If the EGT is over 700 degrees C on a shutdown engine I would suggest you have a bigger problem than not being able to start it.
Can anybody provide a manufacturer reference for this minimum engine rest phenomenon? A reference with the stated EGT would be appreciated.
Yes I agree that you would have a bigger problem. Nevertheless, the limits are there. Granted, most likely not a limitation on your typical turnaround.
FCOMs are proprietary but here's an older 330 FCOM. The EGT limits for this particular variant are on page 100. http://www.avialogs.com/en/aircraft/europe-and-consortiums/airbus/a330/airbus-330-fcom-flight-operations-volume-3.html#download
Some Engnes are subject to a "Bowed Shaft" situation after shutdown until the Engine residual Temperature drops.
The engine makers used software to modify the starting Sequence to put cooling air through the engine before adding Fuel to normalize the Engine before adding fuel and ignition..
