does anyone know how much gaqs mileage you are going to give up for horsepower. what are some performance upgrades that take the least amount of gas mileage from your car but you can still notice a performance difference?

There is no such ratio. My SRT-4 makes 452 hp, and get 35mpg highway. Many performace modifications improve mpg, but your driving style knocks it down.

 

Hmm. 452HP and 35MPG. I'll take two!

 

I'll second that

Hey Gary, wanna come over to my place this weekend? I've got some work you can do

 

A turbo benifits MPG quite a bit, if you are not using the turbo, you can run close to stock MPG. 35 MPG is pretty high on a stock neon though, that must be with the cruise on, lol

 

SRT's don't have cruise, that was just keeping my foot out of it.

 

I know they don't have cruise, I was just being sarcastic, 35MPG is a pretty good # though.
