You can make your car more powerful by two methods. The first is simply to have good driving habits. The second involves modifying the original components of your car.
These simple steps to improve engine performance
To make your car more efficient or at least prevent it from regressing, it is enough to carry out regular maintenance. Servicing the engine at regular intervals will keep it in good shape.
Among the most important elements in the engine is oil. It lubricates it and limits friction. This reduces the efforts of the latter. It also regulates its temperature and allows it to function optimally. In addition, the oil has anti-corrosive properties which extend the life of the engine. It removes the impurities present by taking them to the filter.
When the oil is used, it prevents the engine from running at full speed. When it is in low quantity, it can damage it, and in excess, it causes its dysfunction. The motor oil plays a fundamental role in the performance of it and should be changed after 15 000 or 30 000 km of use.
To take advantage of the full power of your engine, you will also need to use good quality oil. Using one that has a different property from that recommended by your manufacturer may also cause your car to lose power. Using questionable additives or mixing oils will also not help you improve the performance of your vehicle.
Other more unsuspected elements can also give more power to your engine. These are the tires. When properly inflated and with better grip, these can reduce engine stress. There are tires suitable for each type of road in this case and tires intended for performance.
Prerequisites before starting to modify the engine
Before making any modification to the components of your car, you should be aware of what this entails. A modified car may no longer comply with the standards in force for a petrol engine. As a result, there are risks that in the event of an accident, your car insurance will not be usable. To avoid this kind of inconvenience, the modification of the power of your engine must be done within a legal framework. Administrative forms must be completed before this increase in power can be carried out. The modifications must also be made by a professional with an authorization from the manufacturer.
An analysis of the power requirements of the user and the risks incurred as a result of the alteration of the original installations will be necessary. The professional can thus add parts, modify the pre-installed elements or replace them with others. It will also make modifications to the electronic system used by certain models to restrict the engine. If the modifications are carried out in the rules of the art, the engine can obtain a power gain of up to 30%. Consumption could also drop by 15%.
Improve air intake
All internal combustion engines operate on a single principle. Air (oxygen) is mixed with fuel in the combustion chamber to generate engine power. Pressurized air must therefore be constantly mixed with the fuel to maintain engine performance. The air must be clean enough to optimize combustion, hence the importance of the air filter. It would suffice in this case to have one that is properly configured to gain power. When the filter is calibrated to the maximum, it will let in fewer particles and less air. If it is too passive, the air will arrive in great quantity and it will be the same for the particles. So you have to choose the right balance and change the filter regularly.
By allowing more air to enter the combustion chamber and injecting more fuel, it is possible to increase the power of the engine. These two elements must however be dosed properly so as not to lead to overconsumption. An electronic device or a computer is normally responsible for balancing the air-fuel mixture.
By modifying the controls used to control the operation of the engine, it is possible to achieve the perfect dosage and obtain a power gain. To increase the amount of air, simply widen the vehicle’s air intake at the front. It will then be necessary to widen the exhaust duct. Indeed, gas is generated after combustion and if it is not evacuated properly, it may limit the entry of air and slow the engine. Especially since with more air and fuel, there will be more exhaust gas.
Addition of turbocharger or turbo
The turbocharger also aims to improve the oxygen supply in the combustion chamber. It uses exhaust gas to turn a turbine connected to a propeller by the same axis. The rotation of the propeller is used to feed the air intake and increase it in the intake manifold. Air collects there and eventually compresses. However, it heats up when it is compressed. As a result, it expands and thus takes on more volume. To reduce this volume, simply lower the air temperature with an intercooler. Before entering the combustion chamber, the compressed air will be cooled.
In addition, to avoid overpressure of the intake, the system called Wastegate can be installed. It can be integrated into the turbo or installed separately. Its operation is automated thanks to the electronic systems available to modern cars. Changing the behavior of this system to improve engine performance is part of the reparameterization of the engine mapping.
Note however that the turbo is different from the compressor. These two systems work similarly except for one detail. The compressor uses the rotation of the motor to rotate the propeller which increases the air intake. It is therefore more limited in terms of speed, since the engine can only run at a few thousand revolutions per minute. However, the turbo turbine can reach 200,000 revolutions per minute. Despite everything, the compressor allows better air intake even at low speed.
