APS Stealth Intercooled Twin Turbo Pontiac G8 GT

There is no doubt that the release of the 2008 model Pontiac G8 GT will get the hearts of performance enthusiasts pounding for an engine enhancement system that would not only deliver a tidal wave of torque, but also unleash the true horsepower potential of the 6.0L V8 engine in the G8.

Right from the start, APS set out to deliver thoroughly engineered high horsepower intercooled tiwn turbo system for the new G8 - and with over 25 years of turbocharging and intercooling experience, APS has produced what is arguably the ultimate intercooled twin turbo system for this model Pontiac. Better still, APS has paid particular attention to ensure that the installation process is as easy and straight forward as possible.

A straight forward bolt on totally engineered system that utilizes the latest in water cooled turbocharger technology and with the industry's largest bar and plate intercooler, APS delivers a system that results in outrageous power and torque right across the entire RPM range.

With insane horsepower and monster torque, the APS Intercooled Twin Turbo High Output System performs like a strong 9L Big Block and raises the G8 GT performance enthusiast exclusively into the supercar club!

With APS production components of equal to or higher than factory quality and specification, the look and feel of the APS Intercooled Twin Turbo system is one that screams the professionalism that APS High Output Systems are renowned for.

Lift the hood and the engine bay looks neat and purposeful - a quantum leap over any turbocharger or supercharger systems available today - a signature of APS workmanship.

But great looks don't just stop there. At the business end under the engine bay is where all the action is.

High engine bay temperatures have always been the Achilles heel of forced induction engine performance. With each turbocharger tucked up under the chassis, heat is channelled away from the engine compartment for high engine durability and consistently high engine performance. With the APS stealth Twin Turbo configuration, under bonnet air temperatures are a fraction of traditional turbocharger designs. Let's face it, nobody likes to wait for extended cool down periods, when you can simply turn around and line up for another screaming pass down the quarter mile track.

High engine performance also demands a huge mass flow rate of cool air. With twin cold air intakes, one for each turbocharger, the APS Intercooled Twin Turbo system delivers the goods. With a total cold air capacity that far exceeds the demands of the base APS Twin Turbo system, there's plenty of air flow in reserve for those who wish to build larger capacity engines (400 ci plus engines).

If the turbocharger can be described as the heart of the system, then the intercooler must surely be the "lungs"!! APS has designed and manufactured a custom configured, vertical flow high efficiency intercooler utilizing custom designed light weight cast aluminium end tanks. Extremely high flow rates and massive charge air temperature reduction - a level of performance that other manufacturers can only aspire to achieve.

With a huge drag race specification bar and plate core, APS has achieved truly outstanding cooling and pressure results at such huge horsepower levels. So just like the APS turbochargers and twin cold air intakes, the APS intercooler system has massive additional headroom available for even higher power levels.

The true dual entry design of the APS intercooler system allows for the ultimate in true equal length balanced ducting from each turbocharger to the intercooler. This ensures the optimum utilisation of the intercooler core by spreading the charge air from each turbocharger evenly across the entire intercooler core - This is efficiency at its best!

With the prospect of many G8 performance enthusiasts building high cube/high power engines, APS has specified a pair of huge TIAL 38mm external wastegates for highly stable, high boost pressure applications on the APS Intercooled Twin Turbo System.

The APS specified TIAL external wastegates deliver a dedicated path for the diverted exhaust gas to bypass the turbocharger's turbine, hence creating the physical basis for a highly responsive and extremely stable boost management strategy that is designed to bypass massive amounts of exhaust gas from each turbocharger.

The end result? Insane horsepower and monster torque for your 6.0L V8 powered Pontiac G8. The APS Intercooled Twin Turbo High Output System performs like a strong 9L Big Block and raises the G8 performance enthusiast exclusively into the supercar club! Are you ready for the ride of your life?
