How to increase engine power? 5 best ways to modify a motor
The operation of the engine is quite simple: in short, an air-fuel mixture is injected into the combustion chamber, which then explodes, pushing the piston down.
It would seem logical that in order to increase the power of such an engine, you need either a more powerful explosion, or larger combustion chambers or more in number. But everything is so simple in reality - there are many ways to increase engine power.
Some of these methods are available, others are not, some are legal, some are illegal, some are cheap, others cost a lot of money.
In fact, to make a car's power a little bit more—in other words, to make it speed and accelerate faster, which is something so many car enthusiasts want and some just crave—you just need more efficient fuel combustion, a little more fuel (and air, respectively).
Ultimately, instead of changing your car's engine, the key and much cheaper way may be, for example, to simply improve the air-fuel mixture or have more of it in the combustion chamber.
You can also add additional substances to the fuel, for example, additives or nitrous oxide.
Here are the five best ways to increase your car's engine power. Please note that sometimes it is actually cheaper than using these methods to increase power to change the engine itself. But still, this method is not always better.
Turbine to increase engine power
The supercharger serves to, in fact, force air through the air intake much higher than the normal atmospheric level. Thus, much more air can enter the engine, which gives freedom for a corresponding increase in 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 drive mechanically via a belt or chain from the crankshaft, the turbocharger spins at a mind-boggling speed of at least 50,000 rpm (that's much faster than the engine itself - take a look at your tachometer's top mark for a rough comparison). . All this is just to force more air into the combustion chamber.
How much does the engine power increase? Almost 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, for a VAZ, a turbo kit (a ready-made turbine kit for installation) will cost about 70-100 thousand rubles together with installation work. In addition, it is believed that the presence of a turbine significantly affects the service life of the engine and the wear time of its critical parts to a lesser extent.
Sports air filter as a means of increasing power
Sports air filters are correctly called “zero resistance air filters”. They allow more airflow into the engine for more efficient use of the air/fuel combination, while blocking pollutants and impurities from entering the engine.
Sports air filters typically consist of a thin layer of special material placed between layers of mesh. The essence of their work is the principle that the air entering the engine must enter there freely.
A regular paper air filter tends to resist air flow through it, resulting in much less air entering the engine.
And the sports filter has almost zero resistance to air flow, which, at least a little, adds power to the engine.
How much does the engine power increase? Nothing at all - about 3-8%, but reviews from 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 “nulevik” - often the price of such an air filter is no higher than the usual original filter for a car.
We increase power by cooling the air
Although it may seem like a small thing, air temperature can affect the efficiency of your engine. Another strange but good way to increase engine power is an air cooling kit, which serves the sole purpose of cooling the air, which is then fed into the internal combustion engine.
Air cooling systems can lead to improved engine performance and efficiency, based on the idea that cooler air is denser than warmer air, meaning it contains more oxygen, which is necessary for the engine to burn fuel more dynamically.
How much does the engine power increase? Alas, although the air cooling kit is inexpensive, its installation requires significant changes to the motor design. And the power eventually increases, although noticeably, but not much.
Chip to increase engine power
If your car is not quite old and not the cheapest, then it is very likely that you have an on-board computer that controls functions such as the synchronization of the operation of various engine components, the concentration of the air-fuel mixture, the ignition timing, and the like.
“Chipping” 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 car’s on-board computer connector sets new parameters for a variety of engine functions of your choice.
For example, "chip" tells the car engine to use gasoline a little more efficiently or set the ignition timing at 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, finding a competent chip technician for a specific car model can be difficult. You can try to “clean” the car yourself, but this will require some training and understanding.
In some cases, you can completely ruin 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 be accelerated faster than heavier things - this is the basis that physics gives us. This solution is both low-tech and effective at the same time. It's hard to believe, but even removing the spare tire will improve the car's dynamics. However, owners of low-power cars who have at least once driven with only passengers loaded will believe this.
There are many options for losing excess weight. The advantage of this method is that you choose how much weight you will lose.
After all, it’s one thing to unload the trunk of unnecessary junk, and quite another thing, for example, to replace glass windows with lighter plastic or acrylic ones, or to change drum brakes to disc ones.
Also, replacing the wheel rims leads to some improvement in dynamics.

In what ways can you increase the power of a car engine?
