NASCAR moves to limit tandem racing

NASCAR has announced technical changes ahead of next month's Chase race at Talladega in an attempt to limit the tandem racing that has prevailed this year at restrictor-plate tracks. Drivers will have available up to 10 horsepower more relative to the last time they raced at the 2.66-mile oval in the spring, after NASCAR decided to increase the size of the restrictor-plate opening by 1/64th of an inch up to 57/64ths. Additionally, the relief valve on the car's cooling system will be re-calibrated to reduce pressure by around eight pounds per square inch, which should prevent engines from running on the edge of the temperature gages for as long as before.
