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 84,000 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
