Anyone with Pertronix Igniter 2?
#1
Ok guys I think the time has come to upgrade the ignition to the Pertronix Igniter II.

Other than being more reliable than having points, is there a performance increase from stock?
Do you recomend installing the FlameThrower coil also?
When installing the Flamethrower coil, are there any modifications that will have to be done or does it just replace the stock coil?
I remember reading about some resister that has to be removed?

Thanks for the info.

I upgraded to Petronix in my 73 Convert, but it is a six banger, 250 CID. I did the Flamethrower Coil too. The only things I remember removing were the points and condensor. Nothing about a resistor.

I've read on another forum that you can use the stock coil, but you loose some of the performance.

The car has idled and ran better with the Petronix than any time that I have owned it since 1974. Good Luck!

You will burn up the stock coil after a while with the Petronix. Ask me how I know. Sad

Did you replace it with a Pertonix or another stock unit?

i'm running a pertronix II with a stock coil. Its a cheap made in china yellow top coil, knock on wood I've gotten 4 years out of it so far.

So i've run points, P1 and a P2.

with my ignition system in good shape i never saw a difference in performance.

now when i ran a high power coil there was a little more power over stock.

Stock plugs, stock gap, stock wires, stock distributor, and the points and p1 and p2 all ran the same.

but what is the difference?

The problem with points will always be they need adjustment, the more cheaply made the points are the more it will drift.
points can't take a high powered coil either, that said its harder to maintain the ignition at peak performance for a long period of time.
A high powered coil will also deteriorate the resistance wire, the plugs, the ignition wires, rotor and cap faster.

installing an electronic ignition removes drifting points out of the Equation as a maintenance issue.
since the electronic ignition switches the coil firing from analog to digital you can run a higher powered coil if you feel your spark isn't hot enough. With points the higher voltage when the contacts come together just wears the switch out faster.

installing a P2 gives you the benefit of adaptive dwell which adjusts spark timing at high rpms to try and prevent misfires, with points at high rpms the points can skip and cause engine misfires. it also autosenses startup and its suppose to make cold starts easier.

personally i never saw a performance difference from a p1 to a p2 as far as cold starts. nor did i have an issue with my points skipping however i don't drive around at 5000rpms 99.9% of the time.

I think the p1 is more reliable then a p2 the p1 is older technology while the p2 uses a microchip inside its much easier to damage a p2 then a p1. of course either a p1 or a p2 could die out of the blue and leave yo stranded so everyone carries a set of points in the trunk just in case.

I've run a p2 for the last 3 years continuously and pretty much i forgot it was there.
the year before that i ran points and a p1 unit, i had a magnetic sleeve go bad on the p1, and used the points for like 9 months straight, and i was constantly having to make adjustments to the points after long trips, it would just drift all over the place.

there are other electronic ignition systems, people love Malory or Accell systems.

I've been happy with the p2 so far.

I have a new Pertronix Ignitor II but I got the complete billet Distribuator. The old Dist. was tired and worn out, so the little extra money was well spent on a complete unit. I also have a 45,000 volt epoxy filled Pertronix coil but haven't installed it yet. I also need to research the resistor wire issue so I can be sure a full 12 volts is hitting the new coil.

Thanks for the info guys.

This morning I'm going to pick up the Igniter II and try it with the stock coil and see how that goes.
