Its about torque/ per rpm.

He pushed his engine very far outside of that. There is still plenty of power but not much useful force for every increased TP. For example as he reaches 50 mph in (I guess) 4rth he was at peak FE as far as the engine was concerned. Putting in the least amount of fuel to get the most torque. Any higher and its not available so you have to stack and push further.
