im not trying to start an argument, but you are wrong my friend. the leadings are the ones that fire at the same time. take an FD for example, the leading plugs have one coil. two plug wires coming off of one coil and two harness wires going to it(12v+ and signal). then there are two trailing coils. each coil has one wire coming off for a spark plug and two harness wires going to it (again 12v+ and signal) now tell me how it is that the leadings fire independently based on that?

normally i would keep my mouth shut, but running a setup like you have mentioned kills power and on a boosted setup risks blowing the engine(i think you are still na) hell it may blow up an na, i honestly dont know. im just speaking from every car i have built, not a schematic someone drew up.

Actually, if you look at his schematic (I just did, to figure out what this was all about), he has the sensor that fires the leading plugs split to two coils, so as to fire both the leading at the same time, then the trailing fires as per stock through the distributor. I ran my ~400hp turbo bridgeport 12a this way (although through a pair of MSD boxes) for months. Your hung up on the fact that there's two leading coils and one trailing, which makes you think the leading is firing at different times, but what you're ignoring is that the trailing is still firing through the distributor, and both leading coils are wired to the same signal, and so they both fire at the same time. It's a spark power issue, not a spark timing issue, all the coils still fire based on the distributor's sensor.
