I'd really like to see some more IAT data under a range of conditions. So far, it looks like IAT's run about 20-30 degree hotter than N/A under everyday driving. What would be telling is to track IAT after all temps have stabilized after a 20 minute light cruise, then jump on it and see how fast it climbs. One member here programmed his PCM to kick on the fans under 30 MPH no matter what. This might not be such a bad idea. Heat soak / underhood ventilation is already a problem with a stock GTO/Monaro, and I'm beginning to see why the Aussies made such a big deal about it, as us Yanks tended to play it off. Add to that a supercharger that heats the air considerably more than stock and there's no question that heat soak is a big issue.
Just today, I made a 150 mile trip and, as an experiment, I immediately opened the hood when I stopped at a rest area about 3/4 of the way back. After about 15 minutes sitting, IAT's were about only about 10 degree over ambient, compared to an expected 70 or so before I applied the intake insulation and probably about 50 degree with the insulation. My fondest wish is that Autosport Development make a commercially viable version of their racing hood. The PYFC hood at least moves in this direction, but I'm hot sure, given the size of the outlet holes under the hood, how effective it is at actually ventilating the engine compartment. A pair of louvered panels that could be cut into the stock hood would be a Godsend.
