How much horsepower does a turbocharger give you?

The amount of horsepower a turbocharger can provide depends on several factors, including the size of the engine, the size of the turbocharger, and the boost pressure. Generally speaking, a turbocharger can add anywhere from 20 to 200 horsepower to an engine. For example, a small turbocharger on a 2.0-liter engine might add 20-30 horsepower, while a larger turbocharger on a 5.0-liter engine could add up to 200 horsepower. It's important to note that adding a turbocharger to an engine can also increase the amount of torque it produces, which can make the car feel more powerful even if the horsepower doesn't increase significantly.
