2009 end of year Stock, Super Stock horsepower adjustments announced
12/16/2009


The following Stock/Super Stock horsepower changes were released December 16, 2009 produced by the Automatic Horsepower Factoring System (AHFS). This is the second of two scheduled horsepower adjustments for this year. All changes are effective January 1, 2010. It should be noted that these changes include only results produced by the AHFS, and do not include written letters or requests. Those changes are listed separately.
The AHFS is a program based on actual run data compiled from all available runs at NHRA national events only. The data-based format provides the ability to calculate average performances for any class and/or engine combination in Stock and Super Stock. The trigger point for the system is 1.15-second or more under the respective index, and must be produced twice during the review period. 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 1.40 and under run is recorded during any NHRA event.

What this means to me is that my Challenger is now rated at 390 HP not the 385. This also means The min weight is now 3290 not 3250. Plus with the index being lowered .3 this will make it tougher next year....
