Top Fuel champ Antron Brown slides into Ed Carpenter's pole-winning IndyCar at Indianapolis

Antron Brown joked that he wouldn't mind making a couple of left-handed turns the next time he's on the track. Ed Carpenter thought it'd be fun to ramp up the speed by about 100 mph.

Maybe they ought to swap rides.

Brown, the reigning Top Fuel champion, stopped by his old pal's garage at Indianapolis Motor Speedway on Wednesday, slipping into Carpenter's No. 20 Chevrolet and getting a quick lesson in paddle shifting on the car that will sit on the pole for the Indy 500.

The two drivers from far different disciplines have known each other for about 15 years, Carpenter said. So after he posted a four-lap average of 228.762 mph to lead the field for Sunday's race, Brown decided it was time to swing by on his day off for an afternoon chat.

"It's just good times to come out," he said.
