GM says 1425 for less than 5 minutes, and 1350 sustained, IIRC. Many of us have hundreds of 1/4mi passes over 1600 deg though. A 1/4 mi pass gets the EGT's over 1600 for about 6 seconds or less. The charger parts take awhile to absorb the heat. If you sustained 1600 for a minute or more, I imagine it would start to damage the charger.
