Well the torque/power curves you can find them in the "F1 Challenge 99-01" game....they might not be completly realistic but at least it gives you a small idea....the file that has these are in the car folders....each team has thir own file for the car/engine...just look around.
I know this cause I did a little fiddling with my minardi engine....now it goes to 21000 RPM and has maximum torque an power at all rpm over 6000
