How To Get Into Go Karting

Saturday, July 9th, 2011

If you would like to get into some form of motor sport, but are absolutely appalled by the costs involved, maybe you have overlooked Go Kart Racing. All right, nothing is cheap anymore, but go karting is comparatively cheap in comparison with its far dearer cousins like Formula One, Formula Drifting, NASCAR and Cross Country Rallying. You can get into go kart racing as a spectator, as an investor in a team or as a member of an active team as a mechanic or driver.

Or you could use go kart racing as a spring board into the more expensive forms of motor sport. You can learn a great deal about driving, designing and constructing cars by starting with go karts. After all, the principals are in essence the same, but the components in karts are a great deal cheaper.

In the rest of this piece, we will take a look at some of the components and safety aspects of go karts along with approximate typical prices.

The first thing you will need to investigate is the sort of kart you want. There are different levels as there are in other motor sports. as a beginner, you actually should start with the low powered karts, because you will have to learn a great deal of new driving skills and quite a few safety regulations before you move on to more highly-rated karts.

If you find the price of a new kart a bit high or if you would like to leap-frog over the lower levels of karting as quickly as you can, you could think about buying a second hand kart for the first few levels, only buying a new one once you get to the level of karting that you would like to be at. However, do not make the error of attempting to run before you can walk.

Entry level go karts are not costly. For instance, at the time of writing, a battery operated go kart costs about $300-$400+ while a petrol powered kart will cost $600-$700+

Although go karts have a very low centre of gravity so do not tip over easily, it can happen and crashes do occur so wearing the correct safety clothing is vital. Again, you could purchase a second hand set of racing safety clothes, which are in essence the same as for motorbiking, if you just want to get going on the cheap.

You will require a jacket and trousers or a one-piece jump suit; a helmet, gloves, a neck-collar and boots. This little lot could set you back anywhere between $300 and $400, but it will save broken bones or worse, especially in the period a couple of months after you begin when you think that you know it all. Accidents occur once individuals become over confident.

You will also need a few common spare parts, a spare tyre, fuel and oil, say $250 and you are ready to take your first lessons in your own go kart. Or maybe you would rather learn in someone else’s kart first? This is not a bad thought, because it will give you some experience with different forms of karts, which will help you choose which one you want (or can afford).

Some Design Features Of Formula One Cars

Friday, July 8th, 2011

There is no question that Formula One racing is a gripping motor sport for those interested in cars, speed, engineering and design. The design of these Formula One cars is crucial to the speed that the car will travel at, and it is also imperative for the safety of the driver.

For this latter reason, there are strict design rules applying to all cars in this motor sport and any car that does not abide by the rules is disqualified from taking part in the races. It is rare for car designers to infringe these rules because the cost of driving in a race and the benefits from doing well are massive.

Having said that, Formula One car racing teams push the design features of their cars up to the limit. The key to gaining maximum speed with maximum fuel efficiency is having as aerodynamic a design as possible. These cars are as well designed as any fighter jet, but the foremost difference is that fighter jets are intended to leave the ground whereas cars are not.

Therefore, another vital part of the design is creating down force to keep the tyres firmly on the ground. It is important for a number of reasons for the tyres to have a decent grip on the track. Without this grip or traction, the car cannot accelerate, but without it they cannot stop either. Therefore down force and tyres are a major factor in speed and safety.

The brakes are extraordinary as well as you can imagine. They are basically the same as those used in stock road cars, yet the components are rather extraordinary. because they have to work and remain working at high speeds, this means that they develop high temperatures.

Ordinary metal would buckle or even melt, so high quality carbon fibre composite disk brakes are utilized instead in conjunction with brake pads of special composites which are often extremely secret. There are a great deal of jealously guarded secrets in the designs of contemporary Formula One racing cars.

The main part of a racing car is the monocoque, which is the section that holds the engine and the driver. The car’s suspension is also mounted on the monocoque so it is clear that it has to be very strong. This strength is normally gained by constructing it from carbon fibre.There are also numerous safety features built into the monocoque for the benefit of the driver.

The engine has to be light-weight, efficient but powerful, which is a very tall order indeed. There is now also an FIA regulation that the engine has to last for more than one race weekend. Engine failure is the main cause of pulling out of a Formula One race early. The gearbox suffers equally in a fast race. Another regulation states that all gearboxes have to be manual – no automatic gearboxes. This adds to the wear and tear.

The suspension is manually adaptable so that it can be fine-tuned to each race track and the conditions prevailing on a race track at any given time. The suspension is not there for the comfort of the driver but to raise the likelihood of the car winning.

Porsche 977

Sunday, December 20th, 2009

A new Porsche 911 is always intriguing because it’s exciting to see how after more than 40 years of improvement the Porsche team still manages to bring changes and advancements to this iconic model.

The new 997 combines the silky contemporary appearance of the 996 series with the popular retro styling of the older 911′s. The front end is completed with round lights and separate parking/fog/indicator lights. This modification, combined with wider hips resembles the last of the air-cooled 911′s, the 993. Other changes in the body shell are the new door handles, wing mirrors and the trendy cut of the rear wings into the bumper/lights.

Even if the 997 looks a lot like the preceding model, the 996, the new car is in point of fact 38mm wider which makes for a more forceful look. With each new model brought out, Porsche has tried to reduce the drag co-efficient helping the 911 glide through the air more efficiently thereby aiding performance. The same thing has been done with the new car, and if we compare the 993 Cd of 0.34 to the 997`s 0.28, we can see how far the aerodynamic game has moved on. The latest body shell and rear wing combine with new under body paneling to also offer increased levels of down force for this latest evolution of Porsche’s best.

The latest Porsche model has the best handling 911 ever. Improving a car’s rigidity helps ensure that the suspension can work more effectively and although not making such a quantum leap as the team did with the 996, Porsche improved torsional rigidity by 8% and added as much as 40% more strength.

For their new model car, Porsche wanted to improve crash safety provisions so they added two new air bags, which are situated in the side of each front seat back-rest and are designed to protect the thorax. They also kept the earlier two front and two side airbags, which means that now there are six air bags in total. For the same reason, that is crash safety, the reinforced body shell boasts further protection such as a more extensive use of super high strength steel.

The most recent model is also 50 kg heavier than the 996. The reason is that modern crash safety regulations sort of force vehicle makers to produce new cars of increased weight, despite the prevalent use of a large range of weight saving measures, such as an aluminum bonnet.

Aside from the crash safety advancements, much of the additional weight can be attributed to the higher standard specifications of the new cars. The power to weight ratio is analogous with the latest car offering 233 bhp per tonne against it’s predecessors 238 but the new model’s superior aerodynamics must help it achieve Porsche’s claimed performance figures, which are identical to those of the 996.
