Each car enthusiast has his own reasons why he wants to "raise" the power of his iron "horse". Someone is fond of auto racing, someone just loves fast driving. There are many ways to increase engine power, each of which differs mainly in the cost of upgrading the powertrain. But before choosing any method, one should not forget that such alterations of serial cars increase fuel consumption, and in some cases reduce the service life. And yet, how to increase engine power? Several methods are discussed below, ranging from the most common to the less well-known.
Increase in volume
To achieve this, the cylinders are bored at the same distance, thereby increasing their volume. This method is quite common and not very expensive. Indeed, the amount of horsepower increases and the torque increases, but not much. In addition, the intake and exhaust systems will not be able to work effectively, because due to the increased volume, they will not have enough "strength" to fill the cylinders with fuel and remove the exhaust gases as before. To eliminate this, it will be necessary to increase the piston stroke, that is, it will be necessary to change the connecting rods. If you want to achieve more effect, replace the standard cylinder head gasket with a thinner one. You can also trim itself by increasing the compression ratio. The addition is effective, but laborious, and requires replacement and adjustment of some units.
After finishing work, you will increase the number of horses in the engine and achieve higher torque. However, you will have to fill in with a higher octane number: if there was a 92nd, you need to fill up with a 95th, and if there was a 95th, then a 98th. Increasing the engine size can be a good start for deeper transformations.
Installation of lightweight pistons or rings
This means forged items. They are very durable and lightweight. However, such an increase in engine power can cause a number of problems:
- disassembly of the power unit and the installation of new parts into it must be done at a high professional level;
- contacting specialists will force you to shell out a decent amount;
- in the course of the alteration, it will be necessary to modify the brake, exhaust, intake systems, as well as the gearbox.
Replacing the factory flywheel with a lightweight one
The idea is that this part, having less weight, spins the crankshaft faster, ensuring that the desired rpm is achieved efficiently. The level of increase in engine power is 4%. A lightweight flywheel is inexpensive, and it's not difficult to install it: if you have experience, you can do it yourself.
Installing a Zero Air Filter
The essence of the revision is to reduce the resistance to the air flow entering the cylinders. The fact is that the standard part is made of a durable material that does not allow a large volume of air to pass through. But it is best to install a zero resistance filter in a "set" with other upgrades, otherwise it will give a minimal effect. Do not forget that the filtering ability of such a part is worse than that of a standard part.
Chip tuning (reprogramming)
The method is simple: you don't need to open the motor and you don't need to buy anything either. If this business is entrusted to a specialist, the power plant will fully reveal all its capabilities that the automaker hides in order to increase the life of the car. The increase in engine power will be 10-15%. Most often, tuners increase the amount of fuel supplied.
The engine will become stronger, and the emissions into the atmosphere will be more harmful. You can also unlock the crankshaft speed limiter. For example, once a non-turbocharged Honda developed a capacity of 160 hp. with. with a cylinder volume of only 1.6 liters. This was achieved by spinning the engine up to 8 thousand rpm.
Installing a nitrous oxide cylinder
This method allows you to get a sharp acceleration, but only for a short period of time. The cylinder is connected to the fuel system: nitrous oxide contributes to the formation of more oxygen, which "forces" the fuel to burn better and faster. The method is especially good for sports cars, for which a short-term breakthrough often decides everything. Disadvantages of the method:
- high cost of components;
- decent cost of work;
- reducing the resource of the motor.
Using turbocharging
It is considered one of the best methods to increase the amount of horsepower in the motor. Many car manufacturers already equip their cars with turbines at the factory. If you have just such a machine, then to increase the power, it is enough to install a stronger unit: the operation is not very complicated, it requires a minimum of modifications. The situation with atmospheric cars is more complicated. This means not only the installation itself, but also the operation:
- air and oil filters will require more frequent replacement;
- the engine will also have to be warmed up in warm weather.
As for the installation on the "aspirated" of the described unit, do not forget about the additional cooling of the turbine: usually they use an intercooler, increase the volume of the coolant, and increase the fan performance. Plus, you will have to supply more efficient nozzles.
