What does twin-turbo technology mean?

[RafaelDella]

Dual turbocharging refers to a forced induction system that employs two independent turbochargers, typically installed on larger displacement engines such as inline-6 or V-type configurations. When both turbochargers operate simultaneously, intake efficiency is significantly improved, boosting effects become more pronounced, and power performance is greatly enhanced, which can mitigate turbo lag but not completely eliminate it. At low engine speeds, only a low-speed turbo operates, requiring less exhaust flow to drive the turbine at high speeds and generate sufficient intake pressure, thereby reducing turbo lag. As engine speed increases, the high-speed turbo engages, entering a high-boost state to deliver consistent and robust power output.
