Thass the torque as opposed to horsepower thing again - it'll do 30 up a hill in 4th whether it's got a 4 ton tow or frankie dettori drivin with an empty tank! Dint matter what the load is, 30 up a hill in 4th is good goin!

Indeed, I was just really just commenting on what Griff was saying - that his N/A is capable - depends what sort of state its in of course.
 
If you want torque at low rpm look at the numbers for the old 6 cyl 2,6 IOE . all down to the stroke . :D
 
I had a long and very drunken late night discusson with a mate recently about the term "horsepower" and we came to the conclusion that it's a really silly and pointless term. It gives the impression that it has something to do with a car's power - being whisky-fuelled we came to the conclusion that if it were really derived from "the power of a horse", that would be its strength, which is effectively its ability to pull, which all depends on its ability to rotate its legs around the hip and shoulder joints - power to rotate would of course be measured in nm or lbft thus a horses power is actually torque!

The next morning with sore heads we decided that we had decided that a horsepower was a pretty pointless term in car speak - it ain't what it's got, it's how it puts em down!

'Mazin how whisky helps put these knowledgeable scientists right!
 
dunt seem to be much difference between a drunk oddone and a sober oddone.

The term "horsepower" was coined by the engineer James Watt in 1782 while working in the performance of steam engines. This occurred while using a mine pony to lift coal out of a coal mine. He conceived the idea of defining the power exerted by these animals to accomplish this work. He found that, on the average, a mine horse could pull (lift by means of a pulley) 22,000 foot-pounds per minute. Rather than call this "pony" power, he increased these test results by 50 percent, and called it horsepower i.e. 33,000 foot-pounds of work per minute.
 
not quite, to be a daft it has to be un-understandable splurge. this on the other hand is easy to get a grasp of, and it also was quicker than writing it oot me self.
 
Accordin' tae "The Scots Dialect Dictionary".....
'Daft' adj 1. mentaly deranged.
2. delirious
3. silly,foolish
4. giddy, thoughtless
5. innocently merry.
6. excessively merry
7. playfull
8.extremely fond of and eager to obtain
9. doting

The sober OD is slightly more able to listen to reason, the drunk one is just always right!

So horsepower is measured in lb/ft huh??? That horsepower described in that wilkipedia (or whatever) quote is pretty much Torque and not the horsepower which is "useful" (to the boy racers) in describing their engine power! ??:confused: At least it has a reference to the power of a horse!
 
power is the rate of doing work - e.g. lb ft per second
torque is a measure of how much angular force is applied (e.g. lb ft) but has no reference to time or rate.
 
So torque is like horsepower per second??? Then why can a high horsepower engine have low torque and vice versa if they are not proportionate or related???

This sounds familiar - might have to get the bottle out to continue this to a the end!!! :)
 
To put it in a simple sort of way, torque is how big your hammer is , horsepower is how quickly you can hit with it :cool: :D

so, Slob, if yu cant understand it - its daft - if yu can, its helpful, thats a bit one-sided, in tit?

see yer getting confused between something that is DAFT and something that is A DAFT

like Mr B Ecclescake of F1 fame, is BERNIE whereas a bung of 1million is A BERNIE.

something that makes no sense is DAFT whereas something that is a load of techical hogwash that only folk that work with the subject matter can understand and is full of big subject related wurds that yer layman finds hard to grasp wtf its all about is A DAFT.
is it clear now or are you still confused as to the difference between DAFT and A DAFT
 
What a mess.

Torque is a force trying to rotate a shaft against a resistance.
The shaft may be stationary or rotating.

If the shaft is being torqued but is not turning, no power is being delivered as no work is being done.


If the shaft is turning AND torque is being applied (like a prop-shaft when driving up a hill), work is being done, and can be measured as POWER, the units being horse-power.

For any given amount of torque applied to a shaft, the faster the shaft is turning so the more POWER is being delivered.

The formula for power and torque is

Torque (in INCH-pounds force) = (horsepower x 63025) divided by the RPM of the shaft

So back to basics, if torque is the force rotating against the shaft, the force coming from the horses muscles and the shaft being its leg, why is the power of a horse called Torque and the work rate it is achieving is called horsepower???

The "discussion" was not so much about what it is, it was about why it's called that and whether it really is a useful term for the boy racers to be using to compare the pulling power of their chavrolets!
 
Horsepower came from the notional description as the amount of work a horse say pulling a plough could do in a given amount of time say 1 hour
Torque was a term used to describe a turning force of a given weight oprating at a given distance from a point this was nothing to do with a horse or horse power untill someone came up with a formula to relate the two.:confused:
They could have called it balesofhaypower if they had wanted to describe it a bit earlier in the chain before it was converted by the horse:D

Re the chavrolets maybe they ought to rename it a ''bling'' the amount of chrome that can be moved divided by the watts of the speakers :cool:
