Now, the perfect partnership has been formed to take the C5 to a performance level that has thoroughbred supercars running scared. Drawing on 30 years of turbocharging, supercharging, intercooling and engine management system design and production knowledge, APS has created the ultimate High Output System for the Corvette's LS1 engine.

Drawing on the man-years of APS engineering and testing efforts for the leading APS C6 and GTO Intercooled Twin Turbo Systems, APS raised the bar further still with the C5 APS Twin Intercooled Twin Turbo System.

A straight forward bolt on totally engineered system that utilizes the latest in liquid cooled turbocharger technology and with a pair of huge bar and plate intercoolers, APS delivers a system that results in outrageous power and torque right across the entire RPM range.

Huge external wastegates deliver enhanced boost pressure stability under extremely high boost pressure conditions in addition to a great degree of boost pressure flexibility. For example, with a simple change of the wastegate spring specification, a variety of boost pressures can be set - from 5 psi all the way through to over 20 psi.

With insane horsepower and monster torque, the APS Intercooled Twin Turbo High Output System performs like a strong 9L Big Block and raises the C5 performance enthusiast exclusively into the supercar club!

Best of all, the APS enhanced Corvette delivers uncompromised driveability. Crisp throttle response, tidal waves of torque, silky smooth highway cruising and excellent fuel economy all add up to an outstanding daily driver - and at your whim, mash the pedal and unleash the beast within.

Another stand-out feature of the APS intercooler system is that the stock air conditioning system is retained and unencombered. By specifying two large bar and plate intercoolers at each corner of the front of the car, generous air-flow is maintained into and through the stock air conditioning and engine cooling radiators - in addition to a high volume of fresh air flow through each intercooler (requires the installation of Z06 fog lamp opening mesh inserts). This ensures the best possible air flow through the engine radiator, air conditioning condensor and intercoolers - hence the best possible cooling from the stock radiator components.

High volume / high precision tooling ensures that the highest quality components possible are created for the APS intercooled Twin Turbo System. Precise NC machined jigs and fixtures are used to locate components with high accuracy in 3-dimensions during construction. The result is a straight forward bolt-on totally engineered system that fits first time - every time. 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 - right down to provision for the stock MAF meter via unique reinforced silicon hoses.

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.

Power at the Wheels and Turbocharger Boost Pressure. Stock mufflers, 93 (R+M)/2 octane fuel (East Coast fuel blend).
