Reversed Intake
Thursday, October 09, 2008 3:05 PM
I am working on taking the intake pipe from the throttle body to the black filter box, reversing it, so that the pipe goes down, and attaching the filter to it. It runs in front of the transmission. The filter is facing up.

I am spending zero dollars doing this. So I'll let you guys know how it feels and sounds when I am done.

I think it has something to do with the zero dollar effect. But I still ask y?

an AEM or even an EBay intake will do the samething

Yea you can really cheap out and use pvc pipe from a hardware store and get a decent filter.


oh yeah cars Especially with modding never have a zero dollar effect.

Research "Cold-Air Induction"... Fully. Building such a sytem will have greater effect than what you're planning.

Ok, so I couldnt get it to line up right. So I just left it where it normally sits, minus the giant black box. Works great. I can feel a better acceleration, and I noticed it when I was doing a full 10 mph faster when I was driving normally.

You'll have even better when you setup a Fresh-Air system! Trust me!

Yeah, dude, I have never heard of that term, and I cant find anything on it. So maybe you could stop being vague, and give me the skinny on wtf you are talking about.

Okay, I'm awake now...

The idea behind modifying the air-inlet system is to improve breathing. But just improving the ease of breathing isn't enough. We want to improve what the engine's breathing overall, force-inducted or naturally-aspirated.

Now, what you've made up to this point is a WAI (Warm-air induction) system. True, because you went with a filter with a larger area, it now breathes easier. And that's the only reason why it performs a lil' better. Not to mention the psych-factor that an unsilenced air-inlet tract has. But all that aside, truth is: You're not making that much more power. You're just breathing-in warm underhood air, which is great for mileage but not power. If it were breathing cool air from the outside the engine compartment, then you'd be making power. And the difference between the power made with a FAI & a WAI is night and day. Why? Simple: Every 10* cooler than underhood air an engine breathes, approximately 1hp is gained. Now, this don't seem like much... But when trying to gain more HP, every lil' bit helps. Especially on a small engine.

"But, how do we do it?", you ask. Simple: Collect air from the headwind the car sees as it rolls down the road, and direct it to the filter containment area (The box). This means the filter will need to be encapsulated (Contained, inside of) in a box that doesn't allow underhood air or heat to effect it. And tract(s) made of flexible corugated-tubing that lead from ports in the front-fascia or core support (Part that holds the radiator up) that face into the headwind & run to the filter-box will need to be employed.

Notice I say tract(s). This means that only one may be created if you like, as that one alone will surely help enough air reach the area of collection (filter-box) to help the engine breathe easier. That is, if you don't undersize it. How do you know what's big enough? Check the factory filter-box for a port in the side of it, that's on the opposite side of the filter from the tract that leads to the engine. Measure the size of it (It may be unround, so measure it width by height, multipy the two by each-other & again by Pi, and you'll have the area of the hole) and go no less than it in tubing diameter. And avoid sharp bends, as those hinder airflow.

A hood-scoop system may be employed, if you like. But remember: The more directly in the the air-stream of the headwind the collector opening is, the more effective it'll be at collecting air. And careful shaping of the tract for smoothest flow with restrictions should always be employed. I should mention at this point that the shorter the tract is from the collector-port, to the filter-box & then to the throttle-valve, the better it is for engine response to throttle changes.

I invite all that read this to consider this idea & attempt to employ it themselves on their vehicle in some way. You may even find (Like I have) that it effects the total throttle opening needed while cruising the highway (Re: Less), which in turn improves mileage, surprisingly. Thank-you for reading this far, and remember my signature:

Yeah, I kinda figured out what you were talking about this morning. I dont have a job right now, and I was bored. I think I am gonna leave it like this for now, until I get the money.

What you are talking about is those fake intercooler intakes right?

If you look where your stock intake starts. it starts right behind the headlamp. Its gotta be impossible to get a good size of air in there, and its not that far from the airbox either.

The stock airbox is a scam. The engine will heat it up, so as the air passes through it or waits in line to go through the filter, the air is being warmed up.

My engine can breathe easier. Thats enough reasoning for me to do it.

I am gonna go with the secret weapon intake when I get the money. Or maybe even add on to that to go down to the wheel well.

