EPR JT9D-7A
 
Hello,
I am a true lover of b747-100.
And 'possible to find somewhere an approximate correspondence between EPR and N1 motor JT9D-seventh? The values that I care about most are: EPR 1.10 EPR 25.1, EPR 1.40 EPR 1.55.
I know that the correspondence between N1 and EPR is not constant but depends on environmental factors, but I want to average values. Can you help me?
