Past success at zMax Dragway meant little Sunday at the National Hot Rod Association’s O’Reilly Nationals.

Courtney Force had just lost in the second round of Funny Car eliminations last Sunday at the National Hot Rod Association’s Mac Tools U.S. Nationals in Indianapolis.

Tim Wilkerson barely qualified for the National Hot Rod Association’s Countdown to the Championship. Now he’s trying to make the most of his spot in the Funny Car postseason.

The weather is cooling, which coincides nicely with the start of the NHRA’s Countdown to the Championship this weekend at the O’Reilly Nationals at Concord’s zMax Dragway.

The National Hot Rod Association’s Countdown to the Championship has arrived and it gets underway this weekend with the O’Reilly Nationals at Concord’s zMax Dragway.

There’s no hotter driver on the National Hot Rod Association’s Full Throttle series than Erica Enders. Entering this weekend’s rain-postponed Mac Tools U.S. Nationals in Indianapolis, Enders had won three of six events in the NHRA’s Pro Stock car division.

The annual Summer Shootout Series will go out with a bang Tuesday night at Charlotte Motor Speedway with fireworks and appearances by NASCAR Sprint Cup Series driver and former Legend Car racer Kyle Busch, as well as NHRA driver and B.R.A.K.E.S. founder Doug Herbert.

Erica Enders became to the first female driver to win an NHRA Pro Stock race, beating four-time series champion Greg Anderson on Sunday in the final of the Route 66 NHRA Nationals.
