The hp is not determined from the cc. However there is a relationship between hp and engine volume (CC). For most engines the larger the volume, the greater the hp (this doesn't always hold true however).
150 cc a hp
I was thinking closer to 150 cc but it's not an exact science.
Around 4/5 hp.
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.
No direct equivalent. Engines of same cc may have different hp.
Seems to be 6 hp.
The horsepower (hp) equivalent of an engine's displacement in cubic centimeters (cc) can vary depending on the engine's design and efficiency. However, a rough estimate is that 179 cc might produce around 5 to 10 hp for small engines, such as those in motorcycles or lawn equipment. For more precise values, it's essential to consider specific engine specifications and performance characteristics.
5 hp
how many cc is a 13 hp
To convert cubic centimeters (cc) to horsepower (HP), you can use a rough estimate that 1 horsepower is approximately equivalent to 15 cc in a typical gasoline engine. Therefore, 382 cc would be roughly equivalent to about 25.5 HP (382 cc ÷ 15 cc/HP). However, this is a general estimate and actual horsepower can vary based on engine design and efficiency.
To convert horsepower (hp) to cubic centimeters (cc), the relationship depends on the engine type and efficiency. Generally, for small engines, about 15-20 cc is often equivalent to 1 hp. Therefore, 11.5 hp would roughly correspond to approximately 172.5 to 230 cc, depending on the specific engine characteristics.
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
