TURBINE HOUSING
PRODUCT DETAILS
The G-XRace GXR55-94 94.9mm is from Garrett's G-XRace line, developed for drag racing. G-XRace compressors use Garrett's XBoost technology for more airflow and higher pressure ratio capability than the comparable Garrett G-Series or GTX model, and several sizes are built around drag racing class compressor inducer rules. Confirm your class rules before ordering.
Garrett rates the G-XRace GXR55-94 94.9mm for 1,400 to 2,700 horsepower on 3.0 to 12.0 liter engines.

Important Information
Garrett calculates its horsepower ratings from the compressor map choke flow, which represents the potential flywheel horsepower of the turbo. Actual results depend on the engine, supporting modifications and calibration.
Garrett sets the maximum allowable speed for this turbo at 75,000 rpm. Operating above that speed can damage the turbo and cause premature failure. A turbo speed sensor (sold separately) lets you monitor shaft speed.
For race vehicles only. Not for use on public roads.
Installation and Tuning Available at Race Protocol
Turbo system design, installation and dyno tuning are available in house. Call (724) 732-8948 to discuss your build.
