Time for another poll! CAI on a turbo... worth it or not?

Time for another poll! CAI on a turbo... worth it or not?
I just got done with a thread that has differant stories from both sides, some saying it is good because it's cooler air entering the turbo before it is compressed so there for it is cooler air when it reaches the intake. Others on the other hand say it makes the intake to restrictive. I'm going to go ahead and try it on my car for ***** and giggles but I would like to know what yall think. Thanks for the input!

well what im talking about is that it has more bends than just a tid with a filter on the end of the maf. so instead of getting the air right there it has to get it even further away threw the other bend. Here is a pic of the cai I'm talking about

i never liked the metal tubes for the intercooler kits, plastic and rubber tends to heatsoak much less than metal does, i would be more concerned about that than the CAI setup. they add to the look but for functionality they are counterproductive.

Of course it's worth it. Anyone who says otherwise doesn't have a clue what they are talking. ANY drop in intake temperature, before or after the turbo, directly results in a corresponding drop in temperature at the throttle body. Thus, cooler air into the engine.
This has all been thoroughly discussed before, of course.

thanks aaron for the input! I didn't see anything else on cai on turoed cars but I have been known to be blind Anyways I'm just connecting the filer right now and will take it for a drive later on today and post the results. If anyone else has input please post it! OH aaron you don't think that "sucking though a long and curvier straw" would restrict flow??? Thanks.

Not sure what CAI means, but I think your all referring to air filters mounted outside the engine compartment... right? Doing this is a fabulous idea and is the key to dropping intake temps. Some say the FMIC will do its job etc. and you don't need to mount the filter or even run one.... bad idea!
On a 95deg day I ran my car 140mph steady for about 5 miles @ 18-20psi (T60-1) and my intake temps were about 32-42C via Wolf EMS laptop...and the water temps about 93C which is getting up there but held steady. I have since relocated my oil cooler out of the radiators way so that should help but haven't tested. I have a BoMex bumper with the center slit opening and I mounted the oil cooler behind that right above the Spearco (27 x 8 x4). The only thing I had to do it buzz out an opening in the safety bumper..
Now for those of you that still run an AFM, don't get them to wet or you'll zap it.

CAI, ahhh yes.. makes sense. I always cal it FMAF. Front mounted Air filter. The "CAI" name has kinda runs its course with me because thats what every manufacture calls there intake, and some are not cold, infact there just the opposite. The stock air box is actually better on some cars.

It shouldn't matter where the AFM is in a cold-air-system since our system is a mass air which measures the volume of air it takes in, not temp. So, you should just mount it in a safe place that it won't get wet or slammed w/ debris. I think the ECU does make some fueling decisions based on coolant temp though...

Your right about the ECU compensating. The AFM reads the amount of air, however the air temp sensor reads the temp (of course) and both send info to the ECU, like all the sensors and thats why when something is not sending correct info to the ECU it gets confused. Its been a while since I had a oem ecu but thats the basics.
You guys should run the AFM after the FMIC.....much better and then you can run the "CAI" anywhere you want... I did that years ago and the lag/response is better. There are some guys still running this setup I think.

see I don't care much about hp output of this mod I just mearly want the intake temps to be less so that I don't have to worry about detonation as much. Hey raising arizona what exactly do you mean by having the afm after the fmic??? Do you mean actually puting just a filter on the turbo and putting the afm in the fmic piping after the intercooler???

that right. This way you can put the CAI anywhere you prefer. Never done it with an S4 AFM but the S5's work great. I thought the response was better. If I remember I had to extend the sensor wires but other than that it was easy.. Lets call it an Inline AFM mod.

A CAI is even more important on a boosted engine, because the intial temp gets multiplied when the air is compressed. It blows my mind how many people will run standalone EMS, FMIC, aftermarket turbo, upgraded injectors, and not even bother with the air intake location.
#25
If I really get bored, which probably won't happen, I'll go out and record some air temp numbers with and without my CAI. I did it in the summer time, and it made a huge difference in intake temps.
