The NHRA Motorsports Museum includes an interactive display that simulates the massive amount of nitromethane that pours into each cylinder of a Top Fuel or Funny Car engine. The first seconds of the display show the amount of fuel being injected during idle before extra nozzles are added under wide-open throttle. This display shows a flow rate of 8 gallons per minute (64 gallons per minute for all eight cylinders) that came from the Waterman Racing Enterprises Super Bertha fuel pump used by world champions Gary Scelzi and John Force in 2000. Today's Funny Cars burn anywhere from 88-94 GPM, Top Fuelrs slightly more.
