How much power and torque does the BMW N74B66 have?

From the factory the BMW N74B66 makes 448 kW (610 HP) and 800 Nm of torque. It is a 6.6 liter (6,592 cc) v12, DOHC, 48 valve petrol engine with twin turbochargers.

Because it is turbocharged, the torque comes in low in the rev range, which makes the car feel strong in everyday driving. A healthy turbo, a clean intercooler and tight boost pipes are key to getting the full figure.

A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.
