DAYTONA BEACH, Fla. (AP) - NASCAR is making another change to cars for the Daytona 500, this one because temperatures are expected to reach 80 degrees during the season-opening race.
Sprint Cup officials say teams can add an extra inch to grill openings, allowing more air to flow to engine-cooling radiators.
The change was made following the final practice session Saturday and should help drivers keep their engines cooler at speeds nearing 200 mph around Daytona International Speedway on Sunday.
NASCAR made three changes earlier in the week, reducing the size of the horsepower-sapping restrictor plates, adding a pressure-relief valve to cooling systems and reducing the size of grill openings. The moves were made to slow downs cars after speeds topped 206 mph.
