![]() The engine of a Top Fuel dragster generates around 150 dB of sound at full throttle, enough to cause physical pain or even permanent damage. The massive airfoil over and behind the rear wheels produces much more, peaking at around 12,000 pounds-force (53 kN) when the car reaches a speed of about 330 mph (530 km/h). Additionally, the burnout applies a layer of fresh rubber to the track surface, which greatly improves traction during launch.Īt maximum throttle and RPM, the exhaust gases escaping from a dragster's open headers produce about 900–1,100 pounds-force (4.0–4.9 kN) of downforce. In recent years, only exhibition races in Martin, Michigan's US 131 Motorsports Park are run as Top Fuel races to the quarter-mile.īefore their run, racers often perform a burnout in order to clean and heat tires. The International Hot Rod Association, which now sanctions Top Fuel in Australia, dropped the distance in September 2017 after Santo Rapisarda, a car owner who often runs NHRA races in the United States, pushed for the change. The shortening of the distance was used by the FIA at some tracks, and as of 2012 is now the standard Top Fuel distance defined by the FIA. The rule was changed in 2008 by the National Hot Rod Association following the fatal crash of Funny Car driver Scott Kalitta during a qualifying session at Old Bridge Township Raceway Park in Englishtown, New Jersey. This subjects the driver to an average acceleration of about 4.0 g0 (39 m/s2) over the duration of the race and with a peak of over 5.6 g0 (55 m/s2).īecause of the speeds, this class exclusively races to only a 1,000 foot (305 m) distance, and not the traditional 1,320 feet (400 m). Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 339 miles per hour (545 km/h) and finishing the 1,000 foot (305 m) runs in 3.62 seconds.Ī top fuel dragster accelerates from a standstill to 100 mph (160 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (100 km/h)) and can exceed 295 mph (475 km/h) in just 660 feet (200 m). ![]()
