Hrm, not sure about that one, more air = more fuel, especially with a MAF setup. And as far as more power per liter equalling better MPG, look at an S2000, does it have a ton better gas milage than a 2.0 Acura RSX?

colder air is denser, meaning more air per cubic inch. many vehicles pull the air from the fenderwell off of a 900°F brake rotor/caliper. it can get better air than that.
more power per liter i meant liter as a metric measurement of fluid like gallon.

Yeah, more dense air = more fuel required to remain at a stoic. A/F ratio ... unless you want to run lean all the time 😉 You'll end up using more fuel if the engine compensates for the increased flow of air.

thats what removing the screen does, it tricks the sensors. but i dont recommend you just try it without researching your make and model and what others have done.

What do you mean by "that's what removing the screen does"? Makes the engine computer compensate for the increased air flow? If so, that would mean pumping more fuel into the motor 😛

No it makes the engine think that its getting less air then what it actually is.

the maf screen slows the air down and makes it follow a measurable flat line path.
you remove it and the sensors still measure air but they cant measure it all.

on some engines this causes a lean running condition which can trip error codes in the computer.
so be sure you research your exact motor before modifying it.

Say you have a small car with a V6 engine, and the transmission has regular "Drive" and "OverDrive". Which saves more gas in what circumstances?

Good. My earlier reply was meant to be a warning just like that. I didn't want random people out there to just go and start removing their mass airflow sensors and then wonder why their cars run like crap/not at all.

I hear that on a manual gear car, its advantageous to the fuel economy to give about 75% gas in each gear and shift up quickly. Of course, you can't do this on an automatic, since when you push the gas 75% it would shift down and rev up on you.

my dad does that, though he does it to an extreme that's annoying...he'll be going 35 in 6th gear with the engine turning at like 1100rpm :disgust: (this is a sentra we're talking about) and it lugs the engine

Keep your car waxed. Less wind drag on the skin.

i hope you're joking... if not lol @ u :laugh:

He's probably using more gas doing that than he would if he drove like a normal person.

and if you need to save brakes, find a nice toyota or volvo to run into..

and no, telephone polls and deer dont work.

Or double de-clutch downshift, but your theory is intriguing and I wish to subscribe to your newsletter.
