So if im not wrong, u mean to say that in BR 211 when u reach 3900 RPM which is going to be its maximum limit and it is rated at 100%, but due to some variables it sometime cross this limit. Correct me if im wrong does this mean that this engine is overpowered and when the conditions are not right e.g Higher outside air temp or some other variable in that case we will get its rated 100% N1 RPM atleast.............
Thanx
