From the XYZ Airline Volume 2.

"The full rated takeoff thrust for the installed engine is available at a thrust lever position less than the forward stop. Fixed or assumed temperature derated takeoff thrust ratings are set at thrust lever positions less than full rated takeoff. If the thrust lever is advanced to the forward stop, the EEC limits thrust to the maximum thrust rating OFFERED for the airplane model

The standard reserve thrust rating available at the forward stop varies according to fleet configuration as follows:

aircraft registrations 1 - CFM56-7B24 rating
aircraft registrations 2 - CFM56-7B27 rating

For those that are not in XYZ Airline, registrations 1 are 700's with a mix of 20k and 22k motors, and registrations 2 are 800's with a mix of 24k and 26k motors.

so to answer the question, firewall the levers in a 700 and you get 24k, in a 800 you get 27k (assuming ISA +15 or less and sea level)

LOKE, I appreciate that this is essentially your post reproduced, however the addition of the two types helps clarify the mystery....

Please don't cite and identify the company ...
