I would have to look that up to be quite honest, engine out acceleration is presented by our performance program, it does depend on aircraft variant and conditions, and since i am now on the A320 family it won't be of much use i guess. The normal acceleration altitude to the west (26) is 10.000ft and to the east 7.000ft. But since we are speed limited to 165 kts throughout the turn, acceleration will take place earliest after we are out of the turn anyway.
