Twin Turbo G8 GT is possible

MELBOURNE, Australia — The Australian performance company APS Engineering has set the hearts of performance enthusiasts pounding with the release of an engine enhancement system for the Pontiac G8 GT that not only delivers a tidal wave of torque, but also unleashes a massive 557 horsepower from the car's 6.0-liter V8 engine, according to the company.

With more than 25 years of turbocharging and intercooling experience, APS has produced what is arguably the ultimate intercooled twin-turbo system for this model Pontiac. It's a bolt-on, totally engineered system that uses the latest water-turbocharger technology and the industry's largest bar and plate intercooler.

Claiming nearly 200 more hp than the standard Pontiac G8 GT and monster torque of 583 pound-feet, the APS intercooled twin-turbo high-output system is the definition of power. As the company puts it, a driver would be forgiven for mistaking this system for "a strong 9.0-liter big-block."

The turbochargers are tucked up under the chassis. This channels heat away from the engine compartment to improve engine durability and ensure consistent performance.

APS Engineering has developed the system on a Holden Commodore SS, the Australian model on which the Pontiac G8 GT is based. More details and specifications are available at the APS Engineering Web site.
