Components:
The turbocharger has four main components. The turbine (almost always a radial turbine) and impeller/compressor wheels are each contained within their own folded conical housing. They are on the opposite sides of a center housing/hub rotating assembly (CHRA). The housings fitted around the compressor impeller and turbine collect and direct the gas flow through the wheels as they spin. Twin-scroll designs have two valve-operated exhaust gas inlets, a smaller sharper angled one for quick response and a larger less angled one for peak performance.
the amount of air or exhaust that can be flowed through the system is dictated. Details like the curvature and number of blades on the wheels, Measurements and shapes etc can vary.
The center hub rotating assembly (CHRA) houses the shaft which connects the compressor impeller and turbine. This component has a bearing system to suspend the shaft, allowing it to rotate at very high speed with minimal friction. In the case of automotive uses, CHRA typically uses a thrust bearing or ball bearing lubricated by pressurised engine oil.
