Paul's '07 Shelby GT500 is a mid-10-second Swiss clock on pump gas. However, add a 100-shot of Zex nitrous oxide and 118-octane Rockett brand race fuel, and the Drag Week 'Stang quickly becomes a 9-second street/strip player (16 psi of boost from the blower). The 9-second run (9.983 at 137.06 mph) was nailed down on Drag Week's final day, when the tour returned to its starting point at Beech Bend Raceway. Ambient temperature was more than 100 late-September degrees with 36 percent humidity, and density altitude was nearly 3,700 feet. When you take all of the variables into account-especially the mileage, all-out passes, the weight of the car in race trim (4,100 pounds) and the trailer (almost 6,000 pounds)-the Drag Week Shelby GT500 definitely is a badass street/strip ride.
