The XS has a moderate-high pressure drop, at about 6mH2O at 10LPM.

An Iwaki MD30-RZ can drive the XS at 10LPM. A Swiftech MCP600 at just under 6LPM. A Laing D4 at ~7LPM at 12V, or ~9.5LPM at 16V. An Eheim 1250 at around 5.5LPM. An Eheim 1048 at 4LPM. That's not counting other system resistances, which given the significance of the XS in the loop, have a fairly minimal impact on those flow-rates listed. As you can see, there exists plenty of options to get the block up to the upper end of the flow rate ranges that I test at, and indeed, that is how I manage to test at those flow rates.

I already know what the PD of the newer P2 refinement will be ahead of time, but I may change it depending on the outcome of some experiments with it.

Hmm, I wonder if Dyson will be mad about the block?
