An afterthought....it should be linear since the blower is pumping in at X and the pots are sucking it in at Y - both are "fixed displacement" volumes and both are linked to the crank....so the "inventory pressure" within the plenums is only influenced by any changes in the ratio between the two - ie: speed the charger up and you increase the inventory pressure because the SC is puming it in faster than the pots can take it way.
hmmm...need more afterthoguhts
