The Porsche 911 Turbo S is quick through the quarter-mile. It launches like its moving mountains, and few cars can keep up with it. But a new video demonstrates that no throne is safe in the automotive world thanks to the aftermarket scene. It pits a tuned BMW M3 Competition against the Turbo S in a series of drag races to see if some affordable upgrades can make a performance difference.
The Porsche is stock, featuring the brand’s twin-turbocharged 3.8-liter flat-six engine. It produces 650 horsepower and 590 pound-feet (800 Newton-meters) of torque, which routes to all four wheels through the eight-speed gearbox. It weighs 3,615 pounds (1,640 kilograms).
