name me all the components that saves gas(more mpg)

LeeMaster · 10-24-2009, 04:30 PM

i know only a few of these..

intake
air filter
i also heard Hondata reflash saves gas??
turbo saves gas if you dont floor it??

what else..?

if you're complaining about gas mileage on the tsx. mmmm you should probably get a different car lol. tsx already gets pretty good gas mileage. but another thing to remember is.... most mods dont go well with fuel efficiency. a more restrictive exhaust may help though. and if you downgrade your cat to an 04/05.

make sure your tire pressure is on point every month or two.
make sure your car's wheels are aligned/balanced.
when on local roads have the windows open if it's hot
when on highway use the ac to decrease wind resistance.
and dont high rev.
those are really the only tips i could think of. other than keeping your car stock lol

nice ones, oh and im not complaining about the gas mileage, i just want to expand my knowledge on the TSX. or any car in general.

Biggest myth in auto world. Using AC is substantially more hurtful to fuel economy than rolling with the windows down at highway speed. drop in aerodynamic efficiency with the windows down will be only a couple of percent. running the ac will affect fuel economy by up to 10-15%.

also going with a more restrictive exhaust would hurt fuel economy. more efficiently an engine can pump air, better fuel economy can be achieved. Try breathing in and out with a straw, you will end up working harder. Same principle with an engine. Engine is merely a heat pump, so if you restrict its air flow whether its intake side, or exhaust side, it will end up being a less efficient unit so in order to produce the same power that a less restricted engine makes, it will burn more fuel doing it.

Just use common sense when driving. No crazy lead foot driving, no sudden stops, hard turns, stay within the speed limit, make sure your tires are inflated to correct pressure, make sure car is well maintained, and most importantly use your head

i2ide · 10-24-2009, 06:11 PM

idk bout the exhaust though.
if that concept was true. a straight pipe exhaust from the header would be optimal. but it isnt. ive seen it on a lot of cars.

ThirdLane · 10-24-2009, 06:17 PM

Exhaust systems serves two purposes in a vehicle: to muffle exhaust resonance of an engine and two create some back pressure. NA engines need some back pressure in order for it to be efficient. If you open up an exhaust all the way, you lose efficiency but if you restrict it, you lose efficiency even more.

When on highway use the ac to decrease wind resistance.

how could this work?

myth was that rolling on the highway with the windows down would increase aero drag because of the open windows so some thought closing the windows and running the ac would be better for fuel efficiency sake. But sacrifice in aero efficiency with the windows down is next to nothing compared to running with the ac. Its been proven that running with the ac on(on a traditional belt driven compressor system) with affect fuel economy by up to 10-15%. Even all electric system ac systems like on the Prius will affect fuel economy by 5 to maybe 10%.

mclovintsx · 10-24-2009, 07:59 PM

Well on highways, I roll the windows up and use the AC but I only set it at the lowest point, so 1. or you can open the moonroof from the back where it tilts up, and open the air vents so it'll be like an AC.

mclovintsx · 10-24-2009, 08:00 PM

oh you can also lose weight.

Less weight, less gas.

CraZie · 10-24-2009, 08:28 PM

+1 on weight reduction. haha

The exhaust restriction is the worst idea ever. Restriction creates pumping losses, this is bad, and hurts the motors efficiency.

If you want better gas mileage, I would say airflow restrictions, remove them, leave the cat, or at least a high flow REAL cat on... and less weight. One thing that no one ever brings up is longer gears. The tsx tranny has super short gears. Older honda's I've had had substantially longer gears. After I did a ported head, with opened intake manifold, bigger throttle, decked head, and header of course i/h/e (also had fidanza flywheel) I took my 28~29 mpg 98 accord to roughly 34 mpg on the highway. I could cruise at 80 miles an hour in 5th gear at less than 3k rpms... On my tsx to do 60 miles an hour, I am just at 3k rpms...

If you had a taller final drive, or a taller 6th gear, where the engine could turn significantly slower at highway speed, you would get better mileage. However, seems that this is not a option anyone even entertains here...

That's how GM gets the corvette to get the mileage it does... it's 6th gear is like a 2:1 it's rediculous and the motor turns at like 1500 or so 65. (haven't driven the car, so I cannot say, but you can do the math for the tranny with their information on their web site.)

I also think for boosted apps a taller gear option would be great, because accelerating under boost with long gears is alot of fun, and yields good mileage, relatively speaking.

Anyway, since I am sure my words probably aren't taken too seriously... I did some research for you to read on your own...
