Perhaps the most hotly contended racing class at O'Reilly Auto Parts Friday Night Drags is the Zaxby's Street Outlaw Division. It's one of just a handful of divisions that allows the use of nitrous oxide or "nitrous," which enables engines to burn more fuel by providing more oxygen than the air alone. The result: a more powerful combustion, faster cars and a fan-favorite division on Friday nights.

Charles Street, who fittingly lives up to his surname, drives a 1985 Mustang GT in the division and packs the extra punch of nitrous. While he trails in the division points standings heading into Week 13, it's not for lack of a fast car.

"It's actually the most competitive I've seen it in probably two or three years," Street said. "I like running Street Outlaw; I like the people in the class. It's gotten to where it's very competitive now. You've got turbos, nitrous, all motor. You name it, it's in this class."

Despite a 14-point deficit in the standings, Street's confidence so far hasn't taken a hit.

"I think we're doing pretty good," he said. "Two weeks ago, we went to the semi-finals on it. It was popping a little bit towards the end, and it cost us a race. We got beat by about half of a fender."

Street has made some tweaks to his Mustang since his semi-final race appearance in Week 10 in hopes of being a little more competitive in the remaining six weeks of the season.

"We actually changed the rear-end gear out," he explained. "Transmission is the same as it was last year; motor's been completely gone through again. We tore up a few pistons on the first night out here and got the motor back. Now we're just working with some tuning issues."

Street will be chasing division-leader Lamar Chambers of Griffin and his 1985 Chevrolet S-10, who has racked 19 points through the first 12 weeks of the season.

In all, eight of 18 drag racing divisions are separated by three or fewer points heading into Week 13, including the ultra-competitive Harbin's Mechanical Services Super Pro, Summit Racing Equipment Sportsman and Factory Street divisions.

Street and the rest of the O'Reilly Auto Parts Friday Night Drags drivers hit the pit lane drag strip at Atlanta Motor Speedway for Week 13 this Friday, July 24 in one of the largest, street-style drag racing series in the nation.
