1993 Supercharged V-8 Formula Firebird
|
Pontiac Special Vehicle Engineering built this Firebird Formula with a supercharged 4.3L L99 V-8 engine to test the performance potential of a smaller-displacement engine in a Firebird application. The steel-roofed Formula was an early '93 model, upgraded to WS6 specs. Though tough to see, the rear bumper fascia for the stock Formula has an empty spot where the passenger-side exhaust pipe would have gone. This car received a prototype version of the high-flow, single-outlet system that made it to production on the '98 WS6 Firebirds. View Related Article
