Description
The Speedhut 2-5/8″ 30inhg-0-15PSI Boost/Vac Gauge w/Warning (R25-BV2-REV) is a vital instrument for monitoring the performance and health of turbocharged or supercharged engines. This gauge accurately displays both intake manifold vacuum and turbocharger/supercharger boost pressure, providing crucial real-time data to the driver. Equipped with a high-quality 3-wire military-grade transducer, this gauge ensures precise and reliable readings within a range of 30 inches of mercury (inhg) for vacuum to 15 pounds per square inch (psi) for boost. Its standard 2 5/8 inch (68mm hole size) makes it a suitable fit for many aftermarket gauge pods and installations. The integrated warning light adds an extra layer of protection by alerting the driver to potentially harmful pressure levels.
KEY FEATURES AND BENEFITS:
- Accurate Monitoring: Provides precise readings of both boost (0-15 psi) and vacuum (30inhg) levels, essential for understanding engine performance.
- Reliable Sensor: Features a 3-wire military-grade transducer, ensuring accurate and consistent pressure readings under various operating conditions.
- Early Warning System: Integrated warning light allows users to set pressure thresholds, providing a visual alert if these limits are exceeded, helping to prevent potential engine damage.

HOW TO USE:
- Mount the Gauge: Securely install the 2 5/8 inch gauge in your desired location using a compatible gauge pod or mounting solution. Ensure the 2.67-inch (68mm) hole size is appropriate.
- Connect the Pressure Sensor: Locate a suitable vacuum/boost source on your engine’s intake manifold. Connect one end of the provided boost/vac hose to this source and the other end to the included pressure sensor.
- Wire the Pressure Sensor: Connect the 3-wire cable from the pressure sensor to the back of the gauge, ensuring correct terminal connections as indicated in the product’s wiring diagram (if provided).
- Connect Power and Lighting: Attach the 3 ft power and lighting harness to the designated terminals on the back of the gauge. Connect the power wire (typically red) to a switched 12V power source in your vehicle. Connect the ground wire (typically black) to a suitable ground point. Connect the lighting wire (often orange or similar) to your vehicle’s lighting circuit if you desire the gauge to illuminate with your headlights.
- Set the Warning Threshold (if applicable): Refer to the product’s instructions on how to set the desired boost or vacuum level at which the warning light will activate. This usually involves adjusting a setting on the gauge itself.
- Verify Operation: Start your vehicle and observe the gauge readings under various engine loads to ensure it is functioning correctly and displaying accurate boost and vacuum levels. Check if the warning light activates when the set thresholds are exceeded.
