ed’s letter

There are quite a few people out there who would question the wisdom of most 4x4 adventures. They are sure to ask what motivates the desire to travel for days on bumpy gravel roads and, after hours of inhaling dust, to set up a flimsy tent on a windswept open area rampant with wild animals – then scrabble around in the back of the vehicle for food and sleeping goods, while making a fire to cook on. What’s wrong, they tend to say, with manicured tarred roads, hotels with comfortable beds, and kitchens staffed by competent chefs? We head out, I reckon, to reclaim a sense of adventure, to check out new places, and find some calm in the bush that you can’t in town traffic. A 4x4 journey is a way…

forum

LIVE WITH THE FUNNIES As an avid reader of SA4x4, I sometimes wonder at how nit-picky some people can be. I refer to the article in the Forum of the February edition, titled “Bakkie Oversights” on page 6. One sometimes has mishaps that you cannot avoid. For argument’s sake, someone will have endless problems with a specific vehicle and the next owner will drive it till the wheels literally fall off and never have an issue. Anthony Stokes complains about vehicle wiring. I’ve had my share of funnies in vehicles as well. My wife drives a 2009 Audi A3 Cabriolet, which had a fault come up that indicated a globe was not working. Checking all the fuses showed nothing amiss. I found a reverse light was not working, but even swapping globes between…

overlander’s code

In response to a growing number of complaints about how we conduct ourselves in the wilderness, we decided to draw up and promote a code of conduct for overlanders. We’d like to include your input, comments and debate, so please send your suggestions to editor@sa4x4.co.za. FIREWOOD Take your firewood in with you; don’t chop down trees or gather dead wood within parks or wilderness areas. KEEP QUIET We go to the bush to appreciate the sights and sounds of the bush. No music, and nothing louder than a spoken conversation. RESPECT LOCALS – LAWS AND PEOPLE Obey the rules of the place you’re travelling through. Respect locals and their traditions; if they don’t like having their photos taken, don’t take photos. SUPPORT LOCAL TRADE Your spending money at the local shops and lodges will…

part 6: shackles

In today’s day and age, with access to all the information we have ever wanted at the click of a button, it is scary to see how uninformed people really are. As a result of this, we often hear about how things go horribly wrong when it comes to recoveries. Which brings us to shackles. These are a key element in the recovery bag, and there are a few types available. For our purposes, they are typically a piece of cast metal or strong nylon rope used to attach a recovery strap to a point on the vehicle. As with the straps, there is always a right and wrong application. Shackle types D-shackle: These are NOT to be used for any form of recovery. D shackles are only used for lifting applications and are…

downsizing and why it’s the future

We all love the sound of an old Rover V8 or the scream of a four-litre Lexus-powered Cruiser blasting up a dune. These large capacity eight-cylinder drinkers sure are good to hear and even better to drive – if you’re not paying the fuel bill. Nowadays, modern petrol engines have lost much of their aural tone and character, but despite being half the size they make the same power as V8s of 20 years ago. The case for diesel engines is the same, with downsizing taking effect and cylinder counts dropping. To keep power up but fuel consumption down manufacturers are using turbos. It’s an established trend, we know this, but why has this proved to be the engineering solution? The simple answer is thermal efficiency; the percentage of energy converted from…

what is a turbo?

A turbo is what you get when you connect two fans on the same shaft. One fan is driven by the exhaust gasses being expelled by the engine, while the other fan compresses gasses going into the engine, force-feeding the engine more air. The energy that would otherwise have been wasted out of the exhaust can, therefore, be recycled to boost power. The more exhaust flow there is, the more boost a turbo can produce and the more power the engine will make, which is why turbocharged engines make very little power at low rpm where there is insufficient exhaust flow.…
