Ilmor-Chevrolet 265-A engine

The Ilmor 265-A is a turbocharged 2.65 litre V8 engine built for Indy car racing in the CART PPG Indy Car World Series between 1986 and 1993. It was designed and developed by Ilmor, the independent British engine firm founded in 1983 by Mario Illien and Paul Morgan, who left Cosworth after disagreeing about how its DFX Indy engine should be developed. Backed by team owner Roger Penske, the engine debuted in 1986 badged as the Ilmor-Chevy Indy V8 and was later badged as the Chevrolet Indy V8, the name under which Rick Mears won the 1988 Indianapolis 500. From 1987 to 1991 it won 64 of 78 CART races. The 265-B followed in 1992, the 265-C in 1993 and the 265-D and 265-E in 1994, and Chevrolet dropped its badging support after the 1993 season. It powered chassis from Lola, March, Penske, Truesports, Galmer and Rahal-Hogan.
