You cannot determine horsepower from cubic centimeters no cubic inches. For example, a 125 cc 2 cycle Motocross racing motorcycle produces upwards of 25 HP yet a 140 cc lawn mower engine produces about 3 HP. There is no correlation between the cc's and horsepower whatsoever.

roughly 342 cc's to a 12 hp engine
7.5 hp
how much cc's is a 6.5 hp engine
To convert cubic centimeters (cc) to horsepower (hp), a rough estimate is that 1 hp is approximately equal to 15 cc for small engines. Therefore, for a 40.9 cc engine, you can estimate that it produces about 2.73 hp (40.9 cc ÷ 15 cc/hp). However, this is a general approximation, and actual horsepower can vary based on engine design and efficiency.
Number of cc's alone does not tell you HP of an engine.
