When my IC outlet temp reaches 120-130 degrees at the track, I can feel a 'seat of the pants' power decrease.

Somewhat objective example:

C6 Z06 has faster acceleration at that temperature and at any mph range - despite a higher RWHP P/W ratio.
Z06 has more torque, but when the 930 IC is cool, it is quicker than the Z06 in a straight line.

No numbers, but a fairly significant difference.

The fan will keep everything cooler - intercooler, intake manifold - but at 90 degrees ambient, trying to correct for and comparing against a 60 degree baseline will probaly prove inaccurate, if not impossible.
