i suppose if they could only rev till 6000rpm, they would.
problem is, they have such a huge rev range, what do we actually
consider high or low? i mean, having the torque pull at 800Nm from
12000 rpms thru to 17000 rpms might seem high, but is considered
low for a F1 engine?
I do suppose the question of how u want to tune your engine depends
on the track. For a track that has a lot of long straights, u would
want to engineer your car for high bhp at high rpms. if it has a
lot more corners, obviously u'd want to engineer it for low end
torque.
another consideration as to how low we should go, is how well the
car can cope with the kind of low end torque as it exits a corner.
if it's going to result in oversteer as it exits, then obviously we
could engineer it for max torque at a slightly higher rpm.
i guess its not easy to put everything into one single
generalization.
