What You'll Learn
Tony Schumacher: the most prolific active driver
Tony Schumacher, born on December 25, 1969, is an American drag racer and the most prolific active driver in Top Fuel. He is the son of NHRA legend Don Schumacher and has established himself as one of the greatest drag racers of all time. Schumacher attended Maine South High School in Park Ridge, IL, and later St. John's Military Academy in Delafield, Wisconsin.
Schumacher's racing career is highlighted by numerous achievements and records. As of the start of the 2022 season, he held the all-time NHRA Top Fuel records for wins (86), poles (84), and championships (8). His eight championships include six consecutive titles from 2004 to 2009, breaking the previous record set by Joe Amato. In 1999, Schumacher became the first driver to exceed 330 mph in competition, and in 2005, he set the world record for the fastest 1/4-mile top fuel run at 337.58 mph in Brainerd, Minnesota.
Schumacher's success in the NHRA Top Fuel class is further exemplified by his performance at the inaugural NHRA Carolinas Nationals in 2008. At this event, he surpassed Joe Amato as the driver with the most wins in NHRA Top Fuel history, claiming his 53rd career victory. Additionally, in 2012, Schumacher became the first top fuel driver to reach the 330 mph mark in the 1,000-foot NHRA era.
Beyond his records and championships, Schumacher has also contributed to the sport's safety advancements. In 2008, he collaborated with the NHRA and other renowned drivers to develop a sensor that detects engine backfires in nitromethane engines. This innovation protects drivers by shutting down the fuel pump and deploying parachutes in response to engine explosions. Schumacher's dedication to his craft and his impact on the sport have earned him a place among the greats in the world of drag racing.

Shirley Muldowney: the first female driver
Shirley Muldowney, born on June 19, 1940, in Burlington, Vermont, is an American auto racer. She is also known by her professional names "Cha Cha" and the "First Lady of Drag Racing". Muldowney was the first woman to receive a license from the National Hot Rod Association (NHRA) to drive a Top Fuel dragster. Top Fuel dragsters are the quickest-accelerating racing cars in the world, with the fastest competitors reaching speeds of 338.94 miles per hour (545.5 km/h).
Muldowney faced significant opposition from those who felt that women had no place in drag racing or any form of motorsport. She noted that the NHRA fought her at every step, but eventually, they conceded that her participation was good for the sport. Muldowney's talent and success spoke for themselves, and she went on to win the NHRA Top Fuel championship in 1977, 1980, and 1982, becoming the first person to win two and three Top Fuel titles. She also won a total of 18 NHRA national events.
In addition to her racing achievements, Muldowney was voted the first woman member of the 10-person Auto Racing All-American team by the American Auto Racing Writers and Broadcasters Association in 1975. She was also named Drag News Top Fuel Driver of the Year in 1976 and 1977, and Car Craft magazine's Person of Year in 1977. ESPN ranked her 21st on its list of the Top 25 Drivers of All Time in 2008, recognising her as the first woman to win a major racing championship.
Muldowney's career was not without setbacks. In 1984, she was involved in a serious crash that crushed her hands, pelvis, and legs, requiring multiple operations and months of therapy. Despite this, she returned to racing in the late 1980s and continued to compete throughout the 1990s, mostly without major sponsorship. She retired at the end of 2003. Muldowney's impact on the sport is undeniable, and she has inspired many women to pursue drag racing.

Top Fuel's extreme speed and acceleration
Top Fuel dragsters are the quickest-accelerating racing cars in the world. They can accelerate from a standstill to 100 mph (160.9 km/h) in as little as 0.8 seconds, which is less than a third of the time required by a Porsche 911 Turbo to reach 60 mph (96.6 km/h). This acceleration is possible due to the massive amount of force generated by the engine, which is over four times that of gravity, similar to the force exerted by the space shuttle at liftoff. The dragsters can reach speeds of over 330 mph (531.1 km/h) and finish a 1,000-foot (304.8 m) run in approximately 3.6 seconds.
The extreme speed and acceleration of Top Fuel dragsters are achieved through a combination of engine design, fuel injection, and aerodynamic features. The engines are designed to generate a significant amount of power, with a high revolutions per minute (RPM) rate, and utilize a constant flow fuel injection system with approximately 42 fuel nozzles. The fuel used, typically a mixture of methanol, nitromethane, and gasoline, contains oxygen in its molecular composition, allowing the engine to burn up to 7.6 times more fuel than a gasoline engine, resulting in higher power output.
The massive airfoil over and behind the rear wheels contributes significantly to the downforce produced, which can peak at around 12,000 pounds-force (53.4 kN) as the car reaches top speed. Additionally, the exhaust gases escaping from the open headers at maximum throttle can generate about 900–1,100 pounds-force (4.0–4.9 kN) of downforce. The combination of these factors enables the dragsters to maintain traction and stability despite their incredible acceleration and speed.
Safety is a critical consideration in Top Fuel racing due to the extreme speeds and acceleration. The National Hot Rod Association (NHRA), which sanctions much of drag racing in the United States, has implemented various safety measures. These include the use of full-face helmets with head and neck support (HANS) devices, multi-point safety restraint harnesses, and fire-resistant racing suits and gear for drivers. Additionally, the cars themselves are equipped with on-board fire extinguishers, synthetic "bullet-proof" blankets to contain debris in the event of an explosion, and enclosed roll cages to protect the drivers.
The Top Fuel category has also served as an inspiration and stepping stone for many female drivers in the sport of drag racing. The Top Alcohol Dragster category, in particular, has become a destination for women, with female drivers finding success and using it as a platform to progress to the Top Fuel class.

Top Fuel's engineering and mechanics
Top Fuel dragsters are the fastest class in the National Hot Rod Association (NHRA) drag-racing series, capable of reaching speeds of up to 338.94 miles per hour (545.5 km/h) and finishing 1,000-foot (304.8 m) runs in just 3.641 seconds.
The engineering and mechanics behind these cars are truly remarkable. Firstly, let's look at the engine. Top Fuel dragsters use a supercharger, which is essentially a belt-driven air pump that force-feeds the engine. This supercharger requires an immense 700 hp to run. The engine itself is a beast, with 16 pushrod-activated valves, two spark plugs per cylinder, and a total displacement of 500 cubic inches. The fuel is injected through a constant flow injection system, with approximately 42 fuel nozzles. The fuel mixture consists of 90% nitromethane and 10% alcohol, which provides more power than gasoline due to its oxygen-rich composition.
The extreme forces generated by the engine cause significant wear and tear on the car's components. For instance, the crankshaft bearings and valve springs are often destroyed during a pass. As a result, the engine requires a complete rebuild after each run, which is expertly accomplished by a team of eight mechanics in a mere 40 minutes.
The car's acceleration is equally impressive, going from 0 to 100 mph in just 0.8 seconds. This acceleration subjects the driver to an average of about 4.0 g0 (39 m/s2) and can peak at over 5.6 g0 (55 m/s2). To put that into perspective, it's like experiencing several times the force of gravity.
The massive airfoil over the rear wheels provides additional downforce, peaking at around 12,000 pounds-force (53.4 kN) when the car reaches speeds of about 330 mph. The car's steering is also unique, with the front wheels slightly off the ground and the track's grip assisting in pulling the car in the desired direction.
Safety is a critical aspect of Top Fuel racing. Before each race, the mechanical crew adjusts the fuel levels to select power outputs that are just below the limits of tire traction. This is because excessive power can cause "smoking the tires," leading to a loss of control and potential crashes. Additionally, due to the extremely loud engine noise, race announcers advise spectators to protect their ears, and earplugs or earmuffs are often provided at the entrance.
