In drag racing, a transbrake is a mechanism that selectively places the transmission in a forward and reverse gear simultaneously. This allows the engine to create full power without transmitting that power through the driveline, allowing the car to stay in one place.
The delay box acts as an on-board timer for the transbrake (from transmission brake). A transbrake is a part of a racing automatic transmission used in drag racing, and are not found in manual transmissions. The electronic timer is packaged in a metal enclosure when sold to drag racers, thus the slang term delay box.

Launch control operates by using an electronic accelerator and a computer program in a drive-by-wire application, and through fuel or spark cut in a mechanical throttle application. The software can control acceleration based on engine specifications to make the car accelerate smoothly and as fast as possible, avoiding spinning of the drive ...
