Racers must make at least 12 passes to qualify for NHRA Power Rankings. For most, the reaction time of the driver to hit the gas and the car to move forward to break the stage beam usually takes around. You can see all 15 statistics that inform Power Rankings here. The class average is based on the best 60 percent of runs because drag racing is always a moving-target sport. Success rate: How often a racer gets to the track quicker than the class average. Incremental times: The average of a racer's incremental times (60-foot being one of those increments). All runs faster than 300 mph in nitro classes, 200 in Pro Stock and 180 in Pro Stock Motorcycle are included. Reaction time: Average of a racer's reaction times. All runs quicker than 3.9 seconds in Top Fuel, 4 seconds in Funny Car, 6.63 seconds in Pro Stock and 7 seconds in Pro Stock Motorcycle are included. These statistics are weighted against class averages to produce race-by-race ratings.Įlapsed time: Average of a racer's elapsed times. Power Rankings include six key categories to measure drag racing performance, including elapsed time, reaction time, top speed, incremental times, success rate and red light fouls.
