Information about nhra dragsters?

Top-Fuel Racing refers to a class of drag racing in which the cars are run on 85% nitromethane and about 15% methanol (90% nitromethane, 10% methanol under FIA) also known as racing alcohol, instead of gasoline. The nitromethane used to power the engines of top fuel dragsters costs about US$30 per U.S. gallon (US$8/L). Top Fuel dragsters use between 10 and 12 U.S. gallons (38 to 45 L) of fuel for a complete pass, including the burnout, backup to the starting line, and quarter-mile run. The engine generates about 3.4 times as much power as a similar displacement engine running gasoline.
