Skicker.. take time to consider:

"Syncopated Pandemonium"

Think about it!
Any internal combustion engine, is working together in unison (pistons/rods/crank/camshaft/valve train..etc) in sync... SYNCOPATED rotation...
Now.. while internal parts are working together, there is violent reactions to the forces created within... pistons hitting the cylinder head combustion chambers...for example..or the incredible speed of the rotating crank...
Which gives you PANDEMONIUM... that creates, what else? Horsepower.
