E.T. Bracket Racing is the most popular type of drag racing

In this form of drag racing, two vehicles with different performance potential compete against each other but on the fairest possible basis. The idea behind the rules of bracket racing is to characterize the continuous performance of a driver and his vehicle, not just pure speed. With these requirements, the victory should go to the driver, who is able to accurately predict his time, whether it is fast or slow. Thus, a victory is less dependent on large spending of money but rather on the skill.

Extensive modifications are allowed in the two most widely used classes ProET and Super ProET. Vehicles that drive the quarter mile between 9.00 and 11.99 sec. start in the Pro ET class. The Super Pro ET class is designed for faster vehicles requiring 6.00 to 8.99 sec. for the quarter mile. In contrast to the Super Gas and Super Comp classes, here each participant determines his own personal index, which must be forwarded to the timekeeper before the race runs. In addition, time-delayed starts are at the elimination runs (elimination). This means that the slower opponent at the start lights gets the time difference between the two indices as a lead. If both opponents drive the quarter mile with exactly their index time, they would have to drive across the finish line at the same time, but the reaction time often determines the victory. Underbidding your own index (break-out) leads to disqualification in the elimination run.

An example from ET Bracket Racing: Vehicle X has run the following times on the quarter mile: 11.68, 11.64 and 11.66 seconds and the driver estimates that a dial-in of 11.65 seconds is appropriate. Vehicle Y has run the following times on the quarter mile: 10.17, 10.12 and 10.16 sec. and the driver chooses a dial-in of 10.15 sec. Consequently, vehicle X will get a 1.5 second advantage over vehicle Y. If both vehicles drive the quarter mile exactly the time they have estimated, the victory will go to the driver who reacted the fastest at the starting lights (RT = reaction time) It means, also drives first across the finish line. Both lanes are measured independently of each other and the time starts to count only when a vehicle starts to move. This sometimes makes it seem like a vehicle has a mathematical advantage over the measured time, but actually loses the race. This fact makes the R.T. at the start line extremely important in drag racing!

Dial-In Index A "dial-in index" is the estimated time the driver needs with his vehicle to get from the start line to the finish line. The time estimated by the driver is clearly legible at the window of his vehicle or we record the time beforehand and give it to the timing crew in time so that the persons operating the timekeeping system set the correct start sequence at the start tree. The slower vehicle thereby receives a lead, which is also the difference of the dial-in's of the two vehicles (as described above in Bracket Racing). If one of the vehicles drives faster than its dial-in, it is called a "break-out" and will be disqualified. But if both vehicles drive faster than your dial-in and both drive a break-out, the one who drove the least under his dial-in will be the winner. This method offsets the benefit of having someone slow down dial-in to gain a head start. During a race you can change the dial-in time as often as you like, as long as the organizers allow it.


A driver may be disqualified for one of the following reasons: 1.If he starts too early from the starting line (red light). 2.If he leaves the lane marking. Either by crossing the center line, touching the guardrail or by approaching a route device such as light barriers or similar. 3.If he does not staged 4.If you fail or pass a scheduled inspection (in NHRA class races, vehicles are weighed, fuel is examined after each run and event winners can even perform a complete engine disassembly). 5. In case of a double disqualification - e.g. a driver lays an early start but the other driver crosses the lane marking while driving on the other driver's lane, the driver wins with the lesser offense, that is, the early start.
