Horsepower Adjustments – From Competitor Requests
- Dec 18, 2014
- 5 min read
The NHRA Technical Department released Horsepower changes December 19, 2014 after review and evaluation of written requests from Lucas Oil Sportsman Series competitors. All changes are effective January 1, 2015. Only those requests received by November 18, 2014 were considered during this scheduled evaluation. Any requests received after November 18, 2014 will be reviewed during the next scheduled evaluation of 2015.
Letter review is part of NHRA's commitment to evaluating input from the Sportsman racing community and is an important element of NHRA's Automatic Horsepower Factoring System. “No Change” combinations are listed so that competitors may see that requests were reviewed by the Technical Department, even though the request resulted in no change.
Requests for horsepower changes or reviews can be made here www.nhraracer.com/ahfs.asp. Requests for reviews must be received no later than May 31, 2015 to be included in the next scheduled horsepower and index review.