Many car owners are thinking about ways to increase the power of their car engine. Some simply do not have enough horsepower for comfortable trips around the city, while others love powerful cars and would like to get a small increase in the form of a couple of dozen horsepower. Let's talk in more detail about how to increase the power of a car engine.
Types of car engine tuning
All engine tuning, which involves increasing power, can be divided into two main categories :
1. Software or hardware.
2. Engineering.
With the so-called software tuning, or as it is also called chip tuning, you can simply make changes to the engine control program or install an additional small box, which allows you to get a power increase of 20-30 horsepower. This version of chip tuning is simple, affordable, and later, when selling a car, you can easily dismantle such chip tuning and sell the car with a standard power rating.
Today, this type of chip tuning, due to its simplicity, efficiency and relative harmlessness to the engine, has become widespread on the market. It is used both to increase the power of new cars that are still under warranty, as well as in older diesel and gasoline cars.
When planning to increase the power of a car engine, it is necessary to remember that unqualified intervention in the power unit will invariably lead to a deterioration in engine reliability.
That’s why we wouldn’t recommend you do this kind of work yourself or trust it to garage technicians.
Only by turning to experienced tuning specialists, you can not only correctly increase the power of your car, but also receive the necessary guarantee of the quality and durability of the engine, which will practically not lose its service life.
Options for deep engineering tuning
An effective way to increase engine power is to install turbocharging, which allows you to increase engine power by 50% or more.
In this case, in addition to the turbine itself, a new injection system, a reinforced crankshaft and pistons are installed, and other necessary work is also carried out.
It should be said that despite the complexity of such an increase in engine power, installing a turbine is popular, which is explained by the excellent efficiency of such tuning.
Boring the cylinders and installing a new crankshaft. This is one of the engineering tuning options, in which the cylinders are bored, with the installation of new pistons and a reinforced crankshaft.
In fact, with such operation, the physical volume of the engine increases, which has a positive effect on its power and torque. If we talk about the disadvantages of this method of increasing power, we note the increased fuel consumption, high cost and complexity of such tuning.
In the future, you also need to be careful about engine maintenance, the service life of which will be significantly lower than that of a standard engine.
Installing a modified camshaft will allow you to adjust the valve timing, which increases engine power, without any other profound change in the design of the power unit.
The only drawback of this method of increasing the power of a power unit is the need to use gasoline with a high octane number, since otherwise detonation occurs, which can lead to a significant deterioration in engine performance.
You can increase the power of your car by using gasoline with a high octane number.
This is a quick and simple tuning method, which at the same time will require a corresponding reconfiguration of the injection system, and the pressure in a running engine increases significantly, which negatively affects its reliability indicators. Simply pouring 95 or 98 gasoline into a gas tank without any additional reconfiguration of the fuel system is not recommended.
Installing a zero resistance filter. This is a fairly simple and effective way to increase engine power by about 10 horsepower.
Due to its special design, such a filter improves the supply of the air mixture, reducing fuel resistance at the inlet.
The increase in power in this case will not be too large, but this is a cheap method that does not require contacting special workshops.
Installation of a direct-flow exhaust system. By replacing the standard exhaust system with a direct-flow one, you can get about a 15% increase in power.
In addition to directly improving the dynamic characteristics, you will be able to get a pleasant roar from the engine, and the car itself will be more responsive and faster.
Just remember that you need to install a direct-flow exhaust system that fits your car model. All such work should be performed exclusively by a professional.
Use of exhaust pipes with increased diameter. Such work will optimize the movement of exhaust gases; as a result, the engine becomes approximately 5% more powerful. It is only necessary that all elements of such a modernized exhaust system be selected exclusively by a specialist.
Installation of new pistons and connecting rods. By reducing the mechanical losses of the internal combustion engine, you can get a small increase in the power of the power unit. Typically, such work is carried out in conjunction with other tuning, which allows for the maximum possible increase in engine power.
Conclusion
Today there are many different ways to increase the power of a car engine.
You can choose either a relatively simple chip tuning, in which the control system is reconfigured or additional units are used that control the operation of the engine, or a complete engine overhaul, with the installation of a turbine, a new injection system, crankshaft, connecting rods and pistons.
In each specific case, the choice of one or another tuning technology will invariably be up to the car owner. Just remember that such work must be performed by a professional, which guarantees subsequent trouble-free operation of the car engine.

Methods for boosting the engine. Powerful engine tuning
Power tuning - increasing power and modifying the engine (increasing the compression ratio and revving speed).
