Current Topic:
Old motor efficiencies

What kind of efficiency can one expect from a 150HP motor that is 25-30 years old.  I'm looking for what the motor would have been capable of when it was new, not what it is now after years of operation.  I'm attempting to justify replacing some motors, and need the efficiency numbers (or at ones that are in the ballpark) to figure it out.
