Many years ago, Smokey Yunik used hot intake temperatures to boost MPG. However, to make that work, he needed a turbocharger to keep the pressure up. (remember, hot air expands) Therefore, to recapture exhaust heat energy and use it for MPG, a turbo was needed, and it had to make about 15 pounds of boost at very low RPM.
When I lived in Daytona, I used to talk with Smokey from time to time. He was always willing to show me his latest project.
