NHRA dragster's fuel pump in action

A top fuel dragster makes impressive use of a 500-cubic-inch engine block machined from a solid chunk of aluminum. That 10,000-horsepower engine propels a 2,300-pound car from the starting tree to 100 mph in less than a second. And it needs a lot of fuel to do it.

Some visitors to the NHRA Museum caught a dragster fuel pump in action. The red Lego-like contraption at the lower left is a Waterman Super Bertha fuel pump, set up to deliver more than eight gallons per minute at wide-open throttle to each of the eight cylinders. You can see what the resulting jet of nitromethane looks like in the video after the jump.
