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. (Hat
