det er om det er seqeuntial eller parallel der betyder noget størrelsesmæssigt på de to ladere...

Parallel twin-turbo refers to a turbocharger configuration in which two identical turbochargers equally split the turbocharging duties with both turbos functioning simultaneously. Each turbocharger is driven by one half of the engine's spent exhaust energy. In most applications, the compressed air from both turbos is combined in a common intake manifold, and sent to the individual cylinders. Commonly each turbocharger is mounted to its own individual exhaust/turbo manifold, however on inline-type engines both turbochargers could be mounted to a single turbo manifold. Parallel twin turbos applied to V-shaped engines are usually mounted with one turbo assigned to each cylinder bank, providing packaging symmetry, and simplifying plumbing over a single turbo setup. When used on inline engines the parallel twin turbos are commonly applied with two smaller turbos, which can provide similar performance with less turbo lag than a single larger turbo. Some examples of parallel twin-turbo inline engines are Nissan's RB26DETT, BMW's N54 and Volvo's B6284T and B6294T. Some examples of V formation engines with parallel twin-turbos include Mitsubishi's 6G72TT, Nissan's VG30DETT. Audi's 1997-2002 S4 (B5), 1997-2005 A6, and 2003-2004 RS6.
While a parallel twin-turbo set-up theoretically has less turbo lag than a single turbocharger set up, this is not always the case due to many factors, including, marginally-reduced combined inertial resistance, and often simplified exhaust plumbing and the fact that both turbos spool at more or less the same time means that there can still be a noticeable bit of lag, especially in high-flow turbo/high boost applications. Some ways to counter this are to use a light pressure set up with smaller turbos, where the turbos are designed to output less boost but spool earlier. This set up does sacrifice some top end power however it has less lag than a similar engine with a single turbo set up making the same power. Another system would be the use of variable geometry turbochargers, this system changes the angle of the guide vanes depending on the exhaust pressure giving the system excellent power throughout the rev range. Once used mainly in turbocharged diesel engines, Chrysler was the first to use it in mass-production gasoline-powered vehicles with the Shelby CSX, debuted in 1989.
It is possible to use parallel operation of more than two turbochargers, such as the Bugatti EB110 and Bugatti Veyron; both of which run four turbochargers in parallel. The EB110 runs 4 turbos on a 3.5 litre V12 engine, producing 542 hp (404 kW) at 8000 rpm. In the Veyron's case, it is a 16 cylinder engine that generates 1,001 PS (736 kW; 987 hp).
[edit] Sequential twin-turbo
Sequential twin-turbo refers to a set up in which the motor utilizes one turbocharger for lower engine speeds, and a second or both turbochargers at higher engine speeds. During low to mid engine speeds, when available spent exhaust energy is minimal, only one relatively small turbocharger, the primary turbocharger, is active. During this period, all of the engine's exhaust energy is directed to the primary turbocharger only, lowering the boost threshold, minimizing turbo lag, increasing power output at low engine speeds and providing the benefits of a small turbo. Towards the end of this cycle, the secondary turbocharger is partially activated (both compressor and turbine flow) in order to pre-spool the secondary turbocharger prior to its full utilization. Once a preset engine speed or boost pressure is attained, valves controlling compressor and turbine flow through the secondary turbocharger are opened completely (the primary turbocharger is deactivated at this point in some applications). At this point the engine is functioning in a full twin-turbocharger form, providing the benefits associated with a large turbo, including maximum power output, without the disadvantages such as increased turbo lag.
Sequential twin-turbocharger systems provide a way to decrease turbo lag without compromising ultimate boost output and engine power. Examples of cars with a sequential twin-turbo setup include the 1986-1988 Porsche 959, the 1992-2002 Mazda RX-7 Turbo (FD3S), the 1993-1998 Toyota Supra Turbo (JZA8x), and the 1994-2005 JDM Subaru Legacy GT, GT-B, RS, RS-B & B4. With recent advancements in turbocharger design, and reductions in lag this has made possible, sequential twin turbo systems have fallen out of favor because they are seen as unnecessarily costly and complex.
Sequential twin turbo can also refer to a system where the output pressure must be much greater than atmospheric. In this case, two similarly sized turbochargers are used in sequence but with both operating all of the time. In this case the first turbo boosts pressure as much as it can (for example to three times the intake pressure) then the second turbo takes this charge and increases it further (for example to an additional three times intake pressure, for a total boost of nine times atmospheric pressure) to a pressure not possible by a single turbo. This is commonly found on piston engine aircraft which usually do not need to rapidly raise and lower engine speed (therefore turbo lag, while still present is not a problem) and where the intake pressure is quite low due to low atmospheric pressure at altitude, requiring a very high pressure ratio. High-performance diesel engines also sometimes use this configuration, since diesel engines do not suffer from pre-ignition issues and can use significantly higher boost pressure than Otto cycle engines.

om det er to forskellige størrelser eller de er ens er ligegyldigt hvad navnet angår

BMW 535d (den nyeste) er også iflg. BMW en TwinTurbo, det er 2 i sekventiel.
BMW 335i (den nyeste) kalder de bi-turbo, og her er det også 2 i sekventiel..
Brabus SV12 S Biturbo.. igen.. her er der tale om 2 ens i parallel..
Der er INGEN regel for Twin eller Bi.. de betyder begge 2.
Der hvor forskellen ligger er om det er parallel eller sekventiel...

Det er bare 2 turboer der kan arbejde samtidig eller hver for sig, alt efter opbygning.
har du f.eks. en V6 sidder der en turbo til tre cylindere. udstødningsgassen driver så de to turboer.
