• Possible etymology: The original phrase is actually hinted to in the expression "with a full head of steam". In the earliest days of steam engines, Watt style engines and their successors used a centrifugal governor to control speed. The faster the engine was to run the higher the weighted balls on the governor would rise until at full speed they were at their highest and farthest reach from the center: high or full speed was known as running "balls out".
