NHRA announced the most sweeping changes to its Pro Stock division since 1982 when it abandoned the pounds per cubic inch format. In a two-phase movement, NHRA announced technical and procedure changes to the factory hot rods aimed at making the class more fan appealing. .

The first phase of the changes focuses on fan appeal and will be implemented at next weekend's NHRA Sonoma Nationals in Sonoma, Ca.            

The three changes that are effective at Sonoma are designed to increase spectator appeal and enhance the overall pit experience for fans.

NHRA has mandated teams must back their cars into the pit spaces with the engines uncovered for better visibility to the fans. Crewmembers are no longer allowed to touch the cars during the burnouts.  NHRA will make it mandatory for teams to create automobile manufacturer identification headers visible on the racecars’ windshields up to a maximum of 4.5-inches high, but not smaller than 4.25-inches.

On January 1, 2016, Pro Stock teams will be required to equip their cars with electronically-controlled throttle body fuel injection systems, making engines more relevant from a technology standpoint. To reduce and control costs for the race teams, an NHRA-controlled 10,500 Rev Limiter will be added to the fuel injection systems.

Additionally, NHRA also will require Pro Stock teams to remove all hood scoops and reduce the length of the wheelie bars to a length specified by the NHRA Tech Department. Those changes are designed to make the racecar designs more relevant and to boost spectator appeal by increasing the unpredictability of the class through more “wheels up” launches from the starting line.
              
NHRA promises to work with new television partner FOX Sports to improve coverage and maximize exposure of the Pro Stock category through increased driver and team profiles and technical features, in addition to expanded on-track racing coverage.                      

“Pro Stock racing has a tremendous history with NHRA and proves each weekend by the close side-by-side finishes that it is one of the most competitive forms of racing in all of motorsports,” said Peter Clifford, NHRA president. “Through these changes we hope to provide a platform so the Pro Stock class can evolve from a technological standpoint, yet reconnect with its roots by generating more interest and appeal among spectators.”