There are a lot of legends about boosting an engine, there are constant debates on forums, but not everyone understands what exactly they want to get from their car, and how much it will cost, because boosting even the simplest engine (VAZ-2106, 2108 or “nines” ) is quite difficult on your own, you will have to turn to specialists.
All modifications to car components involve the expenditure of time and money, and the safety of the car owner and others depends on the quality of the work performed. Here are a few factors that need to be taken into account when thinking about engine tuning:
Axioms of engine tuning
Almost all gasoline and diesel engines are more or less suitable for boosting.
Boosting can lead to both a decrease and an increase in the engine’s service life, depending on what kind of work is being done. The service life of any engine directly depends on the operating mode of the vehicle.
If the car is operated in normal, medium modes with good oil, then the engine will last a very long time, but if it is street racing , then excuse me.
For example, if you take a factory engine and a tuning one, assembled “from scratch” in a specialized center by experienced craftsmen, then under the same operating conditions the second engine will go twice as long. This means that the service life of the tuning engine is approximately twice that declared by the manufacturer.
The reason for this is that during mass production there is simply no time to tinker with each engine, checking fractions of millimeters in the gaps, selecting pistons by weight.
This is especially true for the Russian automobile industry, where the main task is not to ensure accuracy and reliability, but to “fit” manufactured products into the so-called “tolerance field,” and this field, in turn, turns out to be very, very wide.
Having received a modified engine (especially in the direction of more dynamic driving), the car owner unconsciously begins to change his driving style, increasing the load on the engine and other components of the car (the foot itself presses on the gas pedal). Few people are able to drive a tuned car calmly, and this, in turn, reduces the service life of the car’s components.
Resource of forced engines
The engine life, and therefore engine wear, depends primarily on the degree of boost, load, operating conditions and quality of fuels and lubricants. Maximum load modes are used extremely rarely in everyday life and, as a rule, for a short time. Therefore, we can safely say that when tuning, the engine life practically does not change.
And, even vice versa, it may change upward. Engine tuning is, in most cases, individual highly skilled manual work, precise fitting, weight distribution, and balancing of the internal combustion engine. The most modern tools are used, experience is constantly accumulated and technologies are studied.
Of course, the quality of work in this case is not comparable to assembly line assembly.
Mechanical engine boost
Complete, power tuning of a car is an expensive pleasure: in addition to working on the engine, you will need to “fine-tune” the gearbox, brake system, and suspension.
So, the question naturally arises: where to start modifying the engine?
Let's start with torque. It can be “raised” throughout the entire engine speed range, increasing engine displacement (this operation is sometimes called “boring”). Power and torque in the high or low speed zone can be “raised” by replacing the standard camshaft with a tuning one, with modified characteristics, “high” or “low”, respectively.
There are many camshafts with modified characteristics. So which improvement method should you choose? As an example, let’s take a standard VAZ engine, on the basis of which the tuning engine is built.
Boosting a small engine
On an engine with a small volume (1300 cm3-1500 cm3) get good acceleration dynamics without crazy engine spin up to 6000-9000 rpm. It's simply impossible. You can assemble, for example, an engine with a volume of 1600 cm3 (crankshaft with a stroke of 74.8 mm, piston 82.
4mm), and set the camshaft “low” with a slight lift of the valves, while “getting ahead” of the camshaft gear by 2-4 degrees. In this case, the engine will “pull” well from low speeds. On a 1700 cm3 engine (crankshaft with a stroke of 78 mm, piston 82.4 mm), you can install a camshaft with valve lifts starting from 10.93 mm and higher.
This engine configuration is considered the most successful. The engine has good torque throughout the entire rev range and spins well up to 8000 rpm.
Boosting the “medium” engine
The 1800cc engine (crankshaft with 80mm stroke, 84mm piston) is more suitable for fans of extreme driving or people who don’t mind throwing their cylinder block in the trash in the near future. With such a displacement, the torque allows you to “switch” to higher gears even at low speeds.
You can easily install a camshaft with a valve lift of 12 mm.
The idle speed will certainly not be stable, but tolerable. On average, you need to set 1000-1100 rpm, the engine holds them perfectly. But the service life of such an engine, unfortunately, leaves much to be desired. There have been cases when, at high speeds, crankshafts with such strokes broke in half.
