Christmas with my parents was a whole lot of the
usual. For the past 8 years, my Christmas wish has
been pretty consistent; “Please Santa, let
Mom and Dad win the lottery and buy me a Skyline
this year… Better yet, let me win the lottery
so I can buy my own Skyline… Or… why
don’t you just give me a Skyline?” Knowing
that Santa probably has no idea what a Skyline is,
I’ve left numerous 1/16th scale models around
the tree and near the chimney, but this has all
gone to no avail. Fine, I’ll settle for the
Drift Silvia I’m building…
So Skyline-less, I drove to the shop where my pieced
together 180sx slouches, begging to be completed.
I started by tightening everything down to torque
specs (based on an S13 Service Manual). When Pat
and Candido arrived, they started laughing at me,
brought out the air gun, and started tightening.
Pat looked at me and said, “Torque Specs?
Tighten it until it breaks, and then go half a turn
back.” Patronizing bastards. So what’s
the real deal, then? I was under the assumption
that having the car at the correct torque specs
was a necessity, especially when a car is pushed
to its limit. As the car handles, the design of
the threads and pitch will seemingly tighten, and
in no doubt, stay tight as the OEM has designed
them to. However, if they are too tight from the
get go, they may break or misshape the attached/bracketing
metal. So what do we do for drifting?
The last freaking thing I want is to be at the
Formula D and have one of my Crossmembers come loose,
but at the same time, I don’t want to ruin
all of the new racing parts I’m installing.
So I made a couple of calls, and everyone told me
pretty much the same thing: “Call me again
on Christmas morning, $*&hole and we’ll
pull your sponsorship.” So I stopped at the
two people who didn’t tell me to bugger off.
Paul St.Clair, Motorsports Planner,

“When working on a do-it-yourself project
car, the OEM torque specs should be used as a rough
guide. It is wise to consider what you are changing
in the system and determine the correct torque for
each particular nut and bolt. Typically, aftermarket
parts come with hardware that should be better than
the parts you are removing. For example, you would
use at least Grade 8 bolts in a shear application
or when switching to spherical bearings from rubber
bushings. When the load demands change drastically,
the bolt torque should be adjusted accordingly.
At this level, one should consult Carroll Smith's
"Nuts, Bolts, and Fasteners.” Basically,
your torque spec depends on the metallurgy of the
parts you interfacing, the function of the parts
and size and grade of the fasteners.”
Erik Jacobs, President, www.dgtrials.com,
Formula D competitor (Team Toyo)
“Drifting is a sport where you bonk things
a lot. Suspension components are put under tremendous
side, axial, radial, and other loads that otherwise
would not exist. The designers of the individual
suspension parts most likely did not anticipate
these loads either. Unless you are assembling the
car under perfect machine shop conditions, temperatures,
humidity’s, etc, just crank the s$#t out of
everything. The last thing you want is to bonk something
and then have an arm fall off or break because it
was just barely under torque-spec. A factor that
may affect this incorrect reading can be as simple
as a torque wrench being as little as 10% inaccurate
at that setting. Nearly every nut and bolt on my
drift cars are tightened to the max and they STILL
come loose on a regular basis. Drifting is just
that hard on a car.”
So they’re you have it. Based on my experience,
suspension components on any car are not too sensitive.
It’s not like torqueing down head bolts where
you need to be exact and precise. With the extremely
limited time I’ve had on the track, my expectations
may be incorrect, but I wouldn’t be surprised
if, like Erik said, everything will come loose even
when torqued to the max. Once you go through the
process of finding all of the nuts and bolts you’ve
removed (something I ended up not being too good
at…) be sure to use this advice from the experts.
Or don’t. It makes no difference to me. Frankly,
I’d prefer you to ignore this entire article,
so it’ll be your Crossmember falling out at
the Formula D instead of mine. |

Featured
Product: PathfinderTM Lubricants
Normally for this newsletter, we stay away from
featuring any products. It’s hard to imagine
how a particular exhaust system sounds on a Viper,
so we’d much rather bring that exhaust to
life on the show, where you can see and hear what
it’s like. But the PathfinderTM Lubricants
definitely need addressing. Apparently only one
ounce of their Oil Fortifier will treat up to 5
liters of oil. Matched with an actual horsepower
gain, as seen on last year’s Sports Car Revolution,
this stuff needs a recap.
