First of all, thanks to all the folks who make this forum great!

I am a new member; I just ordered a Black GT/CS Coupe with a manual transmission. It should be here in June - I can't wait!

My Mustang is destined to be a daily driver (I have two other cars to wrench on, so I have plenty to keep me busy). As such, it will have to serve as reliable, daily transportation.

Since I like performance, I want to do what I can to increase performance WITHOUT SACRIFICING FUEL ECONOMY. With gas currently over $3.00 per gallon, I hope folks find this thread worthy. Once I get my Mustang, I'd like to run some baseline tests of fuel usage, and then makes some mods and see what happens.

To start off, I'd think that changing the air filter is a win-win situation from a HP/MPG standpoint. Further, changing to headers and larger exhaust may also do the same. Do forum members have any experience with these, or other mods, and the fuel usage after the mods?

Thanks!

Drop in does nothing. Cold Air Intake(CAI) and a re-tune does wonders for the vehicles. About $600 ish with the CAI and tune, but gets about 30hp and better mileage and throttle response. They are very sensitive so the tune is required with a CAI. Search for the dozens of CAI threads for tons of info... Exhaust modifications also enhance fuel mileage and power, but just changing the mufflers is for sound only for the most part.

 

The issue you'll find with doing mods is that some could maybe help economy (like a free flowing quality cold air kit), but the downside is you'll usually be putting your foot into it more often to enjoy the power/sound.

In most cases your best way to minimize fuel consumption is to moderate your right foot. Enjoy your new stang though, and welcome to the site!

 

You won't notice much fuel economy gain, in theory your engine will be more efficient (getting more air in the motor, and flowing it out of the motor more easily) but like Cowtown said, it's all about your feet.

I can get 14mpg in town, or I can get 8mpg in town, just depends on how I drive. My car has modifications that hurt mpg pretty bad though, you'll most likely get much more than 14, I used to get 17+ in town and 27 on the freeway, now I get more around 13 in town and 23 on the freeway with steep gears and a supercharger.

 

I find that in both of my cars, turning the vehicle's computer to estimate the fuel economy keeps me from wasting fuel

 

You are not going to increase your Fuel Mileage by doing any performance type mods. The two do not correlate together. People ask this over and over again and to increase power you need more fuel and air therefore the fuel consumption is greater.
