AIT ~140 Degrees....What's yours? Im thinking about putting Water Injection
My AIT is seeing from 115-140ish Degrees....(BTW that wasnt even boosting at all coz Im not tuned yet)
What's yours?
Im thinking about putting Water Injection just pass the outlet in the FMIC.
What do you guys think?
Will I benefit much?
Yes just water I just want it for cooling effect....not Octane substitue

At the race track 37r@34psi on a Galant vr4
90 degree day outside
Idle beforerun AIT = 105
after 1st gear AIT = 113
after 2nd gear AIT = 122
after 3rd gear AIT = 134
after 4th gear AIT = 143
Now my intercooler sucks, and it was hot out, and I do not have a CAI on the car so it was sucking the air from right behind the radiator. Do you have an upgraded intercooler, and where is your intake pulling the air from. It sounds like it is just sucking the hot engine compartment are into your turbo. 140 degree intake temps sucks and will rob power.

Are you on an AEM EMS, or the Stock ECU with MAP? If so your AIT might not be setup correctly. I dont think it would be possible to see 140+ degree temps if you have an intake pipe. Put a new sensor in and see if that fixes the problem. Also check the settings for the sensor to make sure that the Voltage matches the air temp.
Another way to test the AIT is to pull it out of the car and data log and see what it reads. If you know the outside temp is 100 degrees and your AIT is reading 120 then there is something wrong.

Im getting tuned in 2 weeks and Im expecting 630whp+(on race gas) and just dont want to be heat soaking thats why I thought of putting water injection maybe use M2 or M3 nozzle just for mist to make the air cooler.

It is my understanding that the most beneficial aspect of meth is it's ability to cool the air charge rather than raising the octane of the fuel. Something to consider.

Do you have an intercooler sprayer? You could try making or getting a cold air intake made. Putting the filter out of the engine bay, sucking in ambient air. Don't see TOO many evo guys doing that, but DSM guys do it constantly. It helps quite a bit. Or possibly a shield around the filter to box it away from the radiant heat in the engine bay.

Are we talking about intake temps at the MAS (stock ECU) or charge temps at the throttle body (AEM, etc)? Two completely different IAT values. I see temps in the 140s at the end of a drag run post intercooler, it's not uncommon. A better IC can keep that number a good bit lower. A cold air intake doesn't help significantly with this reading (post IC) since any drop in intake temp at the filter gets cut down by intercooler efficiency. Using typical values a 5C drop at the filter only works out to a 1C post IC.
