FBO or MSD what do you use?

Looks like I am late for this thread, as usual, but I will share some things I have seen with MSD. The Multi-Spark ignition system is a design that at idle, roughly 750-850 rpm, the spark plug will spark 3 times in 20 degrees of cam rotation when the piston is near the top of the compression stroke and just begining the power stroke. This is done to prevent fuel from fouling your plug and to get a more efficent system.

Now where some people get the wrong idea. The spark plug will not always spark 3 times! Just as Rumblefish360 said very early on the post, it will stop working at 3,000 rpms. Yes, roughly 3,000 rpms is when the system will only spark once and just act as a normal unit. I say roughly because the testing I did the multi-spark went away at 2400 rpms, only 600 rpms off, no big deal. At just about 1600 rpms the multi-spark went away to only 2 sparks for 20 degrees of camshaft rotation. This happens due to the magnetic field in the coil not able to collapse and expand, inducing voltage in the secondary ignition circuit, as quickly as the multi-spark unit would like it too.

Hopefully over the next week I can some how finish an idea I was brainstroming with a buddy of mine to where a regular coil, like the MSD Blaster 2 Coil in shape and size, would develop 100,000 volts of electricity to send to the spark plug. There is a reason to my madness, but I will not have a chance to test it until spring.
