John works with Chris Krug, a South Carolina drag racer who put a helicopter engine in his minivan. After they drag race down Main Street, John and Chris try to build the ultimate jet-powered garden tool. The design isn't pretty, but it sure makes a hell of a lot of smoke. And where there's smoke… there's fire in the driveway. And when they test their new contraption in front of Chris' friends, more sparks are gonna fly.