Refinement of the cylinder head plays a very significant, if not the main, role in preparing the engine. A properly modified cylinder head provides an increase in engine power of up to 20-30%. (the filling of the cylinders with the fuel-air mixture, the combustion of the mixture and the removal of exhaust gases are significantly improved).
You can install a zero-resistance air filter, a separate exhaust manifold (“spider” 4-2-1) and a direct-flow exhaust system, which will reduce losses during the intake and exhaust stages.
In general, tuning the intake and exhaust systems is quite expensive, and the increase in power is insignificant.
But, provided that the cylinder head is properly modified, the car acquires a noble, “thoroughbred” voice.
And if you are just a beginning fan of street racing and you are not yet sure that you are ready to spend money on capital expenditures on engine tuning , or you are simply not satisfied with the dynamics of the car?
Increasing engine power with additives
There is a simpler and more economical option for power tuning of a car engine - “restoring power tuning” . The essence is to treat the engine and transmission components with “EDIAL” friction modifiers. Our products allow you to increase the power and throttle response of the engine and transmission components.
You will definitely feel the result, especially if the car already has a high mileage and the “agility” of your iron friend has noticeably decreased. At the same time, there is no need to perform many labor-intensive operations, which significantly affects the price. Such power tuning is available to any car owner and can be done on your own.
You won't get dozens of additional horses under the hood, but a 3-5% increase in power is quite achievable.
The principle of operation of the EDIAL friction modifier for engines is well known: thanks to the special properties of the composition, the worn surfaces of friction pairs are restored to optimal sizes, and such precision of matching surfaces cannot be achieved by mechanical processing. The new working layer obtained as a result of processing is resistant to corrosion and has a low coefficient of friction.
The use of the drug allows you to eliminate engine wear and clean it of carbon deposits. And due to the properties of the formed layer on the surfaces of the friction pairs, the engine power significantly increases.
This previously expended power to overcome friction turns into useful power.
An additional advantage of this drug is engine protection when operating at high speeds, which has a positive effect on its durability.
Of course, this is not enough to become a seasoned street racer, but pleasure from the increased acceleration dynamics and an increase in the maximum speed threshold is guaranteed for almost all users of EDIAL auto chemicals.
In addition, the use of the drug does not require additional investments in fine-tuning the suspension and braking system. For true fans of street racing, the use of protective and restorative drugs is not enough.
But for those who like safe dynamic driving, this is what they need.
Enjoyment from increased acceleration dynamics and an increase in the maximum speed threshold is guaranteed for all users of the EDIAL friction modifier. Changes are especially noticeable when treating small engines, because they work at the limit of their power capabilities and the change in engine dynamics is clearly felt.
Effect of fuel on engine power
It is important to use high-quality fuel to ensure its combustion in the chamber. For this purpose, racing drivers use sports gasoline with a high octane number (more than 100 units). Basically, such gasoline is obtained from regular gasoline with the addition of alcohol additives, during the combustion of which the combustion chamber quickly “overgrows” with carbon deposits.
There is a pretty good alternative - the use of ACTIVE FUEL SYSTEM WASHING EDIAL for a gasoline engine. The use of this additive provides additional engine power (from 3 to 5%).
This is achieved by increasing the completeness of gasoline combustion and changing the combustion mode of the fuel mixture. Those hydrocarbons that were previously emitted by the engine into the atmosphere or burned by a catalyst are burned in the engine cylinders, giving it additional power and fuel economy.
This combustion process also keeps the combustion chamber, injectors, valves and the entire exhaust tract clean.

Increasing the power of a car engine with your own hands
Every car owner sooner or later thinks about increasing the engine power of his iron horse. Some people are interested in tuning and would like to become the owner of a powerful and original car, while others need to increase engine power due to a lack of power from a small engine.
Today, there are various options for increasing the power of the power unit. In this article we will tell you how to increase engine power.
What does increasing power give us?
First of all, I would like to understand what power is and what indicators are affected by engine torque.
Many car owners mistakenly believe that power is the most important indicator, since it directly affects the dynamics of the car, that is, its acceleration speed. However, most experts agree that horsepower has a greater influence on the maximum speed and acceleration rate when the vehicle is loaded.
But it is the engine torque that is responsible for the car’s dynamics and acceleration speed. Therefore, when increasing the power of the power unit, you need to simultaneously improve the horsepower and engine torque.
