I'll have to contradict Dar's comments as well. The link below will take you to a number of graphs for different engines but the most telling one is the last one for a YS 120SF although the first one for a Hanno Special also shows how nitro affects the curves. The graphs are all done in German but post #4 has a translation for the terms. Note that torque, HP etc are in metrics.