I cant really follow your "go beyond the bolt on" cause I am not gonna keep this car. Intake and exhaust maybe will be as far as I go. Unless I decide to keep this as a project car but then again its a cavi. so we'll see.

First off... No, I'm not talking about one of those fake intercooler intakes, unless you mean the screens some add that mount below the bumper in the chin-spoiler. If this is your response to hood-scoops, it's definately not what I mean. Look at older street-machines & Pro-series drag-cars & you'll see what I mean.

And as for the one that goes down into the fender, omit a fog-light (If you have them) on the fender it goes into & you'll see more air reach the filter than if was pulling it up from underneath. Also, if you go that route, put a splash-shield in place that seals-off the area where the filter is from everything but the fog-light port. This will create a collection area aroung the filter, allowing the air that comes in through the port to build-up a collection around the filter. This will result in the same effect as I've mentioned (Easier breathing & cooler air!).

yowsa

all you need to know dude is that you will not be improving your power even at all dramatically with an intake, unless its an intake that is driven off your belt drive and ends with the name upercharger



second you all need to know that it doesnt matter if you have a warm air intake, a cold air intake, or friggin ITBs with no filter, your engine naturally aspirated will only pull in and spit out a certain amount of air, therefore you make the same amount of power , relatively, whether your you have the stock system or a nice 200 dollar injen intake

if you want power go Forced induction, if its to expensive i would just leave the car as it was made in the factory

Im with you homeskillet. I was just bored, and it doesnt hurt the car at all. and it sounds louder.

I am either gonna keep this car, and supercharge it, or buy a cobalt ss. Im not sure yet, I am waiting to hear back about college funds. But like, I just dont like the interior AT ALL. its too damn bland, and all this navy blue color. I hate it. Plus my cavi is skin and bones, no options at all. but its cheaper to have. so thats the catch 22 im in right now.

Cobalt ss- more expensive, but nicer and all the work is done
Cavalier- cheaper, needs work and bland.

^Nice philosophy... You sound like all the other nay-sayers that have yet to even try to build a system like I described. Still, others have... And found it to beneficial to their engine's performance. This is just a method of trying to provide all (If not more) the cool air the engine can breathe. And make it easier for it to breathe, at that. Because truth is: Cooler air helps make more power.

And even if you do run a F/I system, you can't tell me (Or anyone who's built an engine) that you'd make the same power blown with warm air as you would cold. That's why intercoolers are usually intergrated with them. Doesn't it make sense that the air being pulled in be cool in the first place? Ask anyone who runs a turbo, and they'll tell you that they got more power when the ambient air was cooler than when it was warm, even with an intercooler.

Typical uneducated response. If forced induction were that readily available, everybody would have it.
So for those of us that are'nt made of money, we do the next best thing.

Here's some pictures to help you get some ideas of where you can run your piping and filter for some 'fresh air'.
Thanks for helping too Nickelin Dimer, some don't want to take the time to help and explain things like they should.

Here is where most put their filter for the best cool air they can get. It's covered enough so that water is never a problem unless you intentionally take it into puddles that come up over your rims.


Here is the piping from the throttlebody to the RKSPort cai intake tube which goes to the filter in the fender.


This should give you some ideas of how to integrate a premade, store bought intake or to make your own like I did years ago.
Good luck with it.

^Yes. Thank you, Misnblu. That's exactly what I'm talking about! Now, combine such a tract & filter placement with a hole, equal to or greater than the size of the tract's inside diameter, in the front facsia to that area & you'll have what I've been speaking of. You could even add an insert of screening to the hole to help keep large debris out, just as long as the mesh isn't too fine, or when it gets about so dirty it'll choke-up the flow of air & defeat the purpose of the system's design.

haha yes so uneducated!

so you didnt at all refute my claim yet IM the uneducated one?

sure you can put an itake on, and add one to five horsepower, if thats worth 30-200 dollars to you, then do it!

i used to have an intake on my car before i had the charger put on, and yeah it sounded nice

and i agree it does cool the air, but not much, you do understand that the stock system pulls air from the wheel well right, so just as cold as you will get with a aftermarket intake

people change NA intakes for less restriction, and not usually for air temperature

and the fact is that the colder the air, the denser the air, the more oxygen you can cram into the engine, and the bigger the explosion in the engine, more power to the wheels

what i am arguing is that its really not worth the money spent on an intake when the performance differences are so small
