I'm curious: what are your average coolant temps when the car is warmed up?
This is only a problem though when stopped at idle, or I suppose at VERY slow speeds, like stop-and-go traffic. As soon as the car is moving steadily, the air in front of the radiator (and below the IC) is pressurized, the upward flow through the IC resumes, and the AITs drop fast.
Make sense?

Homey don't play dat
OK here is the most awesome sketch I could muster in 10 minutes. Here is a side look at front of nose/engine area, car traveling right to left. The outline of car/hood/splitter is in green and forms the boxed-in area in front of the radiator/IC. IC is blue. Radiator is red. Engine is black. Airflow is dark arrows.
First image is what the flow looks like when the car is moving at speed and the area in front of the radiator is pressurized.
Second image is what the flow looks like when the car is sitting still and the fans are running.

Not yet. Funny, I wondered if that is what you might have been thinking. I am still waiting for that GB extractor hood deal at CR. If it does not happen soon, I'll DIY a hood vent.

Good question. If I put fans on the IC, and wire them in parallel with the rad fans, then the second scenario never happens; if the rad fans come on, then the IC fans will be on too, and not backflow.
Plus, if I want to get really crazy, I could have the Adaptronic monitor the IAT, and if it gets above a certain temperature threshold, have it turn the fans on (Rad and IC). That way if the IC heats up from boost, or I am sitting at a light, either way it gets cooled off. It would just be another OR function. Just a matter of changing some settings in the Adaptronic. No need to add another sensor even. Easy.
