It's a big racing weekend with the Indy 500 and the Coca Cola 600 racing on Sunday. A lot of people don't consider racing a sport and the drivers athletes but I disagree. Race drivers spend almost as much time in the gym as they do on the track. The engineers that build these amazing racing machines are much more than grease monkeys too.  What used to be a fraternity of grease covered good ol boys has now been replaced by techno-nerds with a passion for making things go fast.

You may have heard the expression that motor is running in "full song". It's a term used to describe an engine that is operating at optimum efficiency. In this video you can actually hear the song of the motor, listen carefully I bet you can even name that tune!
