Hi,
I'm looking for those diagrams, indicating fuel efficiency over torque and reversions, for engines of any type.
Unfortunately I got only 1 hit with google in english. In german pages there were 3 or 4 useful diagrams. Seems to be a big secret, because my E-Mails to several companies were not successful. If anyone can give me links etc. please tell me.
Thanks for your help.
Thomas
