Looking well, do you think a nice and smooth diffuser is optimal for performance? I made mine way steeper with the idea to convert the rotating gas stream into a less rotating turbular flow, with the idea that turbulent flowing fluids are taking less energy than spiral flowing..

Another theory is that when the fluid is rotating and you have a smooth diffusor like you it will create a lower pressure after the turbine wheel, which offcourse is good..

I noticed this aswell Rub and thought that in adition to what you have mentioned it will slow down the flow to the 2 centre tubes and give a more even flow through out each cylinder.
