Widely held notion that boost is a substitute for volumetric 
efficiency. Not exactly. Work done on the charge by boost increases 
charge temp - A given mass flow is a function of boost AND VE.
The better the VE the more mass flow for a given charge temp increase,
or a given amount of boost. Or the cooler the charge for unit boost.

However you figure it you will make the most power with the fewest 
trips to the piston store by starting with the best practical VE.
