Round four of NOS Energy Mayhem @ the MAX Presented by Kooks Custom Headers, JE Pistons and Roush Yates Performance Parts took place Saturday at zMAX Dragway with many of the winners making their way back to victory lane for the second and third times this season.

The five-round championship series features Super Pro, Pro Street, Top Eliminator, Sportsman, Motorcycles and two divisions of Junior Dragsters.

Ed Pauley, of Shelby, N.C., earned his second Top Eliminator win this season in as many trips to the Bellagio of drag strips. Pauley had an elapsed time of 6.377 at 105.61 mph in his 1968 Camaro. Just like they did in round three, the Pauley family celebrated in victory lane together.

“I love racing here. This place is nice, parking is great, and the facilities are of course top notch. The surface is great,” Pauley said of his love for zMAX Dragway. “They do a great job putting these races on. I’ve told everybody I know that they need to be here racing.”

Scottie Keller, of Mooresville, N.C., was fastest in the Motorcycle class for the third time in 2012, winning with an elapsed time of 9.634 at 135.27 mph in a final against his teammate Daniel Come.

“Everything went really well,” Keller said of his run. “We come as a team and just him and I made it to the finals. So I consider it a win on both ends. This is one of the best drag strips to come to around here. I like zMAX a lot and we will be back.”

For the second time this season, Pawleys Island, S.C., native Azarias Gouin took the win in the Junior Dragsters A division. Gouin had an elapsed time of 9.015 at 73.65 mph. Joe Foley, of Statesville, N.C., also made his second trip to victory lane this season in the Junior Dragster B division with an elapsed time of 7.863 at 83.82 mph.

William Roberts, of Davidson, N.C., was a first-time winner this season in the Super Pro class. Roberts’ 2000 Race Tech Dragster thundered down the track at 134.79 mph and finished with an elapsed time of 9.616 seconds.

“The car ran really well,” Roberts explained. “The track conditions gave us fits because trying to find a set-up that would actually go down a hot race track was really tough. Fortunately in this case, old age and treachery triumphed over youth and enthusiasm.”

First-time winners from round four of Mayhem @ the MAX also included Chris Yates and John Taylor. Yates and his 1974 Pontiac took the win in the Pro Street division with an elapsed time of 11.111 at 112.51 mph. Taylor won the Sportsman division in his 1991 Camaro, going 86.80 mph and garnering an elapsed time of 7.995 seconds.

Each class has separate eligibility requirements and entry fees. Points will be tallied after each event and champions in each category will be crowned.
