Default Determining safe EGT for your motor?

Is there a way to determine what the maximum safe EGT temp is for your specific motor? Everyone has different tuning, slightly different probe mounting points etc. I've done some searches and the consensus seems to be 1600F is the magic maximum number. My car will reach 1700F in a 5th gear WOT run. My probe is installed in the front passenger side runner in the manifold. I'm wondering if there is a way using data logging to determine if 1700F on my Defi gauge is actually safe for my motor?

If there were a specific test, it would be destructive. The 1600 number you have is the lore. RiftsWRX, I believe, has run his own car to 1700 for many miles of hard driving. It's the valves you have to worry about. I kind of remember Jorge being of the mind that less timing gets the heat out of the cylinder faster--reducing knock initiation, but at slightly higher EGT.

I bumped my warning up to 1700 per Jorge's advice but I saw 1800 on a pull once. I was just wondering what other variables are in play. I guess you're right that a test of the max limits would be destructive. The car still seems happy even after seeing 1800. What makes me nervous are all the 1600s being thrown around. I was thinking 1600F may be the temp that stuff starts melting or something.. =P But like I said, my car sees 1700 on 5th gear pulls and it's fine. So something to keep in mind for future people looking for the magic EGT number.
