Silly question, but I’ll ask it anyway.

heaudio12329 posts03-03-2020 4:58pmI am not aware of any fixed resistor in ages, and copper, not in forever except for racing, and even then you want to control the 
Most domestic wire is not simply a fiber glass core covered in carbon filled latex. Most are variable spaced fairly high resistance stainless wire. They variable spacing is so they can have consistent performance independent of wire length, hence why today you buy vehicle specific wire sets (or should).
Don't pick some random site on the web for your information. Most mechanics won't have a clue about the inner working of spark plug wires.

And you are a mechanic? I am. The reason for the carbon wire is radio interference, primarily emergency. You can still tell when someone is running multi strand wire, pull up beside them you'll hear it through your AM or FM radio stations. Most hot rodders that have MS wire DON'T have or use a stereo while running.  The old MS wire was OK speaker wire at best. A LOT of insulation for HIGH voltage 15-25 for the old point/condenser style, and 50+ for HEI, can really bite you.

Better off insulating a piece of solder, hee hee.  I mean where do you people come up with these ideas? LOL 

It's the thought that count's RIGHT..

spark to prevent fuel cavitation.

Cavitation in a hydraulic term referring to a pressure drop on the suction side of a hydraulic pump, where pockets of current atmosphere, form bubbles. Those bubbles actually collapse and carve out the cavity pre chamber to a pump. Same with hydraulic Motors, You can hear cavitation..tearing up a pump.. restricted lines, pump and motor killers.

The spark is controlled to prevent air/fuel PRE DETONATION. ..A fuel KNOCK or RATTLE is caused normally by a carbon build up that gets so hot it PRE DET. due to excessive advanced timing (BTDC) a Fuel rattle. Shutting off an continuing to run (DIESELING), again glowing carbon, particles with a fuel and air supply, BUT NO controlled spark, Firing under pressure, dieseling.

The definition of a diesel is simple 2300 psi, it will not be a diesel without it.  NOTHING ELSE.. 2300 psi.. You can obtain 2300 psi a few different ways... Different story..... See learn something every day...

I know I use to teach engines gas/diesel 101 201, 301. Yup yup
That was a while back...NOT MOTORS ok....ENGINES..

. 2300psi is a relatively meaningless number that represents a very specific set of conditions w.r.t. initial air temperature and fuel type. It is not, in any way, form, or function a definition of "diesel"   (nor have anything to do with this conversation.

The conversation no, the meaning yes. An engine that fires under compression combustion, (diesel) requires 2300 psi to achieve that.
Whether by charging the combustion chamber with ADDED air and then by piston compression or by simply, sucking it in, close the valves and compressing the chamber. Fuel is added via injector at a given time, and a given fuel pressure, either BTDC, TDC, or ATDC. This is an analog system, PT as in cummins. (yes oversimplified answer, but I'm a simple Retired Master HD Mechanic) YES it is old school..
The spark plug thing was at best oversimplified. I do appreciate you updating me on the wire thing... Interesting. I'm was a Detroit, Cummins, Deutz and Cat engine certified. Yup Yup.  Been a while though, I'm retired now. thanks for your input though. 

So the new spark plug wires sound like a 20,000.00 speaker cable in the making. After all the stuff I read about, networks, tungsten, white gold, nickel silver, why not add SS and carbon to the mix? 

Respectfully and with regards

off the subject but what the heck. 

  This is true about dieseling and in fact if you put a drop of oil on the back of a high performance air gun pellet, the heat generated by the rapidly compressed air in the chamber will ignite the spot of oil and increase the pressure of the shot..., maybe to the point of splitting the barrel.

Yup all kinds of crazy things, and their worried about (gunpowder) guns on the street. (or nitrocellulose is the proper term). Crack me up..


WHAT NOT TO DO!!!!! DON'T DO THIS EVER...

Oil on the end of a thumb, and turn up the o2 on an OX AC cutting torch
put your thumb over the end, NO THUMB. BOOM.  I saw the results in a training film. poor guys' thumb was just a stub. 

Still I don't think your off the spool carbon core spark plug wire is a good option for speaker wire. MS SS never know, may be the new craze.

heaudio12385 posts03-12-2020 3:40pm2300 psi is for a specific fuel type, mixture, starting air temperature, and rate of compression. It is a good rule of thumb in typical diesel engines with typical fuel.  Rep

Yup we are on the same page. If you think about it 2300 psi is the magic number. No matter how we get there. Clean initial starts, after that it's pretty amazing what the new stuff does (digital injector control)

But back to the speaker wire vs spark plug wire. may prove to be an
added sound nugget in a speaker cable construction, I mean tungsten, sc nickel/silver, sc copper, pure silver, pure copper, clades of all kinds
stranded, multi-multi-stranded, solid core, networks, dielectric material jacketing, all are now being understood. BETTER. I mean just listen to the quality of sound reproduction today vs the 70-80-90. Because of good cabling and SOME speaker designers

Just keep on asking questions, there's always a solution.
