VDO SingleViu 100mm (4") Tachometer - 3000 RPM

The VDO SingleViu 100mm (4") Tachometer - 3000 RPM is an essential engine management instrument for street mechanics, performance builders, and enthusiasts who demand real-time RPM feedback without relying solely on engine control unit displays. This analog gauge delivers immediate visual confirmation of engine speed, critical for precise tuning work, shift timing optimization, and verifying carburetor or fuel injection response during startup and load transitions.

Whether you're diagnosing a freshly rebuilt small-block, validating ignition timing on a carbureted engine, or monitoring redline margins during spirited driving, a dedicated tachometer provides the tactile, split-second feedback that digital screens cannot match. VDO's SingleViu series combines robust mechanical movement with a maximum range of 8000 RPM, making it ideal for naturally aspirated engines and modest forced-induction applications where redline sits comfortably below 7000 RPM. The 100mm (4-inch) face provides clear, sweeping needle indication that remains legible in sunlight and low-light cabin conditions.

The compact design suits dash pods, steering column mounts, and custom gauge clusters without consuming excessive real estate. The gauge accepts negative trigger input from ignition systems, distributors, or electronic modules, enabling installation on carbureted, fuel-injected, and early turbocharged platforms with minimal wiring complexity. Precision VDO calibration ensures repeatability across various engine types, making this tachometer a reliable choice for any automotive enthusiast.
