Just curious. Post your findings if you can.

here is what Steve at magnecor said:

"With a properly suppressed metallic wire the length does not mattter, as
long as the wire is fitted correctly (i.e. loomed up so it does not
touch anything). Unlike the factory wire, our wires do not have a
resistor in either the distributor or coil connector so there is nothing
that will inherently fail if it is fitted correctly.

We have made many wires for industrial applications where the wires are
30 feet long or more, and they work fine."

Yea. Electrons flow thru a wire like a straw full of BBs - when one goes in the end, another comes out the other end. I've heard the coil wire myth all my life and heard some really smart people discount it. It's nice to hear a knowledgable source confirm this. Magnacore is the last word in ignition leads. I trust them entirely.
Cass944, how about some pics if you get the time. I would love to see the progress on your build.
Good luck and keep us posted.

The Porsche factory set-up is supposed to be superior over carbon core supression cable, that's why its used on our cars. It still meets interference suppression goals, but is a more expensive solution than other cars used at the time. Copper cable we have can be any length, so long as resistors are on each end. Copper wire has virtually no resistance to BB flow, so its length is immaterial over the range of lengths possible within the engine compartment, is my understanding. The end resistors handle that. Just reading casually in this thread, but what makes us think our factory wires are not already resistance-matched?

Carbon core suppression cable used on other cars of the period also suppressed radio inteference, but had the disadvantage of different resistance to various cylinders because the resistance originates from the cable, so length matters.

Is there a third way that's better?

ive heard of cables being resistance matched to make SURE that the spark is the same across all cylinders. because obviously each cable is a dif length.

but in this case with it just being the coil wire, it shouldnt really matter

I would strongly suggest a full set of the magnacore wires. They are as economical as the OEM Beru and much better quality.

Nice!

Does it click into the coil and hold pretty well?

How much? I have the LR braided magnacores, one of em rubbed on the headlight bar and I always wondered if they would sell one or 2...

just an FYI, summitracing.com carries a ton of stuff for making your own cables as well.

So does the corner NAPA store, or any place that caters to drag racers and carries MSD parts. The key element is the crimper, a proper one is about $20.


Quick Reply: anyone ever make their own spark plug wires?
