I definitely don't know all the reasons why boost doesn't actually translate that way but I do know that TT is the efficient boost option. It is essentially free energy because it is using the actually exhaust of the engine to spin the turbine. The only problem is you have to wait for the exhaust pressure to build for the TT to spool. SC on the other hand uses engine HP because the turbine is spun by the engines belt system which, while creates boost, also takes HP to do. Typically the main benefit of SC over TT is earlier boost times. The disadvantages is that you will typically not have as high gains from SC then you would a TT. Main reason being is becuase the engine itself it working harder just to spin SC.
Like i said above, sometimes Centrifugal SC and TT produce boost at around the same time though.
