how fast is 206cc
Since HP and displacement are not directly related, I can only say that it is probably in the neighborhood of 200cc.
5.5 hp
Its between 5 to 6.5 hp.
13.6
A 291 cc snowblower engine typically produces around 8 to 10 horsepower. The exact horsepower can vary based on the engine design and manufacturer specifications. Generally, smaller snowblower engines in this range are designed for residential use, providing sufficient power for light to moderate snow removal tasks.

8 to 10 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.
See this link for a complete table. The ratio is not constant because the relationship depends on other factors. http://www.simetric.co.uk/si_cc2hp.htm how munch hp in a208 cc snowblower
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
