hey guys.....im wanting to win a little competion...its not a race....it a fuel efficency competition.....im trying to prove my v-tec e has better efficency than a prius......ive checked into hypermilling and got ALOT OF INSIGHT...but that is all based on techniques.......im looking to improve the effecency of the engine now....ive ordered a cold air intake a exhaust sys irridium spark plugs.... lighter rims and carbon fiber hood......stilL looking for a chip......but i have a NUTTY IDEA........if nitrous is a chemical catalyst.......what if i made a custom slow leak nitrous system?? do u guys think it would improve milage since im NOT USING IT for acceleration.....just to drop the intake temps......or maybe a water injection sys?? any ideas??

Well the entire point of you trying to improve gas millage would translate into one thing and that is saving money at the pump.

With the money you spend on all those parts you probably could have paid for your gas for 2-3 years solid.

Also I would not use your car as test bed for you mad scientist experiments something is bound to go wrong.

I don't think you are going to come out with some new revolutionary idea so I would just wait a few more years and trade your car for some of the new fuel efficient cars that they are producing.

well murdock....this isnt about saving money.....it about efficency.......i know that additionaly translates into saving money.......but im not translating anything here........i just love efficency.....plain and simple...it gives me a hard on....i love improving on things that are already great....cause there is always bound to be better ways.....i plan on keeping this car for more than 2-3 years solid im not coming out with any revolutionary ideas im just using old ideas in new ways.........and i dont plan on becoming a indentured servant to my car company again untill cars fly

Well if you really want to win, its going to have to be done with weight. I suggest that you should try to remove components that are going to weigh you down, such as a whole sound system, hell take out the head unit, as well as well as the wiring, the center console, speakers, and other panels. Back seats should go, the spare, any thing in the trunk, and even brackets.


This is where tape comes handy to hold all those things down, and if you know a machinist, make some aluminum replacements.

Good luck with all of that

mmm......great stuff tomcisneros.......weight is def an enemy......but seeing as how my buddy's prius has a/c a stereo and room for five.......i gotta be fair and retain all that dead weight.......we both have everything dead stock...but i have a feeling i will be able to find more aftermarket motor goodies for us honda guys than prius owners............for now!......anyway....any thoughts on how to massage the motor better/diffrently?? ......any opinions/ideas on water injection.......or nitrous?........heard turbo's add efficency .....just gotta keep the foot out of it!

With a vafc2 you could tune your air/fuel perfectly and tune vtec. (making your engine operate more efficiently then when it came off the lot)

I think I get better mileage with my vafc tuned but, I’V never tested it...

Funny idea though.

I love a good debate between Honda and Toyota.

Do underdrive pulleys, like AEM Power Pulleys. They will slow down the power steering pump and your alternator which = more efficient. Definitely lose as much weight as possible. If your driving an automatic just give up the bet now. If you have a manual shift at like 1500 - 2000 rpms everytime and run in top gear as much as possible. Never run A/C or defroster/defogger. Lose the spare tire as a weight saver, and everything not bolted down for that matter. Don't drive with the windows down cause it creates more drag than windows up, if u want air use the vent. Keep the car in neutral when coasting to stoplights. Always brake gradually and gently, anytime your using your brakes your wasting energy (which is your huge disadvantage to the Prius because it has regenerative braking). On the freeway never go faster than 55 mph, above 55 mph the extra engine rpm and drag drastically reduces fuel economy. Best I have ever gotten with my civic is 44mpg, which was tough, so good luck. Unless driven in a retarded manner the Prius will destroy you in a fuel economy challenge.

OK.....in order....02BLKCIVIC ....thanx.....ive never heard of that product and im looking at what it does and it seems like it EXACTLY what i was wanting........D17sRuNtunable ..kiss my ***! not all honda's are about being fast and furious.....wheelspinLX.....never thought of underdrive pulleys.....but i like em!...it def will improve overall mill efficency..i def keep my rpms to under 2500 to take full advantage of my fake v-tec......or also called v-tec e....it will only open 1 intake valve if i keep it under 2500 rpm....im stuck with the spare...cause prius got 1 too...i never run the ac.....but i gots to rolls my's windows cause its just too damn hot in texas!!!....everything else you said is straight out of the hypermillers bible!!

no takers on the water injection or nitrous?

 
Rep Power: 238

Water injection or nitrous would just add more weight than they would be worth.
This whole idea is pretty stupid. Unless the Prius driver is a dumbass you wont be able to beat it as far as fuel economy is concerned. Especially since you tool around with windows down and you can't gain any extra weight advantage.

 
Rep Power: 315

No not going to get you the results you want.

Weight is your biggest enemy hear. That’s your only chance to get more MPG's

Is this topic for realz?

 
Rep Power: 238

You got to understand the function of water injection and nitrous. Nitrous is supposed to increase oxygen so that you can add more fuel creating more power, you dont want to add fuel. Nitrous and water injection also reduce intake tempuratures and that allows you to put more fuel in because colder air is more dense = more oxygen allowing more fuel = more power. In any case you want to put in as little fuel as necessary to get you X miles.

