DAYTONA BEACH, Fla. -- NASCAR hopeful Danica Patrick's stock car debut at Daytona International Speedway was cut to four laps Friday when rain delayed, then wiped out, the first session of a three-day ARCA Series test.

Patrick's No. 88 JR Motorsports Chevrolet was one of 26 cars that got on the race track beginning about 1:38 p.m. ET. Patrick left pit road about 1:56 and said she was flat-out all the way around the track on her third lap.

Patrick's best lap was her fourth -- 51.095 seconds, an average speed of 176.108 mph -- as she began preparation for her stock-car debut on Feb. 6. That lap would not have qualified in 2009.

ARCA veteran Mikey Kile was fastest Friday on the last lap of his three-lap run, in 49.804 seconds, an average of 180.708 mph in a No. 25 Venturini Motorsports Toyota. Justin Lofton, the 2009 ARCA champion, won the pole for last year's ARCA Speedweeks opener with a lap in 49.418 seconds, 182.120 mph.

Patrick had previously raced at Daytona, in the 2006 and 2009 Rolex 24s and tested an Indy car here in 2007, a speedway spokesman said.

"I'd driven Turns 2, 3 and 4, but not at speed, in the sports car in the 24 hours," Patrick said. "So I knew it was going to be a bit bumpy. I built up speed up high for two laps, I guess, and then I dropped down low and was flat-out around the bottom-ish.

"I think I could have been lower, but the car has a little bit we need to work on. I didn't realize it was two-and-a-half miles -- I guess I'm not an attentive race car driver -- but it's definitely the biggest track I've been on in a stock car. I've only been on a mile before and it was a big difference in how much the car moves around quite a bit."

When Patrick got out of the car she quickly debriefed with one of her engineers, then met with crew chief Tony Eury Jr. Her face, hand motions and body language were all vividly expressive of how the car was far from stuck to the road as an Indy car might be.

"The car was definitely getting some action in the rear over the bumps and it was getting a little bit loose," Patrick said. "But I kept my foot in it and I tried not to chase it too much with the steering, because I didn't want to have an accident. But it felt all right, and it was fun. I trusted the car and the preparation of it and the set-up Tony and the guys put under it."

Patrick was one of 10 women drivers scheduled to be at the test. Four of them got on track Friday and local Daytona Beach driver Alli Owens, a veteran of parts of two ARCA seasons, had the best woman's lap -- 50.375 seconds, 178.660 mph -- in a No. 15 Venturini Motorsports Chevrolet. (Continued)
