There's no going around it, this will definitely make your gas mileage go down. Remember, increasing the gear ratio makes your engine rev higher compared to the revolutions of the rear wheels.

yes youre right but if i keep my revs down either way gas mileage wont change or it might even get better. as long as i keep RPMs low i should see decent gas mileage. by the way kenneth call my cell right now, im not doing anything.

glad to see you finally took my advice and got some 3.73's in that Stang! what took you so damn long???? LOL
and you won't see that much of a difference in gas mileage unless you just can't keep your foot out of the throttle 'cause it's so much more fun driving with them compared to the stock gears!

RE: 3.73's w00t bishes..
Yah Dbeck, but increasing the gear ratio, if you look at it logically, would decrease the distance covered for every revolution of the crank, so your engine is going faster while your car is moving less. Even if you go easy on the gas, that is still a fact, it might not make a huge difference if you lay off the gas, but your gas mileage will still go down, even if by a little, it'll never go up with a higher differential gear ratio.
Do you kind of understand how they work? The reason why your car goes faster with higher gears in the back is because you're allowing your engine to reach it's power band which is up at around 3500rpm before the energy is transfered to your wheels. So the gears intentionally let your engine rev higher while the actual wheels rev slower than before, but once you hit the higher revs there is enough torque and horsepower to get those wheels moving unlike before where your engine might get a bit bogged down on intial take-off. Either way, your gas mileage will never go up, but the amount it will go down I guess is relative to how much fun you have with it, lol.

RE: 3.73's w00t bishes..
your logic is correct but you are leaving out the part about how the lower gears will get the car moving easier and under light acceleration it will get into the higher tranny gears sooner where it uses less gas, so it all depends on how you drive it as to how much, if any, a mileage penalty there is to worry about. it is hard though not to jump on it from time to time just to let the engine rev, especially when you pull out to pass someone on a two lane road!
