Top-Fuel Racing refers to a class of drag racing in which the cars are run on 85% nitro methane and about 15% methanol also known as racing alcohol, instead of gasoline. The nitro methane 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 makes about 3.4 times as much power as a similar displacement engine running gasoline. |
