Honda will be allowed to make changes to the turbochargers on its IndyCar engines.
“We are gratified that an independent panel has endorsed IndyCar’s ruling,” said Honda in a statement following announcement of the decision.
There were many – at least eight – hours of discussion and deliberation by a three-man panel, the trio elected to uphold INDYCAR’s decision to allow the 0.74 A/R compressor cover for HPD’s engine–replacing the original 0.57 A/R compressor cover that Borg Warner placed on the turbocharger in its initial configuration.
Chevrolet had objected to Honda, which unlike its rival engine manufacturers using a single-turbo rather than twin layout, being given permission to introduce a new housing from this weekend’s Sao Paulo street race.
The ruling was announced earlier than anticipated to give teams time to make the modification.
IndyCar allowed the change because it felt an agreement had been reached in early engine meetings in 2010.
