Single Turbo or Twin Turbo

The ideal way to get that sort of performance is through a turbocharger. You need not only know the basic concept and technology behind it – you also have to make a choice between a single turbo and a twin turbo, that is, if you want a taste of power.

A turbocharger is basically a turbine that is fuel-driven. Its function is to compress air in order to increase the power and the torque in the engine. Compressing air and increasing density heed more atoms of air and more atoms of fuel into the engine. All those things provide more power, more speed. Increasing air within an engine means harvesting more oxygen for the burn. The energy that results will drive the piston that will bring forth the compressed air.

Some cars come with a twin turbo engine. A twin turbo refers to an engine that has two turbochargers to handle the compression. Let us discuss some of the differences between the two.

Twin Turbo, produce power faster using 4 cylinders each turbocharger for the spooling. There is less lag in this setup. Boosts are achieved at lower RPMs. Ideal for everyday driving on the streets. Setup costs more than installing a single turbocharger. Twin turbochargers are best for V-type of engines. Smoother operation of the engine. Two smaller turbochargers are cheaper than a large one.

Single Turbo, a single turbo requires all 8 cylinders in order to build some boost, produces good results for drag racing, which needs extremely high power, single turbo engines are easier to set up. There are super large single setups that can support up to 1500BHP, can create real power but there is that unwanted lag. Some problems may occur in the setup but they are easier to fix and less expensive too. Doesn't take up much space in the car. Better cooling, Higher boost at high RPMs, There is considerable lagging and easier to plumb since there is no need for cross-plumbing of the exhaust

Recommendations; Below 900bhp requirements can be handled pretty well by a single turbocharger but if you want to reduce the lag, two smaller turbochargers are the way to go. For an engine with a V-type layout, go for the twin turbo setup. For an engine with an Inline layout, go for the single turbocharger.

There are some cars that came out of the factory with twin turbo systems that are being converted to single turbochargers. There are some who want to change their single petrol turbo with the twins. This really depends on what car and engine are concerned, as well as the preferences of the owner.