There are many different ways to increase the power of a car. All of them can be divided into:
- installation of additional sports spare parts;
- deep engineering tuning.
We will tell you in more detail how to increase engine power without reducing the reliability of the power unit.
Popular types of tuning
- Installation of an upgraded exhaust system
By using a forward flow or sports exhaust option, you can get about 10-30 additional horsepower, depending on the specific engine modification.
One of the advantages of installing a modernized exhaust system is not only the simplicity of the work, but also the complete preservation of engine life.
You just need to choose the right exhaust option and carry out all the repair work correctly.
This is another popular way to increase power and involves using a new engine control unit. Installing a chip allows you to increase engine power by reprogramming the operation of the power unit, which in turn, depending on the specific tuning program, allows you to get a 10-20 percent increase in horsepower.
Chip tuning is simple and has an affordable price. At the same time, it is necessary to correctly calculate the increased torque figures. Remember that such a large increase in dynamic performance can lead to a significant decrease in reliability.
- Installing turbocharging on a naturally aspirated engine
This method is a rather expensive and technically complex type of tuning, which allows you to obtain a noticeable increase in the traction and dynamic characteristics of the engine.
In this case, the car owner or the repairman must select the correct type of supercharger, calculate the engine power, determine the turbine pressure, determine the degree of engine boost, modify the intake and exhaust manifolds and reprogram the engine control program. The use of turbines that are small in terms of pressure and proper engine overhaul will increase the engine power with virtually no loss of its service life.
However, many car owners are chasing the maximum possible increase in horsepower.
It is not surprising that engines, which were originally designed for 200-250 horsepower, quickly break down and require major repairs after installing turbocharging, which increases this figure to 400 horsepower or more.
Therefore, if you decide on such a rather complex type of tuning, you need to calculate the desired power of the power unit, and based on the obtained figures, select the spare parts used.
A radical way to increase the power of a car engine can be to replace the engine with a more powerful modification. If the design of a particular car allows you to install a more powerful engine in the engine compartment, then it is much easier to do this work than to try to squeeze additional horses out of the base engine.
At the same time, the car owner must understand that in this case it will be impossible to limit himself to just replacing the engine. It is quite possible that you will have to change the CV joint, exhaust system, suspension elements and reconfigure the gear ratios in the gearbox. All this invariably complicates the replacement of the power unit.
Engineering tuning involves deep modification of the power unit, which allows you to obtain a significant increase in power without significantly reducing the service life of the engine. In this case, it is necessary to open the engine and replace the turbine (if there is one), throttle valve, camshaft, valve group, crankshaft, pistons and much more.
As you can understand, such an increase in the power of a car engine will have a fairly high cost, and all work must be performed exclusively by a professional specialist who can correctly calculate the power of the upgraded engine. This is the only way you can guarantee an improvement in the dynamic performance of the car and preserve the operational life of the power unit.
Currently on sale you can find ready-made tuning kits that are designed for a specific engine and allow you to obtain the necessary increase in power. The use of such ready-made kits allows you to increase engine power, simplifies the performance of these works and increases engine reliability.
Modifying the air intake system will allow you to gain up to 10 additional horsepower. In this case, you can get by with installing a zero-resistance air filter or completely replacing the existing standard intake system.
In the first case, the work is not difficult, which allows you to do it yourself. If you completely change the intake system, then in this case you need to use tuning kits that are suitable for a specific car.
- Using sports spark plugs will not only allow you to gain a few extra horsepower, but will also improve the performance of the power unit as a whole.
- We can also recommend that you use upgraded sport coils and high quality high voltage wires, which will also allow you to get a slight increase in power. You can do all this work yourself, without resorting to the services of professionals.

How can you increase engine power?
A great topic to consider. Probably, many car owners have thought about how to increase the engine power of their car. In light of the latest tax laws, the following situation is interesting. Imagine that you bought a new or used car with an engine power of up to 200 hp. inclusive.
Normal (ordinary, standard) power tax is provided. But the vein of envy (toad) chokes and gnaws so much that it’s hard to breathe - you want a more powerful engine, capable of literally snatching your car out of the general flow. Then, as they say, the flag is in your hands, that is, a wrench and a few more tools and forward to increasing power.
There are not many or few ways to tune an engine, but just right. Moreover, the power can be increased on both gasoline and diesel power units.
