do you guys think this is going to work?

Well theres 2 things that come to mind.
1. You have a S4, that air meter needs to be turned FLAT, level, not like it is.
2. I really would not bother, I believe here it was posted that your efficency when the hot turbo compresses air neglects the effects of a CAI.

so it won't work eh? damn that sucks. I'm going to try it a couple of times to see if anything happens as far as a noticeable h/p gain but I think you guys are right and it is just going to be compressed and hot anyways. However wouldn't it mean that if its cooler before the compression it would be cooler after the compression?

when I was doing the math for my friend's turbo projrct, I made a program that spit out the temperature of the compressed air after the turbo when given the air temp, boost pressure, engine rpm, ambient pressure, and a couple more factors I forget right now. IIRC, when the ambient temp was 70 (CAI) compared to ~150 (HAI) the compressed temps were about 20 degrees lower. not much, but every little bit helps.

Lives on the Forum
Honda Dude, that's not a ground on the boost/pressure sensor I see, is it???
If the AFM is fairly vertical (as opposed to horizontal, or "flat") it will work, but not very "efficiently". I don't know really how to explain "efficiently" other than that she seems to run differently, especially at idle. No hesitations on the bumps or loss of power or anything like that, just...different...Even the voltages were the same at the ECU while driving & romping...It may be all in my head, lol...I've ran with mine at a 90* a couple of times after installing the CAI. It fit a lot better that way, as it seems to be doing in your application... We had a civil discussion a while back on the forum about the pros and cons of mounting her at a 90*, and NZ finally changed my mind by saying something along the lines off, "No other manufacture or car has the door in the AFM hinged like that, they all have them swinging horizontally"...Since I respect NZ's advice immensely, I followed it. Fits like crap that way, though, lol...
At any other position or angle, the door will tend to bind up during travel. Don't take my word for it, pull yours off and play with it at a 45* angle and see for yourself...
Have fun

oh **** I didn't even see that anyone else wrote anything. Thanks guys! kks thanks for the info on that I wasn't sure it the temps would be the same or differnat after the compression of the air so maybe a cai would be good on a turbo??? I'm going to try it now Thanks again. LOL, wayne I figured one day you would see that ground and kick my *** for having it. The only reason that ground is still there is because everything is working perfectly and I don't want to screw anything up (knock on wood)lol. I may get ballsy and take it off one of these days. Thanks for you input on the afm!!! I know exactly what you mean by not working as efficiantly because when you open the afm flapper with your had while the car idles it doesn't do anything but bog the engine down so I'm guessing it does the same thing here but not to that digree. With my home made intake It's hard to fit it in a lot of differant ways so I'm kind of limmited to just a few wich narrows me to having to put the afm in the wrong way. however if you look at the "old school trust intercooler" thread you will see the afm with just a cone on it and I was able to turn it the correct way. Thanks again yall.

I want to revisit the coldness part... I agree with the AFM part... but if PV/T=PV/T then there's no way that the temperature can go up unless the pressure or volume go up... and since the volume of air is obviously not gonna change... then the temperature will go up an amount directly proportional to the amount of increase on the pressure, so if it starts out colder then it will end up colder... right??

Maybe my car was running better for some random reason, but I could have swore that when my FTP was taken out and my headlights were up it felt a little more powerful from what I figured was cold air coming in from a place it hadn't before, again, maybe just random feeling or something.

I don't know if it will matter or not but some people seem to think that if you have a cai on a turbo it will alow cooler air to be sent to the tb. I don't know just experimental for me but only cost about 35 bucks for the hole kit so I'm not worried either way.

Colder air is always better, no matter what. Even if it gets heated back up for whatever reason, cooler air coming in will still be cooler after being heated than hot engine bay air.

i think it looks really nice... i hope it gives you some sort of power gain also. i know when i did my CAI there was a big difference especially in the morning with the cool air.
