How is your gas mileage driving normal (yeah, I know, normal??? )??? Compared to stock motor?

 

gas mileage is about the same....light goes on anywhere from 200 - 220 miles.
Amazed because i've got my foot in it so much!

 

how big a difference is it from stock to the supercharger?

 

HUGE difference...more torque, and the acceleration rush (especially in 3rd and 4th gears)is mind warping. One of these days i'll time it but it feels like it gets to 120mph in like negative 5 seconds.
yea......i like it

 

I'll second what Barry said. The hp increase is nice. I check my mileage last night. I got 23mpg out of my last tank.
