Blown engines rely a great deal on the ability of the cylinder head and camshaft to move air through the engine; the compressor is tied to the front of the crankshaft. With a turbocharged combination, the air compressor is not tied to engine speed, so there is a little bit more latitude with what we can get away with.
You will see a lot of folks that say "bolt a bigger head on, and you'll make more power with less boost". Most times, that is a fact with a blown combination. And most (not all, but most) times, that statement is total fiction with a turbocharged engine. They are two totally different animals that are typically run in different ways on the racetrack.
