Twin-turbo
Twin-turbo is a type of turbo 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 independent piping. The two turbochargers can either be matching or different sizes.
There are three types of turbine setups used for twin-turbo setups:
These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups):
In a parallel configuration, two equally-sized turbochargers each receive half of the exhaust gases. Some designs combine the intake charge from each turbocharger into a single intake manifold, while others use a separate intake manifold for each turbocharger.
Parallel configurations are well suited to V6 and V8 engines since each turbocharger can be assigned to one cylinder bank, reducing the amount of exhaust piping needed. In this case, each turbocharger is fed exhaust gases by a separate exhaust manifold. For four-cylinder engines and straight-six engines, both turbochargers can be mounted to a single exhaust manifold.
The aim of using parallel twin-turbos is to reduce turbo lag by being able to use smaller turbochargers than if a single turbocharger was used for the engine. On engines with multiple cylinder banks (e.g. V engines and flat engines) use of parallel twin-turbos can also simplify the exhaust system.
The 1981–1994 Maserati Biturbo was the first production car to use twin-turbochargers.
Sequential turbocharging is a set-up in which the engine uses one turbocharger for lower engine speeds, and a second or both turbochargers at higher engine speeds. This system is intended to overcome the limitation of large turbochargers providing insufficient boost at low RPM. On the other hand, smaller turbos are effective at low RPM (when there is less kinetic energy present in the exhaust gases) but are unable to provide the quantity of compressed intake gases required at higher RPM. Therefore, sequential turbocharger systems provide a way to decrease turbo lag without compromising power output at high RPM.
