Description
The Speedhut 2-5/8″ 750mmhg-0-2.0 Bar Boost/Vac w/ Warning (R25-BV5-REV) is a precise instrument designed for monitoring the pressure within your vehicle’s intake system and the boost produced by turbochargers or superchargers. This gauge provides accurate readings of both vacuum, measured up to 750 mmHg, and positive pressure, ranging from 0 to 2 bar. Its 2-5/8 inch size ensures it fits seamlessly into most gauge pods or mounting locations.
KEY FEATURES AND BENEFITS:
- Dual Functionality: Displays both vacuum (750 mmHg) and boost (0-2 bar) levels in a single unit.
- Accurate Transducer: The integration of a 3-wire military-grade transducer ensures highly accurate and reliable pressure readings, crucial for performance monitoring and engine safety.
- User-Configurable Warning Light: The inclusion of a user-configurable warning light allows drivers to set critical pressure thresholds, providing immediate visual alerts if these levels are exceeded, helping to prevent engine damage due to over-boosting or identify vacuum leaks.
- Metric Measurement: The gauge operates on the metric system, displaying boost in Bar.
