Who sells 3.0 Magnacore kv-85 wires? part # 6514

[Reaper1]

There is something people need to understand about coils...just becuase they say they make X amount of voltage doesn't mean that they ALWAYS make that voltage. The discharge will only be as strong as is needed to jump the gap on the spark plugs. So, if the stock coil is keeping up with the gap you are running and the mixture is being burned correctly, a "stronger" coil isn't really going to do much. It should not have any real effect on other ignition parts' wear either. Now, if the stock coil is starting to NOT be able to jump the gap(high boost, lot's of N2O, or just plain rich), THEN you will see a gain.

I don't understand how a coil can effect dwell time. Dwell time is controlled by the points or the ECM. It is the amount of time the coil is saturated with electricity. Without having a secondary iginition control I just don't see how you can saturate the coil more than what it's being told. Now, that's where the MSD unit comes in...it overrides what the stock computer does and basically uses a capacitor to send the multiple spikes of voltage to the coil. After a certain rpm, there isn't enough time for this to happen, so it reverts to a standard dwell control and a single voltage spike.

Anyone tried Aurora spark plugs, i heard these are true 8.5mm. A TD guy say Magnacore is not real 8.5mm, so is that trrue? I like the Aurora name and will get them, just wanted to know if anyone tried one b4 since the topic is about spak wires.

What do you mean "true 8.5mm"????

The 8.5mm is the diameter of the total wire + insulation.

Magnacor kv-85 wires have a 2.5mm conductor. I am quite sure that Aurora's is smaller.
Magnacor recently started selling a 8mm and smaller wires for normal applications (similar to factory replacements).

Thanks Brent and irocelectric93. Another myth debunked. Those hotter coils do not trash caps and rotors more quickly.

Reaper1 that is also very helpful. Thank you.

mopar3.0, I think my MSD 6A at least helps keep my plugs clean. I don't know for sure, if it really makes my van pull harder, but I agree it does "feel" that way.

Well all the ford 5.0 coils are either the stock replacement or the "longer dwell etc" because they are all the same claimbed 48,000 volts as the stocker. And they cost 3x as much.

With a bigger coil you can open up the plug gaps
People might try .050 and .060ish gaps.

[Shadow24V]

im thinking of re-gapping my 3.0's plugs to .060 because the coils im using call for a .060 gapping STOCK on the 3.1 chevy they came off of that might help out a bit with power

[Reaper1]

OK, I just went and looked at some coils. They are talking about spark duration. This means they can output a certain voltage for a certain amount of time(kind of like a cam holding the valve open). Some claim to have a faster rise time...meaning they accept the primary voltage faster so they make the most use of the dwell that is being delivered to them.

Yes, with a better coil you can open up the plug gaps. The better coil can supply the needed voltage to jump the larger gaps.

[Shadow24V]

id think duty cycle would come into play in higher stress apprications (boosted etc) with a single coil setup. one advantage to DIS is that each coil gets more time to charge between sparks. so with a 3 coil DIS setup, a coil gets an aditional 2 cycles of charge time before it has to fire again.

Im really not sure myself, but Simon whos selling them says Taylor's wires offer 10.5mm but they're 6mm. Also these are durable when you try to take it off, it doesnt brake like Bosh etc... Its not my word, just try to see if anyone gives these thumbs up, their also Canadian so +1 for me.

Well thats just bogus then.

There is no such thing as a "real" 1, 2, 3, 4, ...8..10..n spark plug wire.

Thats total hype he is using. Read Aurora's website and their claims. Their claims backed up what magnacore says (that people, including aurora use fake spiral winding to create a low resistance reading on a 1 volt DC omhmmeter) so I am buying the magnacores that dont use a fake low resistance wire to trick people.

http://www.auroraelectronics.com/Spa...nstruction.pdf
Here is a cutaway of the Aurora plug wire. Its EXACTLY the same as almost any other performance plug wire except that its 400 ohms instead of the lower readings of other wires. The only thing good I see about these wires is the connectors look better. Otherwise, they use less fake low resistance wires (thats why they read 400 ohms not 50).

Magnacore doesnt use fake low resistance spiral wire. The actual wire in the middle (that aurora pretends is for structure) is the actual HIGH RESISTANCE wire that has the job of moving the electrical charge. All performance wires including magnacores have a similar center made of the same high resistance wire. They use it because it helps with suppression of interference. Magnacore wraps high resistance stainless steel wire around the core to help increase supression. Other companies wrap low resistance wire (to give fake low resistance readings - path of least resistance) and then since their wrap job DOES NOT help with suppression, they add the thick layer of EDPM insulation (aurora, MSD, Taylors, and EVERYONE else) because their spiral wrapping is fake.

Magnacors are just the center 2.5mm of ferrite conductor, the stainless steel wrap, and then a very thick coating of silicone (for heat resistance) Until the wires are 8.5mm or 10mm thick.

The auroras there (just like the MSD, taylor etc) have that extra EDPM in the middle because their cheap (cheap!) wrap doesnt do anything but fake low resistance. Then they add silicone tillt he wire is 8.5 or 10 mm.

Thicker wires dont have more conductor, just more insulation against high temps of your engine bay.

Most wire manufacturers fake low resistance because they want to pretend their wire is similar to a low resistance single core wire (which doesnt work with todays cars). They dont tell you that the low resistance is fake (the tiny low resistance wire they wrap around doesnt actually carry the 40,000volts from your coil)

[Ondonti]

Also, the reason why auroras have higher OHMS then MSD's etc is because Aurora wraps their low resistance wire tighter (more expensive and it provides a little bit of supression, but obviously not as good at Magnacore because Auroras still require the EDPM jacket). MSD doesnt even bother wrapping the wires close. they just wrap the low resistance as few times as possible so they can get the lowest resistance reading possible.

So if you want to choose a non Magnacor wire, I would pick the Aurora because they "sort of"do the right thing when building their wires, even though they could do a better job of wrapping their wires and use a wrap wire that is better at suppression then giving fake low resistance. I have no idea what their 3.0 wires would look like so there was no way in hell I was going to buy them.



Overall, I think the spark plug wire industry is very deceitful. Non magnacor companies pretend to have low resistance, yet all companies use the low interference, high resistance Ferrite core. Magnacor isnt honest that their center ferrite core (like all other companies use) is a high resistance conductor. Nobody is.

None of them are working on wires that are actually low resistance (on a real motor with thousands of volts so the fake outer wrapping doesn't give false readings) yet provide suppression.

[Ondonti]

So what I should conclude is that the performance wires are all the same, but I gave info above of WHY they are the same. I like the magnacores construction and their boots that actually fit. I like that I am not the one building them while still paying 80-100 dollars like some other wires. Auroras look like they have really really really good connectors but I have no idea what they look like so I was not comfortable buying them.

I cant say any of the wires are superior in performance........unless they had a larger center core......and I would put money that magnacor's core is larger then the other wire brands

[lookin]

Hmmm I think you are a good salesman Brent. I will stick with MSD though.

[Ondonti]

Well like i said, they are all basically the same unless one has a larger high resistance wire inside. Buy the ones that you like to use cause they dont piss you off to much :P

Seems fair to me.
