2-1/16in C2/S Boost/Vac Gauge 30in Hg/20psi

The 2-1/16in C2/S Boost/Vac Gauge 30in Hg/20psi from AutoMeter is a dual-range analog instrument designed for serious engine builders, tuners, and mechanics who demand real-time visibility into boost and vacuum conditions. This gauge is essential for monitoring turbo boost on modified engines, diagnosing intake vacuum on carbureted platforms, or fine-tuning fuel mixtures during dyno sessions.

Featuring a white face and a 2-1/16-inch diameter housing, this mechanical gauge provides reliable feedback with zero-lag response to transient boost spikes or vacuum fluctuations. Its mechanical operation eliminates electronic dependency, ensuring durability under the vibration and temperature extremes common in high-performance environments. The gauge accurately reads from 0 to 30 inches of mercury (Hg) on the vacuum side and from 0 to 20 psi on the boost side.

Ideal for turbocharged, supercharged, and carbureted engine platforms, as well as fuel-injected builds running vacuum-operated accessories, this gauge is a must-have for anyone looking to enhance engine performance. Installation requires a single vacuum line routed from the intake manifold or boost source, making it straightforward for mechanics and enthusiasts alike.