However, it should be noted that this is mainly a man's game, because for a woman it is much more important to have external beauty and internal comfort than to strengthen the engine and increase fuel consumption, which accompanies such assault in most cases.
We will look at seven main ways to help “pump up” a car engine, like the muscles of a huge bodybuilder.
Option one, the simplest, ineffective
This method supposedly “increases” engine power, but in fact it just changes the ratio of the car’s weight to the capabilities of its power unit.
In this case, standard spare parts are replaced with lighter ones, reducing the total weight, which leads to a slight increase in speed dynamics.
The main thing here is not to overdo it and not to make mistakes - not to buy any defective parts and not to reduce the weight of the car so much that it tries to take off during acceleration, despite the downforce of the spoilers.
Option two, for savvy mechanics
Probably, many people have heard of such a concept as cylinder boring, which increases the engine displacement. In this case, get ready for a significant increase in the engine's appetite. As the internal combustion chambers become larger, the engine also needs more fuel. In general, with cylinder boring, you can and even should think about purchasing and installing an additional fuel tank.
Option three, nanotechnological (just kidding)
When you think about how to increase engine power, you immediately want to do it reliably, economically and efficiently.
Well, really, why the hell bother with stupid things like lightening a car or using the old method of boring cylinder heads and cylinders, when it makes sense in our advanced age to use more advanced parts from more modern materials.
In this case, you will have to go to good mechanics, and at the same time purchase forged pistons, which are capable of being subjected to higher temperatures and loads than those installed at the factory by the car manufacturer. However, after replacing the pistons, you will have to tinker with the brakes and transmission.
Option four, for hackers and electronics engineers
Modern cars are entirely computerized and each has its own “brains,” so to speak, which can, and in our case, need to be properly adjusted. This type of power increase is called chip tuning.
It is done exclusively in a service center, by competent craftsmen and with good equipment.
In the case of chipping, the engine control unit is completely reprogrammed, which makes it possible to achieve new capabilities specifically limited by the manufacturer.
Option five, the most “smelly” (also a joke)
In this case, a direct-flow muffler is installed, which will no longer actively resist the emission of exhaust gases and will slightly increase engine power.
Roughly speaking, your car will “breathe deeply,” which cannot be said about the lungs of the people around you and their hearing abilities. The fact is that you have probably seen and heard such a muffler more than once.
It works as if it had burned out - with a deafening roar and crash. However, the horsepower will increase by 10-15, which you might be happy about.
Option six, rather sporty
Have you seen the Fast and the Furious films? Well, at least one of the parts, for sure. That’s where they installed a certain accelerator on already quite powerful cars. It looks as if the athlete was given an injection of some kind of drug, after which he suddenly briefly feels a surge of strength.
Since a car has internal combustion engines, it is logical to assume that combustion itself is possible in the presence of oxygen. When installing equipment with nitrous oxide, oxygen becomes twice as much, which dramatically increases the speed and volume of combustion.
The disadvantage of this system is its high cost, complexity of installation and short duration of use.
Option seven, the most common today
This option involves installing a turbine that produces an increased supply of air, forcing it into the working cylinders of the engine. In general, turbocharging is one of the most effective and efficient ways to increase power today.
Diesel engines
Increasing the power of diesel engines today is not as easy and simple as with a gasoline analogue. But something can be done. Specifically, you can increase the power of a diesel engine using so-called boxes. There are 4 types of these modules:
- box for changing injector control pulses;
- module for optimizing the operating modes of the ECU central processor;
- box for replacing fuel injection pump operating modes;
- box for changing the readings of the fuel accumulator pressure sensor “fuel rail”.
The first one changes, as the name implies, controls the fuel injectors, which allows increasing fuel injection. The second redistributes the fuel injection time, interfering with the injector system, allowing the latter to think.
The third is suitable only for those engines that were produced before 2008 or their modern analogues. But in this case, the power increases without reducing the service life of the engine. The fourth option is quite complicated.
In order to change the action of the pressure sensor, you will have to intervene in the entire electronic system.
Based on this information, you can conclude that you simply cannot do without good specialists, high-quality equipment and tools. And, of course, just think about why you need the increased power.

How to increase engine power: basic methods
Often, the question of significantly increasing engine power is asked in cases where the car is planned to be used for special tasks (professional motorsport, off-roading, street racing, drag racing and other areas).
