This is why cars with low torque make their power in high revs...Ferrari 360 is quite low on torque so makes peak power up near 8000 / 9000 rpm, i.e. you need the torque figure X many more revs to get a big number....same on a sports bike.
Cars with low down, high torque don't need massive revs for the power output and the design of a high torque engine tends not to rev as much.
I wouldn't say the 360 has bad torque for a N/A engine.
I believe the reason Diesel's cannot match an equivalent petrol in power is because they can't rev high (due to their construction). RPM increases VE, so will result in more power, all things being equal.

Agreed, also there are poor maps out there that just add boost, without remapped injector timing.
