Dual points for performance?

period correct performance ignition. If you're going to stick with points, at least it's optimized somewhat. Still limited to the max output the coil has

the alfa system is something completely different, dual points overlapping will create a hotter spark but don't expect miracles. The coil is still a limiting factor. I haven't seen any studies on whether coil life is shortened due to running them closer to maximum output all of the time. And of course, points begin wearing as soon as the distributor starts turning, so they are the least accurate method of controlling spark output

Seems pointless (no pun intended) since electronic systems will achieve and exceed the desired result. This just sounds like an opportunity to either burn up your tach, shock the piss out of yourself, or eat coils up frequently.

Thanks for responding, I didn't shock myself and my tach still works perfectly. When my coil fries I'll let you know.

Curious to know if it makes any difference at all. I'd pull those plugs in a few miles to see how well or poorly it is burning fuel. You don't want the long duration spark to create a lean running motor, you can drop valves that way. If it is a little lean just tune the carb.

Huh, that was ever a thing?

No reason it wouldn't work, but wouldn't the 2nd spark be kinda small?

My understanding of electronic multi-spark systems is that they are only effective at low RPM. I don't see how this wouldn't be limited by the same factors.

Alfa Twin Sparks? Absolutely. They had eight plugs and a distributor with eight fittings:

No i know that twin spark is and continues to be a thing.

i meant using both sides of a dual point ignition in parallel.

dual points don't provide dual spark, just one
