2-1/16in P/S Boost Gauge 0-100psi

The AutoMeter 2-1/16in P/S Boost Gauge 0-100psi is a mechanical analog instrument designed for automotive enthusiasts and professional tuners who need reliable real-time boost pressure monitoring. This gauge measures positive pressure (P/S) in the intake manifold, allowing drivers and technicians to verify turbocharger or supercharger performance and diagnose fuel system and engine efficiency issues. Whether you're tuning a forced-induction engine, verifying wastegate function, or monitoring daily-driver reliability, this boost gauge delivers the accuracy needed for informed decisions.

Built by AutoMeter—a leader in precision gauges—this 2-1/16 inch diameter boost gauge features a white face with clear, easy-to-read markings across a 0–100 psi range. The mechanical design operates without electronic components, eliminating dependency on power sources and ensuring consistent readings in high-vibration engine bays. Pressurized boost lines connect directly to the gauge via a standard fitting, transmitting real-time manifold pressure to the needle mechanism. This analog display provides immediate feedback, critical for monitoring transient boost spikes and steady-state pressure hold, making it essential for forced-induction diagnostics and performance verification.

This boost gauge suits turbocharged and supercharged vehicles across domestic and import platforms, from street applications to competition engines. Installation typically requires a small-diameter boost line tapped from the intake manifold or intercooler outlet, routed through the firewall to the dash or pillar pod. The compact 4.8-inch footprint fits standard 2-1/16 inch gauge clusters and aftermarket mounting solutions. Weighing just 0.65 pounds, it integrates easily into custom gauge panels without adding bulk. Technicians and power-addict owners alike rely on AutoMeter boost gauges for dependable pressure confirmation during tuning sessions, dyno testing, and street validation.
