Irwindale Speedway "King of the Wing" - For the first time since its opening in 1999, the Irwindale Event Center hosted the "King of the Wing" Sprint Car Challenge, and these 750-900 horsepower - 1600 pound monsters did not disappoint. The track record was shattered in the first qualifying session by JoJo Hilbert with a 13.971. Hilbert went on to win the main event after some confusion in scoring when the caution laps were counted in error. Race officials ultimately call the cars back on the track to rerun the final 12 laps.
