Denso Spark Plugs NHRA U.S. Nationals Super Stock and Stock Runs Excluded From Automatic Horsepower Factoring System

NHRA has announced that the Automatic Horsepower Factoring system will not be used during this year’s DENSO Spark Plugs NHRA U.S. Nationals. As a result, runs made by Super Stock and Stock competitors at any time during the event will not count towards class averages, nor will they be used to trigger index or horsepower adjustments.

 

This decision was reached as the result of competitor requests and multiple conversations with members of the Stock and Super Stock Sportsman Racer’s Advisory Council (SRAC). During those discussions, a significant number of competitors expressed the desire to show the full performance potential of their cars during NHRA’s most prestigious event without fear of future horsepower and/or index penalties.

 

The AFHS will remain in effect for all other NHRA Mello Yello Series national and Lucas Oil Series divisional events.
