Everything is in the name with BMW TwinPower 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.
Summary
Many inquiries have been made about BMW’s TwinPower Turbo, which they refer to as a dual scroll single turbo. There have even been lawsuits filed for deceptive advertising. Despite initially appearing complicated, a double scroll design really adds considerable performance advantages over a single, single scroll turbo. Separate exhaust pipes and “scrolls” are used to boost power, torque, and fuel economy while decreasing turbo lag and reversion. A twin scroll turbo is nevertheless less expensive and less potent than a genuine twin turbo setup.
TwinPower Turbo Engines by BMW
The heart of every BMW is an innovative petrol and diesel engine featuring BMW TwinPower Turbo technology. They blend cutting-edge turbocharger technology, fully variable performance control, and the newest injection technologies.
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.
Which BMW models are twin turbo V8s?
From 2008 till the present, the twin-turbocharged V8 petrol engine known as the BMW N63 has been manufactured. The N63’s “hot-vee” architecture, with the turbochargers housed inside the “V” of the engine, makes it the first production automobile engine in the world. Additionally, it is BMW’s first V8 turbocharged engine.
A naturally aspirated V8 engine, the BMW N62 was succeeded by the N63, which made its debut in the 2008 X6 xDrive50i.
What model BMW has a v6 twin turbo?
From 2006 through 2016, BMW developed the N54, a twin-turbocharged straight-six petrol engine. Since the 1986 discontinuation of the BMW M106’s restricted manufacturing, it is BMW’s first turbocharged gasoline engine that is mass produced. The N54 was introduced in the 335i model of the E90/E91/E92/E93 3 Series lineup during the 2006 Geneva Motor Show.
The N54 started to disappear after the 2009 debut of its BMW N55 replacement. The E89 Z4 roadster, which was built until 2016, is the last vehicle to be powered by the N54.
Although the N54 does not exist in a BMW M configuration, it is used in the 1 Series M Coupe, 135iS, Z4 35iS, and 335iS vehicles.
How many horsepower can a BMW get from a twin turbo?
180 hp and 280 lb-ft of torque are produced by the 2.0-liter, 4-cylinder, TwinPower Turbo Diesel engine of the BMW starting at 1,750 rpm. With its 8-speed automatic transmission, it can easily go from 0 to 60 mph in just over seven seconds.
Is dual turbo the same as two turbos?
Sequential twin-turbo engines feature two turbochargers, but only use one of them—or, occasionally, both—for high speeds.
What distinguishes a turbocharger from a double turbocharger?
Essentially, these phrases have the same meaning. A car’s “twin turbo” or “bi-turbo” designation denotes the presence of two turbochargers in the engine.
The preferred terminology is different across various auto manufacturers. In V6, V8, or V12 engines, two turbochargers are frequently employed. A single turbocharger can be used for each bank of cylinders, which has several benefits for packing and efficiency.
For the majority of four-cylinder engines, one turbocharger is adequate. It is occasionally utilized in inline-6 and V6 engines as well.
You may have also heard the phrase “twin-scroll turbocharger”. Now, this doesn’t specify how many turbos were employed. It describes the kind of turbocharger instead.
When exhaust gases approach the turbine area of a turbocharger, they travel in a spiral pattern known as the “scroll.”
The exhaust tracts of consecutively firing cylinders are isolated all the way to the turbine’s mouth in order to eliminate gas-flow interference caused by the exhaust pulses.
The exhaust gases continue to maintain separate routes as they enter two distinct scrolls within the turbocharger unit’s body, giving rise to the phrase “twin-scroll.”
Twin-scroll turbochargers allow for somewhat more powerful tuning of engines than single-scroll models while also providing higher levels of gas-flow efficiency and less turbo lag. Many of the most recent engines employ twin-scroll turbochargers.
So keep in mind that twin-turbo and bi-turbo are interchangeable, but twin-scroll turbo is not.
Is the 3.0 twin-turbo BMW engine reliable?
2020 Wards 10 Best Engine and Powertrain Award winner is the BMW B58 TwinPower Turbo 3.0-Liter Inline Six-Cylinder Engine, which produces 382 horsepower. BMW B58’s 3.0-liter engine has won the Wards 10 Best Engine title twice in a row. BMW Turbo’s 3.0 liter inline 6-cylinder won the 10th Wards 10 Best Engine award.
What turbo BMW engines are there?
- TwinPower Turbo Inline 4-Cylinder 2.0-Liter Engine, 240 HP
- 300 horsepower 3.0 liter TwinPower Turbo inline 6-cylinder engine.
- Engine: 3.0 liter M TwinPower Turbo Inline 6-Cylinder, 425 horsepower.
- 560-hp, 4.4-liter M TwinPower Turbo V-8 engine.
- Engine: 6.0-Liter TwinPower Turbocharged V-12, 535 horsepower
What advantages do dual turbos offer?
Twin turbocharged engines have two turbochargers, as you would have guessed. If you answered yes, you were correct because twin-turbocharged engines fall under that category. When compared to the same engine without a turbocharger, engines with two turbochargers boost air and fuel intake by almost twice as much. Twin-turbocharged engines have tremendous performance as a result, which you’ll appreciate whether you’re driving, riding along, or just watching from the sidelines.
Twin turbo or single turbo—which is better?
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.
Does an automobile become faster with twin turbos?
More oxygen, less lag The twin turbochargers deliver water-cooled air to the engine to further fuel your drive. It accelerates more quickly because it is denser and richer in oxygen, which lowers turbo lag.
Do twin turbos have more efficiency?
Perhaps you’ve heard of a “twin-scroll turbocharger.” This does not, however, indicate how many turbos were employed. Instead, it describes the internal layout of the turbo.
The exhaust gases’ spiral path into a turbocharger’s turbine portion is known as the “scroll.”
The exhaust gases continue into the turbo by passing via two distinct scrolls within the turbine part of the turbocharger unit, hence the phrase “twin-scroll.”
Twin-scroll turbochargers are slightly more powerful than single-scroll models and provide higher levels of gas-flow efficiency, less turbo-lag, and engine tuning flexibility.
Even the BMW inline-6s now only require a single twin-scroll system, eliminating the necessity for two turbos. The term “twin-turbo power” has been replaced by “twin-power turbo” in BMW lingo.
A big displacement V-engine, like the one in the Mercedes-Benz AMG GT, is perfect for a twin-turbo arrangement.
How many HP are added by dual turbos?
Your engine’s output from a twin-turbo can increase by 100 to 250 horsepower. This is a fantastic technique to increase the power of your engine and help you reach some astounding speeds. Additionally, a twin-turbo can improve fuel efficiency and help you get the most out of your engine.
Just make sure to modify your engine in other ways to accommodate the extra power, or you risk damaging your vehicle the harder you push it.
Do twin-turbo engines require more gas?
For instance, Consumer Reports came to the conclusion that smaller, turbocharged engines often get worse gas mileage than larger engines without them. In comparison to their larger, naturally aspirated counterparts, Ecoboost Ford Fusions with turbocharged, four-cylinder engines consumed more fuel in the testing.
Which of BMW’s engines is best?
The M88, which powered BMW’s M1 supercar, was the company’s first M engine. It could produce somewhere between 215 and 282 horsepower with a redline of 6,500 RPM, which was a major thing when it was developed in the late 1970s. Additionally, it was employed in the BMW 3.0 CSL, which competed in the Group 5 race series and produced more than 800 HP at 9,000 RPM.
It was a strong engine that made one of the most beautiful engine sounds ever.
