So what would happen if.....
Discussion
You had a car with 1000ft/lb of torque but only 5bhp; equally what would happen if you had 1000bhp but only 5ft/lb of torque. Now i understand the principal of both torque and bhp, and i know to achieve these sort of figures is probably impossible due to friction etcetra... However someone just explain this a little for me, my sleep starved brain is chomping on it.....

the 1000ft/lb would produce its 5bhp quicker than Vixpy relieving himself over some tottie, Gwiz
and the 5ft/lb would takes years of building up to create its 1000bhp....
..i think....

I think I've got it,
Cheers all, I can go to sleep now.

The first would move very, very slowly but be able to tow a small house. The second would spin very fast, but not be able to push it's own weight along.
Another way to think about it. Think of a big f
kin flywheel like you got on the old industrial engines, 12ft in diameter of cast iron turning at 100 rpm If you try to grab onto it to stop it, you'll get catapulted onto the nearest roof.
If you took a scalextric car motor, it may be spinning very fast, (for the sake of the example, 5000 rpm) but you can stop it by putting your finger on one of the wheels.
Power is the amount of work done IN A SET TIME
So the amount of work done (i.e. the force produced, which is torque in this case) multiplied by the RPM (How quickly it's making that force) is power.

Simples - Torque is how much a motor can pull, and horsepower is how fast it can do it.
If you have ever taken a few large friends in your car and noticed its not quite as quick as it was - low torque.
Power boats have 2 or 3 250hp outboards - this doesnt mean its a 750hp boat - it means it could take 3 times the weight or 3 times the current and still travel at the same speed.
