Bigger blower = more power?

[QUOTE="LT1Porsche, post: 15954754, member: 24604"] Using this theory your HP gains with a bigger blower at equal or less pressure would be a result that could only explained by temps and the HP gains would mostly be seen at higher boost pressures. That’s the side of the argument I’m not agreeing with. 15psi from one blower is not equal to 15psi from every blower as far as volume because that would leave your HP gains only to thermodynamics and efficiency characteristics of each blower. Totally ignoring CFM capability. I’ve seen bigger blowers make more power on less PSI. Those gains cannot only be from temp and parasitic loss. Has to be a volume. With turbos there is a scanvenging effect caused which increases velocity through the ports which is said to be where most of the increase in HP comes from in that area. Now taking that out of the equation bc we aren’t dealing with turbos. [/QUOTE]
