Horsepower Adjustments – From Competitor Requests
- Jul 7, 2014
- 2 min read
The NHRA Technical Department released Horsepower changes July 8, 2014 after review and evaluation of written requests from Lucas Oil Sportsman Series competitors. All changes are effective July 8, 2014. Only those requests received by May 31, 2014 were considered during this scheduled evaluation. Any requests received after May 31, 2014 will be reviewed during the next scheduled evaluation of 2014.
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 sent in writing to: National Hot Rod Association; Technical Department; attn: AHFS; P.O. Box 5555, Glendora, CA 91740; or e-mail, http://www.nhraracer.com/ahfs.asp. Requests for reviews must be received no later than November 18, 2014 to be included in the next scheduled horsepower and index review.
