Boost pressure is irrelevant, but airflow is not. Positive displacement blowers are hard to explain, but yes the bigger blower will make more power at the same power, more power at less boost. A pulley for a positive displacement blower basically dictates the amount of airflow going into the motor, and the reistance put forth by the motor determines the boost level. That's why if you run the same S-trim pulley on a 302, or a 302 with AFR 185's and a victor 5.0 intake the one with heads will see a few pounds less boost, but make more power.
