Due to their ability to vary the area-to-radius ratio, these types of turbochargers result in wider boost ranges and
shorter gap times that match engine RPM. This design allows the ratio of the turbocharger to change when the
position is changed.

5 Variable Twin Scroll Turbo
The variable twin-scroll turbo combines a twin-scroll turbo and a variable geometry turbo. This turbo allows for
great high performance in any vehicle. This design provides exhaust airflow to be directed in only one scroll.
In addition, it also provides the amount of valves to open to split the gas between the two scrolls if necessary.
The VTS turbocharger design offers a cheaper and more powerful alternative to the VGT turbo, which is a good
choice for petrol engine applications.

6 Electric Turbo Electric Turbo

Types of Turbochargers Electric turbos are the latest and most recent addition to the turbocharger industry. It
is completely different from other types of turbochargers. They reduce turbo lag and aid normal turbocharger
operation at low engine speeds. This is done by connecting an electric motor that rotates the compressor at low
revs from start until the exhaust volume is strong enough to operate the turbocharger. A disadvantage of this type
of turbocharger is that they are quite expensive and complex. This turbocharger option also allows the recovery
of used energy and use for power generation.
