Best spot to mount IAT?
MS is in and I'm preparing for AFM removal, what do you think would be the best place to mount IAT? keeping in mind heat soak etc etc.
I've bought the GM IAT and will eventually use it, but thinking the stock sensor (in the photo) might be better to use; in that it's heaps smaller easier to insulate, plastic body doesn't absorb and transfer bonnet-soaked-heat into the sensor as much as the GM metal body sensor.
I've also done a rough characteristic check on the stock sensor...looks a bit wonky on the graph, probably need a heaps more data to get a function out, its taking shape.
Maybe some pics of where and how you have yours for some inspirations?

2. or is the induce air temp as air travels across the plastic intake pipe is too negligible to worry about? If this is the case then it make more sense putting it in the air box.
3. Wonder if someone mounted two sensors; one at either end of the intake pipe and get a rough idea of temp difference as air travel from filter to TB...would be interesting, because once you know that value you could in a way compensate for the difference in the MS firmware?
4. What about taking the above further and put an air temp sensor inside the intake manifold to see as close as possible what the air temp is as it enter the chamber.
Maybe it's all unnecessary to know accurate IAT in the whole scheme of things.

While youre at it you can do this. It will keep your hands away from the keyboard
revlimiter.net - Intake Isolator
revlimiter.net - NACA duct intake
Unless you already have something like than.

I have mine in the coldside end tank and it helped a lot. Still heat soaks after I shut the car down and start it hot, though.
Edit: missed that you're N/A. Here is how I ran mine previously:
(you can just barely see it behind the upper rad hose)

On an n/a car it doesn't much matter because the intake air temp is not that different from the airbox to the throttle body that it's going to cause problems tuning. The airbox is near the toasty warm exhaust parts, and the crossover tube is bathed in air that's heated by the radiator. I took my IAT and zip tied it near the open end of the snorkel that feeds the airbox. I intended that to be somewhat temporary as I was expecting to be turbocharged much sooner, but anyway, the car was tuned with the sensor where it is so I'm not moving it until I do go turbo. It's far enough away from exhaust parts and not in a hot airstream, and it never gets soaked to the point that it substantially affects how the car runs.
