The TwinPower Turbo and the TwinTurbo Power are the two different varieties of twin turbo BMW engines. You’ll discover an exhaust manifold divided into two headers in both possibilities. One turbo unit and two exhaust down tubes make up the TwinPower Turbo. Two turbos and two exhaust down tubes are part of the TwinTurbo Power.

What distinguishes TwinPower Turbo from TwinTurbo Power fundamentally?
Based on firing order, the exhaust manifold in both designs is evenly divided into two headers. The TwinPower Turbo, often known as the dual scroll turbo, is a single turbo powered by two exhaust down tubes and two pairs of alternating cylinders. Each of the two exhaust down tubes on the Twin Turbo Power’s two turbos is fed. Refer to the illustration below to see how the TwinPower Turbo technology looks. The following example is from a 4-cylinder engine, but the same concept may be used with 6-, 8-, and 12-cylinder engines.
Now that the fundamental concept has been clarified, we can further discuss why BMW shifted to the TwinPower design and its benefits over the Twin Turbo Power design.
The BMW Twin Power Turbo is what?
The inline 6-cylinder CommonRail TwinPower Turbo diesel engine from M Performance combines variable turbine geometry, three-stage turbocharging, and CommonRail direct injection. This engine is special due to its wide rev range, tremendous torque even at low rpm, and incredibly quick response.
320d BMW engine twin turbo?
320d. The BMW TwinPower Turbo four-cylinder diesel engine from the previous generation is still used in the new BMW 3 Series Sedan, but it has been improved for even better fuel efficiency and reduced emissions with no loss in power.
The BMW 328i has twin turbos, right?
The 2.0-liter, four-cylinder TwinPower Turbo engine used in the 328i generates 240 horsepower between 5,000 and 6,000 rpm and 255 foot-pounds of torque between 1,250 and 4,800 rpm. TwinPower is BMW’s twin-scroll turbocharger system.
What distinguishes TwinPower Turbo from twin turbo?
BMW created its ground-breaking TwinPower Turbo technology on the basis of the twin-scroll principle, as alluded to in the first sentence. In essence, the name tells it all, yet even if it’s obvious, many people don’t find it to be that simple.
First off, despite the fact that both use two turbochargers, a widespread misunderstanding is that twin turbo = biturbo, which is rarely the case. Another misconception is the idea that TwinPower Turbo really refers to a twin turbo setup, which is untrue.
To further explain, let’s begin with the following definitions:
- Two turbochargers are used in tandem with each other in twin turbo technology (“twin”)
- Biturbo also uses two turbochargers, but they are divided equally on either side of the cylinder bank (typical for V8 engines)
- A single turbocharger with two scrolls is the foundation of the BMW TwinPower Turbo.
- Two turbochargers are used by BMW TwinTurbo Power (yes, this variant also exists).
- Don’t confuse TwinPower Turbo with TwinTurbo Power because they are different.
It seems simple, huh? It sort of is. An exhaust manifold that is properly constructed and what is known as a divided intake turbine are both components of BMW’s TwinPower Turbo technology. The last part is extremely important since it aids in properly aligning the cylinders so that exhaust gas can be directed independently on a single scroll.
As you may remember, the TwinPower Turbo is now installed on BMW engines with either four or six cylinders, depending on the fuel type being used (diesel or petrol). In inline-four applications, the first and third firing cylinders are paired on one scroll, while the second and fourth firing cylinders are coupled on the second scroll.
The combination order for inline-six engines is commonly 1-3-5 on one scroll and 2-4-6 on the other scroll. Given the heated inner V architecture of the BMW V8 units (the N63/S63 generation), the requirement for greater power led to the adoption of twin turbo, or two turbochargers combined (with the turbochargers placed between the cylinder banks). And indeed, despite not having a clear name, the 8-cylinder engine’s turbocharging system is known as BMW TwinTurbo Power.
Moving on to TwinPower Turbo, which utilizes the twin-scroll concept, there are a number of advantages over single-scroll turbochargers.
- due to the balanced pairing of cylinders depending on firing order, the boost response is proper and swift.
- Continual recirculation of exhaust gases via the twin-scroll engine’s exhaust system enables consistent, uninterrupted power output at all engine speeds.
- the turbocharger wheel is fed with as much pulse energy as possible.
- increased running effectiveness and turbocharging unit life
- considerable reduction in fuel use and turbo lag
- a better low-end power delivery that is comparable to twin turbo engines
- measurable progress in lowering pumping losses
Other parts have been created to improve the balance and smoothness of the engine’s operation in order to exploit the advantages of the BMW TwinPower Turbo. The centrifugal force pendulum included into the dual-mass flywheel operates to avoid any irregular engine rotations, which are prone to occur at low rpm. The vertically offset balance shafts correct the vibration optimally.
What is the horsepower of a BMW twin turbo?
The 6-cylinder Twinpower Turbo redlines at 7000 rpm and has a maximum output of 300 horsepower at 5800 rpm. At 1200 rpm, the maximum torque of 300 lb-ft almost instantly begins. Until 5000 rpm, it keeps forcing you back in your seat.
Is a twin turbo engine preferable to a single?
