Description
The Garrett G-XRace GXR47-76 76/109mm Ultra Street Super Core Turbocharger is built for extreme racing performance and high-horsepower drag applications. Designed with advanced XBoost technology, this universal performance turbocharger delivers exceptional airflow efficiency, allowing engines to produce massive power while maintaining reliability under high boost conditions.
Rated for up to 1700 horsepower, the GXR47-76 turbocharger is engineered for competitive motorsports, especially Ultra Street drag racing class builds requiring a 76.6mm compressor inducer. Its high-flow aerodynamic design improves efficiency at elevated flow rates, producing cooler and denser intake air to maximize combustion efficiency and overall engine output.
A lightweight aluminum backplate reduces turbocharger weight while maintaining strength and durability, helping improve spool characteristics and performance response. The integrated flange-style speed sensor port allows easy installation of a turbo speed sensor for accurate shaft speed monitoring, helping protect the turbocharger from overspeed and ensuring optimal performance and longevity.
This turbocharger features a patented design and is comparable in size to competitor frame size 7688, making it suitable for serious racing builds that require extreme airflow capability and high boost pressure.
