A boost gauge is a dashboard mounted instrument that indicates turbocharger or supercharger boost pressure in an internal combustion engine. A boost gauge is mandatory when boost pressure is being modified to higher levels than OEM standard on a production turbocharged car. Boost gauges will measure pressure in either psi or bar and many also measure manifold vacuum pressure also in inches of mercury.
