0-Ohm wires...

I would like to hear others opinions on this... Is it worth the 70 Bux to see if they are lying for the length of wire we have...

I know our wires have a decent amout of ohms especially the front set vs the rear, so I wonder if these would help out at all.
I'm not to keen on the green though...

I would not waste my money. They have to have some resistance, it is imposible not to, all wires have some resistance.

Yes but they have a video where they test stock LS7 wires and they are 800 to 830 ohms and then they tested theirs which came up as 0.1ohms... Kinda hard to fake that expecially when a Ohm meter says OL when not hooked up to a wire.
Granted these are 8" wires but thats my question... if they are 0 ohms or 0.1 at 8" they gotta be lower than the 200 ohms per foot for typical wires.
Here is a ohm test I found online

Zero k ohm means less than one. And its per foot. 7k ohm wire, 2 foot long, 14k ohms.

We are not talking K ohms here... unless they pull a fast one and switched the scale on their meter. I doubt that. We are talking straight ohms. No wire should have 7k ohms of resistance in a foot.

I just pulled number 2 wire which is my longest and tested it. This is a brand new set of Accel Super Stock Spiral Core wires I got 1.499K ohms so that ends up being about ~549 ohms per foot since the wire is right around 33" long, not including the clips.
now if they can drop that number down to the 200 ohm range overall for 33" or even less that would be one hell of an increase in spark to the front bank.
They sell my wire at 500 ohms a foot too so thats pretty spot on to what I got.

I was just giving an example, albeit a bad one. Lowest ohms per foot I've seen is around 50. With coil on plug ignition it really makes a difference.

Not any longer if you look at the link I posted.... thats 2 ohms for about a 8-9" wire...
Fixed my link in this post...

So yes I know its a per foot addition deal, but thats my point, if you can get a wire that is 5ohms a foot... thats less that 15 ohms for the LONGEST wire on our cars and thats less than ANY of the wires currently in place on my car. Its gotta make a difference as you noted the coil on plug does affect it some.

Well there are a bunch of arguments out there that the way a spark is delivered to the plug is not affected by the resistance of the wire, but it has to have some sort of affect on it.
I guess the only way to tell would be to pick up a set of these wires and dyno my current Brand New set and then this new set... I would not wany to test it on any other wire due to simply the age of the wire can cause issues.

I don't think you're going to see any real HP gains. When you eliminate the wire all together then you will see a difference. You might see an increase, but that's because you're replacing a set of used wires with new ones. When you have 45k volts if potential, you're going to burn the carbon out of the strands, solid or spiral. That's when you see the performance fall off. The same goes for spark plugs, they just burn out and you loose power. But I'm not telling you anything you don't already know.
What I look for in a set of wires is how its manufactured. If they use cheap wire, and cheap fillers the pulses don't skin the core as efficiently and you don't get as good of a spark.
If your burning plugs up all over the place, then is recommend a lower resistance wire, but if your setup is reliable then I really don't think you'll see gains. IMHO of course.
If you really wanna do the test, buy a new set of what you already use, and a set of the 0 ohm units and put it to the test.

I guess you missed the point that I already have a brand new set of Accel Super Stock Spiral Core wires, which is why I said I would probably the the best candidate currently since both sets of wires would be new.

No I read that. That was for general info for anyone reading it. If you get a milage or HP increase from changing your wires, its because you replaced used wires.
Like how those wires claim they increase HP, only because your other ones are burnt up.

The lowest I found on a set made for my 90GT was 7 ohms for the longest wire and that was Bosch. I found that the Delco had 15 and the Omni Spark had 22.
I run BWD wires now because I can't get the Bosch. The BWD are 10 ohms.
Those Omni Spark are real coil killers, that is way too much.
Ohms are resistance to flow. What you getting by having lower ohms is a more powerful spark: better burn. No you will not see much more HP, but that is not the point. Efficiency is the point. A cleaner burning engine can open doors for a little more tuning on a multi spark set up.
As for 0 ohms I just don't see how you can do that. There has got to be some.

I have a hard time believing that you have wires from Bosch and Delco that are 7, 15, and 22 ohms when the lowest that Accel MSD and others can achieve is 200 ohms a foot.
Also the sale is near 0-Ohm, I guess I should have specified that since there is so much confusion. I want to see what their Ohms would be for our longest wire and going by what I've seen they are about 2-3 ohms a foot which would make ours 8.25ohms or so.
Double check your measurement and make sure thats not K ohms

I don't know how objective this is, but it might be worth a read..
