The formula that works best only applies to the small newer normally aspirated (carburetor) 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 formula plots as a curve and not linear but does not apply to Max/High Performance engines like motorcycles.

How many cc in 8hp?
You need to know the cubic inch not hp to convert to cc.
Describe an energy conversion you have observed in your own life?
hp
What is the conversion of 254 CC to horsepower?
254ccis how many horse power
How much hp is 900 cc?
Horsepower and cubic centimetres belong to different measurement scales and cannot be directly converted. However a general rule of thumb is that 15 cc is approximately equal to 1 hp for smaller engines
Does .5cc .38ml?
The conversion between ml and cm cubic are given .On finding the relation we get as follows . 1 cc=1 ml.=0.88 cc or 0.88 mL.
What is conversion for 183 cc to horsepower?
There is none. A 133 cc engine can have varying hp depending on many things.
What is conversion for 179 cc to horsepower in a Sears snow blower?
5 hp
What is the conversion for a 205 cc to hp in a Briggs and Stratton motor snowblower?
13.6
277 cc converted into horsepower?
I understand that a 250 cc engine is around a 15 hp motor, so a 277 cc engine calculates about 16.5hp. there is no direct conversion between cc and hp because cc is a volume and hp is a energy.
How many cc is 6 HP?
A little over 250cc The easiest conversion is to take the (hp x 42.3) = cc this of course is not exact but very very close... 253.8cc
What is 338cc in horsepower?
There is no standard conversion from cc's to hp. But as a guide, 338cc = aprox 11hp
179 cc hp?
150 cc a hp
What is 5.5 hp in cc?
What is 5.5 hp in cc?
How much is 1001 HP in CC's?
1 HP= 15 CC so 1001 HP= 15015 CC's
What is the HP of 203 CC?
7hp
How much horsepower does a snowblower 179 cc engine equal?
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.
How many HP is equl to CC?
If you mean HP=Horsepower, and CC= Cubic centimeters then HP does have anything to do with CC's. Cc's are the size of the displacement of the engine. HP is the amount of power the engine produces.
