Has anyone had issues with these coils? I just replaced it late in the season. It is the original Flamethrower. I went with the epoxy filled because the oil filled should be installed vertically otherwise the oil will seep out of them when installed horizontally.

I just took the car out for an unusually warm winter day here in Canada. The car runs great until the car gets hot. Once there it starts to stumble and no power. I went home and replaced it with my stock coil - problem solved. The first Flamethrower coil lasted about 6,000 miles and this current one lasted about 1,000 miles.



If I run the stock coil, when using Pertronix electronic ignition I believe you can bypass the resistor. Is this correct?



Thanks guys

I haven't had trouble with them. The different ignitors have different requirements for the primary resistance. Are you using a coil that fits the requirements for yours?

Im with Charlie on this one.. Which unit do you have the original, the 2 or 3 ?

 I have the ignitor 2 with a Flamethrower .6 ohm coil mounted horizontal, no balast just a straight 12 volts at the coil, plugs set tiny bit over standard gap. No problems what so ever starts first time every time.

I have the Pertronix Ignitor 1 with the Flamethrower 1. It is mounted in the stock location. The car runs fine until it gets hot and then starts to fail. It has 2 months use on it. The guy at the speed shop told me to mount the coil on firewall to keep away from the heat, but I want to keep the stock look. The original stock Ford coil does not have this problem. Would hooking up the external resistor to the Flamethrower 1 be an issue. Would the external resistor help with heat issue?

The Flamethrower coil gets considerably hotter than my stock Ford coil. I may have to give up the performance for reliability.





Thanks all

Why not just use the Ford coil, they are probably the best stock coil you can have from the point/condenser era. I use an Ignitor I with a tan top coil and external resistor on my F600, been good for 12 years now.

Same here, i have 3 cars with ignitor 11 and flamethrower coils, 2 are mounted upright and one in stock location on its side , no resistors on any and had no problems.

I lost 2 or 3 Flamethrower I with Pertronix.  No ballast.  The coils would become very hot, and the minute the engine temp hit 180 the engine sputtered and died, wouldnt start for 10-15 minutes.  After things cooled down would start right up and do fine unless temp rose again in city traffic.  Went to a Pertronix II and Flamethrower II and no problems.

You wire it differently with the resistor than without.

And, you know, my Pertronix coils are at least several years old. It's not impossible that they're having issues with a newer batch.

Basically all of the original Ignitor units have to limit the coil primary OHMs to 1.50 or more. If you use a coil with more OHMs it doesn't care - and if it is an original coil or an original plus a ballast resistor, its just more protection for the grounding transistor - less AMPs to switch. Protecting the transistor is a necessity for long life of an Ignitor I system. Finding a coil that takes the heat of direct attachment without a ballast resistor is another.

He might be able to use a cylindrical coil intended for use with the Ford Duraspark II system - they are less OHMs than the standard points coils but more than the Pertronix 1.5 OHM minimum by a safe margin. They are also designed to be used with fixed dwell / transistor ground systems. In the stock Ford arrangement they are fed through a 1.35 OHM resistance wire - but if I could find one as a salvage part (with the mating wiring clip), I might try it out with full voltage.

MSD has a ballast resistor that is .88 OHMs and it might be used to to "tune" a 1.5 OHM primary coil to a slightly lower AMP load - less heating. So long as it is wired as the diagram Charley attached - it won't cause problems with the Ignitor itself. As Nat remarked early on - the performance will be lower the higher you go over the 1.5 OHM minimum - but if reliability is suffering, its not worth the hassle.

Nat;

I run the Pertronix II ignition with an MSD Blaster coil and no ballast resister and have had no problems for the past 3 years.
