Friction is a concern in our loops, but you do want the 90 degree input for reasons of turbulence, I'd think. The outlet(s) would probably do better with swept style bends in flow. Anyone up to having curved flow outlets for their blocks?

I don't think it'd be significant in an overall system though, with modern consumer pumps like the D4/MCP650 and the DDC/MCP350. It was probably more of a concern with pumps like the Eheim 1048 pumps or the Rio "pumps". That's my guess. Anyone know what the headloss of a 90 bend is vs a swept curve and if it would be significant ?
