Chuck, according to the guys at RP (who have been selling Jacobs for many years) you can run the fc1000 on a stock coil, evidently it's not nearly as powerful as the older versions so there's no need.

I don't dispute that the HKS TP is a solution to the ignition mods required for high boost high rpm reliable operation of the rotary. I have one on my car.
But I do have a question/thought .....
The interesting thing about the HKS TP, is no one, that I am aware of, has done the research and has posted there findings here as to exactly what the HKS does from an electrical circuit perspective. It is a fact that this expensive box it is wired in parallel to the wires between the igniter and the coil (not in series). Based on that fact it can not "replace" the stock signal to the coil it can only modify (extend or amplify) it. I have assumed for some time that it is just a large capacitor and a simple circuit that extends the dwell to the coils in high rpm conditions. Can anyone confirm what it does to the signal and why it is less damaging to the stock S6 coils? I understand that the Jacobs ignition burns coils because it does increase the voltage and extend the dwell to the coils.

Steve, Chris over at RP put a twinpower on an oscilloscope and determined that the twinpower works as a 'double strike' system, causing the plugs to fire twice as often in a given time period.