Exhaust pipe replacement
This refers to the installation of a direct-flow part that does not have a resonator. This reduces the muffler's resistance to exhaust gases, which travel much faster. As a result, the power plant spends less "effort" to remove exhaust gases from the exhaust system and more energy to spin the crankshaft. Increase in power - up to 15%. Not bad at all, but:
- engine operation will be accompanied by an unpleasant loud sound;
- the increased content of harmful substances in the exhaust worsens the ecological situation.
Replacing regular engine parts with sports ones
The idea is to replace factory parts with sports car counterparts. Such an operation will allow the technical parameters of the power unit to be raised to the maximum height. However, it is worth remembering: the car must be adapted to different loads. We'll have to change the gearbox, redo the brake system. The advantages of this method include the preservation of the engine's factory resource and the same fuel consumption.
Replacing components with better ones
It is known that spare parts from different manufacturers are installed on manufactured cars, and sometimes not the best ones. Therefore, if you put the highest quality components on the engine (candles, high-voltage wires, oil filters, air filters, etc.), you can achieve an increase in power by 4-5%. But this approach is true for inexpensive cars.
Increasing the power of the diesel unit
Diesel, when compared with a gasoline engine, has a number of advantages: economy and relative "tolerance" to fuel quality. The diesel engine pulls better on the "low". As for increasing power, most of the methods listed above are applicable to a diesel engine: cylinder bore, turbocharging, chip tuning, etc. But there are also features of improvement.
Modules for increasing power characteristics
These are specially designed blocks that interact with the vehicle's fuel system. They do not affect the operation of the electronic control unit in any way, they simply exercise additional control over the operation of the electronic sensors. There are four types of modules:
- A block that changes the pulses that control the operation of the injectors. Here the task of the module is to slow down or speed up the lifting of the needle. This reduces the consumption of diesel fuel and improves its combustion. This happens due to a change in the ignition timing. The module is easy to install and can work with any modern diesel units.
- A block that affects the operation of the high pressure fuel pump. The module operates in conjunction with a sensor that provides information on fuel pressure. At the same time, the data are underestimated. This leads to an increase in pressure in the injection pump. As a result - the preservation of the operational resource of the power unit while improving the dynamics. The unit works only with diesel engines that use a mechanical method of supplying diesel fuel and manufactured before 2008.
- A block working with a fuel rail sensor. This module is also engaged in "cheating", supplying data to the ECU on the pressure drop in the rail. He begins to "think" that the dynamic characteristics of the motor are insufficient and changes the intensity of the functioning of the injectors. Power increases and fuel consumption decreases.
- A module that optimizes the operation of the ECU (more precisely, its processor). The purpose of the unit is to determine the pressure in the fuel system. If its value is large, a signal is sent, "ordering" to increase the timing of the injectors. That is, the module is able to change the engine operating mode without the participation of the electronic control unit. The unit is not "engaged" in the delivery of false information and is installed in the high pressure system. Works well with any modern diesel installation.
The advantages of the above units include ease of installation, savings in diesel fuel consumption and an increase in power. However, this reduces the service life of the cylinder block, injectors, and the fuel pump. At the same time, the emission of harmful substances into the atmosphere increases.
Common rail
The task of this system is to supply diesel fuel to the combustion chamber, regardless of the engine power at the moment and the torque. In a conventional diesel, fuel is compressed in the intake manifold, while in common rail this happens when the composition is fed into the combustion chamber.
: In short, an air / fuel mixture is injected into the combustion chamber, which then explodes, pushing the piston downward. It would seem logical that in order to increase the power of such an engine, either an explosion is needed more powerful, or the combustion chambers are larger or larger in number. But it's really that simple - there are many ways to increase engine power. Some of these methods are available, others are not, some of them are legal, some are illegal, some are cheap, others cost a lot of money.
