What is Drag Racing?
Simply explained, drag racing is an acceleration contest from a standing start between two race cars over either a quarter-mile or an eighth-mile measured distance. The race is started by electronic timing equipment which we call a 'Christmas Tree.'
When leaving the start line, each car breaks a light beam which activates a timer. At the finish line the car breaks another light beam which stops the timer, giving very accurate elapsed times and speeds over the measure distance.
The 'Christmas Tree'
The 'Christmas Tree' is on the startline of the race track. It is a very important piece of equipment which controls the race.
As a vehicle approaches the starting line it breaks the first light beam and the 'Pre-Stage' light on 'Christmas Tree' is lit. The driver slowly inches the car forward until the second light beam is broken and the 'Staged' lights come on.
After both cars are staged the Starter activates the 'Christmas Tree' and three amber lights and one green are sequenced. Drivers use amber lights as a guide to anticipate the green bulb coming on. Leave too soon and a bright red "foul" shows. See Christmas Tree above.
This is probably the most common form of drag racing. If you are a first time spectator at a drag race event it is a little more difficult to understand but you soon get used to the system.
E.T. Bracket Racing is a handicapped race between two race cars usually of varying performance, for example, one car may be able to cover the distance in 10 seconds and the other in 11. The elapsed times for each vehicle is compared and automatically adjusted so that the slower car receives a headstart equal to the difference in time of the two. In theory, both race cars should end up at the finish line together.
With this system, virtually any two race cars can be paired in a competitive drag race without one having an advantage over the other.
Heads Up Racing.
Heads up racing is a contest between two race cars. Both drivers leave the startline at the same time and the first to the finish line wins the race.
