As you can see, there are still stickers on it so I can return them in case this doesn't work. I'll compare the IAT and MAF reading to my friends Mustang equipped with K&N FIPK, then we'll really know if it works :p

I like...

the way it looks. I've been thinking about doing something like this for my car. It would be the economical way to do it. Let me know how things work out. Where exactly is the filter located? Did you cram it in the wheel well somewhere?
 
I think it looks pretty good man for a ghetto install.. it's definately different from what you normally see. I kind of like the shield look of the stocker piece in there.
 
There's VERY little material to clamp to on the backside of the MAF to air filter adapter thingie - are you sure that will stay connected over time? It's only about 1/4 inch of plastic.
Accufab makes an adapter to mate to the MAF --> http://accufabracing.com/general.htm#MassAir $40.00 to lose the ghetto effect. Nice idea though. I wanna rig up something like this myself because the underhood temp is HOT! They say a 10 degree drop in inlet air temp is worth 1 HP. Drop 50 degrees and you found 5 free HP.
 
Just came back from the track with my friend and brought back some numbers from data logging with Diablo. My car is a 2001 Mustang GT and his is a 2004 Mustang GT Convertible with K&N FIPK. We both datalogged 2 runs at the track. Tonight temperature was 59 F.

2001 Mustang GT with Ghetto CAI

ECT Average = 185.5987147 F
ECT MAX = 196 F
ECT MIN = 168 F

IAT Average = 77.95115681F
IAT MAX = 88 F
IAT MIN = 64 F

MAF Average = 1662.522879 g/s
MAF MAX = 25434 g/s
MAF MIN = 485 g/s

2004 Mustang GT convertible with K&N FIPK

ECT Average = 202.2326192 F
ECT MAX = 212 F
ECT MIN = 194 F

IAT Average = 89.42107564 F
IAT MAX = 128 F
IAT MIN = 66 F

MAF Average = 2133.267599 g/s
MAF MAX = 21843 g/s
MAF MIN = 404 g/s

It's too late, I'm sleepy and I can't think straight. I'll comment on the result another time.
 
I personally don't think it looks too ghetto. In fact, I've seen far worse, such as tin foil wrapped around hosing for an intake.

I see you've also got some solid intake temperature numbers for us to look at. Looks like the results turned out in a more positive light. Good job. I might have to look into doing this myself. Just imagine how well it might work on a motor with serious engine upgrades. :nice:

As you can see, my average IAT is lower than the K&N FIPK by 16F and that my maximum IAT is much lower too. But we also notice while data logging that once the cars are moving, the IAT of both car are pretty much the same. So the only advantage I have is idle and low speeds.

Here's another interesting thing. I used a cheap knockoff cotton air filter while my friend is using genuine K&N air filter. Do you see the difference? I averaged around 1662.xx g/s of air while he averaged 2133.xx g/s whioh is much more. From the results, we can see that K&N air filter sucks in more air mass than a cheap knockoff, so there's a reason why it cost more, it's because it works better. The more air mass that is coming in, the better.

So, even though I have a lower IAT, I have less air mass coming into the engine because of the cheap knockoff air filter.
 
The fact that you gathered data from two different cars renders your data meaningless IMHO.

You need to redo your experiment using the same car for both styles of intakes.

Two points to add to this. I would think that even by just leaving the complete stock intake, you would have cooler IAT temps at idle. The snorkel on the stock intake is getting the air from the same area. Second point is about the airflow. The air flow diffrence is most likely caused by the stock plastic air intake tube that goes to the TB. It is not a very smooth flowing tube with many small restrictions. No matter how good an air filter is, it's flow capacity is limited by the rest of the intake system. Some very interesting results over all though :nice: . Oh and the other Stang was an 03 :D .

True the tubing to the TB would be a restriction. Acutally, if you think about it that way, a K&N CAI would be much better in this sense because his data was gathered from the MAF which is before the tubing you are referring to. So, there will be an even larger airflow difference to the engine, if you were able to gather the info at the TB.
 
I've made a graphic of the IAT and the RPM of both cars on the 1/4 mile run. As you can see, the CAI has lower temperature. Both IAT will match at 66F at around 5200-5300rpm in 3rd gear meaning about close to 100mph. So, at high speed, ghetto CAI and the K&N FIPK have the same IAT thus they are equal at that speed.

Also, if you look closely, the other dirver can shift faster than me :p

no documented Ets to show that any CAI will perform better than a straght K&N on the MAF, under the hood. The graph is cool looking but unless you do the test on one car or the other, doesn't prove anything. Piece looks clean for homemade though.
