Marvin Benoit admits the lines sometimes get blurred.

Benoit, the founder of Quick Fuel Technology, a leading manufacturer of carburetors, loves to drag race but wonders sometimes if he's doing it for product development or because he enjoys the challenge of racing.

"It's always fun to be out here racing, and with you friends in Indy," said Benoit.

Benoit has five cars in competition this weekend, and he's racing two of them.

One of the two cars he's driving, a 27 T Roadster nicknamed "Baby" was debuted at the NHRA U.S. Nationals 25 years ago.

"Still the original paint," Benoit boasted, pointing to the roadster painted in the QFT red, white and black company colors.

Benoit founded QFT 18 years ago when he found himself on the outside of a Holley downsizing. The parent company of Holley, HPI, purchased QFT in 2012.

Understanding what makes carburetors work better is what intrigues Benoit.

"I guess I am out here, learning how to make our product better yet still trying to win races," Benoit said. "The racing is part of your lifestyle, and in there it all incorporates work. You can combine your passions, racing and making your product better."
