Watch this 2013 Ford Shelby GT500 pull a 9-second quarter mile

The 2013 Ford Shelby Mustang GT500 is an impressive piece of hardware right out of the box. It's a package capable of pulling 11-second quarter mile passes one minute and lapping your favorite road course with genuine fury the next thanks to its impressive suspension tuning and heady 662-horsepower. But how much quicker can its supercharged V8 get with a little tweaking? The guys from Lethal Performance recently set out to find the answer. The team isn't saying exactly what they've done to the king Pony, though we can see a set of dragstrip-friendly "bigs n' littles" have found their way into the wheel wells.

As a result, the 3,852-pound two-door bolted down the drag strip in just 9.77 seconds. Judging by the "thank you" list in the video's credits, this GT500 may even be rocking a shot of nitrous, though we can't say for certain. Check out the full clip for yourself below.
