Racepak Driveshaft RPM Cables

Racepak driveshaft RPM cables are specialized wiring components designed to connect a car's driveshaft speed sensor to a data logging system (such as the Racepak V300SD or V500SD). They transmit rotational speed data, allowing racers to analyze vehicle launch characteristics and engine performance. These cables act as the physical link between the sensor mounted at the driveshaft and the primary power/RPM harness.

Key details:

* Function: The cables relay a pulse signal from the driveshaft sensor (which reads magnets or a trigger wheel on the driveshaft) back to the data logger. This information is crucial for calculating driveshaft speed, slip, and optimizing 60-foot launch times in drag racing
* Compatibility: Depending on the racing setup (i.e., dragsters, door cars, or motorcycles), the cables connect to specific main harnesses and range in length to accommodate different vehicle layouts
* Replacements: Because of the harsh environment in race cars, the modular design allows racers to replace just a single failed RPM cable rather than the entire wiring harness
