Nology wires... Using them w/ Multispark type Ignitions?

[brads at mindspring.com (Brad Sheridan)]

 TBerk, 

  Nology wires with a multispark ignition are basically redundant, and
don't give any pluses. Here are a couple of things to consider:

1) With a stock style ignition, the rise time when the coil is fired is
fairly quick. Adding a capacitor like Nology does, slows this rise time
down, because you have to charge the cap in the wire. The result will be
that the timing is retarded slightly by a set time, and this time will be
most noticeable at higher RPMs, on the order of a degree or two. The small
amount of energy stored in this cap is released at the very nanosecond of
the start of the spark. After this very brief bump, it goes back to a
standard discharge for the majority of the spark. This nets you a slight
timing delay, and a questionable difference in initial spark current. This
isn't just theory either, I have seen it with a good oscilloscope, and high
voltage probe.

2) A Multi Spark ignition(I think what you are talking about is Capacitive
Discharge) generally has an even faster rise time, and should not be
affected as much by the capacitor in the wire. BUT, the cap is also a moot
point. The CDI ignition delivers a hotter shorter duration spark already,
with higher current. The wires won't make nearly the difference in spark
that the ignition will. 

The reason I pointed out you are talking about a Capacitive Discharge
ignition, instead of Multi Spark, is that Multi Spark is more hype than any
sort of real performance benefit. For starters, most capacitive discharge
ignitions that multispark, spark once a millisecond, and only up to around
3000rpm or so. So if you do the math, at 3000rpm, that second spark occurs
20 degrees retarded after the first. Is a spark that retarded going to give
you optimal performance? Now if you compare that behaviour to a standard
ignition, the standard ignition has a much longer spark. And if the spark
is blown out for whatever reason, as long as enough energy is stored in the
coil, it will restrike again immediately, instead of the timed delay of the
CDI. CDI Multi spark is good for emmissions, and a smooth idle, more than
it is for power. 

  Anyhow, to sum it up, any good quality wire will work just fine.
