Delay Box

Delay Box

"Delay Box" is a common slang term used in drag racing to describe an on-board timer which is a Transmission Brake Delay Timer. A transbrake forces the race car to remain stationary at the starting line, in gear, regardless of how much engine power is applied. When the visual signal is given to start the race, the driver triggers the delay box to begin timing (precisely counting down). If the driver does not interrupt this timing device, the car is launched down the race track at the instant the timer expires (counts to zero). Delay box use was very controversial in the 1980s and 1990s, as it removed a portion of the advantages more experienced racers had. There was a period where technologists added and concealed homemade circuitry inside a delay box that violated some racing associations rules. Racing associations have imposed strict limits on delay boxes today, with manufacturers having to submit to an approval process, which has drastically reduced the number of makers of these devices.

Famous quotes containing the words box and/or delay:

    The distant box is open. A sound of grain
    Poured over the floor in some eagerness we
    Rise with the night let out of the box of wind.
    John Ashbery (b. 1927)

    Once we began to see our images
    Reflected in the mud and even dust,
    ‘Twas disillusion upon disillusion.
    We were lost piecemeal to the animals,
    Like people thrown out to delay the wolves.
    Nothing but fallibility was left us....
    Robert Frost (1874–1963)
