Garrett Powermax Golf R Audi S3



2014 – 2018 Volkswagen / Audi 2.0L TSI MK7 Stage 2 Turbocharger


Garrett PowerMax™ turbocharger upgrades for the Volkswagen and Audi MK7 2.0L TSI engine platform is engineered to increase engine performance while maintaining OEM installation specifications. Stage 1 (485 HP*) and Stage 2 (600 HP*) upgrades maximize efficiency and airflow compared to the OEM turbocharger. High temperature, Mar-M alloy turbine wheel and twin-scroll stainless steel turbine housings are rated for up to 1050° C. These turbochargers are fully assembled with a calibrated electronic actuator and ancillary components for direct OEM fitment.

WARNING: Maximum allowable turbocharger speed is 165krpm (Stage 2). The use of this product above max turbocharger speed is at the owner’s risk and can result in damage and premature failure. To protect the turbocharger from over-speed when operating, a speed sensor port is machined into the compressor housing for the fitment of speed sensor part numbers 781328-0003 (includes sensor and gauge), and 781328-0004 (includes speed sensor). Speed sensors are sold separately.

*Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The target power has been calculated based strictly on the choke flow of the compressor map (total turbo capability), which represents the potential flywheel power.
