Maximum horsepower, or simply maximum power, refers to the highest amount of horsepower that an engine can produce under specific conditions. It is measured in PS (pounds per square inch) and represents the engine\'s ability to produce torque. This concept is closely related to the engine\'s revolutions per minute (RPM), as the higher the RPM, the greater the horsepower potential. However, it is important to note that maximum horsepower is only achieved within a specific RPM range, which is referred to as the maximum horsepower and torque curve.
