Borrow an infrared gun next time and shoot the blower immediately after a track session. Compare that to a street reading. The blower heatsoaks also.

You might try water injection. It is mechanical intercooling. The major car manufacturers tested it years ago and found it effective but never implemented it because they could not rely on the owners to keep the tanks full. The disadvantage over intercooling is that water injection cools the air only under load when the water is flowing while the intercooler cools all the air all the time. Both is best, in my opinion. I recommend the Aquamist kits. Vishnu Tuning did a little testing on a supercharged car and the results were posted in one of the Vishnu threads here. That car may already have been intercooled, though.
Agreed with the IAT's...although people here say getting IAT info is difficult. Also agree with the water/meth. I bet it's worth 50+ HP on a non-supercharged application once IAT's increase dramatically at the track. LostMarine just got a 535 kit and put a water/meth kit and will be doing a number of tests and posting on one of the other forums.
