So, for an 805cc engine, you can use the following calculation:
Power = (Displacement in liters) x 100
Power = 0.805 x 100
Power ≈ 80.5 horsepower
Therefore, a ballpark estimate for an 805cc engine is that it may have around 80.5 horsepower. However, actual horsepower values can vary based on several factors, such as the specific engine design, engineering optimizations, and the fuel used.
