Default Re: How to covert CC to horsepower

I need to know how to convert CC's into Horsepower too.

Now Snow throwers from Sears are made with Craftsman Engine which are made by MTDs. These engines are rated in CC's and not horsepower anymore. Don't understand the need for this things. A couple of years back Briggs and Stratton did the same thing with their smaller engines in Lawn Mowers and converted Horsepowers into CC's.

Basically Snow throwers have the following ratings:

123 CC (for the lightest snow)
179 CC (For medium snow)
250 CC and Above (for heavy snow).

How much is 123 CC equal too? Last year Craftsman had a similar Snow thrower for 4 HP which had the same features as 123 CC. So I am assuming its pretty much the same power, except that it is now made in CCs. 179 CC snow thrower was equivalent to 5 HP and 5.5 HP last year and 250 CC was equivalent to around 7 HP and above. So I am not sure how to convert CCs into HP. In fact, more CC's mean more Horsepower because the more volume is displayed by the pistons, the more faster its going to complete one revolution resulting into more power.

However, in Lawn mowers they are made of 190 CC or 6.75 Torque (they have two ratings) by B&S. These lawn mowers were equivalent to 6.0 HP and 8.75 Torque with 190 CC was around 7 HP. So I am confused now. What is the exact method of converting CCs into horsepower.

This is insane, I love it! Horsepower is the direct result of just how much air/fuel you can cram into the cylinders and get reliable, efficient combustion short of having raw gas drip out the tail pipe. Take any engine and increase valve lift with a differnt cam and you get more power; same with a bigger (or better carb) bigger valves...the list goes on but this can be done without changing the "CC" or cubic inch one bit. It's just physics, more gas and air, bigger boom, more power. I say if it can move your *** without straining, it has enough horsepower. Be happy.

Smile Re: How to covert CC to horsepower

FYI only.
cc's are as expressed in cubic centimeters. This only refers to the displacement of the piston to it's sleeve in the power plant and not related to h.p. The variables are to numerous to mention the different hp's available for the same displacement size. However if you know the kw of the engine or other power plant you can convert directly to hp. .746kw is equal 1 hp.
ex. if you have 8.110kw and you divide by .746you would have a 10.87 hp.
hope this helps.

Question Re: How to covert CC to horsepower

litre to cc is 1litre =1000cc, thats all you can figure out
like mentioned before cc (cubic centimeters)is engine size not torque or hp. In lameman terms the bigger the piston the more hp, and usually big engines have big pistons, which means bigger valves etc. The bigger and hotter the explosion the more power.

This thread seems to have been beaten to death so I am going to close it.

Please start a new thread for any horsepower questions you have.

Thank you.
