A OM605 for track days / rallying - Whizbang - 10-17-2014
So the question is then, how do i manage EGTs? I see many warnings of "10 - 20 seconds of WOT" causing damage. That obviously wont work for motorsports. What are the ways of mediating this?

Start with sensible hardware. A pump with bigger elements and one of Dieselmeken's fancy ALDA's is a good start. A good sized turbo and adequate intercooling are also on the list.
Once the car is built, identify any weak points through data collection. Weak points could include inadequate intercooling, restrictive intake path, restrictive exhaust manifold or exhaust, hot side too small, etc...
I'll be installing a 14point7 Idash to log wideband O2, 6 egt's, exhaust manifold pressure, intake manifold pressure, oil temp, IAT. That should tell me what I need to know.

What kind of intercooling hardware are you set up with?

I see some melted turbine on a diesel, if it really 1200 degree Celsius I guess we will have another one soon if not all-ready. Modern turbos is to withstand 1050 degress, yet another 150 degrees is much. It is a matter of secunds before something melt. what kind of gauge do you use to measuring 1200 degrees?

I'm using 'defi', 'Greddy' meter to moniter engine condition..
pretty accurate guages.
And i never melted anything but journal bearings
