Air Injection.....

[skoodles]

there was a local guy that did that on an eclipse. had a tank mounted in the trunk. i road in it and all it did was bog the motor down. he swore up and down it makes a difference but all it really did was bog it down and change the pitch of the motor.

LOL...Yea man, I think of things all the time that should just be kept in my head. GSROWNSU is right, your wasting time. It's not going to burn anything up and your not going to gain any power. Your car is already sucking in as much air as possible that your tb, manifold, and intake ports will pretty much allow. You putting air in there is just going to disrupt everything.

i can't believe this has even been a topic of conversation. So your going to put "5psi" into your intake? Have you ever felt 5 psi from a air tank before? It's absolutely nothing. 5psi from an air tank is not even close to the same as 5psi from a turbo lol. even if you put 90 psi from this air tank into your "short ram intake" where is the air going to go? Some will flow into the engine while disrupting turbulence from the engine breathing in air while the rest will just exit the filter of the intake lol. Second of all doing anything pre-map sensor like this while keeping everything stock really does nothing. Even if it was enough to make the map sensor compensate it will only compensate so much....but 5psi of air pressure from a tank will do NOTHING except rob you of power and add weight to your car. Buy one of those E-Superchargers off ebay for 70 bucks, you might have more luck than this...but not much... ....fail....:kickass:


p.s. this thread should be locked and burned in hell forever for how ridiculous it is.

Im with this guy %110. This topic is far fetched even for me. This would work nothing like a turbocharger. the whole reason a turbo is able to build boost is because it is a closed circuit of air, meaning there arent any leaks. What happens when you have a boost leak? your psi drops. So assuming this tank of air would be the turbo, and a line running to the intake pipe injecting however much air you choose, its not gonna build pressure, if the air completlyfills the IM,TB and intake pipe, its all just gonna blow out through the filter. To me i think this would be like a ram air setup and only good for like 1-2hp. But its not gonna build positive pressure in the intake mani.

for the record im not trying to shoot the guy down or ruin his confidence. But it seems a little off that alot of people on here think it would actually build pressure.

Well, like I said, I never really thought it was going to work in the first place, but my bro was convinced on it gaining hella power. Whether it works or not, what the hell; it's nice to have an extra air tank laying around in the garage anyway. :lol: The only thing expensive in doing the setup was the 5lb bottle (tank) from Harbor Freight for $40. The fittings were like $1 each, and the APR was $7. And the air hose was like $7 for a 15' roll.

Well, here's something........... I don't see how the air would come back out the filter; the airflow is going towards the TB and IM and head, so shooting air in the same direction would just increase the flow, I don't see how it just turns around and goes the wrong way. Even if it did turn around, there's more air coming into the intake system; which is flowing at a higher velocity, which would just hit the oncoming air and then just continue on it's way into the engine.

edit- I suppose we could bust out the die grinder and port the IM to help get more of the air in...

I thank everyone for not flaming the snot out of me yet for this ridiculous idea, but in my mind, it seems like it SHOULD work. Not done with it yet to see if it DOES work, but theoretically, it SHOULD. He wanted to test it out to see if it works, so he knows whether to spray it or not when we hit the track again this weekend. :thumbs up

Like I said, your engine is already sucking in as much air as it pretty much can. Your trying to force more air in a place where it can't really go anymore. So therefore since your already ingesting as much air as you can through your intake valves the access air is going to try and escape. therefore it will revert back towards the next possible escape route, being the throttle body, and will push against the incoming air reducing it's velocity. Also please don't try to hog out your intake ports, thats not going to help.

I'm not trying to spawn a e-fight or anything, but I just can't get past this. If the engine is already sucking in as much air as it can, why do you gain power with a turbo? A turbo does the same exact thing, it's shooting in air too, so why don't the turbo experience the same problem? Meh, I suppose since a turbo's air doesn't have anywhere it can backtrack too, since the compressor is always shoving more and more air.

Ugh, i'm spawning a headache that's for sure. :lol: Too confusing this subject. Well, like I said, if it works, cool. if it doesn't, meh what the hell, it was worth a try. :thumbs up

If you do that, someone should hit you...:wak:

Your increasing airflow volume (supposedly), but your destroying the flow quality. Every part of the engine before the combustion chamber is specifically sized and designed, through millions of dollars of R&D by the manufacturer, to maximize airflow volume, airflow speed and airflow quality into the combustion chamber. The intake arm, throttle body, IM intake port, IM plenum, IM runners, intake ports and the valves themselves - all diameters and legnths of these parts play a role in drawing air into the engine. This device you want to install will wreck the flow quality. The intake maniflod's on Integra's are "acoustiically tuned" to assist airflow entering the intake ports; this IM design requires quality airflow to work properly, that thing will kill the quality.
You'd be better off just getting an aftermarket intake with a quality high flow air filter like a K&N.

That's a nice piece of information. Thanks. What if we shoot it further away from the MAP sensor on the intake tube, so it fills up the intake pipe, and flows like normal quality, but faster?

Well, it's already got an intake on it. A custom 3" intake. It's funny, the intake is actually supposed to be a side-exit exhaust for a Chevy pickup, but it fit perfectly, and got it for free. So I slapped on a PepBoy's Spectre filter and called it a day.

My god, did anyone take any science type classes. Your always going to have the same amount of air in your intake, tb, plenum, etc. This air is not compressed, therefore it is always equal. You can't put more air in there because your not compressing it. Just because you have a compressor shooting air doesn't mean you have compressed air coming out. Turbo's and superchargers compress air. If you want to know how google it.
