Horsepower is similar to money in many ways in that a car owner can never have too much at his or her disposal. However, if it is not used wisely, it can lead to a lot of trouble. For do-it yourself vehicle modifiers wishing to get the most horsepower from their money, extra muscle will always be a welcome addition to any car engine. Below are ways of boosting horsepower that fits all output levels and budgets. All the car owner has to do is make sure all engine modifications made are street legal and that the car has adequate insurance, including car trade insurance.
Cold Air Intake
Systems of aftermarket air intake are among the least expensive and most commonly used ways of increasing horsepower. They consist of simple bolt on kits made up of a conical air filter that is fixed to a metal inlet pipe. Once installed, this inlet pipe begins from the engine’s top and goes all the way to the outside of the engine bay. The conical air filter is connected to the pipe’s lower end and can now take in the air below the engine that is cooler compared to that being inlet by the stock air box. The system set up is known as cold air intake since cool air has more oxygen molecules than warm air, thus has more powerful combustion if mixed with fuel. The gain in horsepower varies, depending on the engine it is connected to and the intake brand. Typical gains range between 5 and 20 horsepower.
Superchargers and super coolers are forced induction systems capable of boosting engine potency significantly. The two systems work under a similar principle where air is compressed and fed into the engine. In a turbocharger, a turbine is spun by the hot air from the exhaust manifold that in turn runs the air compressor. On the other hand, in a supercharger the compressor is driven by a belt connecting to the engine directly. Air is made more oxygen-dense by compressing it, making it possible for the engine to increase fuel in pistons, thus increasing output.
Systems of stock exhaust restrict engine exhaust flow, robbing the car of both fuel economy and output. Performance exhaust pipes give a flow rate that is optimum, which is not the case with factory pipes, since they have a much larger diameter and no bends and kinks. Therefore, this problem is addressed by aftermarket exhausts through allowing exhaust fumes to flow in a freer manner. This reduces the back pressure generated, providing the power carved by car owners.
Nitrous Oxide System
Basically, a nitrous oxide kit is made up of a source of compressed liquid nitrous oxide connected to an intake manifold. All the driver has to whenever he needs a nitrous boost is to flip a switch or press a button to direct the liquid into the engine. When injection of nitrous oxide to the intake manifold is done, it breaks down at high temperatures to yield more oxygen than that contained in the atmospheric air. The oxygen in denser concentrations enables the engine it burn more air and fuel, increasing the output.
