Audi B8 S5 4.2L FSI V8 Stage III Supercharger System

APR presents the Audi B8 S5 4.2l Stage III supercharger system.

APR’s Engineering Teams are pleased to present our second iteration of the Audi 4.2l V8 FSI Supercharger application. Producing over 537 HP and 443 ft-lbs of torque, APR’s B8 S5 Stage III adds over 187 horsepower which completely transforms Audi’s latest coupe 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 S5’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.

APR’s 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.

APR’s 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’s Calibration Team 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 APR partners all over the globe. Expect similar performance, reliability and drivability whether you reside 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.

APR began supercharger development of the Audi 4.2L V8 engine in 2004. After several design reconsiderations and the availability of new technologies, APR is confident that the each component included in the Stage III system is of the highest quality and is perfectly matched to the 4.2L application. All components necessary for a full installation and enjoyment of use including the expertly recalibrated engine management software are included with the exception of an upgraded clutch for the transmission. APR's Engineering Team developed and selected the best components possible, not a component that merely fits the bill but exceeds expectations in order to produce unsurpassed quality.

APR's HTV1320 Supercharger, Intake Manifold, Supercharger Inlet Feed and Intercooler Cores are pre-assembled and pressure tested prior to final delivery to the end user. Control over such a delicate assembly process reduces installation labor rates and certifies the operation of the primary components in the Stage III supercharger system. Eliminating guesswork and facilitating installation are further testaments to APR's achievement of an all inclusive and exclusive offering for the Audi S5.

APR's Cast Aluminum Supercharger Inlet Feed offers precise positioning of the OEM throttle body to allow for the OEM airbox or most aftermarket intake systems to be maintained. Air flow from the intake tract through the throttle body is handled in the most efficient manner possible to match the accomplishments of the APR Cast Aluminum Supercharger Intake Manifold design. Smooth transitions, reliable design and proper metering of the incoming air are provided by the APR Stage 3 Supercharger System thanks in part to such cutting edge and all encompassing design characteristics of the Cast Aluminum Supercharger Inlet Feed.

APR's Cast Aluminum Supercharger Intake Manifold is designed with the greatest attention to detail using advanced design techniques to create maximum performance opportunity. Relocation of certain engine management sensors into the new Intake Manifold is necessary to maintain all OEM safety and drivability features as included in the OEM ecu calibration. Port matched and velocity tuned runners deliver the compressed air to the combustion chamber in a manner that promotes maximum power delivery and fuel efficiency. OEM quality idle, cold start and transitional throttle application is maintained due to incorporation of such advanced design characteristics by APR's Engineering Teams.
