shipped one of the Ilmor Chevrolet V-8 engines over to the Alfa-Romeo engine developers in Italy, who in turn, tore the engine down to examine it and allegedly stole design ideas. It was returned in pieces and infuriated Ilmor officials. At the conclusion of the 1991 season, Danny Sullivan left the team, and was replaced by Bobby Rahal. Sullivan went to Rahal's old seat at Galles-Kraco Racing. Patrick's contractual obligations with Alfa-Romeo had ended, so the team attempted to re-sign with Ilmor, or possibly acquire older Ilmor engines from Newman/Haas. Due to the possible fraudulent actions by Patrick against Ilmor, the team was refused an Ilmor Chevrolet engine lease, despite inking the popular Rahal. Facing a decidedly uncompetitive powerplant situation for 1992, and escalating legal problems, in December 1991, Patrick sold the team outright to Bobby Rahal and his partner Carl Hogan. They formed Rahal-Hogan Racing, which is now known as Rahal Letterman Lanigan Racing. Third stint In the mid-1990s, Patrick began to rebuild his team from scratch. In 1994, Patrick formed a testing team for Firestone tires, spearheading Firestone's return to Indy car racing. They did not enter any races in 1994, instead operated all year as a non-competing factory test outfit. Scott Pruett signed on as the driver. In 1995, they returned full time to CART competition, as the Firestone works team. A few other smaller teams ran Firestones as well. Pruett won the 1995 Marlboro 500, had three other podium finishes, and placed 7th in points. In the next few years, Patrick experienced moderate success in CART. Pruett also won the 1997 Surfers Paradise event. After the 1999 season, Goodyear tires dropped out of Indy car racing. Firestone effectively became the exclusive tire supplier for both CART and IRL. As of 2023, Firestone continues to maintain that distinction in IndyCar. Due to money issues and the constant uncertainty of racing in Champ Car, Patrick Racing jumped over the IRL in 2004. They ran Al Unser Jr. until his mid-season retirement and then Jeff Simmons, Jaques Lazier, and Tomáš Enge. With no sponsorship for 2005, the team ceased operations and the assets were put up for sale.
