I got my rpm question answered thanks for the input. Wondering about mileage with this setup, im not expecting anything great just wondering if the 14-16 range is realistic while cruising at 70-75mph?

 

With that set-up and a 6 speed I am at 14-15 no matter where I am, Highway or city.

 

sounds about right for me too

 

Is that reading off of the dream-o-meter (the number that the jeep gives you) or is that an actual number? I reset my tripometer everytime I fill up and also fill up to the top when I get gas. Then I take the miles I drove on the previous tank and divide by the amount of gas I put in and the numbers are almost never close. The jeep always reads more than what I'm acutally getting.

 

That is so true and I have been checking for over 20000 miles !!!!

I only have 33's and 4.10 gears with manual trans and drive very conservatively !!!!! I was only getting 14.9 mpg combined 245 miles divided by 16.5 gallon.

So yes!! Your economy sounds about right !!!!

I just installed the Ripp Supercharger and have driven 202 miles and still have 110 to empty !!! over quarter tank !!
The electronics don't completely sync up till 500 to 800 miles which should then improve more !!!

 

I have gotten 18 doing 65 mph.

 

did you guys recalibrate your speedos with the lift and gears? that would make a big difference in the assumed mpg...

 

Yup Dave @ Northridge did mine.

 

I am running 35's with an auto, 4:88 gears, my speedo is off by 10% very consistanly. My computer is saying 12 -13 + 10% means 13.2 - 13.4. I would say I DONT drive conservitivly.
