THE PES G4 - DESIGNED FOR THE MPI (MULTI PORT INJECTED) AUDI/VW 4.2L 5V V8 AND THE AUDI R8 4.2 FSI


Introducing the NEW PES G4 MPI supercharger system for the VAG 4.2L 5V engine group as well as the Audi R8 4.2FSI . At the heart of the system is the PES cast aluminum intake manifold and an Eaton M90 supercharger. This roots-type positive displacement supercharger delivers instant, seamless boost throughout the RPM range. Eaton superchargers are used as OEM equipment on Mercedes Benz, Aston Martin, and Jaguar automobiles. The system is supplied complete with all parts necessary for installation.

The addition of forced induction necessitates enhanced fuel delivery to ensure the correct air/fuel ratio for performance and safety. The kit includes PES’s in house ECU recalibrating and offers ultra smooth drivability, and seamless power delivery. The G4 MPI system is the result of over 2 years of design and road testing using data logging software. PES's vehicles are tested under a wide variety of driving conditions ranging from "easy" daily commutes to severe track conditions. PES also tests their systems in a broad range of temperatures, from bitter winter cold to blazing summer heat. Testing is also conducted using both Dynojet and Mustang dynamometers. PES is so confident in the reliability of the system that they offer a one year, unlimited mileage warranty.
