Ok, stupid question, new vehicles are all listed by liters for engine size. Years ago I remember always touting the horsepower. How can I can convert a 4.7 liter engine to horsepower?

The amount of horsepower output by an engine depends on more than just the engine size. For example, a tricked out 4.7 liter engine will have more horsepower than an old stock 4.7 liter engine.

You wont be able to convert directly between them. For new cars you may be able to find data sheets that lists both engine size and horsepower. Otherwise you would have to take it to a shop to be placed on a machine to measure it.

does it give a power output of any description? This should convert directly to horsepower. Otherwise, what sort of engine? - Mrs X

If you look at cars on MSN Autos for example, you'll see the Ferrari F430 generates 490 HP with a 4.3 Liter V8 Engine. An Aston Martin DB9 has a 5.9 Liter V12, but only generates 450 HP. There are many other factors that determine horsepower other than engine size, as you can see. I recommend www.autos.msn.com if you are still looking for a car.

example: Ford engine, 8.1 liter. How close is this to the 534 cu.in.?

You can convert engine size easily on the volume conversion page.

8.1 liter is about 494 cubic inch

what you are asking is not liters to horsepower but liters to cid. right? ok a stock 4.3 in a s10 has a cid. of 262 and horsepower rating of 165. hope this helps. (show_blazer@yahoo.com)

converting liters to cubic inches can be done by multiplying the liters x 61 ...ex: 6.0 liters x 61 = 366 cubic inches - kinda fun to convert old engine sizes to liters as well - just divide the engine size by 61 - so a 409 (she's real fine) would convert to 6.7 litre or a 427 coverts to 7 litres. 289 mustang 4.7 litres. make sense?

what does cc mean for different vehicles

Robert Fogt

cc stands for cubic centimeter which is a unit of volume.

You can convert between cubic centimeter and cubic inches on the volume conversion page.

HP = torque x speed / constant
Torque is a result of displacement and other factors like compression. You can convert metric displacement (liters) to english displacement (cubic inches), but that does not really tell you torque.
Sorry, no direct route between liters and HP.

the engine size cannot be converted directly to horsepower because there are other factors that need to be taken into account (compression ratios, etc) i am just not quite sure what all these factors are..
and alot of hp specs can be found at the maker's websites or sites like cars.com or possibly on kelley blue book

You are right, there are no stupid questions, just stupid people.

Hey, my house is 2,000 sq ft. How many bedrooms does it have? My fathers house is 4,000 sq ft, so it must have twice as many, right? FYI, mine has 4 bedrooms, my fathers has 3. Size does not matter, I'm sure your wife tells you that all time.

Look at this chart about a Chev 5.0L engine.

Year hp lb•ft
1976 140 250 w/2bbl.
1977 145 245 w/2bbl.
1978 140 240 w/2bbl.
1978 160 235 w/4bbl.
1979 130 245 w/2bbl.
1979 125 235 w/2bbl.
1980 155 240 w/4bbl.
1981 150 240 w/4bbl

Over just a couple years the power rating ranged from 125 to 160. Emission standards, fuel system, electronic controls and compression ratio are just a few things that can contribute to power output. Do a Google search for what, specifically, you are looking for. Ex. "HP rating on a 2004 Durango 4.7L" and you will find your answer.

I have a 1991, 88 horsepower, trim motor that I am trying to replace. I have tried two times to get the correct trim motor but I have been sent the same part by two different companies and neither one is correct. I need to know what liter is correct for an 88.

#1 post may be refering to the following... In the UK in 1910, they needed a tax, and the Royal Aoutomobile Club came up with this...
RAC hp = (Dsquared*n)/2.5 where D is the diameter (or bore) of the cylinder in inches, n is the number of cylinders. This is the displacement in cubic inches divided by 10π then divided by the stroke in inches. It gave rise to engines with 'undersquare' dimensions (bore smaller than stroke) this tended to impose an artificially low limit on rotational speed (rpm).
The situation persisted for several generations of four- and six-cylinder British engines: for example, Jaguar's 3.4-litre XK engine of the 1950s had six cylinders with a bore of 83 mm (3.27 in) and a stroke of 106 mm (4.17 in), where most American automakers had long since moved to oversquare (large bore, short stroke) V-8s like the early Chrysler Hemi).
