Turbocharging is the single most popular method for adding brute power to an engine, but this video shows the manufacturing of a turbocharger is anything but brutal. Instead, the process combines precision machining with ancient methods of metal shaping.
The manufacturing process inside the Turbonetics factory starts with molten aluminum being poured to form the sandcast housings and progresses through exacting CNC processes and unhurried assembly. The human touch is the most notable part of the process: The making of these devices, which spin at 100,000 RPM and help hurl two-ton machines past 200mph, depends largely on the skilled hands of the company's technicians.
