A ial-in time is a term used in drag racing to claim how fast a racer's car is. Dial-in times function to determine which cars race against each other. If one car's dial-in time is significantly slower than another's, the slower car is given a handicap (which is done in E.T. bracket racing). The purpose of dial-in times is to make the race fair - so if a racer beats his or her dial-in time, he or she is automatically disqualified. Dial-in times can, however, be manipulated to be significantly slower than the car actually performs, in a technique called sandbagging.
