Whether you are fine-tuning a turbo setup or keeping an eye on engine efficiency, accurate manifold readings are essential. The Speco Vacuum / Boost Gauge is ideally suited to turbocharged street machines, supercharged builds, performance petrol vehicles, kit cars and hot rods, delivering precise real-time insight into both engine vacuum and boost pressure. Featuring a dual-measurement dial, it clearly displays manifold vacuum and forced induction pressure on a single face. Operating purely mechanically via an internal Bourdon tube, the gauge reads manifold air pressure changes directly — eliminating the need for electronic MAP sensors or complex wiring modules.

  • Dual Vacuum And Boost Monitoring: Measures both induction manifold vacuum and turbocharger or supercharger boost pressure.

  • Wide 270-Degree Mechanical Sweep: Expansive needle movement enhances accuracy and readability across the full range.

  • Vacuum Scale (VAC): Left-side scale reads from 0 to 30 IN-Hg (inches of mercury) for monitoring engine load and efficiency.

  • Boost Pressure Scale (PRESS): Right-side scale reads from 0 to 30 PSI (pounds per square inch) for forced induction performance tracking.

  • Purely Mechanical Operation: Utilises an internal Bourdon tube to directly measure manifold air pressure shifts.

  • Real-Time Engine Feedback: Provides immediate visual indication of boost response, throttle input and engine condition.
