OK, I ragged on the EC mags 16V Nology article and I also went
onto say that even tho im no journalist, I thought I could have
done a better article. So I guess its time to put up, or shut up.
(Im sure most would prefer the later.....)
The cars used for this dyno run were my 82' Scirocco 8V and Mike
Potters 87' Golf Gti 16V. Both cars are using stock VW motors.
Mikes 87 has a Gillet exhaust and a K&N filter and that's it. (He
runs in E-stock) My Scirocco has intake and exhaust mods but as
far as mechanics goes, the motor is completely stock. My engine
has about 110,000 miles on it and the head was completely rebuilt
along with the engine having been gone through a mild rebuild
about 15,000 miles ago.
Mikes car was first on the Dyno. His first run was to be with the
full Nology system on the car. We both thought that the heat
(about 90 degrees) would have some factor in the results. We
guessed maybe 2%-3% less that actual ideal conditions would result.
Humidity was about 90% so it wasn't a perfect day to do some dyno runs.
Mikes first dyno run posted a 109.2 hp to the wheels with 107.6
ft. lbs torque with the Nology system.
John (Our dyno guy) said that typically, the first runs result
better numbers because of heat factors. They usually let a car
sit for 1/2 hour or more before doing the next test just so that the
heat isn't a major factor in the results. (Usually they're changing
a component and it takes this long anyway.) We were on a somewhat
tight time schedule and didn't have the full luxury of waiting
for it to cool down fully. We removed the Nology system from his
car and installed a stock set of 16V plug wires and a set of
Bosch plugs. Then it was time for the second run.
The second run showed a gain! 111.6hp and 111.5 ft.lbs. tq. Wow,
we were somewhat shocked. If anything, we expected to see the
same numbers. W certainly didn't expect to see a gain in power from
the stock wires. Especially from the 16V. Hmm.
When Mike bought his Gti, there was a Autotech power module already
installed in the car. Mike unplugged it and since we were there, the
car was already on the dyno, we decided to plug it back in and see what
the little black box would do. We tried a couple settings. (it has
settings from 1-9.) We tried setting 2 and 7 to see what, if
any difference there was. Setting 2 showed a result of 112.7 hp
and 111.9ft.lbs. tq. Not much of a gain really, but a gain
nonetheless setting 7 showed no gain.
Well, what a major disappointment that was. We both had discussed
the Nology wires on the 16V and both agreed that of any car, the
16V would probably get the most from the system.
Now it was time for the Scirocco's Nology dyno test. We loaded it
up on the Dyno and tested the stock wires first.
The first run was a pleasant surprise for me, 95.8hp and
95.5ft.lbs. tq.! I had always figured that it had about 115hp to
the crank but these numbers say there is a little more. Cool!
Next we left the stock wires on and reconnected the coil amp
only. 96.4hp and 98.8ft.lbs. tq. Ok, the car was still a little
hot but still, we saw a .5hp gain. Surprising since we expected
none.
The last run was with the full nology system on the car. John
started the car and right away he said, " hey, it feels alot
better". Meaning the idle and he also had this funny puzzled look on
his face, as if there might actually be something there in the Nology
system after all.
The third run gave us these numbers, 94.6hp and 96.5ft.lbs. tq.
That's a 2hp loss from the completely stock system.
After 2-1/2 hours on the dyno, the verdict is in. I have to say
that both Mike and I were both Nology team players. We both
believed in the system and both expected to see almost no gain,
maybe just a tiny little bit, in the system but at the same time,
didn't expect to see a loss in power either. John told us that
with the nology systems on both cars, the throttle response was
sharper and the idle on both cars were both a little smoother.
Ok, so Mike and I both already agreed on this one so it was nice
to have a third "nonpartial" opinion confirming it for us. Numbers
don't lie. It showed a power loss on both the 8V AND the 16V. It proved
that the gospel we were preaching was wrong. Its good to be educated!
I have both Graph charts of the dyno runs scanned if anybody
wants to see them. I was going to put them up on my web page but
the files are too big. Ask and you will get!
This concluses the test.
I have also found some data that shows the iridium plugs gaining a small fraction of a percent on the dyno . Maybe using a stock coil and an iridium plug wont get a full horse but you never know. Have you also thinned the throttle plate shaft? I know its minor but we are looking for fractions here to get the 60. Is the muffler fresh packed as well?
onto say that even tho im no journalist, I thought I could have
done a better article. So I guess its time to put up, or shut up.

I say try anything. You should also whip a different exhaust on it like Mikes or Neils duals id bet would put you over the top. Cripes only the nitrous quad has broken 60 on this dyno. The 495's and 505's cant do it so it would be even sweeter to get a stock cranker to 60. I still have that bottle of liquid horsepower from the dealer show.LOL

I didn't know you were a VW freak!! Me too!
I used to live in San Diego, and visited the Nology facility just north of SD. They made a set of wires and coil amps for my 1996 Kawasaki ZX-7R... It made 113hp on the dyno with a D&D full system and Factory jet kit, plus the Nology setup. The dyno operator/racer (Jeremy Toye of Lee's Cycle) said it was the smoothest hp curve he had ever seen, and attributed that to the Nology setup.
The setup was expensive, about $250 total. The reason I went for them was because I initially tried an Accel universal setup that was terrible to install, so I limped it to Lee's on 3 cylinders and got the Nology setup done (among other things).
Nology may be on to something, but I never witnessed any hp gains with their system. The additional capacitors in their spark plug wires really make no real electronic sense, but hey, I guess they are making money.....
