For example, an ordinary 2.0 engine can produce 110-147kw of power. If a turbocharger is installed, 220KW of power can be generated. This is definitely not false data, it is actually measured by us, that is to say, after modifying the turbocharger, it will definitely increase the power by 30%-50% compared to before.

In terms of increasing the power of a car engine alone, modifying turbocharging is the best way, but more conservative settings are usually used in terms of turbo capacity, boost value or A/R value. Many people still have a lot of confusion about the modification of turbocharging. Should we choose a turbocharger that can exert high power or a torque turbocharger that can be used at a low speed?

Different engines have their own characteristics. When choosing a turbine, the design of the engine should also be considered. In addition, the consideration of displacement is also very necessary. For example, a large-displacement engine is equipped with a torque-type small-capacity turbocharger. When the car reacts well at low revolutions, the turbocharger can exert a fast effect, but when the capacity is full, The speed has reached the limit in a blink of an eye, and the pressure is difficult to increase at this time. Therefore, in the high-speed area where the exhaust gas energy is large, the supercharging has reached the limit, and the car cannot further increase the intake of the engine, at this time, it is difficult to increase the power as the engine speed increases. This is the disadvantage of small turbines.

Refitting the turbocharger, because it will increase the resistance and cause the pressure in the exhaust pipe to rise, so the first step of the modification is to modify the exhaust. You only need to replace the exhaust FrontPipe (turbine exhaust front section pipe) connected to the Turbine outlet. It is installed with a large diameter to reduce the secondary back pressure. At the same time, the pipe diameter of the middle and tail sections must be thickened, and the structure is linearized and gradually enlarged, so the supercharging rate will increase.

Then there is the branch pipe linking the growth to the inlet of the exhaust turbine. This method can make the exhaust gas in each cylinder have the same rhythm, which can improve the efficiency of supercharging and also increase the life of the turbocharger. But there are also some disadvantages, which will reduce the low-speed torque.

It should also be noted that for the supercharging modification of the engine, it is definitely not a simple price turbocharger. Many corresponding peripheral configurations must be strengthened and modified at the same time.

The gasoline pressure valve is the first item to be modified. After turbocharging, the air flow and rate will increase, so the gasoline pressure must also increase.

In terms of exhaust, we also mentioned above that it is best to use a double-port exhaust pipe, which can provide a greater flow of exhaust.

At the same time, the intercooling system should also be improved, because the use of turbocharging will generate high heat, and good heat dissipation is necessary.
