While I was in school today, I was wondering, how can the engine be at 18,000RPMS!?!? Thats so fast, its unimaginable.
Well, F1 teams have a virtually unlimited budget for an engine, so it's simply a case of the best engineers working with the best materials at some of the best facilities in the world. They get to spend gross amounts of cash on minute details. Then there's the fact that an F1-engine only has to last an exact number of laps.
It's still hard to grasp, 800hp from an atmosferic 3 liter engine.
I'm sure none of the F1 teams wanna reveal true numbers for their engines, but what do you think the power output is like? BHP is around 800 but what about torque? That's a 3.0L V10 engine.
I think the torque figures might be dissapointing, since there is only so much air you can get into a small atmosferic engine, and thus so much fuel to burn.
Suppose the engine is engineered so well that at one particular stroke, 3 litres of air make it into the cylinders before the inlet valves close (I know this sounds dodgy, I actually mean: the amount of air in 3 litres at atmosferic pressure) . The air/fuel weight ratio for best performance is a fixed 12,6 to 1, so the amount of fuel that can be burned is also limited, hence: the specific torque per liter output of an engine is also limited.
I know, in real life it might be possible to achieve more than 100% volumetric efficiency (by getting the air to compress into the engine with a trick inlet, or whatever), but it's never going to be more than say 130%. An F1-engine gets its power from MAD revs.
If you know the power output at a specific engine speeds you can simply calculate the amount of torque, since torque, engine speed and power have a fixed relation. I'm not an engine builder or rocket scientist, so if I'm overlooking something, by all means say so
