Although it's not an A-B comparison, I've got some data that would seem to bear that out.
The image below (if I can manage to link it right) is a log of an acceleration run I did the other day in my Audi. It's got a pretty large (22" x 10" x 3") cheap IC hanging under the bumper where it gets plenty of airflow. The car is running ~12 PSI boost.
The run started at part-throttle in 1st gear, then full in 2nd and 3rd. This represents a speed range from 20 to about 75 MPH.
The outside temperature was about 45 degrees F, and initially the air temp coming out of the IC was close to that number. But by the end of the run the air temp was 76 degrees! I would have expected a lot better considering the low boost, how large the IC is, and where it's located.