In fact, for a small increase in the power of the car - in other words, to make it speed and accelerate faster, which many car lovers want, and some just crave - you just need more efficient fuel combustion, a little more fuel (and air, respectively). Ultimately, instead of changing the engine of your car, the key and much cheaper way can be, for example, simply improving the air-fuel mixture or more of it in the combustion chamber. And you can also add additional substances to the fuel, for example, additives or nitrous oxide.
Here are five of the best ways to boost your car's engine power. Note that sometimes it is actually cheaper to use these methods of increasing power to change the engine itself. Still, this method is far from always the best.
Turbine to increase engine power
The supercharger serves for, in fact, forcing air through the air intake much higher than the normal atmospheric level. Thus, much more air can enter the motor, which gives the freedom to increase the amount of fuel that can be burned completely, thanks to the right amount of air. All this will lead to a significant increase in power.
Taking over the drive mechanically with a belt or chain from the crankshaft, the turbocharger spins at a mind-boggling speed of at least 50,000 rpm (much faster than the engine itself - take a look at the top of your tachometer to roughly compare rpm) ... All this is just to force more air into the combustion chamber.
Nearly 50 percent more horsepower if the turbo is properly set to match the performance and design of the engine itself.
Keep in mind that turbocharging is quite expensive. For example, on a VAZ, a turbo kit (a ready-made set of turbines for installation) will cost about 70-100 thousand rubles along with the installation work. In addition, it is believed that the presence of a turbine significantly affects the service life of the engine and the wear life of its critical parts to a lesser extent.
Sports air filter as a power boost
Sports air filters are correctly called " air filters of zero resistance"They allow more airflow to enter the engine for more efficient use of the air / fuel combination, while blocking contaminants and impurities from entering the engine."
Sports air filters usually consist of a thin layer of special material sandwiched between layers of mesh. The essence of their work is in the principle that the air entering the engine must get there freely. A conventional paper air filter has the ability to resist the flow of air through it, resulting in much less air entering the motor. And the sports filter has almost zero resistance to air flow, which adds even a little more power to the engine.
How much does the engine power increase? Nothing at all - about 3-8%, but the reviews of the owners indicate that this is still a noticeable increase in power.
Such a small increase in power is compensated by the low cost of the "zero" - often the price for such an air filter is not higher than the usual original filter for a car.
We increase the power by cooling the air
While this may seem like a small detail, air temperature can affect the efficiency of your engine. Another odd but good way to increase engine power is with an air cooling kit, which serves one single purpose - it cools the air that enters the combustion engine.
Air cooling systems can lead to improved engine performance and efficiency based on the idea that colder air is denser than warmer air, which means that it contains more oxygen needed for more dynamic combustion of fuel in the engine.
How much does the engine power increase? Alas, although the air cooling kit is inexpensive, its installation requires significant changes in the motor design. As a result, the power increases, although noticeably, but not much.
Chip to increase motor power
If you have a not quite old car and not the cheapest one, then it is very likely that you have an on-board computer, controlling such functions as the synchronization of the various engine components, the concentration of the air and fuel mixture, the ignition timing, and the like.
"Chipovka" a car is a software redefinition of the factory settings of the engine for different purposes - most often to increase engine power or (less often) to save fuel. Chip tuning through a computer with a specially installed program, connected to the connector of the on-board computer of the car, sets new parameters for various engine functions of your choice. For example, "chipping" tells the car engine to use gasoline a little more efficiently or to set the ignition timing to an earlier stage.
How much does the engine power increase? Chip tuning is a fairly inexpensive way to increase engine performance. Depending on the car model, this type of tuning can cost from 3-4 to 12-20 thousand rubles. But often, especially in small towns, it is not easy to find a competent "chip maker" for a particular car model. You can try to "chip" the car yourself, but this will require some training and understanding. In some cases, it is even possible to spoil the engine with such independent work.
Reducing weight - increasing dynamics
A simple alternative to increasing engine power is to reduce its weight and, as a result, improve dynamics.
Light things can accelerate faster than heavier things - the foundation that physics gives us. This solution is both low-tech and efficient at the same time. It's hard to believe, but even a removed spare wheel will improve the dynamics of the car. However, the owners of low-power cars, who at least once drove loaded only with passengers, will believe this.
