Blower RPM = Boost. I know some guys want to say a 6 lb lower still adds 6 lbs on a HD. And the HD upper just yeilds 2 lbs less net boost than a L, and therefore a 6 lb lower on a HD is equivalent to a 4 lb lower on a L, but then you'd be saying that a 6 lb lower on a HD turning 14,538 RPM's makes the same net 12 lbs of boost as a 4 lb lower on a L turning 15,230 RPM's. 692 RPM difference in blower RPM is certainly worth some amount of boost! So a HD can't make the same 12 lbs net turning 700 RPM slower! Nothing magical there The L combo with a 4 lower is turning 11.5 times more per second than the HD combo with a 6 lower, that most certainly creates more boost.



I definitely will! Just giving it a few days in the "discussion" area before its stuck and forgotten about lol
I just got into this little argument the other day....it is hard to argue with numbers.
