Break-out/b] When a car runs quicker than its dial-in. The driver loses the race unless the other car breaks out by more, red lights, or crosses the center.
Christmas Tree/b] Composed of a two sets of staging lights, three amber lights, a green light, and red light. Used to stage a car and start the race.
Deep Staging/b] Utilized by experienced racers, it puts the vehicle closer to the finish line, decreases the racers reaction time, increases elapsed time and reduces the final trap speed, putting him/her closer to disqualification.
Delay Box (Box)/b] Is an electronic device used to aid the driver at the starting line. The driver can dial a number into the box called the delay. Used in conjunction with a transmission brake and a two-step, the driver holds down a button mounted on his/her steering wheel, activating the transbrake and two step, and then lets go of the button the instant he sees the of amber from the first bulb. The delay box will then count the thousandths of a second dictated by the driver and release the transbrake and two-step.
Dial In/b] Anticipated E.T. a vehicle will run.
Elapsed Time (ET)/b] The time between when the car starts and reaches the end of the 1/4 mile.
Line-lock/b] Allows the driver to apply the brakes on one set of tires by hitting a button. Based on your drivetrain configuration, the linelock will be applied to the wheels that are not driven. Four-wheel line-locks are used to simulate a transbrake.
Pro Tree/b] Three ambers illuminate on the Christmas tree at the same instant with the green illuminating .4 seconds later.
Reaction Time (R/T)/b] The delay that occurs when the last yellow light is turned on and the car clears the stage beam. The green light is turned on .5 seconds in a sportsman tree and .4 on Pro tree after the last yellow is lit up, therefore a R/T value of .5 or .4 is a perfect light.
Red-light/b] A red-light occurs if a car leaves the line before the green light comes on. During competition, this will immediately give the win to the opponent, unless the opponents crosses the center line.
[b]Sandbagging/b] This is the practice of dialing-in an ET that is much slower than the ET that a car runs so that the vehicle should always hit the finish line first.
[b]Shallow Staging/b] is utilized by beginners because it puts the racer further away from the finish line thereby increases reaction time, reduces elapsed time and increases trap speed.
[b]Time Trials/b] A limited amount of passes prior to qualifying or the actual race.
[b]Transbrake/b] A device that allows a car to remain stationary even when the motor is under power. Working only on an automatic transmission it places first gear and reverse at the same time. With gears of the same ratio but in the opposite direction the car will not move. Upon pressing a button, the reverse gear is released allowing for a powerful launch.
[b]Trap Speed/b] Refers to a car's MPH measured during the last 60 feet of the 1/4-mile. Taking the weight of a car and the trap speed makes for a good indicator of how much horsepower an engine has.
/b] When a car runs quicker than its dial-in. The driver loses the race unless the other car breaks out by more, red lights, or crosses the center.
