Torque-d to the Tit-s
Photos and Words by Michael Kent

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.

“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.

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...

 

Question of the Month

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

Viewer’s Rides

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.
