2-1/16 in Boost Gauge

The AutoMeter 2-1/16 in Boost Gauge is a mechanical analog instrument designed for drivers who need reliable, real-time monitoring of engine boost and vacuum levels. Whether you're tuning a turbocharged or supercharged engine, diagnosing intake vacuum issues, or simply tracking performance metrics, this gauge delivers accurate readings across a -30 in HG to +20 psi range. Built to withstand the demands of automotive enthusiasts, professional mechanics, and performance builders, this compact gauge integrates seamlessly into factory or custom dash configurations.

This mechanical gauge operates without electronic sensors or power dependencies, ensuring consistent performance under extreme engine conditions where digital systems may falter. The 2-1/16 inch diameter face features a black background with clear, easy-to-read markings that remain visible in variable lighting. The dual-range design—spanning from 30 inches of vacuum on the negative side to 20 psi of boost on the positive side—enables users to diagnose both supercharger performance and fuel system or intake air leaks with a single instrument. Sturdy analog movement and industry-standard mechanical linkage provide years of reliable service without calibration drift or electronic failure.

Technicians and engine builders favor this AutoMeter boost gauge for turbocharged and supercharged applications where boost control and engine health monitoring are critical. The compact 2-1/16 inch size fits standard aftermarket gauge pods, custom enclosures, or factory dash openings, making installation flexible for both street and race vehicles. Vacuum readings help identify intake manifold leaks, faulty PCV systems, or restricted air filters—diagnostic capabilities that extend engine life and optimize fuel economy. This gauge pairs well with supporting instrumentation like fuel pressure, oil temperature, and air/fuel ratio monitors for comprehensive engine diagnostics.
