Cold air Horsepower gain info.
Did some looking through my old engine books, and here is the amount of increased HP you can expect in the cold:
The gain in brake HP will be approximately 1 percent for every 5 degrees in intake air temp drop (degrees are in C) *or* approximately 1 percent for every 9 degrees Fahrenheit.
So, if the engine compartment is around 100 degrees, but its 30 outside, someone could expect about 8% more ponies just by getting that cold air into the engine.
