Description Available in: Top Alcohol Dragsters may look like Top Fuelers, but they have significant differences. Whereas Top Fuelers use supercharged, nitro-burning engines, Top Alcohol Dragsters may use a supercharged methanol-burning engine or an injected nitromethane combination. The injected nitro cars do not use a transmission, and the supercharged cars have three forward speeds. Weights vary according to combination but are generally between 1,975 and 2,050 pounds. Like Top Fuelers, Top Alcohol Dragsters are restricted to a maximum wheelbase of 300 inches. A typical run is in the 5.2s at more than 270 mph.
