Silly question, but I’ll ask it anyway.

. 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.

Well not trying that with either of my Feinwerkbau but you can give it a whirl....

of course you understand that perhaps besides Olympic Free pistol, air pistol is the most challenging.... or that might just be my ego talking....

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.
