Question: How does a boost gauge work?

A turbo boost gauge is an essential piece of instrumentation that indicates the amount of air entering the combustion chamber. Air indication is measured as air pressure. The pressure of the passing air places pressure on the tube. The tubes internal pressure raises, and a deflection in the gauge is accomplished.

What does a boost vacuum gauge do?

A boost gauge is used to ensure excessive pressure is not being generated when boost pressure is being modified to levels higher than OEM standard on a production turbocharged car. A boost gauge will measure pressure in either psi or bar; many also measure manifold vacuum pressure in inches of mercury (in.

Do I need a vacuum gauge?

The higher the vacuum reading, the better mileage you would have, due to throttle opening. A vacuum gauge can also be an indicator of possible poor running conditions such as loose valve guides, leaky valves, etc. by means of a shaky vacuum pointer.

How often do Turbos need to be replaced?

between 100,000 and 150,000 miles Most turbochargers need to be replaced between 100,000 and 150,000 miles. If you are good at maintaining your car and get timely oil changes your turbocharger may last even longer than that.