Twin scroll kits are less common than single turbo kits. Why? They are smaller and more economical. If you already don’t have much space under the hood, the latter quality can be really helpful. Single turbos produce more horsepower and increase boost more slowly than twin turbo setups because they have a wider power band. Due to the extra traction, a single turbo is preferable when wanting to improve the performance of a muscle car.
The operation of the BMW twin-scroll turbo.
You’ll see that the BMW TwinTurbo Power option utilizes two turbochargers. The two turbochargers are often positioned one next to the other in twin turbo technology. By forcing more air into the combustion chamber, these parts combine to increase your engine’s power and fuel efficiency.
Turbo lag exists with two turbos?
Twin turbo systems ought to have less turbo latency than a single turbo arrangement, theoretically. However, they frequently still exhibit some turbo lag. The size of the turbos being used and the pressure setting determine how much lag there is.
Is twin turbo superior to twin scroll turbo?
Compared to single-scroll turbochargers, twin-scroll turbochargers are superior in almost every manner. The exhaust pulses are split by two scrolls. For instance, cylinders 1 and 4 may feed to one turbo scroll while cylinders 2 and 3 may feed to a different scroll on a four-cylinder engine with the firing order 1-3-4-2. Why is this advantageous? As the piston reaches bottom dead center and the exhaust valve begins to open, let’s suppose that cylinder 1 is nearing the conclusion of its power stroke. However, there is some overlap as cylinder 2 completes the exhaust stroke, closes the exhaust valve, and opens the intake valve. Since both exhaust valves are briefly open in a conventional single-scroll turbo manifold, less pressure will reach the turbo and less air will be pulled in by cylinder 2, which will cause interference with the exhaust pressure from cylinder 1. In order to solve this issue, the scrolls are divided.
- The exhaust turbine receives more energy, which increases its power.
- Based on the various scroll designs, a larger RPM range of effective boost is feasible.
- There is additional tuning flexibility because higher valve overlap is allowed without impairing exhaust scavenging.
- need a certain engine configuration and exhaust design (eg: I4 and V8 where 2 cylinders can be fed to each scroll of the turbo, at even intervals).
- Compared to standard single turbos, cost and complexity.
Which turbobrand does BMW employ?
The new BMW M3 and M4 models use turbocharger technology from Mitsubishi Turbocharger and Engine Europe. At least two single scroll turbochargers are fitted to the 3-liter S58 engine in order to boost this strong engine.
BMW turbos are they reliable?
Author: Paul Stenquist
The strains that a turbocharger must endure seem like a prescription for mechanical disaster, with operational temperatures that soar to 1,500 degrees Fahrenheit and internal speeds that soar over 100,000 rpm.
And indeed, during prior spikes in turbo popularity, catastrophes occurred frequently. Consumers may be wondering whether they should be concerned about the reliability of these devices now that automobiles with turbocharged engines have increased to over 20% of new sales, according to Honeywell, a major components supplier.
The automotive turbocharger, which uses a small turbine powered by the engine’s exhaust to spin a compressor section, is merely a pump intended to force more air into an engine. Because of the technology, automakers may use smaller engines to achieve the necessary horsepower while also achieving higher fuel efficiency. Because of this, as new models are released, turbo engines are becoming more and more well-liked.
Inadequate materials and insufficient lubrication have been blamed for the turbo failures of previous decades. In either case, the malfunctions can damage a carmaker’s reputation and the repairs are expensive. Therefore, the technology-using automakers can’t afford any errors.
They made blunders in the past. Some 1980s cars’ turbos proved to be problematic. When the engine was running, the turbine bearings were lubricated, but when it was shut off, they overheated, turning the lubricating oil into deposits of hardened ash. Customers started to avoid turbos.
The influx of turbocharged vehicles suggests that the issues have been resolved, at least in part. The reliability of turbos has increased, according to Mike Katerberg, a senior powertrain engineer at General Motors, who also noted that the warranty rate for GM turbos is extremely low and that they don’t rank among the top 15 most often failing engine components. Internal parts can withstand high speeds better thanks to lubrication circuits for bearings and cooling that continues after shutdown; the turbo housings are composed of more robust alloys.
Real-world durability is still up for debate. Consumer Reports magazine, which conducts extensive owner surveys, has observed certain problems.
According to Douglas Love, a magazine spokesman, “Traditional turbos from Audi, Volkswagen, and BMW have proved reliable when they are relatively new but developed issues as they aged.” “Newer turbo engines, like the Ford EcoBoost, haven’t always proven dependable, even at first.”
Condensation-related issues with acceleration were reported by Ford owners to NHTSA, however failures of the turbo itself don’t seem to be frequent. Turbo failure issues have been reported by NHTSA for the Volkswagen Passat TDI and the BMW 535is (which uses a turbodiesel engine). Additionally, a 2015 A3 model’s turbo failure was reported in an Audi service bulletin in August.
Other problems exist besides turbo longevity. Small turbocharged engines aren’t delivering on the fuel-efficiency claims by the manufacturers, according to a Consumer Reports report from February 5, 2013.
The GM engineer Katerberg noted that the turbo will outperform the larger normally aspirated engine under light loads at constant cruise speed since it operates without boost and the benefits of reduced displacement come into play.
