Thanks that helps a little,
Let me give some insight here. We know WAI helps mpg. I have been playing with my CooperS with a supercharger on it. When air is compressed such in my case the air across the inter cooler can run 130 degrees. So there for I have no reason to heat my air I am already heating it. What I want to know is if anyone has come up with a number for intake air temp. I have found that if I block off 1/2 my intercooler in weather as high as 50 degrees my mpg jump 5 to 10 based of the type of road which I am driving. This is with out hypermilling involved just striaght motoring.
