Racepak Clutch RPM Cables

Racepak clutch RPM cables are connecting wires used in motorsports data acquisition systems. They link the vehicle's transmission input shaft (clutch) speed sensors to the main data logger (such as the Racepak V300SD or V500SD).

How They Work and Why They Matter:

* Clutch Slip Calculation: By comparing the engine RPM to the clutch/input shaft RPM, tuners can calculate precise clutch slip
* Diagnostics: This data allows racers to identify inconsistent engagement, hydraulic lag, or heat-related slip degradation that affects power delivery and drivetrain longevity
* System Integration: These cables are typically part of a larger Racepak RPM harness that also routes engine and driveshaft RPM data

Typical Specifications:

* Cable: Standard 240 in. unterminated yellow wire
* Sensors: They rely on "zero-crossing" RPM sensors and magnets typically installed in the transmission housing or clutch can
