The formula that works best only applies to the small newer normally aspirated (carbureted) 4 cycle engines. The ratios change slightly worse with altitude and slightly better with fuel injection and tuning. Most American mowers and the newer 4 cycle outboard motors fit into one of these two formulas: Typical new carbureted engine well tuned: 1 x HP per each 25 cc Fuel injected: 1 x HP per each 22 cc Notes:-Most engines are tuned down to a lower HP for better engine life. -It is common for the same cc engine to be built in 3 different HP versions with the highest rated being the maximized HP per cc version. That is how you see price and HP changes on the same cc engine made by the same company. -Some of the newest (2008 and newer) engines from Japan perform slightly better. A typical 150cc motor should equate to between 3.5 - 6 HP+ depending on tuning with 5 HP being the adv.
The actual formaul plots as a curve and not linear but does not apply to Max/High Performance engines like motorcycles.
1 HP is about 15-17cc.
Therefore, 208cc is probably about 12HP. (208/17=12.2)
That is, using 17cc to 1HP, since there are many variables such as engine condition and design which can affect HP. So, I used 17cc since it is the more conservative conversion factor.
Look for the HP in the manufacturer's specs for the claimed value, but use my method for a ballpark figure.
1 hp is equal to 0.746 kW.
51 kW is equal to approximately 68.4 horsepower (hp).
1 horsepower (hp) is approximately equal to 0.7457 kilowatts (kW).
One hp is approximately 756 watts.
One horsepower (HP) is equivalent to approximately 0.746 kilowatts, so 100 HP is equal to around 74.6 kilowatts.
Six hp, according to the conversion tables.

Approx. 7.5 hp
6.5 hp
Northern Tool Company claims that the newer 208cc engines are "direct replacements" for worn out 6.5 HP engines. They list this under "historical data". http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200362863_200362863
There is not set answer for translating displacement to HP because of engine type and carburetor variations.
208cc is what in horse power for a snow blower??
There is no definite answer to this questions, but in general, you'd be looking at 5-6hp
The 208cc mini bike can travel at 40 miles per hour.
it varies, they use the same size block for multiple outputs, they stopped using horsepower numbers because of legal reaons, most are 5-7hp
All of it.
A 208cc engine would be a 8.32 Horsepower engine. The math goes like this... 1 x HP per each 25 cc for conventional engines. It is slightly lower for fuel injected engines, about 22 cc.
