1999 Pontiac Trans Am

The Project
Pushing a late-model F-Body platform to 744 rear-wheel horsepower and 823 wheel torque requires moving past factory limitations into extreme mechanical resilience. This 1999 Pontiac Trans Am relies on a blueprinted, hand-built 408 cubic inch iron-block engine packed with heavy-duty Callies and Wiseco forged internals. To push the chassis into supercar-slaying territory, we integrated a sophisticated Nitrous Outlet 102mm dual-stage plate system, completely isolated by its own dedicated fuel cell. Supported by an indestructible Strange Engineering Dana 60 rear end and a specialized drag suspension, this Trans Am converts massive nitrous torque into pure, forward trajectory.
