Why do smaller engines have more horsepower?

Engines make power by moving air through them. A smaller engine can move more air than a larger one by having better flowing heads, turbochargers or revving much higher or any combination thereof. The more air you can move through an engine matched with proper fuel, the more power you’ll make.
