Description
The Garrett Stage 1 GT1749S PowerMax Turbocharger Kit is designed for the 2011–2012 Ford 3.5L EcoBoost, providing a direct-fit performance upgrade designed to increase airflow and engine performance while maintaining OEM-style installation.
Garrett developed the PowerMax turbocharger upgrade for enthusiasts seeking increased performance without moving to a highly modified turbo system. The Stage 1 design uses an optimized compressor aerodynamic package to increase airflow compared with the factory turbochargers.
Garrett states that the PowerMax Stage 1 upgrade provides 22% more flow than the OEM turbocharger and is capable of supporting up to 300 HP per turbo, based on compressor-map choke-flow calculations. Actual vehicle performance depends heavily on engine modifications, calibration, tuning, and operating conditions.
The turbocharger kit is designed as a direct drop-in replacement, with the turbocharger system fully assembled and calibrated for compatibility with the OE installation configuration.

PowerMax Performance
The Garrett PowerMax Stage 1 turbocharger upgrade is engineered to provide greater airflow capacity than the original turbochargers while retaining the factory-style installation configuration.
Garrett's published testing and engineering data indicate that the PowerMax turbo provides 22% more flow than the OEM turbocharger and can support up to 300 HP per turbo. These figures represent turbocharger capability rather than guaranteed vehicle output, and Garrett notes that actual performance depends on vehicle modifications and professional engine calibration.
The optimized compressor aerodynamic design and lightweight forged fully-machined compressor wheel are key elements of the PowerMax system's increased flow capability.
Installation & Tuning
The Garrett PowerMax system is designed as a direct-fit, drop-in upgrade using the OEM installation configuration. The turbocharger kit is supplied fully assembled and calibrated, with the design intended to be interchangeable with the original-equipment hardware.
Professional engine calibration and tuning are recommended after installation to take full advantage of the increased airflow capability and ensure the turbochargers operate correctly with the vehicle's overall setup.
Garrett specifically notes that the boost response of the PowerMax turbocharger compared with the OEM turbocharger has not been tested, so no specific improvement in spool or boost response should be assumed.
Important Performance Notice
The advertised 300 HP per turbo figure represents the calculated potential of the turbocharger based on compressor-map choke flow and does not guarantee a specific engine power output. Actual results depend on tuning, supporting modifications, fuel system capability, engine condition, and other vehicle-specific factors.
