The Garrett turbo RPM Speed Sensor Kit with display has been developed to accurately measure and display the rotational speed of the compressor wheel in Garrett G-Series turbochargers. This allows you to determine exactly where your turbo is positioned within the compressor efficiency map. Combined with boost pressure, you can immediately see whether the turbo is operating efficiently, is underutilised, or is in a dangerous zone such as overspeed or surge. This makes the kit an essential tool for tuners and serious enthusiasts alike.
The kit can also be used in conjunction with a data logger for in-depth analysis (see manual/PDF).

Frequently Asked Questions
Why is a turbo RPM gauge important?
Because boost pressure alone does not indicate whether a turbo is operating efficiently or running too fast. RPM monitoring prevents overspeed and damage.
Is this only for professional tuners?
No, it’s also ideal for hobbyists who want to tune their setup correctly and safely.
Can I combine this kit with data logging?
Yes, the sensor is compatible with data loggers. Please refer to the manual for connection instructions.
