Many drivers would like to increase the power of the car engine. Why?
Well, so more confidence, for example, when overtaking, you can maneuver more sharply and brazenly in the city. And additional horses under the hood just warms up the soul. But power increase almost always means that the appetite of the engine will also grow. And it is not desirable at all. Is there any way to increase engine power – reliable, effective and preferably not entailing constant additional expenses?
How to increase engine power: 6 ways
- To increase the compression ratio
This can be done by reducing the height of the lower plane of the cylinder head with the help of milling or by installing pistons with a more convex upper part.
You can also put a modified camshaft – the valves will close with a delay, and the compression ratio will be higher. With this modification, the efficiency and power of the engine increases. Another pleasant bonus – fuel consumption is slightly reduced. But it is necessary to use gasoline with a higher octane number, because the risk of detonation increases because of the camshaft.

- Install the flare
The power increases due to the fact that the resistance of exhaust gases is significantly reduced, the engine accelerates faster. The disadvantages are known to all – a roaring sound, for a very rare amateur. Besides, the straight-throttle system should be of high quality, otherwise there will be no effect, except for a terrible roar.
- Install a turbine on an atmospheric engine
Yes, it will not affect the flow rate, but the turbine itself and the installation are not cheap, the process is technically complex. So choose your master carefully. The turbine enriches the fuel-air mixture with oxygen, the compression and explosion force increases and, accordingly, the power. Adds up to 5% power.
- A “zero resistance” air filter
Gives a power gain of only 1-3%, but this method is one of the cheapest. Such a filter reduces the resistance to fuel movement in the intake and increases the supply of oxygen-air mixture.
- Minimum mechanical losses
For this purpose, light forged parts are installed instead of the standard parts. These parts are not cheap, and the increase in power is minimal.
- Installing a larger diameter exhaust pipe – due to the fact that the exhaust gases move more freely.
Chip tuning of the engine: a real increase in power
“Real” in the matter of increasing the power of the motor is by 5-20%. The maximum possible increase is up to 50% in turbocharged engines. But in order to significantly add power, you will have to sacrifice ecology and resource – disable the particulate filter function.
Chipping, i.e. software correction of technical parameters, is possible for any engine with ECU, either atmospheric or turbocharged. TSI engines from Volkswagen and turbo diesel engines from Volvo are good for tuning. At the same time the iron – units and mechanisms – are not modified in any way.

Chip tuning in most cases is not a show-off, but an opportunity to unlock the car’s full potential. After all, car manufacturers are limited by legislation, environmental requirements and often software “stifle” the capabilities of engines. Well, in some cases, car manufacturers specially reduce the power of engines of the same volume – to expand the model range.
Chip tuning has become surrounded by a lot of myths, but nevertheless it has its advantages and remains the most effective way to increase capacity. The main thing is to choose a good specialist.
The advantages of engine chip tuning:
– Increased power. For atmospheric engines by 8-15%, for turbocharged engines a gain up to 50% is possible. The power increase is reached due to the fine tuning of the injection system and the turbine. Master adjusts power individually, taking into account driving style and needs of the client, finds optimal ratio of consumption and power.
– The torque increases at low revs, the turbo lag disappears on an engine with a turbine. In general, the engine runs more smoothly and smoothly.
– Gas pedal becomes more responsive.
– You can also remove the errors, which are not taken care of at official services: lambda probe error, particulate filter, box error.
– You can adapt your engine to fuel with a lower octane number.
– There is an opinion, that the proper tuning of the internal combustion engine reduces consumption. But, who is cheating an engine to save money? And turbocharged motors are economical only until the turbo is running.
Of course, there are disadvantages of chip tuning, because it is an intervention in the “brain” of the engine. Therefore it is very important to carefully choose the tuning workshop.
Masters must work on special equipment, use professional software (its own or from leading manufacturers). After tuning you must be given a flash drive with a previous version of the firmware, so you have the opportunity to “rollback” at any time. Remember, a good tuning shop gives an unlimited warranty on their work and software.
