Garrett GXR50-76 Turbocharger – Ball Bearing Performance with Broad Powerband 7+7 Compressor Technology

Utilizing the same proven compressor wheel as the GXR47 paired with the higher-flowing Garrett G-Series G50 turbine, the Garrett G-XRace GXR50-76 Turbocharger is the ideal solution for racers looking to improve turbine flow, reduce over spooling, or make more efficient power at lower boost levels.

Designed for serious horsepower enthusiasts and competitive motorsport applications, the GXR50-76 delivers exceptional airflow, rapid response, and relentless top-end performance. Garrett’s advanced dual ball bearing center section combined with the highly efficient 7+7 compressor wheel design creates an extremely broad and usable powerband — making this turbo an excellent choice for drag racing, roll racing, dyno competition, and high-performance street builds.

The dual ball bearing system minimizes rotational friction for faster spool-up, improved transient response, and increased durability under extreme boost conditions. Meanwhile, the advanced 7+7 compressor wheel enhances compressor efficiency and airflow stability across the RPM range, delivering smoother acceleration and sustained horsepower throughout the pull.

Compared to the GXR47, the GXR50-76 utilizes the larger flowing G50 turbine section, making it an excellent option for applications where additional turbine flow is desired without sacrificing the broad powerband characteristics the GXR series is known for.

FAQs

What makes the GXR50-76 different from the GXR47?

The GXR50-76 uses the same compressor wheel as the GXR47 but incorporates a larger flowing G50 turbine section for improved turbine efficiency and reduced over spooling.

What are the benefits of the 7+7 compressor wheel design?

The 7+7 blade configuration improves airflow efficiency, turbo response, and helps create a broader, more usable powerband.

Is the GXR50-76 a ball bearing turbocharger?

Yes. The GXR series utilizes Garrett’s dual ball bearing center section for faster spool-up, improved throttle response, and enhanced durability.

What applications is this turbo best suited for?

The GXR50-76 is ideal for drag racing, roll racing, high-horsepower street builds, and high horsepower commercial diesel applications. 

Does the larger turbine help reduce lag?

The larger turbine improves overall turbine flow and efficiency, but the larger size will make it spool slower then a GXR47.
