One day (several years ago) I raced my way into the semifinals and was nervous as hell. For some reason I was concerned my water temp was a little high and that I need to cool the engine down just a little. The decision was made to run the electric fan until the burn out was complete. Pulled up to the starting line and lit the 1st bulb, reached over to shut off the fan but shut off the electric fuel pump instead. I learned that day that my car could Launch and pull through 1st gear with just the fuel in the carb.
