Garrett GXR50-80 Turbocharger – High Flow Ball Bearing Turbo with 80.9MM Compressor Inducer & Broad Powerband Performance

The Garrett G-XRace GXR50-80 Turbocharger takes the proven performance characteristics of the GXR lineup to the next level by incorporating a larger 80.9MM compressor inducer for increased airflow and horsepower capability while maintaining the exceptional response and broad powerband the GXR series is known for.

Designed for serious racers and high-horsepower enthusiasts, the GXR50-80 combines Garrett’s advanced dual ball bearing center section with the highly efficient 7+7 compressor wheel design to deliver rapid spool-up, outstanding transient response, and relentless top-end performance. The larger compressor inducer allows the turbo to move significantly more air, making it an ideal choice for high-boost applications demanding increased flow and elevated horsepower potential.

Built around the larger flowing G50 turbine platform, the GXR50-80 is engineered for applications where turbine efficiency, top-end power, and airflow capacity are critical. Whether you're drag racing, roll racing, competing on the dyno, or building an all-out street car, this turbocharger delivers the performance needed to support extreme power goals without sacrificing drivability.

The advanced 7+7 compressor wheel configuration enhances compressor efficiency and helps create a much broader and more usable RPM range. Combined with Garrett’s ball bearing technology, the result is a turbocharger capable of producing smooth, responsive power delivery with excellent spool characteristics and sustained airflow at high RPM.

FAQs

What makes the GXR50-80 different from the GXR50-76?

The GXR50-80 utilizes a larger 80.9MM compressor inducer, allowing for increased airflow and greater horsepower potential compared to the GXR50-76.

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

The 7+7 wheel design improves compressor efficiency, airflow stability, and turbo response while helping create a broader and more usable powerband.

Is the GXR50-80 a ball bearing turbocharger?

Yes. Garrett’s dual ball bearing center section improves spool-up, throttle response, and durability under extreme racing conditions.

What applications is this turbo best suited for?

The GXR50-80 is ideal for drag racing, roll racing, dyno competition, and high-horsepower street or motorsport builds.

Does the larger compressor affect spool characteristics?

While the larger compressor increases airflow and horsepower capability, Garrett’s ball bearing system and efficient compressor design help maintain excellent response and drivability, but the spool will be slightly slower then the 76MM version.
