Sequential Turbocharging
Sequential turbocharging uses a small turbo at low engine speeds and adds or switches to a larger turbo at higher speeds.
What is Sequential Turbocharging?
The small turbo reduces lag at low revs. The large turbo provides power at high revs. Valves control which turbo is active. Some diesel engines use a similar two-stage arrangement for high torque across the rev range.
How it works
Exhaust flow is directed to one or both turbos depending on engine speed and load.
Why it matters for your car
The extra valves and pipes add complexity. A sticking control valve can cause a sudden drop in power.
