The new compressor cover helps to offset the performance disadvantage of the current IndyCar single turbo hardware as measured by INDYCAR's turbo supplier. This correction was designed and provided by the turbo supplier under the direction of IndyCar and was approved prior to the 2012 season.
We look forward to deploying the new compressor cover to optimize performance of the Honda Indy V-6, as we continue to do battle with our worthy adversaries from Lotus and General Motors.
04/27/12 “Chevrolet filed a protest as permitted by the IndyCar rules to an April 18th decision by IndyCar to allow a modification to the turbocharger used by another engine manufacturer. Chevrolet believed the modification was contrary to the applicable series rules, and asked IndyCar to thoroughly review the issue so that the rules were applied fairly. We respect the diligence of the panel appointed to hear the protest and examine the situation. While we are disappointed with today's decision, we are prepared to continue to compete at the highest level in the IZOD IndyCar Series." Jim Campbell, Chevy U.S. Vice President, Performance Vehicles and Motorsports
