IMPORTANT-HOW TO reduce AIT/log info inside.CAI installed

[Car Cannibal]

The best way to reduce AIT is to go Preturbo Injection, winterize your turbo and probably not more $$ than the bigger filter and hard piping.

kmoore, you can still do the same thing I did, you just have to be a little more creative.
Your still going to have to cut out that entire panel that sits under that filter, then you just do the same thing I did with the 90deg pvc pipeing, my exact one should do if you manipulate it to work, but you could need a longer one? The only thing I see that would make it difficult for you to do exactly what I did is not your upper intercooler pipeing, but your large air filter.

Uh no. Water injection pre turbo can still ruin a turbo. Anyway the temperature is not read by the MAS regardless. If you want water injection, best place to put it is pre TB and post intercooler. Or just inject directly into the manifold.

You most not be that current with Preturbo Crimson. I run Pre and Post Turbo Injection and many others do and don't have any damage but a turbo that pushes much colder air. We're not in the 80's you know, things have come a long way.

Cannibal, its been discussed before. Many feel that the tiny droplets and vapors from a meth/water injection setup preturbo can and eventually will damage/erode the compressor.
If you choose to do it anyhow, more power to you, enjoy the benefits (cause we're not denying the benefits)!
But I would hardly recommend for someone else to do it.

I would, however, say that the "best" way to decrease AIT's is to not be sucking up scorching hot engine bay air.

Actually, while we're at it, do you have any logs of before and after for your setup? I'm interested to know exactly how well your methods really do work.

Coating headers, exhaust housing and downpipe will go a LONG way to reducing under hood temps, so will running more base timing and cruise timing due to lower EGTS.

Preturbo Injection does gave me 1 more pound of boost on my MBC setting. It's literally what happens in the colder months for you Southern DSMers. CAI will not give you a lb of boost over your current settings, it's not nearly as cold.

This is will reduce underhood temps a lot, but that doesn't mean will reduce AIT's much.This may reduce coolant temps in my opinion. Even, if you wrap/or thermal coat/ every single pipe or anything else, your compressor housing is attached to turbo's CHRA and this makes the air hot enough, without even pointing that compressing air, gives additional heat. In most cases the LICP runs very close to radiator and WG dump tube and that fact doesn't help at all. Pre turbo injection cools more probably, I never had it and can't tell. This thread in general was about CAI and the pros or cons from it.

I'm sorry but I just read that first post. If I read correctly you measure the results of a CAI on the temps then went into how other FMICs did with intake temps. But I don't remember reading what the temps were before you put on the CAI. I probably read wrong but I just want to make sure. What were the temps like before the CAI?

Actually like I said earlier, when I did my CAI setup WITHOUT touching boost controller I did spike higher and hold more psi towards redline... This is on a e316g though, denser air in that little compressor may be much more significant on this setup than another...

Like noted, I dropped around 30degs average with my CAI setup.

Too bad I never logged this AIT before. I have only one log, I posted results, somewhere on page one. The difference is only like 5-10*F, but it is not compareble. On this log here I drove 20 min. around, seat in traffic or at the light. After that I made several pulls, and drove the car totally for like half hour. Plus it was a daytime 3PM, bright sun around 75-76*F. The other one was after cams install, Car sat with hood open for may be like 10 min, idling and then I took off. And it was like 79*, but at night, no sun, no other cars, just I closed the hood and drove it. Didn't have any time to get heat soaked.

Drive your car for like half hour, make several pulls and then stop it and just see how hot your LICP, UICP and IM are. You'd be surprised.

Where did you buy the 4'' piping?

I bought it locally at some speed shop. You can get it at Vibrant, or JMF probably.
