Mods that increase fuel efficiency

Alright, there are several discussions that intakes increase your mpg's. I'm getting an intake whether they do or not. But what other parts could you put on your car other than intakes that increase fuel efficiency? (Other than carbon fiber parts which make your car lighter).

Anything to make it breathe easier i presume.So I think i/h/e would help out.

hot air intake.

installing a raw egg between your shoe and the accelerator pedal LOL

It seems like most air-flow-increasing mods help significantly for highway mpg but significantly hurt in-city mpg.

I don't really know why, but that seems to be the deal. My eclipse used to never get over 27 mpg on the highway until I did I/H/E, now I get 32mpg on the highway but I usually get 18-20 in-city now compared to 23-24 in-city.

So I guess it depends on how you drive.

so far the only change listed and verified to do what you asked for

I am no expert, but here is what I picked up from different places (some may work better than others or not at all).

Tires - Skinnier tires for less rolling resistance and improved aerodynamics. Also, inflate tires a little more.

Lowering the car - less air drag (may also make the car look better).

Scangauge - Gives data, but more importantly, MOTIVATION to drive conservatively.

There are also crazier mods to be done...

Haha. Must add rubber mats -- just in case.

In reality.. reducing weight and increasing aerodynamics are the best ways most obvious ways to increase efficiency.

i agree with lowering and increasing aerodynamics, but that only goes to some extent.

WE ARE ALL BASICALLY DRIVING THE SAME CAR. IT'S THE DRIVER THAT DICTATES THE MILEAGE!

Yep. Adjust the nut between the steering wheel and the driver's seat.

i have this new produced item called an IPR which is a japanese product and is used one this months issue on D-sport! result vary but from the customers i've had they have been really happy with the results. PM me for more info

what is a hot air intake?

solbrothers · #15 (**permalink**) 04-05-2008, 05:09 PM

iirc, basically an intake that is near something hot in the enginebay? idk for sure though.

i know my escort had this. it was a pipe that went from the exhaust manifold cover to the intake. when the car wasn't warmed up, this valve was open, lettiing the hot air it. after the car was warmed up, it closed.

How bout a spoiler? A while ago I posted something about the aerocivic. A big downward sloping (and somewhat coned shaped) spoiler should decrease aero drag.

That's what I call short ram intake

And Solbrothers, that valve to help your escort heat up was probably emissions related and not fuel efficiency

Sorry to burst your bubble. It's pretty much an early prototype to nowadays secondary air pumps.

yessir. it WAS for emissions, but still was sort of a hot air intake LOL. i took it off as i "thought" it was hurting performance, and sure enough, it failed smog

I can imagine weight reduction on the car and driver ( I need to lose some lbs

).

Turbo charging will actually increase mpg. It atomizes the fuel, brings the air to a static temperature, and increases the airflow.

.....now driving like a normal human in a turbocharged vehicle is another story. (individual results may vary)
