Powerful engines are typically characterized by their high performance and efficiency. Turbos (6 letters) are a type of engine that uses a turbine to increase the power output of an engine, while VEIGHTS (7 letters) is a type of engine that uses two banks of four cylinders in a V-shaped configuration. Both types of engines are used in many applications, from cars to airplanes, and are known for their ability to generate a lot of power.
