There is no correlation between C.C's and horsepower. For example, a 125 CC motor cross bike engine puts out about 28 horse power yet your Briggs 160 CC engine is likely 4.5 horse power. However, you can convert volume to torque and then convert torque to horse power. Actually, a flat head carburetor engine, as a general estimate, is 1 lb. ft of torque per 25 CC's. So your 160 cc Briggs should be about 6.5 lb ft of torque. If you use the formula; torque x rpms/5252 or 6.5 x 2800/5252 =3.5 HP @ 2800 RPM's. Since peak torque rpm vary, lets say it delivers 6 lb ft @ 3600 rpms that puts it at about 4.8 HP@3600 rpm's. Since the small engine manufacturers have no idea what type of equipment there engine s going to be used in, allowances of 20% are considered acceptable. The manufacturers test for torque ( a dyno records torque (twisting force) and calculates horse power from the torque) on a dynomometer with no muffler, air cleaner, cooling fan or any accessories on the engine, if they rate it for x horsepower, that number is derived from an engine tested at peak horsepower with no parasitic loads nor restrictions to the air flow into and out of the combustion chamber. However, lets just say that Toro purchases some 160CC quantum engines which Briggs has rated for 4.5 hp. Toro then installs an exhaust, cooling fan, cooling shrouds, an air filter and then set the engine speed for 3,200 RPM's so not to exceed the maximum mower blade tip speed, horsepower will be substantially less than what the dyno test bore out without the parasitic loads and at the higher engine RPM's. Toro, rather than testing the engine as installed which would be around 3 hp, they label them with the peak torque number because the engine produces it's maximum torque at about 3,000 RPM's. This is used as a marketing ploy since 6.75 torque sounds more powerful than 3.5 horsepower does.
If Toro where to use the engine on a snow blower, which has a much less restrictive exhaust, no air filter and a low flow cooling fan they would likely rate it at 5.5 hp. verses the torque rating. Why; the torque drops off significantly above 3,200 rpm's so the horsepower number is the larger of the two.
An example that shows an under rated engines are the old cast iron Kohler K-series engines. The K-301 (480 cc) is rated at 12 hp and yet it has 27 lb ft of torque at 2800 rpms which equals 12 hp, at 3600 rpms they put out in access of 14 hp. The K-482 is rated for 18 hp and yet it has 37 lb ft of torque! That puts it at around 22 hp at 3600 rpms.
So...your 160 cc Briggs flathead engine is likely 3.5 HP actual as installed on your equipment unless it is a snow blower.

How many cc is a 5.5 Honda lawn mower?
A Honda lawn mower with a 5.5 horsepower engine typically has a displacement of around 160 cc. This measurement can vary slightly depending on the specific model, but 160 cc is a common displacement for engines in that horsepower range. Always check the specifications for the exact model for precise information.
How much horsepower does a Honda 160 cc lawn mower engine have?
4.4 H.P. and 6.9 ft/lbs of torque
How much horsepower does a 420 cc riding lawn mower have?
14
How much horsepower does a 145 cc lawn mower have?
There is no correlation between hp and cc, for instance, a 125cc motocross bike delivers around 25 hp, a 480cc briggs I/C flathead delivers 12 hp. The 140cc flathead lawn mower engines are between three and four hp.
Does higher cc equate to more power in a lawn mower?
Generally it does. However a lawn mower can have a higher horse power than another brand mower, even though it has a lower cc. There is no general equation for converting from cc to horsepower for all engines and the conversion will depend on several factors such as the efficiency of combustion of the gas/air mixture, spark plug position, speed of the engine etc.
What is hp for 125 cc lawn mower?
The horsepower (hp) for a 125 cc lawn mower typically ranges from about 3 to 5 hp. This power output is adequate for residential mowing tasks, allowing the mower to efficiently handle small to medium-sized lawns. The specific hp can vary based on the engine design and manufacturer specifications. Always check the mower’s manual or product details for precise information.
How many cc is a 7.5 hp lawn mower?
The engine displacement of a 7.5 hp lawn mower can vary depending on the specific design and manufacturer, but a common estimate is that it typically ranges from about 200 to 250 cc. Horsepower and engine displacement do not have a direct conversion, but this range is generally accepted for small engines in that power category. Always check the manufacturer's specifications for the most accurate information.
How many horsepower is 10 cc?
That is impossible to calculate with just the number of cc. cc stands for cubic centimeter, so imagine a cubic centimeter and multiply that by 10. That is the size of your lawn mower's combustion chamber. if you want to know the HP, look in the manual or on the engine packaging.
How many CC's does it take to make a horse power?
That depends on many things. Simply there are fewer CCs per horsepower in a highly tuned racing car engine than in a lawn mower engine.
How much horsepower in 346 cc?
The horsepower produced by an engine depends on various factors, including its design and efficiency. Generally, a 346 cc engine might produce anywhere from 10 to 30 horsepower, depending on its application (e.g., motorcycle, lawn mower, etc.). For a more accurate estimate, it's best to refer to the specific engine manufacturer's specifications.
What kind of oil for a Craftsman 190 cc front propelled lawn mower?
Any 2-stroke mower type will serve.
How much horsepower in a 139 cc lawn mower ENGINE?
Well, friend, a 139cc lawn mower engine typically has around 3-5 horsepower. It may vary slightly depending on the specific make and model, but that's a good ballpark estimate. Just imagine all that power gently guiding you as you create beautiful landscapes in your yard.
