Flamethrower coil

BQS4 · 06-14-2008

AS I'm not the brightest on coils, is the Pertronix Flamethrower coil the type that requires the resistor wire or straight 12v wire from the fuse box?

Depending on which Flamethrower coil you have determines if you require a ballast resistor/resistor wire. If it states on the package the ohm built in resistance of around 3.0, you don't need an external resistance. The coils that need the external resistor will say 1.5 or close. I like these 3 ohm coils better as you can run a straight 12v to them for use of Pertronix, and the wiring is quite neater. I hate the look of a ballast resistor

Keith;
I don't have the original box, is it marked on the coil itself somewhere?

Gene,

If you have an ohm meter you can measure the resistance. If its a 1.5-1.6 ohm coil then use the factory resistor wire. If its a 3.0-3.1 ohm coil then you can run a new wire to the coil.

On my coil, it lists the ohm value on the Flamethrower label

If I remember correctly, the Flamethrowers are available in both ohm ratings.

Which Opel are you working on? Your stable of Opels is a little large.
The reason I'm asking is that there are little tricks that might be applied for a faster coil saturation. ie higher rpms applications.

Dan;
I'm trying to keep plugs in Lou's Wagon from fouling out so often. She drives (if you can put it that way) to Cumberland Mall and back everyday. With idling in traffic, she fouls out plugs. John was over and I was talking to him about it. He said to open up the plugs to about .040" and use a better coil than stock. Which is what she is running. She is running a Pertronix ignition, but, that's about all.

opelspyder · 06-14-2008

On a 3.0 Coil, I think you need to run a full 12V to it, not the resistor wire. Or at least I have for Pertronix. A 1.5 you run a ballast resistor or resistor wire to. Or am I backwards here. The ballast resistor acts as a resistor wire.

Oh the green Opel wagon.
What spark plugs? Autolight,champion..
I thought we were working on Tony's GT at first.

Look into the download section the stock 3.0 ohm coil will pull a little over 4 amps. Guess what happens when you lower the primary to 1.5 ohms.

I think you are backwards and suggest you correct your post so as to not confuse people who read it later.

If that doesn't cure the problem I would look at getting the next hotter heat range plug.

The 1.5 ohm coil requires an external resistance, while the 3.0 ohm does not. If you want high voltage while cranking using the stock wiring scheme, get the 1.5 ohm coil.

There is a discussion about it here: http://www.opelgt.com/forums/1b-igni...html#post96737

yellaopelgt · 06-15-2008

Gene: If thats the coil I sent to you, its a 3.0 ohm.
BTW I have a bunch of those gaskets left over after my engine build ,so if you want them back,PM your address and I'll send em!
THANKS!

Yep, it's backwards so I will revise it for the other Keith
