No Centrifugal Supercharger has boost right away.
A Centrifugal Supercharger is not a Roots supercharger.
Maybe you are confused on the two.
A Roots will have some pressure ratio change from off-idle on.
A Large Procharger will make good boost at about 1/3rd to 1/2 of its rpm capability. PM Brian H (as he ran Procharger stuff for years and he will tell you the same.)
So Boost does not happen right away (like a roots) BUT if you are leaving at 6000 rpm then the boost
will be there at that point. Deal is you have to transition from idle to that launch rpm first.
Read some web stuff about the differences between a roots and a centrifugal supercharger or a Turbo.
