Does anybody know if magnecor 10mm race wires come in any other coloir than red? It's just a thought.

No, all Magnecore's are red. They also have a ver snug boot fit and i've had two boots split. My Vitek wires have excellent boots. I just don't like the uneven wire length.

Only red. I have 'em.

Hi

I saw the specifications of the RX7 of "getaway in stockolm", it marked there :

"Magnecore 8,5mm and 10 mm ignition cables"

why to have used two sizes of plug wires ?

Magnecor R100 plug wire (10mm) is it a good choice for origin car or 8,5mm is enough ?


Thanks

David Beale

The 10 mm will not fit in the stock wire clips. They are for those who supply their own clips and do their own (different) routing - such as race cars.

The 8.5 mm do fit the stock clips and are intended as a stock replacement.

Be aware, you have to "burp" the boots when you install them - this means letting the air trapped inside the boot escape. I use a paperclip inserted beside the plug insulator - you pull the paperclip out after the boot has seated. The boots are a very good tight fit. I also put silicone grease on the inside of the boot so it doesn't stick permenantly to the spark plug.

Thank you for information

Does that want to say that all those which bought Magnecor 10mm modified their cable?

David Beale

No, some just install them in the stock positions, but they do have to find some other way to hold them (zip ties, new holder, whatever). The 10mm don't perform better unless you have a "super duper" aftermarket ignition system. Then they become more important, as the stock size wires can let the spark jump through the insulation. Usually, spark leakage occurs around the spark plug boot - you can see it jumping from the boot to the spark plug metal hex. That is why the Magnicor wires have such a tight boot - to try to stop that leakage.

Ok, I will buy the magnecor 8,5mm finally

Taylor are cheaper and better due to lower resitance.

I saw a test with all the wires and I believe the Accels beat them all and Taylors were a distant second. I'll find out.

David Beale

Lowest resistance is best if you're racing only, Chuck. Ignition wires are a compromise. Do you want to drive and listen to the radio too? If so, you need noise supression. Magnecor give supression at the lowest loss, as they use a ferrite core, so they use less resistance per foot at any given noise supression rate. I like the tight fitting boots of the Magnecors as well. I've built my own sets of Accel wires (buy the inexpensive V8 sets, and make two RX-7 sets out of them). They worked fine as well. I haven't found Taylors around here so don't have experience with them.

Personally, I haven't seen any difference in operation from one wire set to the next - when they're new and in good condition.

Of course many RX-7s are loud enough inside from the exhaust that it's a moot point. You might as well have "racing wires" (stranded copper core), as there is no way you can hear the radio on the highway anyway.

how often should the spark plug wires be replaced? i bought some racing beat ones about 3 years ago. maybe i should get some new ones?

David Beale

If the ends are loose yes. If the wire insulation got burned or abraded say 1/16" or more yes. By ends loose I mean when you pull the end out of the coil is the metal bit firmly attatched to the wire insulation and is the centre conductor attatched to the metal bit? Ditto for the plug ends.

Otherwise they last a long time. Mine are 7 years old, I think. Still going strong. You can check them with an ohm-meter as per the shop manual, if they are stock or NGK. Other makes should be at those resistance values or lower and shouldn't vary much if you move them around while testing. If they ever get an intermittant open they will burn up quickly from sparking. Sparks are for spark plugs!

I put the question concerning the magnecor R100 with various tradesmen
one answered me :

I have not heard that before and I have sold a lot of those wires. Most
people go with the 10mm wires.

if this model is not compatible, why don't they have not return?

?!?

Don't worry about all this wiring clip mumbo jumbo.. the 10mm wires are all exact length of stock wires, you route them around and through the exact areas you pull your stock wires from, and you don't need any special clip to hold them in place.
