I was talking in terms of per cylinder, not the whole engine.
I should have stated per cylinder but it was late and i should have proof read it really ![]() ![]() A ducati makes more torque per cylinder than an R1 simply because it has larger stroke cylinders. And wouldnt bigger engines have longer strokes, i cant think of any engines that are under square now, and to be practical most engines are in pretty much the same band (ie bore and stroke) for that cylinder size, like a 4 cylinder 600 Hornet will have pretty much the same bore and stroke as a CBR 600 right (i know its the same engine) ? Just as a general question, how can the 3 litre F1 engines rev so high, do they have tiny strokes and massive bores or somethin? |

I don't think we can start complicating matters with discussions on engine design and configuration; then we'll have to start talking about the effects of gearing and so on. We can't generalise, but we can give an idea what the two terms mean, because they're inextricably linked.
However, we can, in simple terms, describe what the two terms mean in the real world. I think that's been done here, so I won't do it again. ![]()

Is frank Bruno twice as strong as Linford Christie. Probably.
So imagine a twin cyl engine (SV) is powered by 2 Big franks and a 4 cyl GSXR is powered by 4 Linfords. The four linfords are are as powerful as the 2 franks and can go faster but have less pushing power. So if your car is being pushed by the 4 linfords they will get a good turn of speed out of it but may struggle to get it moving or push it up a kerb or over a hill. The 2 big Franks will get the car moving easier and hills just wont matter but they are heaveir and slower at the top speed. so thats why you need torque for a good push in any gear and to get you going and move the weight. BUT: once on the go you want power to speed you up and get a good top end. SO if you think about 2 franks or 4 linfords pushing a car from a standing start you will see where the power and the torque each have there own adavantages. Or am I mad. |

Check out the How stuff works site, this page
![]() http://science.howstuffworks.com/fpte.htm Is a good place to start it covers the wider topic of Power, but it deals with torque and has some nice animations Hope it’s of some use for the original posting |

power is power, whether its pushing you up hills or pulling away or speeding you up. A revvy 250bhp engine will go up hills that a 200bhp diesel torque monster won't. The only difference is at what revs the engines would be running at. Just to confuse the matter further a GSXR600 produces more torque than an SV, just at much higher revs ![]()
