Get the most out of your Turbocharger!

The Garrett Turbocharger Speed Sensor Kit offers the ability to monitor the inner workings of your turbocharger to ensure longer life and maximum performance at an affordable price! By constantly monitoring your turbocharger's shaft speed through either a data logger or the Garrett-branded speed sensor gauge, you acquire a more complete picture of your turbocharger's performance.

Maximum Performance
Comparing boost levels and shaft speed on a compressor map, you can determine the ideal operating conditions to ensure peak power over a wider operating range. All Garrett Turbocharger Speed Sensor Kits are compatible with dataloggers to enhance engine tuning capability. In addition, the Garrett-branded gauge's maximum speed recall function will retain the highest wheel speed for five minutes for easy mapping.

The data gained from the Garrett Turbocharger Speed Sensor Kit can be used to closely estimate the engine's flow behaviour without a flow bench. Flow information is invaluable for determining if the turbocharger is reaching its maximum performance, for validating the turbo match, and for ensuring that it is not overspeeding, allowing you to avoid potentially damaging operating conditions. This kit could even be used in conjunction with an aftermarket ECU to limit compressor speed.

Easy to Use
The Garrett Turbocharger Speed Sensor works with any turbocharger to accurately determine compressor wheel speed. The instructions include detailed drawings of the exact machining specifications for all Garrett turbochargers, as well as general guidelines for other compressor housing types. The Garrett Turbocharger Speed Sensor Kit includes all necessary wiring for easy installation and simple data logging.

Included in this kit:
  • Speed Sensor
  • Wiring Harness
  • Installation Instructions
  • Garrett Speed Sensor Gauge
