Reading the Atlantis test made me remember the earlier article on WB testing that BillA did a little while back. In that article he changed the inlet size only on a water block and improved it's preformance. The chage he made was from 1/2" to one of 3/8" I think. I wonder how much of a boost the Atlantis would get if you changed the inlet barb to a 3/8" instead of it's large one it now has. A low cost improvement to a nice block. Perhaps a custom made barb that had a 10mm+ID size as the water comes into the barb but a short reduced area just before discharge. This would give a increase in the velocity of the flow while not restricting flow more than needed to gain the velocity increase. It would be interesting to see the results of such a test.
Anyone have a Atlantis they'd like to play with?????????
