NHRA Nitromethane Power
This car's engine is producing about 5000 horsepower. This photo is not that recent. Today's version of this Top Fuel Dragster makes about 7000 horsepower with it's 500 CID engine. Runs on Nitromethane fuel, has no gears, and hits speeds of 330+ miles per hour. Most likely the loudest thing you've ever heard, enough to vibrate your internal organs! How about 0-100 in less than one second!!!!
That's Shelly Anderson driving, a few years back, with the late Buster Couch at left, pushing the go button.
Jan 2013 Update: I've uploaded a cleaner version of this old scanned photograph (1995?)
