Flow comparison in high restriction loop with various blocks, pumps and fittings
In my quest for a decent loop flow I've experimented a lot with various pumps (2xD5, 2xD5 Strong, 2xDDC 3.25, 3xDDC 3.25), fittings setups (from extreme BP fest to just straight compression and tubing), SLI configurations (parallel, serial, EK bridge, BP Crystal Link), blocks (full mobo to nothing, EK wave GPU design to new more restrictive) and this brought interesting results which I think are worth sharing.
I thought it would be good idea - perhaps helpful to some - to combine all this results in a single table so the information is easily accessible in one place - rather than scattered in my worklog (thanks to eXa for the suggestion).
All in all from this data you can get very rough idea what you might expect with change of pumps, SLI configuration, removing fittings or blocks as well as change in the EK GPU blocks design or how many fittings are needed for specific loops.
Note #1
Every single time the actual flow was different (read much worse) than the predictions in various flow estimators - so although many changes across each revision and the measurements being far from scientific reduces the value of data - the fact of being real life results increases it a bit.
Note #2
There was no flow degradation over time from version to version due to any sort of gunk in the blocks are algae.
Combination of distilled + PT Nuke + Acetal blocks + Black Primochill tubing + very little chance of reservoir exposure to the sun works very well in that aspect.
Note #3
Once again - this is far from any scientific measurements and testing, it's just sharing of results in my particular loop - so obviously your mileage may vary :)
Enough talk - here's the data:

Whenever change occurs between revisions - it's been marked in bold text.
