So boost is measured by how much the air is compressed because when the volume decreases the pressure increases and if you increase the volume of air and compress it you have a higher boost pressure? Or is boost pressure how hard the turbo is working to pump the air? I read that on a website? Is this correct? How can you be producing more boost when at lower air masses than at higher air masses? Example 9psi@30lb/min 20psi@20lb/min How is this possible? Is it becaus eof turbine shape, design, weight, material do all those factors come in play? When there is more pounds of air flowing wouldnt there be more boost because more air is flowing so more air is being compressed? Or does it depend on volume rather than pounds? Can you please explain this to me in detail?

'Boost` for automotive superchargers is generally measured in PSI over ambient.
(Aircraft use direct measure of manifold barometric pressure in inches of mercury.)
'Boost` is only an indication of total power produced when compared to the same engine at the same RPM.
