A mechanically driven supercharger offers exceptional response and low-rpm performance, as it does not rely on pressurization of the exhaust manifold (assuming that it is a positive-displacement design, such as a Roots-type or twin-screw, as opposed to a centrifugal supercharger, which does not provide substantial boost in the lower rpm range), but is less efficient than a turbocharger due to ...
In an internal combustion engine, twin-turbo is a layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine 's produced exhaust through ...
A twin-scroll turbocharger uses two separate exhaust gas inlets, to make use of the pulses in the flow of the exhaust gasses from each cylinder. [34] In a standard (single-scroll) turbocharger, the exhaust gas from all cylinders is combined and enters the turbocharger via a single intake, which causes the gas pulses from each cylinder to ...
The engine uses smaller twin scroll type turbos (for reduced turbo-lag), a bespoke Bosch ECU, a modified intercooler configuration, and dry sump lubrication. It produces 730 PS (537 kW; 720 hp) at 5800 rpm [ 8 ] and 1,000 N⋅m (738 lb⋅ft) of torque at 2250-4500 rpm. [ 8 ]
Most turbocharged petrol engines use a single turbocharger; however, twin-turbo configurations are also often used. In motor racing, turbochargers were used in various forms of motorsport in the 1970s and 1980s. Since the mid-2010s, turbocharging has returned to several motor racing categories, such as Formula One and the World Rally Championship.
The BorgWarner developed turbo can produce up to 27 psi (1.9 bar) of boost thanks in part to its unique dual volute turbine housing and an electrically actuated wastegate. Instead of two side-by-side exhaust passages like on a regular twin-scroll turbocharger , in this design the two exhaust passages are concentric and allow for better use of ...

The M176/M177/M178 is a petrol V8 engine range designed by Mercedes-AMG, replacing the M278 and M157 engines, and is based on the M133 engine. [1]The engine has two BorgWarner turbochargers positioned between the two cylinder heads in a "hot-V" configuration.