Currently, PathfinderTM Lubricants offer two products;
an Oil Fortifier and a Fuel Treatment. The Oil Fortifier
increases the film strength of oils, resulting in
less friction and wear on engine components. This
efficiency boost means a slight increase in horsepower,
compression and fuel economy. This fortifier will
withstand frictional contact up to 200,000psi as
well as maintain cleaner oil between drain intervals.
The Fuel Treatment acts as a lubricant to both diesel
and gasoline fuel systems. With this lubricant,
the fuel pump, lines, injectors and even top end
cylinder rings are lubricated with a fireside furnishing
lubricant present in the additive. This promotes
a cleaner combustion cycle, improves compression,
raises horsepower and fuel economy, and also reduces
engine oil soot deposits. Clearly, using both of
these Lubricants is a necessity to any engine.
Here is a report from the Mississauga Transit
System after using the PathfinderTM Lubricant products
on their buses:
Mississauga Transit System
Mississauga, Ontario
The following tests were conducted on three Mississauga
Transit buses with Detroit Diesel 50 Series engines.
The buses first ran 9000km without PathfinderTM
Oil Fortifier and Fuel Treatment. Then they ran
the buses for 9000KM with PathfinderTM products.
The benefits of using PathfinderTM were as follows:
Oil Analysis conducted by: Agat Laboratories
Engine Metal Wear
- There was a 50% drop in engine metal wear when
using PathfinderTM Lubricants, representing 2 times
more engine life, as well as reducing maintenance
cost, engine re-builds, capital expenditures and
down time costs.
Soot in Motor Oil (ABS/DM-1)
- Soot contamination in motor oil was reduced by
76% with PathfinderTM Lubricants.
Fuel Economy
- Fuel economy improved by 5.04% with PathfinderTM
Lubricants.
Emissions
- Using PathfinderTM Lubricants, a reduction of
24% was recorded on tail pipe emissions via an opacity
meter. This reading exceeds the 20% reduction goal
of the Kyoto Accord.

1996 GMC Rally 329,400km
1997 GMC Safari 219,800km
1994 Astro Van 194,800km
2000 GM 3500 Diesel 226,400km
1998 Ford Windstar 197,800km
Analysis and Results from using PathfinderTM
Lubricants:
- Our oil analysis results show a 4 to 1 drop in
engine wear, which represents a longer engine life
of 3 to 4 times over
- We have never had to re-build or replace a motor
in our fleet
- We have never failed an Emissions test
- Fuel economy has improved by 15-20% across the
board
Over the years, we have greatly improved our bottom
line by savings in equipment replacement, downtime,
maintenance, fuel cost and by consistently passing
Emissions/Drive Clean tests.

What
does Toureg mean, anyways?
Story
by: Tom Hnatiw
Photos by: Jeff Lorriman
Approaching this vehicle for the first time,
the burning question in my mind had to do
with motivation. Why did VW choose to build
this car and where does it fit in the lexicon
of VW vehicles? Within fifteen minutes of
climbing behind the wheel I no longer cared
about the answer. I only know that this car/truck/SUV
is so damn good, it deserves to be taken very
seriously.
On a five hour trip to Mid Ohio, I found
a seating position which I could use for a
twelve hour stretch, if need be. With more
head room than others in its class and a seriously
rugged seat cushion, the VW has obviously
been well thought out. The instruments are
exactly what you would expect from VW –
no bull, just what you need and in a layout
that shows clear research and development.
I have never cared much about HVAC so long
as it works. Since sound doesn’t really
concern me, I usually care less about center
consoles. But the center stack in this car
is well done, sensible and easy to use. Good
for you, VW.
