NHRA Tech Department Announces 2019 Mid Year Stock, Super Stock Horsepower Adjustments
Image
The National Hot Rod Association (NHRA) Technical Department has announced mid-year horsepower changes to the Stock and Super Stock categories.
The announcement is the first of two scheduled horsepower adjustments for this year. The changes were produced by the Automatic Horsepower Factoring System (AHFS).
The AHFS is a program based on actual run data compiled from all available runs at NHRA events. The data-based format provides the ability to calculate average performances for any class and engine combination in Stock and Super Stock.
The trigger point for the system is 1.00-second or more under the respective index and must be produced on two different occasions. Engine-combination averages and class averages are then computed and analyzed to determine if a change is warranted.
The amount of change is calculated on a stepped percentage basis. Where applicable, adjustments will be effective for the specific car model or body style being evaluated. An automatic adjustment is instituted outside the two-time a year process when a 1.20 and under run is recorded during any NHRA event.

In other NHRA news, tickets for the 2020 season-opening 60th annual Lucas Oil NHRA Winternationals presented by ProtectTheHarvest.com at Auto Club Raceway at Pomona are on sale now for the national event taking place Feb 6-9, 2020.
