Sport Truck
This ’92 GMC Typhoon has been lowered 2 inches in the rear and 3/4-inch in front to further the ground effects of the body styling. A bigger rear antisway bar and rear wing add stability, and the stock wheels have been custom machined and polished. Performance alterations include a custom 3-inch-diameter cat-back system, a custom-made Ram Air duct, and a host of Kenne-Bell products such as a performance PROM chip, injectors, fuel-boost pump, cool-air intake system, underdrive pulleys, and electronic fuel-management system. This Typhoon recently won First Place in a local SCCA autocross and took fast time of the day, beating some Corvettes by a full 2 seconds over a 40-second course. And this hot truck is proudly owned by Jim Longwith, of Rock Hill, South Carolina.
