Want '74 2.7S graph, info & comments
 

Does anybody have the factory rpm/torque and rpm/hp graph for a '74 2.7S (Euro)? I've seen a number of graphs that are supposedly copied from the original, but they are vague. Is it perhaps in the '74 owner's manual? If so, can somebody please post a scanned pic of it?

Also, my '74 2.7S runs out of steam at about 5500rpm. Don't get me wrong, it pulls hard all the way, but it seems to peak low, at about 5200rpm. Sure it will do 6000rpm, but it doesn't rev like a 2.2E, for example.
What are the characteristics of other owners' 2.7S cars? Is this how it is supposed to be?

The CIS torque and power curves are much closer to 'T' characteristics than an 'E' MFI engine!

Early_S_Man, where on earth do you get all the info? Do you live inside the Porsche museum? Thanks a lot for the graph.
