Supercharged Ford 7.3-Liter Godzilla V8 Cracks 1,000 HP On Dyno

More power equals more boost

The Ford 7.3-liter V8 engine is already very popular with tuners despite it being only a few years old. Harrop, Australia is exploring the engine’s potential by creating a supercharger. They expect the powerplant to reach four-figure horsepower.

The V8 is using the throttle from a Ford Mustang Shelby GT350, and running on gasoline at the beginning. The engine produces 550 horsepower (410kilowatts) without the natural aspiration and then gets an instant boost to 803 horsepower (599 kW), when the supercharger is added. These are impressive gains considering the stock rating of 430 horsepower (321kW) . There’s more to come.

The V8 then switches to E85 fuel, increasing the boost. The V8 produces 944 horsepower (704 kW) at 18 psi and 972 pound-feet (1 318 Newton-meters). Keep in mind that the engine still runs on the stock camshaft.

The team then replaces the GT350’s 87-millimeter throttle body with a 102 millimeter piece. The boost is also increased to 19 psi. The result is 980 HP (731 kW), and 980 Lb-ft (1 1,329 Nm).

The final run sees the increase to 20 PSI. The V8 is now capable of producing 1,015 horsepower (757 kW) or 988 lbft (1,339Nm). If the engine and supercharger are capable of handling it, then a few extra pounds could be enough to increase the torque to a four-figure figure.

The team plans to put the 1,000+ horsepower big-block V8 into a Ford Falcon drag racing car. According to estimates, the car could travel the distance in 8.9 seconds and reach speeds of 150 mph. This would be quite an accomplishment on the strip.