And unfortunately it appears this is for realz.

hey eazy cheesy calm down with the language son... shut up and take a seat. we float in the same boat...im not fast n furious either, im actually slow and...a pretty mellow guy on my good days. your little theory on water injection and nitrous is way out of ur league. u dont seem to understand what your talking about. kinda liek what wheelspin said, nitrous is kind of like an alternative fuel in a small bottle. when u dump it, ur going to need more fuel to compensate for the ever dropping temperatures. without the extra fuel, the nitrous wont even work properly and ud run the risk of breaking something. water injection is almost the same concept but alot less riskier... regardless it demands more fuel in the long run. keep it out of ur head and go hug a tree. im not trying to shut u down that bad but...u simply cannot win against a hybrid...well ...maybe if u ....no..nah nvm... look how about u try with all the advice everyone has given you and let us know how it works out ok??

so what makes a 2932 lb hybrid car that much better? its mostly about the driver it seems...http://www.motherjones.com/news/feat...permilers.html ..btw..water injection is NOT a theory at all.....look it up....there are kits for sale....even for your untunable attitude.....

Listen Man, What makes a 2932lb hybrid car better than ur civic is the fact that its running on electricity not Fuel. Your comparing a 2932 lb car for FUEL MILEAGE comparision not PERFORMANCE arite !!! So Just do us a favour, Like the guys above already said, Go ahead try all ur theories, Weight reduction, Intake, Injectors, Water kit, Nitrous and driving under 2500rpm ...

BTW .. please DONT SMOKE N DRIVE !!! or shud i say Smoke n FLY !!!

you could run using a tank of small plane fuel. expensive, but it will give you quite a bit better mileage. also, in order do drop intake temperature, you would have to drop a lot of nos. just dribbling it out won't do that. you could get an intercooler though.

mani im not quite understanding you.......you are saying exactly what im saying.....of course im not compaing a civic to a hybrid by preformance....that just repeats what i was saying......maybe ur having some problems understanding this cause you smoke weed.........cut back man..........i think mneuls understands what im trying to get at though........i like the intercooler idea...it is getting the colder denser air without the gas robbing power surge of my foot on the turbo.......dont they also make a intercooler that can be rapidly cooled using nitrous?....it obviously will have to be a blend of engine efficency upgrades and driving techniques to beat a hybrid...hell if that dude can get...59 mpg in a damn plain jane accord....then sheet! a civic shoould at least be able to beat that!! letalone any upgrades!

Okay your getting annoying now



Now let me school you for a second. Colder air is more dense, meaning there is more oxygen in it. Your car picks up that increase of oxygen and tells itself "Hey more oxygen means I can burn MORE fuel" and more fuel is introduced to keep your air fuel ratio from going lean. You DONT want to put more fuel in, so it doesnt matter. You want to go as many miles as you can on as little fuel as possible. I hope you understand now. If you don't believe me then knock yourself out, but considering the amount of knowledge your displaying I don't think you have a chance.

P.S. Your use of periods makes me ****ing furious.

I read in a magazine article, I believe it was popular science that if you were to remove all those heavy batteries and the electric motor out of the Toyota Prius it would actually get better MPG but then they could not badge it as a "Hybrid" and that Toyota concluded that it would not sell as well.

My point is, Weight reduction is a major player in MPG

just make sure you both run on the highway. That will cut his mileage by a lot.

 
Rep Power: 261

thanks wheelspin u beat me to it....nitrous cools ur engine because of ALOT of THICKER, DENSER AIR. COMPUTER SAYS MORE AIR=MORE FUEL, if not you get a lean mixture, wich is bad. u wont get better milage. and when u say ur going to use 1/6 of a performance application? what is that going to do... that wouldnt do anything with gas milage or making ur intake temp. drop.. and when do u plan to use that amount.....ive never had nitrous in my car but i think it works by the push of a button...what? every half n hour ur going to push it for a fourth of a second??? we dont get it. the nitrous idea wont work as well as u plan it to. for what your putting into it and the hopes u have for it, you will be dissapointed with the results. and another thing...an intercooler? i think u need a turbo for one of those. turbos are the things that put ALOT of air into ur engine......um...MORE FUEL. they have those iintercooler looking intake things but i dont they make them for civics...well not that ive seen.

you might want to reasearch this, but i have heard that adding small amounts of Pure acetone to your fuel will increase your mileage by 20%+

what you need to do is set up this "race" to your advantage. and you should be able to win easily without modding anything. on the highway, the Prius's mileage drops from 60+ mpg to just under 50mpg, it makes his electric motor + batteries pretty much useless and dead weight. if you take out everything in your car that you can (your head rest, glove box, passenger seat, back seats, everything in the trunk.) also you could wash it really good under the front and rear bumpers, to get rid of the extra weight of dirt that sits in these areas. this alone should increase your mileage to about 45mpg. if you draft behind your buddy all the way, and use premium gas with octane booster, you should have no problem.
