it varies, probaby between 7-8,
Horsepower has NO direct relationship to capacity ! A 310 cc engine could be anywhere from 8 to 120 hp. CC is ONLY the swept volume of the engine
This is from movingsnow.com: Here is a simple chart of approximate cc to torque to horsepower conversions. It's not exact, but it will give you a better idea of how big the new engines are. I used 3600 rpm in the formula for this comparison. 179 cc = 5 hp 205 cc = 8 to 9 Gross Torque = 5.5 to 6 hp 250 cc = 11 to 11.5 Gross Torque = 7 to 8 hp 305 cc = 13.5 to 14.5 Gross Torque = 9 to 10 hp 342 cc = 15.5 to 16.5 Gross Torque = 11 to 12 hp
Displacement and HP are only related to each other in a range because of engine variations. I agree but was curious how did you get the cc of a lawnmower? If it is a lawnmower the hp comes out with an educated guess of about 12 hp.
Hey 8
You are asking about apples and oranges. One is not directly related to the other in order to tell you the exact cc of a 8 hp. However a typical 8 hp motor is around 200 cc.
2500cc
240cc = 8 HP
It depends on the horse-power of the engine. 220 cc would be about 8-10 HP, equivalent to a 6-8 HP electric motor. But a small petrol engine is usually not used at full power continuously, so manybe a 5 HP motor would do the job.
Horsepower cannot be converted to cc, because hp is a unit of power and cc (cubic centimeters) is a unit of volume. You can read about horsepower at http://en.wikipedia.org/wiki/Horsepower. You can convert cubic inches (ci) to cc. One cubic inch is equal to about 16.4 cc. Put another way, one liter (1000 cc) is equal to about 61 ci. So a five-liter engine in a car has about 305 ci of volume in its cylinders. But one 5-liter engine can put out horsepower that is different from another 5-liter engine. For example, the Ford Mustang 5.0 V8 engine is actually 4.6 liters, and it is rated at 300 hp. Ford has also used a 4.6 liter V8 engine in trucks, and it is rated at just 231 hp.

There are 240 cc in 8 oz. Each oz. is 30 cc.
