Bracket racing is a form of drag racing that allows for a handicap between predicted elapsed time of the two cars over a standard distance, typically within the three standard distances (1/8 mile, 1,000 foot, or 1/4 mile) of drag racing.
Rollout or rollout allowance is an adjustment in timed acceleration runs used by North-American drag racing and enthusiast magazines [citation needed] to create approximate parity over time between historic 0 to 60 mph and 1/4 mile acceleration times and those measured today using the Global Positioning System (GPS).
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.
Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.
Motorcycle drag racing (also known as "sprints") involves two participants lining up at a dragstrip with a signaled starting line. Upon the starting signal, the riders accelerate down a 1 ⁄ 4 mile (0.40 km) or 1 ⁄ 8 mile (0.20 km) long, two lane, straight paved track where their elapsed time and terminal speed are recorded.
Some drag strips are even shorter and run 660 feet, 201 m, or 1/8 mile. The 1,000 foot distance is now also popular with bracket racing, especially in meets where there are 1/8 mile cars and 1/4 mile cars racing together, and is used by the revived American Drag Racing League for its primary classes (not Jr Dragster).
Performance tests from 1977 estimated 0-60 mph (97 km/h) time for the Can Am with the Pontiac engine at about 10 seconds, about the same as the previous year's Le Mans with the 455, and a 1 ⁄ 4-mile (0.40 km) time of approximately 17 seconds. It is estimated that 1133 Can Ams were produced. [3]
The track is billed as the "World's Fastest Quarter Mile Oval." The current track record was set by Jeff Bloom in a 410 extreme winged sprint car on August 21, 2010 at a time of 9.908 seconds. [ 1 ] This is the first lap record under 10 seconds on a quarter mile oval track of any type, breaking Anderson Speedway 's 10.28 second lap record. [ 1 ]
