Sao Paulo, Brazil (Betting Express) - Panther Racing chief executive officer and managing partner John Barnes landed himself into trouble with IndyCar for an inappropriate comment he posted on his Twitter account earlier this week.

IndyCar officials slapped Barnes with a $25,000 fine and placed him on probation for the remainder of the year on Saturday after tweeting "a comment using improper or disparaging language in reference to IndyCar."

Barnes criticized IndyCar for its recent decision to make modifications to the turbochargers on the cars. Chevrolet, which is a new engine supplier in the series this year, filed a protest on April 18. A three-person panel heard the protest on Thursday in Indianapolis and upheld IndyCar's approval of a 0.74 A/R compressor cover for the single turbocharger.

Shortly after the panel denied Chevrolet's protest, Barnes tweeted, "Today is the day to resolve TURBOGATE! I hope [indycar] gets their act together. It has been embarrassing."

Panther Racing is one of the teams utilizing the Chevrolet engine. J.R. Hildebrand drives the No. 4 entry for the team.

Following IndyCar's announcement of the penalty, Barnes released a statement.

"Nobody cares about open-wheel racing and the Indianapolis 500 more than I do, and therefore, I'm very passionate about all the decisions that are made - right or wrong - that affect our sport," Barnes said. "I'm not the first person who has disagreed with a sports league or sanctioning body's decision, and I certainly won't be the last to get fined for doing so.

"While my passion for this sport will never waver, I should have chosen a more private forum to voice my opinions. Even if we don't always agree, I respect the authority of the IndyCar Series and its officials and will continue to abide by their rules and regulations."

Barnes has the option to appeal IndyCar's penalty assessed to him.

The IZOD IndyCar Series is competing in Sao Paulo, Brazil this weekend. Will Power from Team Penske won the pole position for the 75-lap race on the streets of Sao Paulo. Penske also uses Chevrolet's engine.
