Bobo, from what I understand it wont increase the max flow rate, but for a given system the flow rate will increase over 1 pump? If you look at a graph of the flow rate vs pressure of a pump and a water block system, the system will run at the intersection of the two functions. Since the pressure is increased, the two lines will intersect at a later point of increased pressure and flow rate. Please correct me if I am wrong.
