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.
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.
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).
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.
As with land-based drag racing, competitors race their vehicles for the lowest elapsed time (low ET) over a straight race course of a defined length. There are three standard drag race course lengths, 660 feet (1/8 mile), 1,320 foot (1/4 mile), and the most common length, used in professional drag boat racing, 1,000 feet (3/16 mile plus 10 feet).
Drivers 14-20 can race in Jr. Comp, where racers are limited to 6.900 at 109.99 MPH. Drivers who are 9 as of January 1 can participate in either the 8-9 or 10-12 category once they turn 10 during the year, and drivers who are 12 as of January 1 can participate in the 10-12 or 13-17 category once they turn 13 during the year.
[1] The speedway featured banked, paved 1 ⁄ 2 - and 1 ⁄ 3-mile oval tracks and a 1 ⁄ 8-mile drag strip. The property was primarily used for NASCAR races such as ARCA Menards Series West and Whelen All-American Series events. In late 2011, NASCAR announced it was dropping Toyota Speedway from its schedule.
'Rollout' is the distance travelled by a vehicle before the timing lights on a drag strip are triggered. … can affect the final run time by up to 0.3 of a second. … important to discount this first foot of movement from the final run time, to ensure that the run time captured by the GPS data logger is as close as possible to the official ...
