what are your air intake temps? Options

[match220]

Hey guys,
Since I have a Gen III in my st204 w/o a GTFour body kit I've been watching my intake temps carefully. (Autronic brand IAT is mounted as close to the engine as I can get it without it being directly above the engine). When I first finished building the engine for the car I still had the insulation on the hood and had a semi covered enclosure for the air filter. The hottest my air intake would get was 80C (crazy!) and that was sitting in traffic with no airflow over my I/C (front mount). Then driving it was around 65C. At night driving it would go down to 60C.

After pondering what to do and talking with some drifting friends, I ended up raising up the rear of my hood 4mm, which isn't even noticeable, removing the weather stripping. And also removing the insulation from the hood and making a full enclosure around the airfilter out of plastic and Plexiglas . NOW my air temps are 60C on a hot day sitting in traffic with no air flow over the I/C, and 45C moving on the freeway on a hot day. At night on the freeway it is 40C.

relevant intake info(shortened from above): big fmic (air/air), and Autronic brand IAT mounted two feet from TB inlet, not directly above engine. Numbers below are before and after a full air filter enclosure and raised rear of hood 4mm.

-------------------------Before-------After
hot day in traffic------80C---------60C
hot day on hwy-------65C---------45C
night on hwy----------60C---------40C

(80c is 176f, 65c is 149f, 60c is 140f, 45c is 113f, 40c is 104f)

So now that I've mentioned my numbers, I would like to know what your numbers are. I'm expecting it to be cooler once I get the hood vents. I would like to know what the norm is for this engine. Also please mention if you have the fmic or tmic
