EcoModding for Beginners: Getting great gas mileage.

[Volgrath]

I've been reading, I'm wondering. The main issue with the hot air intake or warm air intake is that it does lose air density. SO why can't someone put on a bigger throttle body and bigger aluminum tubing (aluminum so it can transfer heat better than plastic) so that it can get the same density as it was stock while getting the benefit of it being warm.

Well, the benefit of it being warm is that it is less dense, so that would cancel much of the benefit.

oky doky, thanks for the info!

Thanks for the mix of ideas. I like the way you give several options in each category as sometimes one idea in a category is not an option. Here in San Antonio, bicycles are just now being embraced by a small part of the population as a means to commute. Most drivers here just see bikes as a new "target". Most drivers here who run over bicyclists are not charged with a crime unless they are drunk. I sold my 96 Del Sol S Automatic and bought the same model with a 5-speed and increased my gas mileage from 32mpg mixed to 35mpg mixed with no mods.

I think that all of the people who discredit mods which increase horsepower are kind of missing the point. I changed my exhaust over to a stock style dual exhaust layout on my 95 Crown Vic, which was something like a 15 hp gain over single, and my average mpg went up by about 3. In my experience, if you have more power on tap but you drive exactly the same as before then you WILL increase mpg.

Also, I know how most people feel about doing so but I had a 1981 Chev Malibu and I cut out the catalytic converter (which wasn't plugged!) and I got an increase of about 4 mpg, not to mention how much peppier the car felt.
