2-1/16in P/S II Boost Gauge 0-35psi

The AutoMeter 2-1/16in Phantom II Boost Gauge (0-35psi) is an essential instrument for any serious turbocharged or supercharged vehicle builder looking to monitor real-time induction pressure safely and accurately. This gauge is purpose-built for forced-induction enthusiasts who need reliable pressure readings to prevent engine damage from overboosting and to verify boost controller function under load.

The gauge features a mechanical sender that connects directly to your intake manifold or custom boost port, eliminating electrical signal loss and delivering instantaneous feedback critical for throttle response diagnostics and tuning validation. The 0–35 psi range is optimized for street and mild-to-moderate boost applications, providing precise needle response and easy visibility across the full pressure band.

This mechanical boost pressure gauge is suitable for turbocharged four-cylinder and six-cylinder platforms, supercharged V8s, and diesel builds where boost pressure under 35 psi is standard operating range. Installing a quality boost gauge allows you to dial in your system confidently and catch mechanical issues before they become catastrophic.
