When rebuilding your engine make sure your pump has to correct tolerances. Test the end float, many people do not, and they wonder why they have low pressure. Replace if wear is detected between rotor and pump body. 
These pumps deliver plenty of pressure for Street and mild performance use. You can increase the flow/pressure by radiusing the inlet and outlet of the pump.
