The Slinger Super Speedway (also known as Slinger Speedway) is a quarter-mile paved oval automobile race track with 33-degree banked corners located in Slinger, Wisconsin. The track is billed as the "World's Fastest Quarter Mile Oval." The current track record was set by Jeff Bloom in a 410 extreme winged sprint car on August 21, 2010 at a time of 9.908 seconds. This is the first lap record under 10 seconds on a quarter mile oval track of any type, breaking Anderson Speedway's 10.28 second lap record. Bloom's lap eclipsed the track record set by USAC midget car driver Tracy Hines on May 17, 2008 at an elapsed time of 10.845 seconds. The lap was the fastest ever midget car lap on an asphalt quarter mile track. He eclipsed the long-standing mark of 11.095 seconds set by Tony Strupp's late model on June 12, 1994. Strupp's 31 year old record for Super Late models was broken By Steve Apel who ran the first ever sub 11 second super late model lap with a time of 10.994 on May 18, 2025
