This speed sensor is suitable for use with Garrett GT and GTX series turbochargers but can also be adapted to use with with other compressor housings. Some GTX turbos have a speed sensor port as standard so fitting is simple. Other turbo housings will need to be machined for fitment, detailed instruction of how to do this are included.Direct fit for some Garrett GTX series turbochargersCan be fitted to other types of turboMeasures compressor wheel speed for data logging or mappingCan provide information invaluable to determine if the turbo is the correct specification for the engineThe Garrett speed sensor can be a valuable tool as it allows a comparison between boost levels and shaft speed on a compressor map. This information can determine the ideal operating conditions for the turbo and insure peak power over a wider rev range. The speed sensors are compatible with data loggers to provide data for optimum tuning and ensuring the turbo is not exceeding the maximum safe RPM. They are
