Sometimes, winning is in the family.

At the Pinewood Derby World Championship in Times Square on Saturday, brothers Alex and Brian Gulnac were looking to replicate their one-two punch from last year’s event.

Alex, 8, sporting a pink and blue mohawk, came in first last year, and Brian, 11, second.

The Warren, Pa., siblings took part in the derby’s Pro Stock Division.

“I like Pro Stock because it’s more fun. Most of the Pro Stock cars are better than the normal cars,” Brian said.

Over 250 Scouts from 20 states arrived in the Big Apple to participate in the competition, where they raced their handmade cars on a 45-foot custom track at speeds of up to 40 mph.

“How many times as a nine- or 10-year-old do you get to race in Times Square?” said Ricky Mason, president of the Greater New York Council of the Boy Scouts.

“It’s an example of Scouting. You really learn something while having fun at the same time,” he said.

Eight-year-old Lerrod Smalls was back for the second time.

“I didn’t win last year, but I believe I’m going to win this year,” said Lerrod, whose dad even made a test track for him at their home in Brooklyn.

“You have to make sure there’s no friction. When there’s not a lot of friction, the car goes fast,” Lerrod said.
