In the week's leading up to Homestead I saw a quote by GM's Joe Negri that Chevrolet had discovered an oil scavenge problem that had been remedied and had added 10 horsepower to the Indy Chevy. While obviously oil windage and scavenging issues are important to race engines this seemed a little strange somehow. Since the Chevy has been around awhile does this mean that the problem has been there all along but was just now discovered? Did something change in the oiling system since last season? Would the Chevrolets have found the extra 10 HP last season if they had been in competition with Honda and Toyota then instead of just Infiniti? Or is this just some kind of PR statement out of GM to address the new competitive reality of the IRL? Does anyone have any insight on this???
