Garrett G-Series Turbo Speed Sensor Pro Kit (No Gauge) | 781328-0004

The Garrett G-Series Speed Sensor Pro Kit measures turbocharger shaft speed, a key factor in determining ideal operating conditions. Comparing shaft speed and boost levels on a compressor map helps confirm the turbo match, find peak power over a wider operating range, and avoid overspeeding.

Kit Includes: G-Series speed sensor, main wiring harness, power / logger pigtail, fixing screw, and drawings and instructions. Gauge not included.

Features:

• Plug-in installation with no length adjustment needed: remove the plug, insert the speed sensor and tighten the bolt
• O-ring between the compressor housing and backplate reduces the possibility of boost pressure leakage
• Compatible with dataloggers to enhance engine tuning capability, and can be used with an aftermarket ECU to limit compressor speed
• Speed data can help estimate engine flow behavior without a flow bench, and confirm the turbo is not reaching a damaging overspeed condition

Fitment: Garrett G-Series turbochargers with a fully machined speed sensor port, including G25-550, G25-660, G30-660, G30-770, G35-900, G35-1050, G40-900, G40-1150, G42-1200 and G42-1450. Not compatible with GT / GTX speed sensors due to the new design and sizing.
