APR Stage III Supercharger System

APR’s Engineering Teams have been hard at work on the  Audi 4.2l V8 FSI supercharger application. Producing 590hp and 510 ft-lbs of torque, APR’s RS4 Stage III propels one of Audi’s most prestigious performance vehicles to new levels of acceleration and performance.

Applying forced induction to a normally aspirated production engine is no simple task and APR’s Engineering Teams understand that new innovations, processes and components must be incorporated into the design to insure OEM reliability and drivability while producing incredible performance results. Within APR’s Stage III, you will find more components and higher quality parts at every comparison than with any of the competing products currently available. The goal of APR’s design was not merely fitment and operation but consideration of the long term effects of such a dramatic power increase and the overall reliability of the vehicle. Extra steps must be taken to insure Performance Without Compromise.

Not only will RS4’s equipped with APR’s Stage III produce blistering increases in wide open throttle acceleration, daily driving is greatly improved with increased torque and horsepower available in even the lowest rpm’s of the power band. Less downshifting for passing and greater rates of acceleration at all points result in a driving characteristic of pure enjoyment in all situations. Both Drag Racing and Road Racing demands are taken into consideration during the design and calibration process in order to provide a well rounded solution for all enthusiasts.

The Calibration Team has spent countless hours in a wide range of environmental conditions to develop an ecu calibration that utilizes APR’s Stage III hardware in a safe and powerful manner. Hot weather, cold weather and everything in between has been considered with multiple prototypes operating in extreme conditions for long periods of time prior to the Stage III release.

The patented EMCS solution allows Stage III owner’s to use their factory cruise control to select the best calibration for their current driving situation. Two different pump gas calibrations and a race gas calibration allow the end user to select different power levels for different uses and enjoyment at the end user’s determination.

APR  has also developed calibrations specific to the fuel qualities in all areas of the world. Prototyping, testing, development and production is a worldwide exercise with it’s partners all over the globe. Expect similar performance, reliability and drivability whether you live in or travel to North America, Europe, Asia or South America, Africa and Oceania. APR’s Calibration Team has developed specific calibrations for your climate.
