New Size In Effect For July 3 Event At Daytona International Speedway
DAYTONA BEACH, Fla. (June 7, 2010) – NASCAR has announced that NASCAR Sprint Cup Series teams will use carburetor restrictor-plate openings of 1 1/32 inches for the July 3 event at Daytona International Speedway. The previous plate at Daytona last February was 63/64-inch.
This equates to a .074 (square inch) area increase per opening for air intake.
Monday’s announcement pertains only to next month’s Coke Zero 400 Powered by Coca-Cola – the last NASCAR Sprint Cup Series event on the current Daytona asphalt. The 2.5-mile, high-banked superspeedway will be repaved prior to the 2011 Daytona 500.