There are many options for losing weight. The advantage of this method is also in the fact that you yourself choose how expensively you will reduce weight. After all, it is one thing to unload the trunk from unnecessary trash, and quite another thing - for example, replacing glass windows with lighter plastic or acrylic ones, or changing drum brakes to disc brakes. Also, the replacement of rims leads to some improvement in dynamics.
Many motorists are interested in how to increase the engine power of their own car. Some dream of high speeds, others are fans of sports hobbies. There are many options available to increase power while maximizing speed. The difference between them is in price and efficiency.
However, it should be remembered that more power makes the car more "gluttonous", and this does not suit everyone. Therefore, making such a decision, you should carefully analyze each method separately, making appropriate conclusions.
Power addition options
We reduce the weight of the car
To do this, heavy parts are replaced with analogues made of light, but very durable material. This method allows you to reduce fuel consumption, improve handling, and increase dynamics. But, to the question whether it is possible to improve the functions of the engine thanks to it, the answer is unequivocal - no.
Installing a zero resistance filter
The simplest and most inexpensive method applied to sports cars. The filter has maximum cleaning power and does not resist the passage of air. This speeds up its access to the combustion chamber, contributing to the efficient use of gasoline and a significant increase in engine power.
Thanks to the ability to clean, the filter does not need to be replaced, which allows you to significantly save your budget. However, this method does not allow achieving a significant increase in power.
This is a really effective option that requires minimal investment. It consists in increasing the volume of the cylinder block by boring. Due to this, the connecting rods, as well as the pistons, are subject to changes.
This technique does not guarantee that the increase in power will justify the expected result. It is possible that with insignificant changes, fuel consumption will increase quite impressively.
We install sports counterparts to standard parts
Thanks to forged pistons, it is possible to significantly increase the load on the engine. This increase in engine power provides an opportunity to achieve the expected results, squeezing the maximum out of any unit.
But, in this case, you will have to replace the brakes and the gearbox (gearbox), which need to be adapted to new loads. The advantages of this technique include maintaining fuel consumption within the same limits, as well as an increase in the operating period due to the use of high-quality parts.
Reprogramming ECU (electronic control unit)
Almost all cars with injection engines are equipped with a control unit with a specific program of work. Despite a number of restrictions put forward by the ECU to the specific characteristics of the engine, they can be successfully circumvented.
Programmers have their own way of doing this, allowing them to introduce new parameters into the car's "brain". Thanks to computer technology, such chip tuning gives effective results.
Carrying out such a procedure yourself is not recommended. This can lead to a program failure that could damage the unit. This work should be done by professional programmers!
We replace the exhaust pipe with a direct flow
Interested in how you can increase engine power, you should pay tribute to this not quite standard technique. It is able to add about 15% to the maximum power at insignificant costs, it consists in the installation of a direct-flow pipe to the exhaust system.
This helps to reduce the resistance of the outgoing gases, which significantly speeds up the movement. Thanks to this, the engine's energy consumption for exhaust gases is reduced, and is redirected to efficient acceleration of the crankshaft. The payment for such a pleasure will be unpleasant noise and too dirty exhaust, polluting the surrounding air.
Install nitrous oxide
Many moviegoers are familiar with a substance called nitrogen. The cylinder installed in the car is activated, which gives significant acceleration. However, not for long. This technique is extremely simple, but the short duration of action and the high cost of the components are a significant disadvantage.
Ways to increase engine power include installing a turbocharger. The exhaust gases passing through the turbine are accelerated by a specialized fan that pumps large volumes of air to the combustion chamber. The driver thrusts the gas harder, the number of revolutions will increase faster, which is quite noticeable.
True, in this case you will have to use a more reliable cooling system. Despite the fact that installing a turbine is quite expensive, it will help to significantly increase the potential of the engine with your own hands. The disadvantages include the increased "gluttony" of the car.
