cc to horsepower

    Snowblower season is now upon us. Going to buy a new snowblower this year? But you don't know how powerful it is? Here is an approximate cc to horsepower chart for small engines. This chart ONLY gives an IDEA of how much horsepower CAN BE achieved by a stock engine of that CC size. There are too many variables, such as carb size, muffler flow, timing, valve duration. Some of these were taken from ads that stated "replacement 179 cc engine for 5hp snowblowers". This just lets you know that a 179cc engine can NOT be a 10 hp engine. Hope this helps in deciding which snowblower you buy.

    123 cc = 4 hp
    179 cc = 5 hp
    208 cc = 5.5 to 6 hp
    277 cc = 7 to 8 hp
    291cc = 9hp
    305 cc = 9 to 10 hp
    342 cc = 11 to 12 hp
    357 cc = 13 hp
    420 cc = 13-15 hp
