Front Mounted Intercooler = More MPG?

[Nexagen]

Considering that you are not running Forced Induction and you are using it to cool air in a CAI (Cold Air Intake) to make the air inside the intake colder... and you are running an aftermarket exhaust and headers...

Would that give more MPG?

[beef_bourito]

you're trying to cool ambient temperature air with ambient temperature air, it won't do anything. you're sucking air into the intake that's the same temp (or very close to the same temp) as the air you're using to cool it so you won't get much cooling. the only thing it'll do is provide a restriction in the intake and will actually decrease your gas mileage and power.

no. it's more restriction for the air. it will have a negative effect.

as a moderator you should know to read previous posts. if you had done that you would have seen that i already gave that exact answer. common, try harder.

don't make me ban you.

lol about the banning thing...

I don't think you can exactly vary your MPG by changing the air intake. Cars are tuned to vary fuel mixture to get proper exhaust readings as well as read how much air is being put into the engine. Suppose that your air is more dense and you have more oxygen within a smaller volume. Then after it passes through your engine, your O2 sensors will read higher O2 levels than usual in the exhaust. And the fuel ratio will be adjusted accordingly. Thus, you get more power, but I'm sure that would decrease MPG if anything.

Correct me if i'm wrong...Even if I don't show it, I do like learning from people on this forum :P

if you remove some restrictions in the intake by installing a new intake you might pick up a few mpg but most modern intakes are pretty good so it usually won't be much.

The best thing to do short of FI is to have a ram air setup. Which many companies do usually on higher level cars. But even my dads Hyundai Sonata has a small air inlet right under the hood.

ram-air or col-air intake will help. intercooling a non F/I engine is like walking in running shoes. you'd think it would help, but it doesn't.

[beef_bourito]

also, ram air on most cars won't really do much. you have to go to very high speeds to get any kind of performance out of them, they're mostly good for sucking cold air from outside rather than getting it from inside the engine compartment, and that's only a small improvement.
