I meant Clarkeson has probably not got a clue. As if I would ever slag orf a fellow FM.

Wait a minute, I thought FM was short for "Flippin' Magic", or something like that.

I've often wondered about this one.  Would it be fair to say that if you imagine the axel as a bar rather than an rod, which was moving in a straight line rather than rotating, torque of the axel would be comparible to force exerted by the end of the bar on an object in it's way?

Sorry if that's a convoluted description of what I mean!

Crudely speaking, the max power from an engine is limited by the cylinder volume (all other things being equal)

Well yes, if you only keep one thing variable and the rest constant then the variable item will be the limiter.  If you kept the fuel injection variable and everything else constant then the amount of fuel injected would be the limiting factor.

What I wrote was over simplified - I meant that the power available would be proportional to volume (v. obvious, really) in that it represents the amount of air / fuel that can be burned each cycle. However, the torque characteristic can be affected by piston area and allows higher torque at higher revs (which actually implies more power too??), possibly because of the possibility of bigger valves.
It's too complicated for generalisations I expect. But when has that got in the way of a good forum topic?

Yeah I know, I was just being pedantic  []
