what is the conversion rate of horsepower into C.C.'s? is there an exact ratio? and if so, what is it?

Answer 1

There is no direct conversion. Horsepower is a function of both displacement and engine speed (RPM). Usually, the more displacement, the more torque (twisting force).
What use the engine is put to determines how it is designed.
Let's say we want a high performance bike. We want a light engine that has a lot of power. To get the power, we'll design the engine to rev very high. The danger zone or red line will be above 11,000 RPM, or revolutions per minute. The cubic centimeters (cc) we'll put at 600. The horsepower will be over 100. That's a lot for a bike not much over 400 pounds. Top speed, over 150 MPH.
Let's look at another application. This time we want a bike that will carry a lot of luggage and a passenger on long trips comfortably. For this we don't need a lot of horsepower. What we need is torque. Engine size will be about 1500cc. Red line will be only 5500 RPM. Horsepower is only 70. Ah! but the torque will be over 70 pound-feet: a virtual locomotive. This bike will weight over 800 pounds. Top speed? Who cares; We just want to cruise along the highway, taking our own sweet time.

Answer 2

You can't convert horsepower into cc's they have nothing to do with each other. Horsepower is a measurement of output from an engine while cc is a measurement of displacement. For instance most 2-cycle motorcycle, atv, lawnmower engines are measured in cc's ex. 250cc 100cc, so on.

Answer 3

cc's, or cubic centimeters, ar an expression of the cylinder displacement, or size of the engine. The only relationship to horsepower is that a larger engine is usually (but not always) more powerful than a smaller one.

Answer 4

No conversion factor. There were many very large displacement engines in the old days that had very low horsepower, although some had tremendous torque.

Answer 5

Horsepower does not convert to CC's. CC stands for cubic centimeters which measures the cylinder volume inside of your engine. Also known as CI (cubic inches)

For example. a 350 CI motor would have approx. 5700 cc's ,otherwise known as a 5.7 litre engine.

BUT..... usually the more CC's, you have the potiential for more horsepower.

Answer 6

no there isnt. it all depends on the way the motor was made.like a 250cc built race 2-stroke can make 55 to 65 hp. a stock race 25occ 2 stroke makes 40 to 50 hp. were as a standard 250cc might make 18 to 35 hp. so no conversion on hp to cc.

Answer 7

A simple example to explain you that there is no ratio between HP and cc:
My Suzuki 1000 TLS is 135 BHP, and a YAMAHA 1000 R1 is 175 BHP ! Same cc, different power !

And how do you explain that in spite of this huge HP difference, my accelaration is better ? ;-)

V2 power !!!

Answer 8

There is no conversion because there are also many other factors such as compression ratio, # of valves, rpm, etc that will affect the power output.
