Will that harm a normal engine (10:1 w/forged pistons)? Will it burn the fuel any better or does normal combustion take over? Does the Pertonix coil need its own system?

It will help burn the itty bitty stuff that's hard to ignite. Unless you have a problem it shouldn't be significant. If you change WHEN it starts the burn you're going to have a problem. That means you're advancing or retarding the timing. Let it burn into combustion. No problem there. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon
