I worked out pretty soon, that building the turbines straight onto the reactor was the best way. I had a similar setup to Curunir's setup, but I had two turbines on top of each other (with the mandatory gap in between), I would have had them on different sides, but space was an issue. this however turned out well, because I was able to back both turbines onto a single tesseract.
The reactor started out with 3 rods, 6 high, in an 8 x 7 x 5, with the turbines 16 in length, with 3.5 coils.
With this configuration, I was getting over 18k per tic on each turbine.
I recently watched a video where they had turbines built in a 7 x 7 x 16 configuration, that allowed them to put in more blades and get ~24k per tick.
Although this configuration yields more per tick, it requires many more pieces to build.
Reading a bit more, if you orientate the turbines vertically, you can go as far as 32 rather than 16 in the horizontal position.
2000 mb / 25 = 80 blades, and from testing, more than 80 blades makes no difference.
My latest design consists of 2 turbines each with 20 rotors with full blades (80 blades)
4 full enderium coils plus one coil with 5 enderium blocks only.
27 x 5 x 5. RPM: 1796.7
RF/t: 29362
@ 2000mB/t
I believe this is close to, if not the most efficient turbine configuration.
I've updated the reactor with 3 rods 9 high, plus enderium coolant, I'll modify this later on, so I can have both turbines share the same tesseract again.
I've also attached two railcraft Steam Turbines direct to the reactor, which means I have to add water to the system, using upgraded extra utilities liquid transfer nodes.
I'm sure I can redesign my reactor to get more efficiency, currently around 0.080 fuel usage 445% efficiency and I may have to get into the computer programming side of things, to counteract the on/off actions of the railcraft turbines, but its working fine ATM.
