Hi all,
have someone this cool Thinks from Nology in the Shark?
I see this on 928 Specialists Page, but i want known some from you. Itīs easy to install, or/and are this good Components?
Please give an easy anwser, cause iīm from Germany and my English is bad, like my Shark fast ;o)

Ricco,

A friend of mine recently installed these on his '84 Euro. He is very happy with them and installing them was not too hard. He says the car feels more responsive when accelerating.

Probably needed wires anyway. I have heard that the Hype of Nology is exactly that (HYPE) just my .02 cents.

I've heard exactly the same thing from a number of people. Yes, the Nology wires will make your car run better IF the old wires were bad. Of course so would an old coat hanger in that situation.

I do like the plug end boots that are used on the Nology wires though. Anyone know where these would be available from separately? I already talked to Nology, and all they wanted to do was sell me a whole set of wires for over $400.

Ricco,
There was a post earlier in the year on the Nology hot wires -it should be in the archives- the gist of the post was that while it was a good wire the cost was high and for some reason the plug 'BOOTs' would occasionally pop off. I have no experience with the Nology's one way or the other but in their defense I can't imagine plug boots just popping off IMO I'd say they weren't secure in the first place.

If plug boots are put on with enough air trapped in them they can pop off. The seal created between the bottom part of the boot and the porcelin of the plug keeps the ain in and the boot on. With the engine running the trapped air warms up, and the pressure can increase to the point that it's enough to overcome the seal and blow the boot off like a cork coming out of a champaign bottle.

FWIW,

I have seen a couple of articles in car mags where they showed some minor dyno improvement in side-by-side testing with other aftermarket & oem wires. I believe you can link the articles from the Nology web site.

If your plug wires are bad, then pretty much any set of new wires is going to help. A lot.
And the Nology wires certainly dress up the appearance of the motor.(IMHO)

That having been said, from an electrical perspective, they don't make a lot of sense with a modern (well maintained, fully functional) electronic ignition. And you don't see them, or any parallel in use by many racers, or any OEM - which begs the obvious question, why?

This does NOT mean that they don't work, just that there does not seem to be a body of evidence to support the claims. As always, YMMV.

Just my .02

Mike,
I can visualize what you are saying and I won't dispute the possibility, but, that would need some seal!!!

Mike--

In my limited experience, plug boot seals are never this good. I use dielectric grease to improve the seal and protect from any possible moisture ingetsion, and it's never to the point where it would be that good.


Just to add a little science to the discussion, think about the amount of "pull" you use to remove a plug wire, in pounds. Think about the area of the cross-section of the plug where the wire boot attaches. That area is less than a tenth of a square inch. The pressure --increase-- in that little cavity (in PSI) would have to be over ten times the "pull" number you remember from above before the boot would release. Consider also that the volume of the boot with the plug installed is pretty small, so as the boot moves slightly the internal pressure drops quickly. So, is there --any-- movement when the boot gets hot? Probably the tiniest bit, but really too small to measure. More likely is that as soon as the boot moves at all, the built-up pressure releases and the movement stops.


Cheers!

That information was from stuff I've read in the past from some plug wire manufacturers. It won't occur if the silicone grease is put in the boots. The grease will seal out moisture, but also prevent the boot from sticking to the porcelin of the plug. That's supposedly when this is more likely to happen. The metal terminal not being tightly on the plug's connector increases the likelyhood if it coming off that way too. Some of this installation procedures I've seen from plug wire manufacturers says to use the silicone grease in the boots to seal out moisture, minimixe the volume of air trapped in the boot, and to prevent the boot from sticking to the porcelin. I've also seen where burping out the air as much as possible when installing the boots was stated.
