Performance-Enhancing Modifications

February 5th, 2015 Comments off

If you are a fan of white-knuckle rides and fast-paced cars, you are likely searching for some performance enhancers which will provide you with a bit of extra kick. Although some of these can be quite technical in their nature, it is still a great idea to have a quick look at three of the most common additions that are used.

Nitrous Oxide

Nitrous oxide works by increasing the combustive capability of your engine. In other words, a greater efficiency is achieved. This is one of the reasons why nitrous is often used during straight races (such as those on streets). Tanks can be kept in the back seat, the boot or even in the glove compartment.

Spoilers

These visual additions do much more than add a bit of class to your car. The main point of a spoiler is to force the back of the vehicle down when air flows over the top. In turn, this provides much greater traction. The only other way to accomplish this would be to increase the weight of the car; not ideal if you feel the need for speed!

Cold Air Intakes

One of the issues encountered with many high-performance sports cars is that their engines tend to overheat rapidly when driving fast. Often, coolant alone is not sufficient. In this case, many enthusiasts will add a cold air intake atop their bonnet. This attaches directly to the engine. The end result will be a natural flow of air into the hottest parts. So, oil will stay cooler and higher speeds can be achieved without worrying about damaging sensitive parts (or the engine itself seizing up).

So, it is clear that such enhancements serve very functional purposes within any vehicle. Ranging from a few hundred to a few thousand pounds, these devices will certainly provide you with the “kick” that you need to enjoy a fast ride!

Modifications for Racing

October 27th, 2014 Comments off

Many car owners have often wondered how their vehicle would perform on the track. The performance of the vehicle may be more than adequate on the public road, but racing on the track puts additional requirements on a car in order to make it competitive.

Many owners believe that the route to speed involves more brute engine power, and once the car is sufficiently powerful it will win. However, whilst power is an important factor in racing, it is just one facet of design that makes a successful racing car. 

A high top speed can be redundant on many tracks, as twisty circuits with many turns make high speeds impossible. It is important that the car’s power is useable, and the entire vehicle package is designed for high average speeds over each lap. 

Reducing weight is an important factor in making a car useable on the track. A high power-to-weight ratio will increase acceleration out of turns, as well as improving the ability of the vehicle to change direction.

For this reason, superfluous items such as excess seats, panels and instruments are removed to pare the car down to a minimum weight. All engine and chassis parts are designed to be as light as possible, and lightened engine internals are fitted to reduce the engine’s internal inertia. Road cars are fitted with suspension that is geared towards a comfortable ride, whilst race cars have stiffer shock absorbers to make the car stable at speed and improve the engine’s ability to get power onto the track. 

Uprated brakes enable the driver to be able to tame the power and brake for optimum corner speeds, and race cars feature treadless ‘slick’ tyres that become sticky when hot to maximise traction. 

Modifying a car for the track may mean that it no longer complies with the legal requirements for the road. For this reason, serious modifications should be undertaken for track use only.
