At what speed do turbos kick in?

In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that’s up to 30 times faster than most car engines can go.
