Hey @
thejuggernaut Without the Dryside upgrade you will not get the increased flow, by simply upgrading the QD Driver and WetSide. You will, however, get the increased efficiency, noise reduction, and durability by switching the Driver and WetSide.
Increased flow (MP40wQD) will only come from the addition of a MP40wQD DrySide. Although, if you are happy with your current flow amount and are more concerned with decreased noise, the Driver upgrade is for you! And only at a cost of $75!!
Upgrading all three pieces of your MP40wES will be $349, which is the exact cost of a brand new MP40wQD. Upgrading the WWD will cost $473, MORE than a brand new MP40wQD....
Check out the "Upgrades" page from EcoTech Marine
Upgrades « EcoTech Marine Store
And the QD Information Packet (pg. 10-11) for upgrade performance information.
