The horsepower of an engine is influenced by various factors beyond just its displacement (cc). Generally, a 165 cc engine may produce around 10 to 15 horsepower, depending on its design, efficiency, and intended use. For more accurate figures, it's best to refer to the manufacturer's specifications for the specific engine in question.
No.
About 165 horse.
21.5
Displacement doesn't directly equivocate to horsepower.
the cubic centimeters of 6.5 horse power is 175 cc
8.0 horse power - 125 cc
It's about 5.5hp
10 horse power
50 horse power
you can convert cubic inches to cc's but not horse power. an engine with say 65 cc's can have different amounts of horse power depending on carberation, pistons, valves etc. etc. etc. but my 65 cc engine does have 1.89 hp if that helps.
148 cc is 3.5
very hard to convert, about 2.5-3.5hp per 100 cc in mowers
