It’s when an engine has two turbochargers pushing extra compressed air into the combustion chamber to get the “boost”. The turbochargers can be different sizes and can be laid out in different configurations to get the final effect you want.
Twin-turbo (not to be confused with a twincharger setup, which is a combination of a supercharger and a turbocharger) refers to an engine in which two turbochargers work in tandem to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine ).
How does a twin turbocharger work?
How does twin-turbocharging work? A twin-turbocharger works by using two turbochargers of the same size to force air into the engine’s cylinders to add extra horsepower. The exhaust gases are recycled, split between the two turbos, and usually combined in a shared inlet before entering cylinders.
What are the different types of twin turbos?
The most common twin-turbo designs are sequential and parallel. The latter involves the use of two turbochargers of the same size working together as one massive turbo. With this layout, the exhaust gases are routed to both turbos equally.
What is the difference between BMW TwinPower Turbo and Biturbo?
twin turbo technology employs two turbochargers that are placed one next to the other (“twin”) biturbo employs 2 turbochargers as well, yet they are located one on each side of the cylinder bank (typical for V8 engines) BMW TwinPower Turbo is relying on a single turbocharger with two scrolls
Is a twin turbo V6 faster than a V8?

Is a turbocharged engine better than a V-8?
A turbocharged engine has a great sound, but it is more high pitched and buzzy than a naturally aspirated V-8. Having said that, there are plenty of exhaust and camshaft kits that you can buy aftermarket to help a V-6 sound more V-8 like, but you can never exactly replicate the sound or feel of that V-8 muscle.
What is the difference between V6 and V8?
The V8 is designed for being pushed. When you step on the gas pedal, you can expect a quick response and access to the power you need. Not only will the V8 engine have a higher top speed than a comparable V6, but it is better equipped to produce faster acceleration times.
What are the advantages of a V-6 engine?
The V-6 also makes weight less of an issue when driving around curves, corners, and turns. This is due to the fact that V-6 engines have two fewer cylinders. V-6 engines have improved performance compared to V-8 engines, especially when timing acceleration properly because there’s less tendency to drift to the outer edge.
Which V8 engine has the most horsepower?
You will be able to get the most power from a V8 engine. Take the 6.2L HEMI High-Output Hellcat Redeye V8 engine that outputs 797 horsepower as an example. This is power that no V6 engine can stand toe-to-toe with.
Can you triple turbo a car?
The triple turbo setup is a sequential solution. A small turbocharger provides a boost at low rpm, so that the engine can develop more torque right after idle, and this happens thanks to variable geometry. Shortly after, a big turbo supplies more boost for high torque in the low-to-mid range of revs.
Should you drive a turbocharged car?
Here are the dos and don’ts of driving a turbocharged vehicle. Follow these maintenance and driving tips to ensure you get the full benefit out of your turbocharged engine. Adding in a turbo makes a car’s engine run even hotter than a normal vehicle. For this reason, engines with turbos are more prone to overheating.
Are two turbos better than one?

It was also among the first turbocharged vehicles of from any marque, beat to market roughly ten years prior by the Oldsmobile Jetfire.
Can you twin turbo a 4 cylinder?
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.
Can you twin turbo a V6?
Three types of twin-turbo layouts It’s best used in “v” engines (V6 and V8) because then each turbocharger can be assigned to one cylinder bank, which cuts down on the amount of exhaust piping needed for the system.
Does twin-turbo give you more horsepower?
A twin-turbo engine should be able to improve 20 – 60% of horsepower, which equates to a 40 HP – 650 HP boost to your engine.
Does a turbo boost increase horsepower?
On any naturally aspirated engine, if you add 14.7 psi of boost with a turbo, then the maximum horsepower the turbo setup would produce is double. Put another way, 14.7 psi of boost can add 100% more horsepower to your engine. Now that example only works for 14.7psi. The horsepower doubles because 14.7 psi is the atmospheric pressure.
Why is a twin turbo engine better than a single turbo?

Are turbocharged engines more fuel-efficient than naturally aspirated engines? In theory, turbochargers can boost the efficiency of an internal combustion engine by anywhere from 10 to 30 percent.
Does a smaller turbo engine use less fuel?
If the engine can deliver enough power to cruise at freeway speeds without bringing the turbo into action, that requirement for extra fuel when boosting obviously doesn’t come into play, and in these conditions, the smaller turbo engine will use less fuel.
Is a non-turbo engine better?
The increased engine revolutions needed to produce adequate power can cause a non-turbo engine to experience lower fuel economy, especially at cruising speeds. Some of the most fuel efficient production engines are turbocharged diesel engines. Turbodiesel engines are capable of safely running a much higher turbocharger pressure setting.
Do turbocharged engines affect real-world fuel economy?
Some people will be quick to point out that some turbocharged engines don’t quite meet published fuel economy estimates provided by the government. There are a few reasons this could be the case. However, a number of experts believe that real-world fuel economy scores for turbocharged engines are negatively affected by the driver.
Are turboprops more efficient than Jets?
TAS has no dependence on air density. For short distances, turboprops are more fuel efficient than jets. On the longer flights, the jet (turbofan) engines win the race. Turbofan engines perform best at high altitudes. At medium and low altitudes, the turboprops are more efficient engines.
Why is twin engine better?
