Turbo chargers work on the exact same principle, the gasoline engine works on gasses at a higher potential and the turbo charger works on gasses at a lower potential, thereby more fully utilizing the energy of the gasoline. If you can understand these well established principles, not just based on theory but in actual practice, I don't see why he'd disagree with us.

That analogy might apply if turbo cars were driven nearly full throttle all the time.

If an engine has sufficient power without adding a turbo, would adding a turbo increase FE?
