Unlike other twin-turbo systems, 2-stage variable twin-turbo employs different size turbos - a small one for quicker spool up at low rpm and a large turbo to take care of higher rev. They are connected in series so that the boost pressure from one turbo is further multiplied by another turbo, hence the name "2-stage". The distribution of exhaust gas is continuously variable, so the transition from small turbo to big turbo can be made seamless. Below is an example taken from an Opel system. Let's see how it works:

 

Below 1800 rpm
The exhaust flap is closed. All the exhaust gas drives the small turbo, which provides all boost pressure in this phase. The large turbo runs idle and does not contribute to compression.

 

 

 

 

 

 

 

 

 

 

 

 

1800-3000 rpm
The large turbo is now brought into action, so that both turbos run together. Depending on load, the exhaust flap opens increasingly and feeds exhaust gas to both turbos. The large turbo pre-compresses the air, which is then cooled in the intercooler and raised to higher boost pressure in the small turbo. 

The check valve remains closed, since the large turbo's boost pressure is still lower than that of the small turbo.

 

 

 

 

 

 

 

 

 

 

 

Above 3000 rpm
Only the large turbo compresses the air, because more air can flow through it than the small turbo. The exhaust flap is now completely open and the entire exhaust gas flows through the large turbo, which produces maximum boost.

The check valve is opened by the gas flow from large turbo. This bypasses the small turbo.
