2-5/8in Boost 35psi Mech

The 2-5/8in Boost 35psi Mechanical Gauge from Autometer is an essential diagnostic tool for automotive enthusiasts and mechanics working with forced induction systems. This mechanical boost gauge monitors turbocharger and supercharger pressure in real-time, providing precise feedback on engine load and system performance without relying on electronic sensors or engine computer readouts.

Equipped with a precision bourdon tube movement, this gauge translates boost pressure directly into needle deflection across a 0–35 psi range. This design eliminates dependency on fragile electronic senders that can fail under extreme conditions. The 2-5/8-inch dial face fits standard instrument cluster openings and aftermarket gauge pods, ensuring straightforward installation in both classic restorations and modern performance builds.

Ideal for turbocharged or supercharged vehicles, this gauge allows for instant response with zero lag, which is critical for catching boost spikes or sudden pressure drops. The robust housing is engineered to withstand the vibration and temperature fluctuations common in high-output engine bays, making it a reliable choice for those who prioritize engine safety and performance.
