"3/7/2018

As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the Phoenix and Belle Rose events, the following changes have been made.

The horsepower rating for 73-74 Pontiac Trans Am, entries with the 455 cubic inch engine and a factory rating of 250 currently rated at 321, has been decreased by eleven horsepower, to 310 horsepower; for Super Stock Eliminator.

NHRA's 2018 Automatic Horsepower Factoring System outlines that any run of 1.20-seconds or more under the index will receive an immediate index decrease or horsepower increase. These changes are effective March 7, 2018."

So you can get a 11 HP DECREASE under AHFS now by running fast?? What?
