As it is now, firewalling the thrust levers if ground contact is imminent is a recommended Boeing procedure and thus practiced in the simulator with no apparent adverse indications.
Obviously it is better to damage engines than totally destroying the aircraft and kill all onboard no?
On the NG,There are no EGT temp protection inflight just N2 overspeed protection via the EEC and an overspeed governor.
I doubt the classic would be otherwise.
There is no mention in Boeing publications warning of this overtemp danger if the thrust levers are firewalled in an emergency
Pretty sure Boeing doesnt want pilots 'worrying' of possible overtemping the engines if firewall is necessary...
If in fact overtemping is likely to occur during a go-around, one would think this should be incorporated in simulator design?
It should not if your crews know the GA limit and do their job /sops properly and or use the AT arm mode..
I would think your airline trainers would have sufficient knowledge to teach/explain the negatives in firewalling 'systematically' and even over thrusting the thrust levers during standard go arounds...
I tried a discussion about this in thread about the autothrottle...but the temp /over thrust issue didnt seem to bother anyone at the time...
Good luck...
