ok so heres an idea i came up with in a dream, i doubt its possible but worth a shot..i see all these cold air intakes people try to make, but shit, what if i bought a ebay cheapo FMIC and piping, and somehow hooked my MAS to the upperintercooler pipe, and just bolted on a K&N on the right side of the intercooler, where the other pipe would go back to the turbo i think, it would look sweet, confuse people and possible be a true cold air? as for water or things, i could cover it with like a splash sheild, just the idea of using a cheapie FMIC for an intake? crazy ? yes..will it work? maybe?:cool:
 
Well assuming this doesn't end up becoming restrictive with how much air can get in I don't see why this wouldn't work quite well actually. Sounds like a really good idea to me. I think I might try it myself...
 
Haha,I've thought about that a few times...mostly when I took the lower part of my cold air intake off and noticed a slight loss in throtle response.I was thinking more along the lines of the stock sidemount though to keep all the shit on one side of the bay but you could also just run a tube back to that side...theres surely no turbo to interfere with where the piping would go,haha.

I have access to tons of FMIC's from a Volvo shop for free and am good at fabrication so it would cost me nothing to try,I have most of the tubing and can hack some intercooler piping off a doner car if I need to.

This is how people come up with things that may make a difference...you never know until you try.

I have another N/T that I will turbo so you can save that response.
 
I would think that it is going to make you lag more because you are having to fill that entire intercooler up with air that is being sucked from the filter, into the cooler, up the piping and then into the intake mani. Think about this, the more you add, the more volume, the longer it takes to build pressure up (or vaccum) so the more lag you get. It would probably work fine, but the performance i would think would drop because of the increased lag.
 
well, i see lots of mixed ideas, and i dont know anything about intercoolers, ive never dealt with them, it just seems like a good idea. i may do it , i may not. also, to whoever said to buy a turbo car, its a lot easier said than done. all you guys live in sweet places where peolpe dont suck, i live in ohio, in an old people town, surrounded by nothing. i havent found a tsi/gst/gsx/rs within 50 miles.:)
 
50 miles? that ain ISHT! I drove 50 miles from my parents house to see my 1g,then 50 miles back to get the money,then 50 miles back to the car,then 120 miles home. I wanted it that bad. Not only that,it was my wifes tax return money,so i had to convince her to get it for me. If it's too easy,you'll never apreciate it. Then i got lucky and stumbled upon the gvr4 in front of my parents house while visiting,for 1500 bucks:sneaky: :sneaky: :sneaky:. It's not that hard to find a turbo dizzem,specially if your not after an awd. You already got intake and exhaust right?I would just buy some rims for it to hold me off.Maybe a header and underdrive pulley?keep it for a DD,and get the turbo dsm.whatever you decide to do good luck.
 
Intercoolers are meant to cool hot air from turbos... The air your suckin in is not that hot, so its not gonna do much except be a big restriction... If this was like the best idea dont u think a couple car companies would be on it?:notgood: think about it

Ya this brings up a good point. An intercooler cools hot air from a turbo. If you are sucking in air from the outside and attempting to cool it with more air from the outside it isn't going to decrease the temperature anymore than it already is when it gets sucked in. Your best bet is to try and fabricate a ram air if you want to make your MAF more efficient.
 
Like the last 2 have said. A turbo heats air, which gives a need to cool it. A cold air intake is taking air at ambient temperature. An intercooler cools to ambient temperature, thus you get no temperature loss. If the intercooler were even somewhat inside the engine bay it would likely work to heat up the intake air as it would be soaking up heat from the engine.

How about just wrapping your intake tube properly so the air stays nice and cool all the way in?
 
As far as "if it was such a good idea ,why wouldn't car companies do it?" We all know theres plenty of great ideas that production car companies could give a shit less about...it would cost them more money than the gain is worth.

But..if you have your filter in the bay,high up,cause you're scared of hydrolocking the car again....this is a great isea to cool it back down to ambient temp.

Lag? What do you think is in the intercooler? Air. Nothing is going to "lag" , this is not a turbo so lets use a more relative term like restriction.

Now...as long as you do not Restrict airflow by using an intercooler of the wrong size,(which almost seems impossible,if it works for a turbo car it will flow enough for a NA simply pulling vacuum),there is no way this can hurt the car's performance,only help.

I notice a huge difference in the relationship between filter placement/intake air temp,and throttle response when its moved in my car.If I could have the same performance with my airfilter in a safe location as I do with it behind the air dam....I would love that.Imagine the power increase on a cold day.

Do it man, but only if you can do it very cheap...its not gonna be worth it to you if you spend alot of money...more of the fun would be the work itself and trying something that nobody else has for me.
 
Actually it is lag. If you do not get full power from the push of the pedal right away then that is lag no matter what way you look at it. When you hook up cold air intake, you loose launching speed. This is because you have to wait for that initial air from the filter (not the cooler) that is being brought in quickly to adjust with the fuel flow to reach the manifold. All the air that is in the intercooler to begin with is moving at idle speed so that air is not moving nearly fast enough to keep up with the added fuel from going WOT. Now because you are at WOT and are waiting on air, you would see a spike in the air/fuel (if a gauge is installed) in that split second while you are waiting for the air to reach the manifold. The air now has to come in at idle speed, then at the hit of throttle has to speed up and reach the manifold, and this volume in between is bigger, causing slower reaction times, but CIA will give you ambient air and faster acceleration. Why would you not call that lag??? are you not lagging while you are waiting for full power to reach the car? If you could explain why that is not lag, maybe i am misunderstanding what you are trying to say.

Most of this guys info is false. Don't even bother trying this as it will not help you in the slightest way.:toobad:
 
I hope you got outta bed and you were already wearing your flame suit.

This is not true,at least not on the 2 I've owned.

If you want to continue to try to tell me what I've experinced and argue about physics I'll PM you my phone #.:D

So even though you are waiting longer for the pressure to build (suction) on the intake tube, in order to get the intake needed for the added fuel you still had the same amount of response as a ram air? I dont really see how that is possible?
 
Wasn't singling you out in that last post...I'll PM it to anyone.

I had a longer intake track than stock,yes,but the diameter of the tubing and smoothness on the inside,as well as an increased flow filter lets in plenty of air when you snap open the throttle.If a cold air intake didn't increase throttle response by allowing more air than there wouldn't be much of a point....its the lowereing of intake temps AND increased flow rate that makes it work.

If there is nothing restricting air coming into the system,what would hold the air momentarily to make it lag? As soon as you snap open that throttle plate.All of the air will move at that speed unles you have a mile of tubing.As long as the intercooler can flow what the intake can I see no way that this will starve,hurt,or lag the airflow into the engine.

pr0...where is this false info at? I've simply stated my experience with airflow on a NA motor.
 
well if you put an intercooler on and got a Co2 Sprayer on it. then you would have some sort of gains at the track.

also N20 is a very effective way of decreasing the intake temp when it is injected into the intake pipes. :p