Despite the seeming simplicity of tuning a gasoline engine, it is advisable to entrust the work to specialists from the car service sector. After all, structural changes to the power unit are a serious revision that can affect numerous parameters. If performed incorrectly, there is a risk of accelerated wear of the chassis, as well as the transmission.
Speed up the diesel engine
Diesel engines are fundamentally different from gasoline engines in the technology of combustion of mixtures, which in the first are ignited with the help of electric discharges. In diesel engines, the strongest detonation occurs after powerful compression.
This property does not allow some of the above methods to be applied to them, since the diesel becomes unsuitable for upgrades. Considering this, the cost of carrying out improvements will be much higher.
The features of the modernization of diesel engines include the following.
- All modern diesel units provide for the presence of a turbine in the design. Therefore, modernization consists in replacing it with a more powerful one.
- The completion of the cylinder head, as well as the start-up, is replaced by the installation of improved systems for fuel supply, among which CommonRail is very popular. This is a rather expensive type of tuning, but effective.
- Chipping is used similarly.
Diesel engines with their intake system have more complex devices than gasoline ones. Therefore, you should not expect a super increase in power without a professional engineering approach. However, the cost of the upgrade is so high that many car enthusiasts prefer to buy a car with more power.
A budget option
If you want and can increase the engine power, you should seek the help of professionals in a specialized tuning studio. If you have an equipped garage, you can achieve improvements on your own, but this will require certain knowledge and professional skills.
After all, there is a considerable difference between grandfather's penny and a modern expensive car, and without the appropriate skills, you can not improve the performance, but harm the car.
If you remember how long ago diagnostics were done, candles, filters, and also fluid were changed, space investments will not be required to increase power. By cleaning the throttle valve, checking the compression of the engine, cleaning the intake, you can significantly increase the dynamics of the car, increasing the power. Fuel quality is also of great importance.
Possible consequences
For units that have received changes, the resource is significantly reduced. Therefore, frequent diagnostics and installation of expensive parts will be required. Having compared the desires with the possibilities and assessing the cost of the upcoming modernization, perhaps the best option would be to purchase a new car with a more powerful engine.
Major improvements lead to increased fuel consumption. This should also be taken into account when deciding on tuning.
Often the standard technical characteristics of the power unit are sorely lacking for a pleasant and safe trip. Good power is the ability to quickly accelerate if necessary, to quickly overtake a long vehicle, and also to get real pleasure when pressing into the seat after pressing the accelerator pedal.
But it is not so easy to increase the engine power, because the plant that manufactured this unit ensured its harmonious operation, taking into account the durability, certain wear and tear and fuel consumption. There are two correct ways to increase engine power, but each of them affects not only the amount of horsepower, but also other important functions of the car.
Mechanical engine tuning - increase power
In this case, the main task is to purchase high-quality parts that will be used in the alterations of the power unit. If you buy spare parts from bad metal, then after a few thousand kilometers of operation you will have to invest a lot of money to rebuild the engine.
Such tuning is often performed not just if you want to increase the power of the power unit, but if you need to overhaul the engine. Then the cost of work will not be so high, because overhaul without increasing capacity is quite expensive. The process can be based on several aspects:
- boring the cylinder block to a larger volume;
- replacement of pistons with the appropriate size;
- replacement of connecting rod shafts for a longer piston stroke;
- integration of the fuel system with a more powerful vehicle;
- professional tuning of the engine at the stand;
- making the appropriate changes to all control systems.
After such tuning, the car will become an order of magnitude more powerful, increase the number of cubes in the engine and the horsepower under the hood. But the fuel consumption will also increase. You will get a unit with improved characteristics, but you will have to travel to refuel more often.
It is important to perform this procedure only with specialists. Tuning an engine not at a professional service station will bring many troubles, among which are the rapid failure of parts and the inconsistency of the operation of all units. For example, you need to correctly calculate the required volume of the battery and the correct operation of the generator.
