1200 is a good number. When the 'push the boundary mob' try a little higher, they can get all excited & crow about it when they dont melt a piston. The EGT does not give the actual temp that is seen in the combustion zone in the motor. Long running at 1200 like for an hour could still damage a piston. MB destroyed many N/A motors with turbos in testing before the turbo motor emerged. There is a detailed report by them about it. If you put a big load behind a 616 with a turbo & so load it right up, expect trouble.
