What are the advantages of turbocharger?
To improve engine power. In the case of constant engine displacement charge density can be increased, so that the engine can be more fuel injection, thereby increasing engine power, after installation of the booster engine power and torque to be increased by 20% to 30%. On the contrary, at the request of the same power output can reduce engine bore and narrow engine size and weight.

What is the role of the journal bearing on turbocharger?
The journal bearing system in a turbo functions very similarly to the rod or crank bearings in an engine. These bearings require enough oil pressure to keep the components separated by a hydrodynamic film. If the oil pressure is too low, the metal components will come in contact causing premature wear and ultimately failure. If the oil pressure is too high, leakage may occur from the turbocharger seals.

What are the disadvantages of using stamped strip for Thrust Bearings?
Stamped Strip – Involves stamping the initial blanks out of a strip of brass material and is used for smaller thrust bearings. This method limits the strength of the material as this has to be weighed against the life of the stamping tool; an increase in strength in the material causes a massive reduction in tool life.
