One of the guys I work with stated he would like to know what the horse power of a Indy car engine is. Key word search "indy engine" did get me some info, but it is outdated. What are the numbers on the 2006 Indy car engines? What I found was 2003 Chevy Indy V8 is 3.5 liter (214 ci). Produces 675 pluss horsepower and weighs 280 lb. . $120,000. Max. 10,300 rmp (10,700 rpm in 2002). Methanol fuel. Sustained high speed operation.
