Plugged in the following for a GE CF6-50E2 (51,800lbs rated thrust) 747

BRU RWY 20 +20C QNH1000 5 Tail and 306,000kg

Came out with Max thrust 112.7 %N1

Flap 20

V1 133
VR 144
V2 158

Also allowed for an addition 30,000kg to be carried.

What's the rated thrust of the Pratts fitted to the actual A/C?
