I did happen to check out some of the AIT information on the drive home.
I have 3 AIT's set up in the car.
#1 Pre SC (at the filter) [PLX sensor]
#2 Post SC (in the tube between the SC and the Aftercooler) [PLX sensor]
#3 Post Aftercooler inside the Stage 3 plenum (ECU sensor)
Most of the drive home, at highway speeds, I would see:
Ambient temp was 60-70 degrees. I hit hot and cold patches the whole way.
#1 96 F
#2 160 F
#3 105 F
When I would give it the beans, of course #2 would sky rocket, but #3 would stay solid. On the down side, when I stopped for gas, #3 would rise up to 120'ish F, but would come back down to 105-110 F within 15 minutes of driving.
Thoughts?
Thanks for sharing the data! Now we have a direct comparison between manifold types. The Gen 3 looks a bit more efficient than Gen 1 based on the cruising data. If I'm just cruising in vacuum, I'm typically seeing a 10C (50F) drop between #2 and #3.
When I get into boost, #2 skyrockets as expected, while #3 slowly climbs. Clearly a major transfer of heat through the dinky Gen 1 exchanger. Hard to do a controlled comparison under boost of course.
Might be of interest to do a more direct comparison in person, under the same conditions.

Are you filling up your tank while your car is running?
