Regarding the addition of biasing magnets - what amount of speed increase are we talking about? I finally observed an increase but that gave me just 10-20 rpm extra per coilpair.

In my case it was about 150 RPM from 900 to 1050.
Try different strengths/sizes of magnets.
I used a probably 2-4 times stronger magnet than the rotor magnet(s).
Then you can add little ones on top of it. Make sure to use a 1-2mm spacer
between the core and the magnet. Experiment with distances.

@mondrasek:

I will try to replicate the Romero's waveform today and I will post my results here.

While running mine last night I found that I didn't need any spacers. I started with a piece of masking tape covering the core (magnetite/epoxy) and can get between 200 to 500 rpm increases (depends on magnet(s)). Then I tried with magnet touching core and seen same results. This could be because of core material?
Also I soldered ends to the 5 wire coil set to test them. One thing I seen before I quit last night is that with the wires in parallel and series - bucking I seen no cogging with load attached, the motor just speed up till I got scared and turned off.  Now same test with single wire coil and I get cogging and I will also see power to the load. There is something happening in the multi filer coil. Will be back in the garage to run more test today.
Peace

What do you mean with 5 wire coil set?
The bucking coil pair normally has two ends and maybe 4 wires alltogether if you count the interconnecting wires.
How is that connected?

@rawbush: Excellent!

And you know what? I believe I understand now what it is! The info has been available right from the beginning!!! Forget about the coils for now! What we wants is the core being CLOSE to saturation. That is what the biasing magnets do. In this situation we have the biggest field. The rotor magnet is attracted to the coil (this results in speedup), is being pulled close to the core and now it happens: The core is being saturated with the help of the rotor magnet (see coercivity of coil materials). At this specific point it is killing the magnetic flux, thus no current flow and no lenz drag. The rotor magnet can escape the coil freely and there is (virtually) unlimited acceleration. "Let the magnets do the work" and this is it! We were having it at our fingertips all the time, see image below!

Now if you want to loop you don't want rotor speed alone, but also get some power out. You'll have to find the balance between acceleration coils and power output coils. Of course the power coils will slow down the rotor but the acceleration coils can compensate the drag and keep the system running. Still it is a good idea to generate higher voltage in favor of high current, so using bifilar coils are a good idea anyway to get this looped. But the heart of the system is the timed saturation/coercivity of the coil cores.

P.S.: We're gonna make it!!!