Another group is car enthusiasts, for whom increasing engine power is a mandatory part of complex work on deep tuning and styling of an existing basic version of a car to create an exclusive one.
As for ordinary car enthusiasts, the desire to add power to a simple car is dictated by the banal desire to improve the accelerating dynamics of the car.
The fact is that a more powerful internal combustion engine can (sometimes significantly) increase comfort while driving, especially when overtaking and driving through uncontrolled intersections.
As practice shows, owners of small and medium-volume naturally aspirated gasoline engines most often seek to increase engine power. Less often, an initially turbocharged gasoline engine is subjected to global alterations, and only in some cases the power of a diesel engine is increased.
Next, we will look at the main methods that allow you to increase engine power to a greater or lesser extent.
Read in this article
So, let's go. The list of popular solutions for increasing engine power includes:
Let us add that we will not talk about such exotic solutions as nitrous oxide systems NOS or “nitro” (from English Nitrous Oxide System). Such solutions are installed on specially prepared racing cars and are not a way to permanently increase the power of the internal combustion engine, as they produce a temporary effect.
What does water injection into an engine provide, the principle of operation, the main advantages and disadvantages. How to inject water into the engine yourself, available methods.
Now let’s take a closer look at the above methods of modifying the motor. Let's start with the difficult one. Replacing the crankshaft and boring engine cylinders, preparing the cylinder head, as well as replacing pistons, connecting rods and camshafts is the so-called “iron” tuning.
The method makes it possible to reduce losses during operation of the internal combustion engine, increase efficiency, increase the physical volume of the engine, increase the compression ratio, improve the filling of the cylinders and influence the efficiency of gas distribution at different engine operating modes.
This approach can be implemented either partially (only individual nodes are changed) or comprehensively.
Let us add that on many cars it will not be possible to bore the block too much, since the walls of the cylinder block are quite thin and are designed to be bored to 3 repair sizes.
Note that this procedure is quite expensive and requires additional modifications to the power system in the case of injection engines and a number of other changes to the standard design.
During operation, such an engine requires increased attention, refueling with high-octane quality fuel and expensive motor oil. At the same time, fuel consumption increases.
Engines after such tuning are very afraid of detonation and often have a short resource.
An equally complex way to increase engine power is to install a turbocharger on a naturally aspirated engine. Note that this approach is more effective compared to the modifications to the atmospheric internal combustion engine described above. Moreover, in combination with replacing engine components with reinforced parts (as in the first method), it becomes possible to obtain very impressive results.
The disadvantages include the need for careful selection of spare parts, the need to fine-tune the motor and resolve complex technical issues. Not every specialist will undertake such work.
Budget ways to increase power: intake, exhaust, chip tuning
It is quite obvious that such improvements are carried out as part of preparing the car for sports competitions or to create individual projects. Ordinary car enthusiasts don't need this. For this reason, simple and cheap ways to increase the power of a power unit are very popular.
These include installing a zero-resistance air filter (nulevik), which has less intake resistance and allows the engine to receive more air.
The increase in power is minimal (especially on an atmospheric engine) or not noticeable at all (from 0.5 -2.5%), but the solution itself is available to every car owner.
Note that many drivers are skeptical about this method, since the big disadvantage is the poor filtration of the air that enters the engine and pollutes the power unit.
A more noticeable effect is achieved by tuning the exhaust (removing the catalyst, installing an exhaust with pipes of changed diameter, installing a direct-flow muffler). The main task is to reduce the resistance that is created when exhaust gases are released. These gases move more optimally in the modified exhaust system.
In this case, the engine picks up speed better, and the acceleration dynamics become more intense. On some cars, after professional selection of pipe diameters and proper installation, the power increase can be up to 5%.
The method will require certain financial costs, but it still remains much cheaper compared to modifying the internal combustion engine or installing a turbine on the engine.
The advantages include a programmatic increase in power and torque, improved engine response to pressing the gas pedal, and a reduction in turbo lag on turbocharged units. In other words, there is no need to change any units and components.
After high-quality firmware, the engine runs more stable at idle, there is no drop in power after turning on powerful consumers (air conditioning, heated seats, mirrors, etc.). The disadvantages are considered to be increased demands on the quality and octane (gasoline)/cetane (diesel) number of fuel, as well as a decrease in engine life.
It should also be taken into account that unprofessional ECU firmware can cause serious malfunctions in the operation of the motor or failure of the control unit itself.
