Boost Gauges Measure Pressure Since forced air induction engines rely on injection of compressed air into the cars combustion chamber, and compressed air exists at a higher pressure than normal ambient air, boost gauges simply measure the pressure of the air flowing into the vehicles combustion chamber.
What RPM do turbos kick in?
A turbo spins very fast; most peak between 80,000 and 200,000 RPM (using low inertia turbos, 150,000-250,000 RPM) depending on size, weight of the rotating parts, boost pressure developed and compressor design.