Chip tuning - increasing engine power by software methods
This variant of the development of the vehicle's capabilities is performed not by completely disassembling the power unit and replacing certain spare parts, but by changing the engine function control program. This helps to increase the flow of fuel into the combustion chamber and makes the unit work harder.
Of course, this method has certain benefits. You don't have to pay a lot of money to flash your computer, and this process takes only a few hours. But the disadvantages of chip tuning are more significant than the benefits obtained from this process:
- your car will consume much more fuel than a car with the same factory power;
- the gearbox will be tuned rather strangely, the engine will either have to be turned too much, or drive at a reduced speed;
- the electrical system will often drain the car's battery;
- the wear of the engine and all other units and components of the machine will be much greater.
During the design of the car at the plant, they thought about how to build the chassis, which hub bearings to use, and so on. These features were calculated solely by means of the rated power of the machine and the loads on all nodes. By changing the power, you also change the load on the unit.
Chip tuning of the engine can be done at a time when the car has not traveled more than 50 thousand kilometers. Otherwise, such a step can cause permanent serious malfunctions in the power unit system.
What methods of increasing power don't work?
There are many ways to increase the amount of horsepower in an engine, which do not help to get results at all, but are actively sold in car markets and in stores. There is also a certain number of myths among motorists, and these myths give rise to ill-conceived actions with a negative effect on the car. Among such misconceptions, the following points can be found:
- too frequent oil change - if the oil travels in the engine for more than 15 thousand kilometers, the unit really loses power, but too frequent replacement can only do harm;
- various fuel additives, which are designed to increase power, will only help you bring the engine to a major overhaul faster;
- an increase in the number of revolutions by adjusting the power unit will cause increased wear and excessive fuel consumption, and such a step will not increase the power.
You can also increase the number of engine revolutions by depressing the gas pedal more intensively. But this does not increase the power of the engine, but simply makes it work harder, which increases consumption. Therefore, you should not believe in various devices, additives, expensive oils and additives in different engine systems, which promise an increase in power by a certain percentage.
The manufacturer has supplied your car with a sufficient number of horses, and it can only be increased by investing heavily in the power unit.
We offer you to watch a fascinating video about chip tuning of a domestic car:
Summing up
A huge number of motorists today are thinking about how to increase the engine power in their car. Remember, there are no harmless ways to get more horsepower. You will reduce the life of the power unit, you will start spending more money on a car, not only at gas stations, but also during maintenance.
Therefore, think carefully before deciding to increase the engine power of your car. You can find many pros and cons in this process, so weigh the pros and cons. Have you ever come across ways to increase the power of a powertrain?
There are 2 ways to increase torque and horsepower: chip tuning without interfering with the design of the power unit and forcing the motor with subsequent reconfiguration of the ECU software. Consider how to increase engine power and whether you can do it yourself. Let's talk not only about injection and diesel internal combustion engines, but also VAZ engines with a carburetor.
CHIP TUNING
Changing the software of the electronic engine control unit is ineffective on naturally aspirated gasoline engines with distribution injection on the valves. The amount of air entering the cylinders, and it is this parameter that is important for increasing power, is fairly accurately calculated during the design and testing of the engine. Therefore, it is impossible to achieve a significant increase in power by programmatically changing the injection angle, ignition timing, and the amount of fuel supplied. Also, engine chip tuning does not work on old diesel engines that have a minimum of electronics.
Modern turbocharged engines are different. Software adjustment of the moment and angles of injection, ignition, the amount of fuel supplied to the cylinders, a change in the algorithm of the turbocharging operation makes it possible to obtain an average of 10-15% of the standard engine power. 
CAN YOU MAKE YOUR OWN HANDS?
Having a technical mindset, a confident understanding of the gas exchange processes inside the engine, a lot of time and free funds to buy basic equipment, you will be able to do chip tuning on your own. The easiest way is to find a ready-made firmware for your engine model and "fill" it into the ECU. If we are talking about an independent software change, setting in dynamics, then even a practicing diagnostician-auto electrician will need a lot of time to study the issue.