I did have a problem however. Without cruise
control, I could not stop the Toureg from
topping 100 miles per hour. In top gear, the
speed simply creeps up to the point where
you think that everyone else on the road is
towing a piano without a trailer and then
you glance down and, “Oh GEEZ!”…
Pulling into the paddock at Mid Ohio I realized
(to the point of annoyance) the curb appeal
the Toureg had. Every third or fourth pedestrian
would wave frantically and run over to ask
the three questions:
“How do you like this thing?”,
“Is it as fast as they say it is?”,
and “How does it compare to the Cayenne?”
The last question is one I won’t touch
with a ten foot pole. If there is an identity
crisis here I’ll let smarter car guys
than me sort it out. The answers to the first
two questions are always, “I like it
a LOT,” and “Oh yeah, it’s
fast.”
After a days work I was not surprised to
find the thing covered in dusty finger prints
with the odd nose print on the glass. People
are definitely interested in this car.
In Monterey, during the most expensive cruise
of the weekend (and perhaps in the world),
VW organized a hill climb event for all of
the press and well heeled car guys near a
golf course. The language used on the invitation
escapes me but roughly translated it meant,
“Come and beat the hell out of a Toureg
and see what you think.”
The course was a combination of elevation
changes, short, sharp straights and tight,
bumpy curves, but hitting a tree was still
near impossible.
Now most so-called SUVs have the intention
of looking mean on the streets but acting
weak off the roads. Blatantly speaking, the
Toureg ate this place up.
Never losing poise, the Toureg gently reminded
me that it was much better in this environment
than I was. I have no idea where the limit
was, but I was certainly not prepared to stick
my neck out far enough to find it.
In the paddock area was a Volkswagen engineer
who was available to answer any questions
the participants may have had. After an hour
of completely engaging conversation with the
chap, I marveled at how much technology was
packed into this car.
You may treat the Toureg like a grocery getter,
and be serenely happy with it. But if you’re
a techno geek like some of our staffers, there
is enough tech to keep you entertained for
months, if not years.
Recently I was given a press model Toureg
to refresh all of these fond memories so I
could sit down and write this piece. A year
or so after its launch, the bloom is far from
off the rose. The curb appeal has not decreased
at all. This particular press car with a years
worth of journalists (most of whom couldn’t
drive a finger into a body orifice), beating
on it was every bit as tight, every bit as
rigid and every bit as good as the first example
I drove.
On my Cottage road, most often deserted and
very well known to me and my two sons, the
Toureg ate up the road with aplomb and in
one or two sections, hit mind boggling speeds.
The brakes put seriously to the test, never
showing a bit of fade while easily modulating
to the edge of its ABS.
Most vehicles this size do not like the moment
of turn in very much. The Toureg doesn’t
mind how you do it, whether you yank on it
or sensitively point it towards the apex.
It follows instructions and with a tolerable
amount of body roll, gets to the middle of
the turn without drama.
After two headlong rushes up and down the
road, it was too easy to forget that I was
driving a large SUV. It felt very much like
a sports car – so much so that I began
to make plans to take the Toureg to the Sports
Car Revolution test track. But that would
be silly, wouldn’t it?
I decided to try that idea out at a later
day after an examination of its rollers. After
a full year of testing by Neanderthals like
us, the only thing that was untoward about
the Toureg was the tortured Pirelli tires.
I didn’t want to be the one to finish
off these expensive tires as a prolonged track
session surely would.
With a heavy sigh I returned the Toureg to
the pool wishing that I could have spent more
time with it. We’ve since booked the
V10 Diesel example for a long test later on
this season. With over 500 foot pounds of
torque I can only wonder how much fun this
one will be...

| What
is the difference between turbochargers and
superchargers and which one is better for
horsepower and the car itself?
-Blair, off of the Internet
 |
Answer:
A relatively simple answer,
but a long one, no doubt. Since we’re
limited for words, here is the briefest explanation.
