I'm very familiar with the numbers the T3 is capable of (been working with skinnee on building an estimator for it) and without giving too much away without his blessing, I'll say what I can about the performance. In a single loop config, its PQ curve is similar to that of the Koolance D5 top. But when 'unleashed' and using both flowpaths (i.e., parallel), the PQ curve is more like the EK's or Detroit Thermo's....and that's not a property of being in parallel, that's just the fact that the top performs better when all ports are used (i.e., as it was intended).

My guess is that a loss similar to the loss that exists when going from LILO+TITO to just LILO or TITO will also exist (though for a different reason) on another top that uses a Y-split.

As for the example that skinnee gave, it's a pretty bad one in the grand scheme of things. Loops that are all-inclusive and have restrictive components will see a big boost from the T3, especially if you isolate the CPU block.

Dual system scenarios also work well
I think i've got it now seeing what Boxgod posted got me thinking, if there is a parallel loop setup where you Y out of the pump then Y back into the res being that water is incompressible you will see no gain. However if you Y out of the pump and your res has dual return ports the res can act as an expansion chamber of sorts. So in effect due to the restriction in the loop the water doesn't need to compress, if you put a Y on the outlet of the pump the water will by nature fill both sides of the Y due to the restriction of each loop and the water taking the least path of resistance.

The least path of restistance will always be the loop that is not full, the problem comes in when you add a Y going back into the res you no longer have any room for expansion therefore you will never see any gain as the volume of water flowing through the 2 loops going back through the Y remains the same because you cannot fit more water through that Y going back into the res.

However if you have two lines going back into the res then you can effectively have 2x the volume of water flowing through the two loops combined when the pressures equalizes and both loops are full.

I can see it in my head but it's really hard to explain what i'm thinking lol not sure if any of this makes sense
