I get about 16 mpg with city/highway driving. If I'm out on the highway for a long trip I can get about 20 mpg. Really, at this point I have just realized my car isn't a gas saving car so when I feel like stomping on it I just do it and not worry about it! ha ha ha

on a straight stock 03 gt motor with 3.27 gears I get 8-11 city, 13-17 mixed and 20-27 (got 29 once) highway. Like jjtgiants said, it's not a fuel efficient car by any measure. When you want to waste 10 bucks in my car, floor it a couple times in 4th gear, doesn't take long to eat a dime. I've even wasted 1/4 tank in the 6.5 miles from my house to my office just to see how fast I could do it.

Turbo cars get better mileage/rwhp thanks to using free power to turn the compressor, blowers use crankshaft power to turn the compressor and turn in lower rwhp per unit fuel burned but they get about the same mileage if you stay off the right pedal.

I think you have a fuel leak or something how the hell do you only get 8-11 mpg in the city. Do you drive around in first gear?

Youve got to be kidding right?? Theres no way a terminator gets as good MPG as a GT. I drove an 03 for a week and it about put me in the poorhouse! I was running through almost $20 bucks a day driving that supercharged beast!

Well, I kinda do drive around in first and 2nd gear and I floor it off every stop and keep it floored until the next light. Why stick around with the moron patrol that is everyone on the road when i have the traction and power to be way way way out in front of 90% of them, safe and secure in my own time zone of pleasantly empty road.

Assuming all else is equal, aka cars make the same power and have the same driving conditions etc etc

a positive displacement supercharger aka Roots/twin scew (KB/eaton) will hurt your gas milage.

A Turbocharger or a centrifugal supercharger will increase your gas milage.
