To convert cubic centimeters (cc) to horsepower (hp) for a snowblower, a rough estimate is that 1 horsepower is typically equivalent to about 15-20 cc for small engines. Using this estimate, a 347cc engine would roughly translate to about 17-23 horsepower. However, the exact horsepower can vary depending on the engine design and efficiency. Always check the manufacturer's specifications for precise conversions.
8hp-14hp
13.5
A 179 cc engine is around 5.5-6 horsepower. There's no hard and fast rules on cc to hp conversion there are too many variables.
divide the cc by 15 to get the horsepower.
11 horsepower
Approx. 7.5 hp
Its between 5 to 6.5 hp.
12 hp
A guess-timate rule of thumb is 25cc per horsepower. So your snow blower would be about 7 horsepower.
between 9 and 11hp
13.6
318cc. is 8hp. 305cc.is probably between a 6 to an 8hp.
