In the instructions it specifically says to not use them. I want to know why?

I don't have any electronics, besides the 6al, the remote 2 step, and the electrical for lights, and I don't have a radio. Would I be okay to use them?
The instructions say that the wires could interfere with the msd box. But is that possible if I mount the box in side the passenger cab on the firewall?

Thanks

Are they Taylor?

Yes

Why don't you call MSD and ask them? Seems to me that would be the logical thing to do.

I've emailed them, many times. The only reply I have gotten is them stating exactly what the instructions say. I haven't called, I wasn't really too thrilled to call them after the email. I was just hoping someone could enlighten me.

It's a legit question. I don't know the answer but I'm sure someone will chime in with a more siantific answer than the one you received above.

I was told that the solid core wires emit significant EMI. It can be great enough to interfere with the MSD's electronics and triggering mechanism.

With todays wire technology, why would you want to use solid core wires?

They were a new set of wires I had bought for a mag. But I'm not using it anytime soon. So I swiped the wires.

Just thinking out loud here, wouldn't the firewall be enough of a barrier from emi? The box would be at the passengers feet. I realize it really isn't that far away, but with a barrier in between I thought it might help?

Summit racing has their Big electronic box with rev controll and my buddy got that and the summit racing distributor to go with it all and we tossed on some old acell yellow jacket solid core wires.
ran 11.50's never missed a beat.
I run the same wires on a pertronix points conversion.
I have seen certain tachometers act really goofy with solids.
The air gauged ones.. or whatever they call them.

You might create high speed misfires or the rev control may act goofy.
But i have not seen it in the above.

If i had them i would run them , but i am the test it for yourself type.

I run 10mm Taylor's, not sure if they're solid core. Msd 6al, blaster 2 coil and msd dizzy. Runs fine. I've never heard about it messing with msd boxes but I've heard about it messing with ecm's/computer control modules.

May not affect the 6AL itself but COULD affect the trigger and wires from the dist to the 6AL. These wires come twisted from MSD to dissipate some EMI and induction but MAY not be able to do it with the solid cores. Here's a good read:

My original 7AL units were required to run solid core wires.
When tracks went to modern electronics, they banned solid core and non resistor plugs with boxes because it wiped out their electronics.
MSD is liable for stray unacceptable RFI, they cannot tell you to use them, whether or not the unit would be affected.
Even Taylor directs you not too:
Available in two wire conductors:
1) TCW Wire Core is the ultimate solid core race ignition wire when RFI suppression is not a concern and when used with magnetos and point style ignition systems;
2) Spiral Wound Core (350 ohms per foot) when RFI Suppression is required for today’s complex multiple spark discharge ignition systems.
And they cannot tell you otherwise for the same reason, RFI.
FCC and anyone near your car will be mad, let alone the induced high frequency in your electrical system will erode contacts, connections, and deteriorate insulation.
If you try it, don't start it up near a newer vehicle, might be expensive.
If you want too try it, and you block my internet connection and then I might be .....
Oh, BTW, I have no knowledge if the newer units have anything in them that makes them require not to use solid core wires, only that they will probably not answer you for the above reasons.
Good Luck......

I've never seen any of these claims before.. got anything to back it up?
The most I've ever heard about solid core wires doing is making the radio sound weird- which was why they started selling wires with steel braiding on it that you grounded to the valve cover bolts to suppress most of the rfi noise..

 

[Jthomas]

~$60 isn't bad for a new set of Taylor's. I was just being stubborn and didn't want to spend buy new ones if i didn't HAVE to.

 

[SS_Dave]

You have to...

 

[Osmium]

there are some truths in the above posts.
I would have to say since the advent of digital chips and microprocessors in cars, they require a stable, constant voltage and constant current. most good products have EMI/RF filters in the power supply circuits. BUT NOT ALL.
Don't forget that in 12v DC systems, current works both ways. There ARE varying loads of current that get SOAKED UP through the ground, frame, block, body, and everything thats grounded.
Positive can be thought of as a ground. It completes the circuit, and also SUPPLIES needed current and amperage.
if you dont have any modern technology in the car, IE digital chips, only analog electronics, then run the solid core wires.
If it were me, I would use spiral wound for EMI and RF suppression. I wouldnt even plug a phone charger into a car with an unstable electrical system. cellphones shouldnt blow 20 amp fuses, but give me an iphone and i can repeat said performance until im out of fuses.

Claims? Experiences maybe better, while my experiences posted are older, I do have newer boxes that are very susceptible to RFI, why make your wires an antennae broadcasting in your car? As I do online, it is up to you to determine if the information given is relative to you circumstance.


My original 7AL units were required to run solid core wires.
1980 version MSD instructions, I did say original. FYI, still have a complete backup brand new in the box spare 7AL, crank trigger, coil, wires, plugs and accessories that I guess I could hook up, just don't really know if I would blow my phone trying to record it. Used this as an example because they did state solid core wires only at the time.

When tracks went to modern electronics(1980's), they (the ones I ran at) banned solid core and non resistor plugs with boxes because it wiped out their electronics.
Yes, my car was banned till I replace wires, 1980's, they now have better shielded timing systems. I will see if I can find a picture of the signs at the starting line, I think I have one buried somewhere.

MSD is liable for stray unacceptable RFI, they cannot tell you to use them, whether or not the unit would be affected.

They give you the proper installation, why jeopardize themselves?

Yes, I even had the FCC come see me when testing at our shop for disrupting emergency radio systems(Police). Also after changing to resistor components, all electrical problems on the car ceased. Lighting up fluorescent tubes outside the car was fun while it lasted.

If you try it, don't start it up near a newer vehicle, might be expensive.

Sorry, the big grin was for both sentences.

Oh, BTW, I have no knowledge if the newer units have anything in them that makes them require not to use solid core wires, only that they will probably not answer you for the above reasons.

I was going to add, but didn't, that I doubt a newer 6AL would be as bad as a older race ignition but you are still going to be broadcasting stray voltages into all you wiring and may cause problems. If you properly shield everything its a moot point for at least your car. I shield all trigger wiring.

Good Luck....
Do I have to back this up?
Good Luck to all!:thumbsup:

Modern spiral core wires are technically "solid core" in that they use actual metal wire rather than the old carbon impregnated string that was on these cars to begin with. Back then, "solid core wires" really were something like lamp wire, and even with points would lay down a static buzz that would kill all AM radio reception within 25 feet, along with the potential for interference with anything else electronic such as engine management computers. The benefit of wrapping the wire in a spiral is that it becomes a coil or choke that collapses the RFI field, giving basically as much conductivity as straight solid core wire, with almost none of the RF interference. Maybe there are still straight "solid core" wires for purely racing purposes, but why bother? Even a cheap set of Pep Boys spiral core replacement wires will conduct almost as much as straight wire, with none of the problems. And will be a zillion times better than what came on these cars to begin with.

 

[Schurkey]

wouldn't the firewall be enough of a barrier from emi? The box would be at the passengers feet. I realize it really isn't that far away, but with a barrier in between I thought it might help?

Solid-core wires will radiate EMI enough to screw-up television and radio reception for a few hundred feet. Back when I was in high school, everyone in the house knew when I was coming home, because of the static on the TV while I was still three houses down the street.

Gotta be nuts to run solid-core wires on the street today. Keep in mind that all the wiring in the car--including the wiring to the MSD box--acts as an antenna for the RFI/EMI.

 

[BrocLuno]

You could do the aircraft things and run woven shielding over the solids... But by the time you bought all the bits and pieces, you'd be 10X the cost of the modern premium wound wires ...