Turbo and Superchargers work off of a Forced
Induction operating system, where more compressed
air is shoved into the engine, thus speeding
up the four cycles a piston goes through;
therefore making more horsepower.
Whichever method you choose could be damaging
to your car if, a) you do not have the proper
supporting hardware (larger injectors, properly
mapped ECU, etc) and/or b), if your engine
was not intended to receive a blow job (I
love being the editor and the writer…).
Engines that are factory turbo or Supercharged
save a lot of the trial and error work required
on making your motor perform so well. For
instance, piston cooling oil squirters are
not a necessity, but they help keep a force
fed motor operating at its peak. Running oil
and cooling lines to either a Turbo or Supercharger
requires tapping the block or tee-ing into
existing hard lines; something not everyone
feels comfortable with.
A Turbo charger feeds off of exhaust gases,
with the unit itself attached to the exhaust
manifold. These hot gases spin a turbine fan
blade, which in turn spins a compressor wheel
that mixes atmospheric air with the exhaust
mix, and shoots this compressed mixture of
air back into the intake manifold. Usually
running through an intercooler, which helps
to keep the compressed air cool and in reserve,
a Turbo charged motor is capable of producing
upwards of 1500 horsepower in a drag application.
Downsides involve turbo lag- the time it takes
for the turbine to build the required boost
and shoot it through the compressor housing,
and a massive amount of heat- both externally
and internally.
A Supercharger works off of a belt-pulley
system, connected directly to the intake manifold.
A belt that feeds off of the existing crank
pulley/harmonic balancer creates boosted and
compressed air that needs no spooling time,
thus making a broader torque curve on a dyno,
with power constantly on tap. Superchargers
are also known for making some crazy power
on the strip, however in a street application,
I’d personally go with a turbo charger.
It sounds cooler, looks neater, and allows
for a wider range of aftermarket possibilities
without breaking the bank

I bought the car in 2003 with 15,000
kilometers. The car still retains a
Ford premium care warranty with $0 deductible
warranty until May 2008, so it was a
perfect car for me to mess around with.
As every Mustang aficionado should do,
I started researching the history of
the ‘Stang. Total production was
5,582 in Dark Highland Green; of which
3,041 were this limited production Green
(that Ford will not produce again),
1,818 were Black and 723 were True Blue.
Ford decided to produce the Bullitt
after they received an overwhelmingly
positive response from consumers who
saw a concept version of the car at
the 2000 Los Angles Auto Show. The Bullitt
was designed by Jay Mays and was produced
at the Dearborn Plant in Detroit, MI.
The Bullitt option was available for
$5,695 Canadian ($3,695 US) on top of
the base price GT with only one option
available; a Mach 460 6 disc in-dash
CD player. Steve McQueen's heirs worked
closely with Ford on the project to
honor the legend himself. What you received
for the Bullitt option was as follows;
1 – A 4.6 liter engine with 275
hp which was 10 hp above the GT, a unique
twin 57mm bore throttle body, cast aluminum
intake manifold, high flow mufflers
and optimized alternator and pump pulley
ratios
2 – A unique sounding free flowing
exhaust with rolled tips
3 – A Performance Handling package
that included new spring rates (3/4
inch lower than GT), revalved Tokico
shocks and struts, unique stabilizer
bars front and rear, beefed up frame
rail connectors
4 – A Performance Brake package
that featured custom 13 inch Brembo
brake calipers powdered coated red with
an interpolated mustang horse
5 – The exterior of the Bullitt
was also heavily modified with unique
C-pillar and glass, unique side scoops,
unique rocker moldings, a brushed aluminum
fuel filler door, and Bullitt badging
6 – The interior featured a unique
heritage instrument cluster, a unique
brushed aluminum appearance accents,
pedal covers, shift ball with shift
ring, door lock covers, custom sills
with molded-in-Bullitt nomenclature,
and uniquely styled seats
7 – Serialized Special Edition
identification plates to ensure exclusivity
and authenticity
8 – Under hood clear coat paint
It is pretty clear how much I love
this car. It will be my baby for some
time to come.
