NASCAR has impounded the top six cars following Sunday’s event for testing on the chassis dyno. The Fords driven by Jeff Burton, Dale Jarrett and Jeremy Mayfield, the Chevrolets of Jeff Gordon and Dale Earnhardt, and the Pontiac piloted by Ernie Irvan were all put through their paces. The purpose of the test is to determine the horsepower output of the engine as measured at the rear wheels.(GoRacing)(9-7-98)
