Legion5, yes I also considered that the blower might be a restriction, but fact is that Boost in and of itself is a measure of restriction. Positive manifold pressure is simply air that can't get into the engine fast enough, and therefore, backs up in the intake tract. Every power adder that makes boost faces this restriction. By having the supercharger in place, we simply move that "buildup" of pressure to the intake side of the blower. The blower will then continue to do it's job, just moving air, as it would normally do. It shouldn't be thought of as a "block" in the system, because it's not a stagnant, non-moving piece. It is spinning at a very high RPM, and moving massive amounts of air. Therefor, it's not a restriction.
