Centrifugal intake air temps

[Comin' in Hot]

Is it ok to use the OBDII data to measure intake air temps?

Under normal driving what is you IAT above ambient?

How much does the temp increase with a wide open pull?

How quickly does it go back down to its normal operating temp above ambient?

This was also an hour after a previous run.

Outside temps have alot to do with it too. On my tr35 i see 15* over ambient at 80mph in hwy. 90* day.
Full WOT pull same outside temp i saw 142*.
Thats on 21psi ysi

The highest I see at closed throttle is about 12* above ambient.
20* above ambient during the 1,320' using Meth, Air to Air "T" trim with ~19psi.

Another thing to add. If you can plumb the blow off valve before the IC that will keep some heat out of the IC.

I got done plumbing my water to air IC yesterday, it was 65* the IAC was at 75* with normal driving and went up to 82* after a 1/4 mile pull, it did cool down but it took awhile. I think one of the biggest problems is that the piping from my IC to the intake is all metal and heats up. I have a mustang shelby inspired fiberglass hood that im going to cut up and graft onto a mm/cv hood. it should help with lowering underhood temps, but i have too many other projects at this moment.

Note: All intake temps were measured using the OBDII data.

Where is your IAT sensor located?

Sounds pretty good to me. Make sure you can get good air flow over the heat exchanger. Box it in if possible.

It's located about 4" after the intercooler and about 18" from the throttle body

I have three fans pulling air through the heat exchanger and it's located low behind the opening of the bumper cover

Excellent IAC temp. What boost psi?

I would not necessarily assume "the piping from my IC to the intake is all metal and heats up" all this heat is transferring to the intake air.

I'm currently running only about 9 lbs. of boost.

The reason the piping concerns me is that the IC is cool to touch and the piping gets a lot hotter the the closer it gets to the throttle body, I should get an infrared thermometer to measure it. I thought about getting exhaust heat wrap to help keep it cooler.

Don't assume the heat on the pipes is transferring to the intake air. Under way with the throttle open maybe different. Be sure to check temps of other things in the same area. The heat maybe transferring from the charged air to the pipes and not the pipes to the charged air.

I'm pretty sure the heat is coming from the headers and convecting to the last charged air pipe before the throttle body. The IC is working because one side is hot and the other cool, and the next pipe is cool where the IAC is located.

And if I shut it off and restart it the heat soak is unreal.

Non-IC my fox is around 140-150 cruising. Open track temps get to 215. 1/4 mile about 190-195.
