IndyCar rules in favor of Honda, against Chevy, in turbocharger dispute
A three-man panel was selected to hear Chevy's appeal, and their verdict in favor of Honda means that the Japanese automaker was permitted to swap the shroud before this weekend's São Paulo race. The new shroud is said to be worth 10 to 15 more horsepower, but in the end, Chevrolet-powered racers managed to finish in seven of the top 10 positions.
Chevy had been contesting the ability to make an engine change at this point in the season, when there are no constant-parity clauses in the regulations and IndyCar has an agreed date in mid-June for such alterations to create parity. Honda's argument was that an agreement in 2010 that was meant to prevent turbo wars does allow the change it sought to make. The panel supported Honda's interpretation of the parity argument.
Chevy has said it will not appeal the decision. Now it's up to the Honda-powered drivers fitted with the new 0.74 A/R compressor cover to show they can do better than second place.
