I ran across a dyno test of the Nology wires that you may be interested in.
It was published in Muscle Mustangs and Fast Fords. The test was performed
on a Dynojet rear wheel dyno using a 5.0 powered late model Mustang. The
engine had the usual go fast parts (long tube headers, aftermarket cam, etc.)
and the baseline ignition system was:
Autolite #25 plugs, 0.048 inch gap, SVO Motorsport wires, MSD
Blaster II coil, MSD 6AL ignition box, 38 degrees timing
No mention was made of trying to optimize the fuel pressure or timing for the
baseline.
For the Nology pulls, the ignition system was changed to:
BERU Silverstone plugs 0.035 inch gap, Nology HotWires, Nolog ProCoil
for MSD style ignitions, MSD ignition box, 33 degrees timing
The first Nology pull was made with 38 degrees timing and lost 15 horsepower
compared to the baseline. The article claims this is common and that the
Nology system works best with less total timing. After several dyno pulls
to optimize fuel pressure, spark gap, and total timing, the Nology system
made 3 peak hp more. It also averaged 4 hp more from 4700 to 5900 rpm.
The article indicates the power was made by leaning out the fuel mixture.
I consider this a tainted test since the baseline was not similarly optimized.
However it does show that, at best, the Nology parts make only a marginal
improvement.
