Tuning a car is not only an external change, but also an internal one, much more under the hood. Let's talk about the ways to improve the engine and their consequences.

The majority of people, as soon as they hear the word "tuning", immediately think about the external modification of the car. Although motorists will argue with this, because they know that this concept affects both the improvement and repair of the external elements of the machine, and directly the internal parts and systems. It is worth recalling that an important component of any transport is the engine and its operation.
About important nuances in the operation of the unit
Perhaps every driver and car owner wants his vehicle to dominate even more power and speed, and this despite the fact that it already has an inherent number of "horses" under the hood. And if there is a desire to further increase the engine power, then it is worth noting that this process can be done at home without extra costs for work at a service station or in a service center.
Before proceeding with the process of increasing engine power, it is necessary to take into account some of the nuances. The first rule in such an improvement is the fact that the more powerful the engine, the more it will need to spend on fuel, because its consumption will increase. In addition, after the improvement, the engine will need a higher quality fuel, which naturally has a high cost.
After the process of increasing engine power, there is another not very pleasant nuance - it will wear out faster than it was before the improvement. You will also need to change the oil in the system more often than before.
Still, these works to increase engine power are best carried out at a service station, because there the specialists know their business. And when the desire arose, you can improve at home, you just need to adjust yourself to the fact that you need to purchase high-quality fuel and increase the volume of filling the cylinders.
On the process of increasing engine power
Each driver comes up with different ways to increase the power of the engine of his car. From the installation of accessories, to a complete overhaul of the engine. As an example, consider the most common way - increasing power through the exhaust system and air filter.
For the exhaust system, we need a straight-through jammer, which will be larger in diameter than the standard one from your car. This is done so that your car's engine runs faster, can withstand higher loads, and as a result, the flow of exhaust gases is reduced. In other words, the faster the exhaust gases come out, the faster a few horses will be added to the engine power. Typically, forward flow adds 9 to 12 horsepower.
Such a change in the exhaust system often makes it necessary to change other parts of the engine. In this case, the air filter, the air must flow freely without any obstacles. According to experienced tuning enthusiasts, it is best to buy an exhaust system with a muffler that is 3 inches in diameter. Sports air filters are installed in tandem with the tuned exhaust system.
This type of filter is good, but it is worth remembering that a sharp stream of hot air at a high temperature will reduce the efficiency of engine rework. To avoid such problems, an additional device is installed to cool the intake air.
Car wiring and spark plugs play a significant role, often good wiring will withstand any load as the power increases. Spark plugs, in turn, ignite the fuel mixture well, which means that you should not save on them either and, if possible, replace them with high-quality ones.
Adding displacement to the engine
In addition to the above method, you can go another way, by increasing the engine displacement. Experts identify two options for solving this problem. First of all, this is the boring of the engine cylinders, the second method is replacing the engine crankshaft. Each of the methods is good in its own way, but considering the financial costs and laboriousness of the process, the first method is much more profitable than the second with the replacement of the crankshaft.
If you chose the first method, then you will need to bore the cylinders, then select and buy new pistons and rings for the bored diameter, and all this costs money. The second method is difficult in that you will have to look for a crankshaft with a long stroke, since they are made in very small quantities, and the price for them is high. Plus, the replacement process itself is not easy and requires a lot of time and nerves, if you do not change yourself, then a decent amount of money for replacement.
Combustible mixture in cylinders
It's no secret that a good and rich fuel mixture in the cylinders is the first guarantee of success and engine power. But also when the mixture is more combustible, the engine increases performance. In order to increase the coefficient of filling the engine cylinders with a combustible mixture, some craftsmen think of reducing the aerodynamic resistance of the exhaust and intake systems.
The circumference of the gas channels is also increased, in particular, the diameter of the valve discs is increased. As a result, the engine speed will increase.
Fuel compression level
Many people know not from rumors that the stronger the combustible mixture is compressed, the greater the speed and efficiency will be during the combustion of the mixture. To do this, most often grind the surface of the head or select a thin gasket, in comparison with standard units.
A slight decrease in the distance will give more power to the engine, but you should be very careful with this, since grinding the head is delicate and without practice it is better not to start the process.
Mechanical malfunctions of the unit
When thinking about tuning an engine, first of all take a closer look at how it works. Is everything in order and is there nothing to clatter. Usually, minor mechanical failures can also lead to a decrease in engine power.
Most often it is worth looking at cylinder breakages. Rings may wear out, the system may not cool well, or compression may disappear altogether. Usually then the rings and other small parts are first revised, and only then resorted to head melting or the like. Sometimes, when repairing a piston, a connecting rod is installed in a standard length, this also gives power to the engine.
Engine tuning cost
If you decide to add horses to the engine, first of all think about how much it will cost you. The exhaust system can be expensive to buy, but it will not always fit your vehicle well, so reconsider and choose an average. The price for direct flow will average from $ 50, some models may be more than $ 1000. The entire exhaust system will cost from $ 100.
If you take the grinding of the cylinder head as an option, then only for the work you will have to pay about $ 100, not counting parts and parts for replacement. Therefore, it should be understood that the greater the desire, the more expensive it will cost. Above are the most common ways to increase engine power, and this does not limit the imagination of car owners. Everyone comes up with a new way, and the options are better and better improving the existing one.
