Turbo Maintenance



A turbocharger is a small fan pump that spins around a shaft. The pump is driven by the pressure of the exhaust gas. A turbocharger consists of a turbine and a compressor. They are both mounted on the same shaft. The turbine is a heat engine. It converts exhaust heat and pressure to rotation. This rotation is used to turn the compressor.

The compressor takes in the draws in the outside air. It squeezes or compresses the air. It then sends the air to the engine. Because the air pressure has been increased, more air and fuel may be put into the cylinders. This is sometimes called boost pressure. With more fuel to burn, the engine can create more power. This increases the horsepower of the engine.

Turbo Maintenance

Turbochargers can be damaged by dirty or poor oil. Most manufacturers recommend more frequent oil changes for turbocharged engines. The turbocharger will heat when running. Many recommend letting the engine idle for several minutes before shutting the engine off.

This gives the turbo time to cool down and will increase the life of the turbo.

Turbo lag

The time required for the turbo to build up the needed pressure is called turbo lag. This is noticed as a hesitation in engine response. This is caused by the time taken for the exhaust system to speed up the turbine. The directly-driven compressor in a supercharger does not have from this problem. Lag can be reduced by using lighter parts. This allows the turbine to start faster. Other mechanical changes can reduce turbo lag, but at an increase in cost.
