Team Ireland made its debut in the 1991 NASCAR Winston Cup Series season, competing in four races with the No. 53 Chevrolet; the team intended to field IndyCar driver John Paul Jr. in its cars, but after Paul proved to have a hard time adjusting to the heavy NASCAR cars, he was replaced after two races by Bobby Hillin Jr., who joined the team for a planned 15-race schedule in 1992.[1] Changing to the No. 31 and using cars and engines supplied by Richard Childress Racing,[1] the team competed in ten races during the 1992 NASCAR Winston Cup Series season, posting a best finish of 13th in the Coca-Cola 600 at Charlotte Motor Speedway,[2] before being forced to close due to a lack of sponsorship;[3] the team was unable to pay a fine levied by NASCAR for the use of illegal cylinder heads in the Mello Yello 500 in October,[4] and team owner Birrane chose to leave the sport.[5]
