates to about 20mpg. I did this through 3 full tanks with the same results. I expected a gain of about 1-2 mpg since the engine doesn't have to work as hard with the s/c, but definitely not the huge gain I'm seeing now. Of course if I'm on it, gas gets guzzled 10 times worse than w/o the s/c. But it's amazing the gain I get when I'm driving it like the avg person.

10,000 miles @ 15mi/gal = 666 gallons fuel
10,000 miles @ 20mi/gal = 500 gallons fuel

At $3/gal that's approximately $500 for each 10k miles that you save

So it pays for itself in 100,000 :hands: :hands: :hands:


BOSS - plans on driving 100k more with a SC

Man I want one.... I'm getting 15-17 and that was before the e-fans went in yesterday..... I should be hitting a solid 16-17 in the city now and in the winter I should be hitting a solid 18 once the AC goes off. I could be looking at 20+MPGs with the SC..... a man can dream.

Someday.......someday.

I wonder if I can talk my wife into it if I show her Boss' fancy arithmetic?

Blizzard - You also have a 6.0L AWD. JK has a 2wd 5.3L... I was totally prepared to spend the extra dough for the Denali, but I choked when I saw the estimated MPG's... I had to go with the 5.3L
