At what RPM does turbocharging kick in?
1 Answers
Turbocharging generally kicks in at around 1500 RPM. The specific RPM at which turbocharging engages is related to the engine displacement - the larger the displacement, the lower the engagement RPM. For example: a 1.4L engine engages at around 2000 RPM, a 1.8L at around 1500 RPM, and a 2.0L at around 1000 RPM. The main function of turbocharging is to increase the engine's air intake volume, thereby improving the engine's power and torque, making the car more powerful. When an engine is equipped with a turbocharger, its maximum power increases by more than 40% compared to when it doesn't have one. When the turbo engages, the power output becomes more aggressive, and you can feel the acceleration push (commonly referred to as 'kick-in' sensation), which is also a way to determine turbo engagement.
