Allen Johnson raced to victory in the K&N Horsepower Challenge, the special Pro Stock bonus event, Saturday at the SummitRacing.com NHRA Nationals.

In other racing action at The Strip at Las Vegas Motor Speedway, Antron Brown (Top Fuel), Robert Hight (Funny Car) and Mike Edwards (Pro Stock) earned No. 1 qualifying positions in their respective categories at the NHRA Mello Yello Drag Racing Series event.

Veteran Pro Stock driver Johnson claimed his second victory in the K&N Horsepower Challenge by holding off Erica Enders-Stevens in the final round. Johnson, who earned $50,000 for the victory, also defeated Greg Anderson and teammate Jeg Coughlin in earlier rounds.

"We got it done today," Johnson said. "It was a lot of fun. Any time you can stack up against the eight drivers that was in that thing, just to be there is an honor, and to beat them is an even bigger honor."

In Top Fuel, Brown remained on top of the field in his dragster. Brown's Friday performance of 3.780 at 320.43 gave him his first No. 1 qualifying position of the season and 33rd of his career. He will face fellow competitor Brandon Bernstein in the first round of eliminations.

Hight scored his first No. 1 position in the Funny Car class in more than 19 races with his Friday run of 4.053 at 315.19 in a Ford Mustang. Hight will open eliminations against Jeff Arend.

Edwards powered his Chevy Camaro down the track with a performance of 6.642 at 208.26 to claim his fourth consecutive No. 1 qualifying position of the season in Pro Stock. It was the 45th top qualifying effort for Edwards, who will face Larry Morgan in the opening round of eliminations.
