2000 degrees is safe for a micro-second.
1500 for about .3 seconds.
1250 for about 3-10 seconds, but don't repeat for a few minutes or more, and don't do it often.
1100 for about 15-20 (I'm guessing that's about 1200-1250 chamber temp when measuring post-turbo).
1000 for 30-45.
700-900 for just about however long you want to ride.
Unless you are using waterless coolant, in which case you can up the above times somewhat (waterless apparently doesn't have the hot-spot-flash-point problems of 50-50 coolant mix so it doesn't steam off & allow a really hot area of the casting.
That's my formula, more or less. Heavy heat toll depends, IMO, on duration to allow expansion/contraction which is the maker of fatigue failure of castings, head gaskets, etc. Of course if your drill it good & hot for too long a single stretch, you don't need to wait for fatigue.
