Adiabatic Engine - Hot Vapor Cycle Engine - Henry "Smokey" Yunick

He was able to get a big increase in efficiency. His engine used a low pressure turbocharger and very hot intake air. He had a secret method of avoiding knocking. It may have been water injection.

I think I have an article about this in a Popular Science magazine.

I found another forum discussing this topic here.
Engine & fuel engineering - Smokey's Adiabatic Engine

Nice link andyman. This sounds like a dream come true. I wonder if we'll ever see this kind of thing on the road in our lifetime?
