The speedometer system starts at the front left wheel of the DeLorean and ends at the instrument cluster.

Components[]

The system consists of the following components, in order from the front left wheel to the speedometer:

Wheel to Speedometer Cable to Speedometer Turn Ratios[]

The speedometer is calibrated such that when the speedometer cable turns at 1000 RPM, the speedometer reads 100 KPH (62 MPH)[1]. This comes out to approximately 1377 RPM of the speedometer cable at 85 MPH, which is the top end of the stock speedometer. The roughly 8:9 wheel to speedometer cable turn ratio (eight turns of the front left tire results in nine turns of the speedometer cable)[2] is maintained by gearing in the angle drive.

Troubleshooting[]

See the Speedometer Troubleshooting article for general information on diagnosing speedometer issues.
