1 hp is equal to many cc?

Answer 1

You can't really answer it, there are too many factors to give a direct answer. You have the fuel, combustion ratio, intake flow, exhaust flow (restricted gives more torque, open gives more hp), piston shape, squish, timing, and more.

For the most part a naturally aspirated highly modified engine is putting out 200 hp/ litre, a v-twin about 100+ stock. There is a formula for the fuel you use, 1 Btu/hr = (1 x 0.0003929) Horsepower = 0.0003929 Horsepower.

Bugatti figured this all out to achieve the fastest production car, Veyron, and using a 16 cylinder to achieve the maximum rpm, because of the fuel consumption (btu's) needed to get 256mph.

Answer 2

Even though this is an older trend, here goes. What people are looking for is what the crooked businesses took away. There are not all these variables when the engine is run on a dyno and peak hp was labeled on the engine. So whether it was injected or turboed that might be a variable in a chart but running on a dyno automatically takes in all the variables. When I was young a 3hp push mower would cut anything, so when I bought a 4hp Sears mower I thought with an extra hp it would mow our yard. Not if they lie about the hp, the thing must have 1hp. Here's a general chart of cc to hp with a basic engine.123 cc = 4 hp
179 cc = 5 hp
208 cc = 5.5 to 6 hp
277 cc = 7 to 8 hp
291cc = 9hp
305 cc = 9 to 10 hp
342 cc = 11 to 12 hp
357 cc = 13 hp
420 cc = 13-15 hp

Answer 3

What Mushki doesn't understand or explain is what exactly horsepower is... it's nothing but torque related to engine RPM. Horsepower is great, because it'll speed you down the road. But what yanks you, pushes you back in the seat, is TORQUE. And those big Harley V-Twins make it huge numbers. Ever noticed how your Honda comes alive at 8000 rpm? Doesn't pull really hard until then? Try riding a Harley... The power band is almost flat from idle all the way up! Horsepower is not everything!

Horsepower = (torque * rpm) / 5252. So while that Honda may generate 100 HP, it needs 15000 rpm to do so, while that Harley can generate all of it's HP at 2000 rpm. Which makes the Harley much easier to ride, in any gear. Period. Not a lot of shifting required to move along.

I realize this is a little off topic. And to answer the question, there is NO direct conversion from cc's to horsepower. But in a very general sense and with all things being equal, more cc's make more horsepower.

Answer 4

Cc To Horsepower Conversion

Answer 5

4 wheeler nut's answer isn't exactly correct. Sure, overseas outfits measure small engines in cc's but so do American builders of both small and large engines. They may use liters, but a liter is 1000 cc's. In other words, a 1,400 cc bike engine is 1.4 liters plain and simple. As others said, equating horsepower to displacement is applicable only to a specific engine. High reving Jap sport bike engines make more hp per cc than does a slow turning Jap or American cruiser bike engine. In addition, 2 stroke engines do not make double the hp of a 4 stroke for a given displacement. Too much to go into here, but it involves cylinder filling effeciency as well as exhaust port effeciency loss.

Answer 6

Convert Cc To Horsepower

Answer 7

At 4PM PST, 1 HP is equal to exactly 0.187 CC. But tech stocks are on the rise so don't give up on Circuit City just yet.

Answer 8

there are no direct conversion between hp and cc
a 600cc engine can give you anything between 50 and 120 HP so you cant compare hp to cc

Answer 9

There are a lot of different answers out there.

There is also a lot of variables out there to.

Look at this a Funny car runs a 500ci motor but because of the fuel (99% Nitro 1% methane) and power adders like a 18-71 Blower on the top make the engine produce 7000+ HP. wehre the NASCAR guys are running 350ci and putting out about 900 hp. Then you have indy cars. running 183ci and putting out over 650hp.

It all depends on how teh engine is built. Any power adders on it and many other things. like fuel used.

Answer 10

If you mean horse power to cubic centimeters they are two different types of measurement... A equal doesn't make sense... Maybe hp per cc... For example a 600cc motorcycle making 100 hp would be 1 hp per 6 cc..........
