2-1/16in C/S Boost/Vac Gauge 30in HG/20psi

The AutoMeter 2-1/16in C/S Boost/Vac Gauge is a dual-range analog instrument designed for engine performance monitoring in street and competition vehicles. This mechanical gauge displays both boost pressure and vacuum conditions on a single dial, making it essential for turbocharged, supercharged, and naturally aspirated engine tuning. Whether you're diagnosing intake manifold vacuum for carburetor tuning or monitoring turbo boost levels under load, this gauge provides real-time feedback that serious enthusiasts and mechanics rely on for accurate engine management.

This AutoMeter gauge features a cobalt-colored face with a 2-1/16-inch diameter dial that reads from 30 inches of mercury on the vacuum side to 20 psi on the boost side, covering the full operating spectrum of forced-induction and naturally aspirated engines. The mechanical, analog design eliminates electronic dependency and vibration sensitivity, delivering reliable measurements in harsh underhood environments. A black face background ensures excellent contrast and readability in daylight or shop conditions, while the compact 4.75 x 4.45 x 5.1-inch footprint allows flexible mounting in tight engine bays or dash installations.

Professional engine builders, performance tuners, and DIY enthusiasts benefit most from this gauge when diagnosing fuel system issues, verifying turbo function, or validating carburetor calibration. Installation requires a vacuum or boost line connection to an appropriate intake manifold or turbo source, making it universally compatible with carburetor-fed and fuel-injected platforms. At 0.6 lbs and weighing virtually nothing on the engine bay, the 2-1/16in C/S Boost/Vac Gauge integrates seamlessly into existing dashboard layouts, custom gauge clusters, or portable diagnostic setups for field testing and real-time performance validation.
