Having mounted the compressor on the VAZ, it is possible to increase the motor power quite effectively. Due to the fact that the air supply to the fuel system is increased, the charge of the fuel-air mass entering the cylinder is increased. However, the installation of the compressor also has negative sides. In particular, fuel consumption increases .
To fix the compressor on the engine, you will need the kit itself, a set of keys, an abrasive paste, a sensor to control boost pressure, an air filter with reduced resistance.
The increase in power occurs due to an increase in air concentration in the fuel system.
Proceed with installation after the cooling of the power unit of the car. After that, it is necessary to dismantle the air duct, as well as the standard air filter. Next, unscrew the bolts that secure the collector to the exhaust pipe and carefully polish the pipes. Their surface should be perfectly smooth. The T-shaped bracket for the tension rollers and the motor block are mounted with the compressor mounting bracket. Pump and generator drive belts should be removed as unnecessary in the future. Instead, they use a special belt. They are equipped with a compressor at the VAZ. The belt must be tightened well, however, it is not worth overdoing it. A slight slack should remain. Otherwise, increased wear of the part is likely, which will lead to its rupture. It should be said that this element is very difficult to find separately from the kit. It should also be noted that the belt, loose, will sag and slip on the pulley. This, respectively, will lead to a drop in power (or just a slight increase) and adversely affect the condition of the cooling system. The optimal deflection of the belt is half a centimeter when pressed with a finger.
After adjusting the belt tension, the intake spider should be installed back. The air duct is mounted back from the outlet in the “cochlea” to the inlet in the injector. It is recommended to avoid too sharp bends in the corrugated elements. In addition, the contact of the duct with very hot parts of the motor should be excluded. The compressor on the VAZ should also be equipped with a measuring device for the boost pressure control sensor.
Next, attach a low resistance filter. The compressor on the VAZ has an inlet pipe. The filter should be attached to it. It should be located in the coldest part of the engine compartment. When compressed, air is heated, it also becomes more discharged. The lower, thus, the temperature at the inlet, the ultimately it will get into the motor more. Due to this, the air-fuel charge will increase in its mass, and, accordingly, the power of the vehicle’s power unit.
After installing the compressor, the injector should be adjusted in accordance with the changing air supply conditions. This is necessary so that a “rich” mixture enters the engine. As a rule, tuning is not done on their own. There are specialized services for this.
And on the dashboard it is necessary to fix the charge pressure control sensor. He will warn about probable problems, and will contribute to an economical ride.
After tuning the car you need to take care of the body. It is recommended to paste over with an anti-gravel film. After the compressor is mounted, the air resistance should be set to a minimum. It should be said once again that all work must be done after the engine has completely cooled.