REMOVAL OF ENVIRONMENTAL "COLLARS"
- Physical removal of the catalyst (in the presence of a second lambda probe, it requires a software update). A serviceable catalyst creates a small backing of the exhaust gases at the outlet, but in a clogged state it significantly impairs the filling of the cylinders at high speeds. An even greater loss of power is felt on diesel engines. Particles of soot, mixing with oil vapors, clog the honeycomb of the particulate filter.
- Programmed change of response to the gas pedal. This will not add power to the engine, but the feeling from the acceleration dynamics will change for the better.
Changes in the intake system, exhaust system, cylinder head or engine block on injection and modern diesel engines must be accompanied by online tuning. Without changing the ECU software, you will not get a good increase in power and proper engine operation.
BASIC FORCING MOTOR
There are only 5 ways to increase the power of the internal combustion engine.
Lubrication and Cooling
The dramatic increase in power puts additional demands on the engine's lubrication and cooling system. If possible, it is worth installing an oil pump with increased performance. If you are going to increase the power of the engine with high mileage, be sure to carry out a troubleshooting and, if necessary, replace the oil pump. Install an oversized radiator to prevent engine overheating.
INLET AND EXHAUST SYSTEM
The volume of the receiver, the length and flow area of the channels of the inlet and outlet systems directly affect the filling of the cylinders. One of the first steps in increasing engine power can be considered the installation of an equal length exhaust manifold 4-2-1 or 4-1. To get the maximum output, it is necessary to install a forward flow, but this will increase the noise level. Therefore, for civilian use, we recommend slightly increasing the flow area of the exhaust pipe and installing a more sporty muffler. This will reduce the resistance of the exhaust system to the outlet of the exhaust gases. 
Installing a zero resistance filter is one of the most popular ways to increase engine power. This move allows you to get no more than 1-3%. Competent installation of a zero-wheel requires the implementation of a cold air flow, which is implemented from the factory on many cars with standard air filters. Without this, the engine will suck in heated air from the engine compartment, which will worsen the filling of the cylinders and reduce the performance of the engine.
We will not consider the installation of the throttle inlet in detail, since this method of increasing power can hardly be called civilian.
TURBOCHARGING
For additional injection of air into the cylinders, the following are used:
Which of the turbocharging systems is best for your car depends largely on the engine model, the layout of the engine compartment and the availability of ready-made solutions. For example, for VAZ engines, options for installing both a turbine and a mechanical supercharger have been developed in some detail. 
Installation of a turbine or a supercharger requires a preliminary reduction in the compression ratio, installation of an intercooler; it is obligatory to switch from DMRV to DBP + DTV. The thermal balance of the engine changes, which requires more performance from the cooling system. To prevent burnout of the pistons, and to reduce the risk of detonation, it is necessary to install pistons with oil nozzles.
VOLUME, DEGREE OF COMPRESSION
The more air-fuel mixture burns in the cylinders, the more power we can get from the engine. You can increase the volume by bore-out the cylinder and installing larger pistons or increasing the diameter of the crank. An increase in the travel of the connecting rods leads to an increase in torque at the bottom. But at the same time, there is an accelerated wear of the CPG, since the pistons at the time of shifting exert more pressure on the cylinder walls. Due to the large loads on the CPG, the crankshaft, liners, an engine with a long piston stroke cannot be high-speed.
It is desirable to increase the compression ratio only in combination with other engine modifications. But the method will significantly increase power only on old engines with carburetors, which were designed to work even on AI-86 gasoline. The more the air-fuel mixture is compressed, the more torque can be obtained from its combustion. But keep in mind that the higher the octane number of gasoline, the more expensive it is, besides, after an increase in power, fuel consumption will definitely increase. Therefore, it is simply impractical to switch to gasoline with an octane rating of more than 98 for civilian use.
The use of spark plugs with a low glow number, the engine runs on gasoline, the octane number does not correspond to the compression ratio, leads to detonation
TUNING CYLINDER
The video shows the basics of revising the cylinder head, which will allow you to increase the power of an atmospheric and turbocharged engine with your own hands.
