With the help of sponsor Provimi Veal, Luyendyk ran his first full Champ Car season in 1985, winning the rookie of the year title both for the season and the Indianapolis 500. 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 won the 1990 Indianapolis 500 for Doug Shierson Racing. His average speed record, which stood for 23 years, was finally broken in the 2013 97th Indianapolis 500 by Tony Kanaan with an average speed of 187.433 mph (301.644 km/h).
