The output of a 150 cubic centimetre engine is around 10 horsepower. 1 horsepower corresponds to between 15 and 17 cubic centimetres, under SI Metric.
Cubic centimetres refer to the volume of an engine’s cylinders, however they do not correspond to an accurate power output. Although the number of cylinders in an engine has a significant impact in its power production, it is not the only factor that must be considered. The exact conversion between cubic centimetres and horsepower is determined by analysing the engine’s overall size, its tuning, and the type of fuel utilised. The type of fuel is a crucial consideration because it has the potential to significantly impact the engine’s horsepower. A 150-cubic-centimeter-cylinder engine that utilises a volatile fuel type, such as nitrous oxide, has the potential to produce much more horsepower than a standard-fuel engine.
Additionally, there are other meanings of horsepower, including brake horsepower and shaft horsepower. The brake horsepower is the output before other engine components begin restricting overall power, whereas the shaft horsepower relates to diesel engines.
