A turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, increasing pumping losses. [ 53 ] Supercharged engines are common in applications where throttle response is a key concern, and supercharged engines are less likely to heat soak the intake air.
Front-mounted air-to-air intercooler Top-mounted air-to-liquid intercooler (the silver cuboid-shaped part) on a BMW S55 turbocharged engine. An intercooler is a heat exchanger used to cool a gas after compression. [1] Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas ...
Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change. This is done with the use of adjustable vanes located inside the turbine housing between the ...
exhaust system Cast iron exhaust manifold (with integrated BorgWarner turbocharger), one primary and one main ceramic catalytic converters, two heated oxygen sensors monitoring pre- and post catalyst exhaust gases dimensions length: 652 mm (25.7 in), width: 648 mm (25.5 in), height: 666 mm (26.2 in), mass: 152 kg (335 lb)
A turbocharger for a car engine A supercharger (on top of a dark-grey inlet manifold) for a car engine. In an internal combustion engine, forced induction is where turbocharging or supercharging is used to increase the density of the intake air. Engines without forced induction are classified as naturally aspirated. [1]
Compression ratio for the turbo engine falls to 10.6:1 from 12.5:1 for the FA20D. A revised variant of the FA20F was introduced for the 2015 model year Subaru WRX; in this application, the camshafts, rocker arms, boost pressure, intercooler, and exhaust were revised to increase peak output. [4]

Therefore, sequential turbocharger systems provide a way to decrease turbo lag without compromising power output at high RPM. [4] The system is arranged so that a small ("primary") turbocharger is active while the engine is operating at low RPM, which reduces the boost threshold (RPM at which effective boost is provided) and turbo lag.
