[1][2] Luyendyk won a total of seven Indy car races, including three in the CART series, all of them on ovals.

Gaining additional sponsorship from Domino's Pizza (and changing his racing number to 30, as at the time Domino's guaranteed customers that delivery orders would arrive in 30 minutes or less), his first win in the series came five years later in 1990, at the most important race in the series, with a record average speed of 185.981 mph (299.307 km/h).

Luyendyk continued to perform well at Indianapolis, scoring pole positions in 1993, 1997 and 1999, and retiring from the race while leading on three occasions.

[4] At the 1997 True Value 500 at Texas, a scoring error by the USAC resulted in Billy Boat being declared the race winner.

After 1998, Luyendyk decided to cut down to a part-time schedule, only racing in the 1999 Indianapolis 500 where he won the pole and dropped out because of a crash.

He retired from racing after the 1999 season, and for a short time, joined ABC Sports as a color commentator.

In 2016, Luyendyk was selected as a chief steward for the IndyCar Series alongside fellow racer Max Papis and Dan Davis.
