So you guys are saying 1% power increase with nothing else changing? I was thinking the #'s could be more because the 10 degree decrease or whatever could allow you to turn up the boost a little, no?

Where'd you guys hear about the 10 degrees equals 1% rule? I've never heard that one before.
For every degree lower in intake temp, it's one degree lower in exhaust temp.

How about all the people who have cone filters sucking in air from the engine bay. Im not sure but i would estimate the air in the engine bay to be well over 250 degrees. Do the math.

Thats only part of the equasion. Each 25 degree reduction requires 1 point less octane. Meaning you have more available octane = less detonation / preignition.

well cold air is more dense, so you need more gas to run at the same mixture or cold = leaner, hot = richer
