The front-end of the original chassis had to be re-engineered, as the twin-turbo 482 was a complex engine to package. A BOP belt-drive system puts the distributor up front, which provides clearance for the unique rear-entry throttle body and inlet plumbing. The 91mm Turbonetic ball-bearing turbos are huge-a significant packaging challenge. They bolt to custom headers, and the Turbonetics wastegates are adjustable and can dial in or out over 1,000 hp. Normal boost settings are 36-40 psi, though they can be changed to accommodate track conditions.
Both exhaust turbines feature massive 5-inch outlets, which are routed through the front fenders. The noise this engine makes sounds like machine gun fire.
The rear suspension is typical Pro Mod fare, with massive coilovers suspending the Strange custom-fabricated, 9-inch housing. Gearing is a fairly conservative 3.89:1, which helps with launch and trap speeds.

The massive power that the twin-turbo 482ci Pontiac makes is readily evident with the nearly uncontrollable burnouts it performed with Rodney Butler at the wheel.
