Haha I remember finding that thread somewhere and thought Mike's comment was funny as hell.
I think it can generally be true to an extent. However I also feel that if a supercharger is TRULY pushing the same psi as a Turbo there shouldn't be a difference. MY friend has an 8 pound pully on his procharged mach1, and his boost gauge isn't working yet for some reason. We went to dyno tune at a very reputable mustang tuning shop around here and they hooke dup their boost gauge which showed he was only making 5.5-6 pounds. His supercharger is more like a belt driven turbo and not manifold rotor style like many other superchargers (TRD etc.). I don't know a lot about boosting mind you, but it seems to me that it just may be improper readings etc. that lead to theories that turbos are better than superchargers.
What I'm trying to say is that air is coming in under the same pressure so I don't understand how ti could work differently. Now which one can create that pressure more easily is openly up for grabs as turbos do a damn good job. Also remember lack of turbo lag with superchargers, and a lot of intake manifold replacements now have valves to realease excess air coming in eliminating parastitic loss.
I know this is all a shot in the dark as I don't know what I'm really talking about, but I'm just looking at it from a physics standpoint. If air is entering your engine at a specific pressure, does it really matter how it got there? This is where intercoolers can come into play so I'll rephrase that to mean the same tempurature and pressure. With physics, does it really matter just how it got there? I guess the recirculation plays into how fast he turbine in a turbo can create that boost as compared to a supercharger, but whatever. I don't think I'll ever fully understand boost.
