5in S/C 9000 RPM Playback Tach

The 5in S/C 9000 RPM Playback Tach by Autometer is engineered for serious enthusiasts and mechanics who demand precision engine monitoring during high-performance driving and custom vehicle builds. Whether you're tuning a naturally aspirated engine, managing a supercharged or turbocharged setup, or simply need reliable RPM data in the cockpit, this gauge delivers real-time feedback that allows you to optimize shift points, monitor fuel mapping, and protect your engine from over-rev conditions. The 5-inch diameter makes it a commanding presence on any dashboard while maintaining legibility at a glance during spirited driving.

This tachometer features a maximum range of 9000 RPM, making it ideal for both street and track applications where sustained high-RPM operation is common. The "Playback" functionality allows you to review engine performance data after a run, helping you identify shift timing opportunities and engine behavior patterns without taking your eyes off the road during operation. Autometer's analog movement design provides immediate visual feedback that digital readouts often cannot match, while the precision internal mechanics ensure accuracy across the entire range. The gauge housing is constructed to withstand vibration and thermal stress typical in engine bays, and the dial markings are optimized for quick reference during critical moments.

Performance mechanics and weekend warriors benefit most from this gauge when upgrading vehicles with modified powerplants that operate above factory RPM limits. Installation requires standard gauge wiring to the ignition system and a secure 5-inch gauge mount in your dashboard or custom panel—compatibility with most universal automotive harnesses makes integration straightforward for both professional shops and DIY builders. Whether mounted alongside a full Autometer suite or as a standalone upgrade, the 5in S/C 9000 RPM Playback Tach serves as a critical monitoring tool for engine longevity and performance optimization during development and daily driving.
