Really blond question...

Torque - The moment of a force; the measure of a force's tendency to produce torsion and rotation about an axis, equal to the vector product of the radius vector from the axis of rotation to the point of application of the force and the force vector.

BHP - The actual or useful horsepower of an engine, usually determined from the force exerted on a friction brake or dynamometer connected to the drive shaft.

I think torque is how much physical pulling power it has, and bhp is how fast it can make that power,

Something like that, ive heard it soo many times but I still dont really get it.

BHP is power. Torque is twisting effect.

You answered your question yourself.

I never got it either. You need to have some physics knowledge to understand it on any level.

[Nath]

Oh no! Not this question, please


Torque is the force with which your engine turns. The revs are the speed at which it is turning. HorsePower is just a way of expressing the two things together to give a means of comparing engine performances that people can understand.

Imagine (in terms of something more quantifiable than a load of physics) that the BHP can result in a fast vehicle whereas torque will result in a vehicle with grunt (think pulling power, accelerating uphill etc). A diesel's torque is what makes it good for pulling caravans etc, but it'll be sod all use on a race track.

[veeeffarr]

Torque is a measurement of the force exerted when the wheels are twisting.

BHP is how hard it 'pulls'.

I still dont

[cagiva gezzer]

Torque is how hard you can punch, power is how many times you can punch in a given time.

You use torque to open a jam jar lid.

You use horsepower to pull the jar across the table.

[colin1]

work done = force x distance
work done = torque x revolutions

power = (work done / time)

(work done/ time ) = torque x rev/time

power = torque x rpm x constant of proportionality

so the higher the torque or the rpm, or both, the higher the power (bhp)

Torque is some crappy bike film. BHP is a bike accessory place.

[lilredmachine]

Jap performance cars, such as the Integra Type-r can get away with having 200 HP and about 130lb/ft of torque (despite the small amount of torque, a large amount of horsepower is produced due to the amazing speed with which the motors spin) as they weigh very little and are made out of cardboard and held together with chewing gum. If you tried the same thing in the Buick getting on for 2.5 tons, it just wouldn't go anywhere, so has 500 Lb/ft of torque compare to only 400 hp.

torque is more important then, as far as we are concerned.

Now thats all as clear as mud, its time to chuck a little something else in to confuse the kids.

When you open the throttle at low revs and the bike picks up lot of power, that is not because it has lots of torque. That is because it has lots of low down power.

Twins do not have more torque than fours, they often have less. They do however generally have more low down and midrange power. They are producing more torque at lower revs, whereas the fours tend to pick it up later on.

Still not a clue? Torque is a good thing, you like to have it.

[Suzuki]

Here's another example.

Go to a hinged door in your house.

Put your finger near the hinge, and push.

Your finger/arm/etc is the engine, the door is the chain/sprockets/wheel. You can imagine the edge of the door (with the handle and lock) as the outside edge of your wheel.

Your arm (engine) provides power, which is converted into torque through the door (chain, sprockets, wheel). Depending on the length of the door and where on the door you push (size of sprockets, wheel, gearing, etc) a different torque is created from the power provided.

The combination of power and torque, gives you the resulting movement of the edge of the door (wheel).

I'm sure that makes it crystal to you all.

Its really hard to explain this, just one of those things to understand.

Ok. Practical example of torque.

If attach a turbocharger to an engine, you are using that turbo in boost torque primarily. The turbo forces in more air, so more fuel can be burnt. More air and fuel gives a bigger bang, this bigger bang is an example of more torque.

The power produced is then torque X revs.
