'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 ...
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.
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).
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.
In bracket drag racing and short track motor racing when a racer has a dial-in time / qualifying speed much slower than the car can actually perform. The term can also be used to describe a fast driver who holds back during a race until just before the end, when they suddenly pass up through the field to win the event.
Super Comp (or Quick Rod) is the fastest of the heads-up Super classes (8.90 index).Super Comp is composed primarily of dragsters.Engine, chassis and body modifications are virtually unlimited, though all entries must adhere to NHRA or IHRA safety standards.
NASCAR had been fairly adamant the rules package would remain unchanged but reversed course late last season when it was evident the racing clearly had suffered at smaller tracks.
Two Top Fuel dragsters side by side during an NHRA event in 2012. Top Fuel is a type of drag racing whose 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 341.68 miles per hour (549.9 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.61 seconds.
