Safe MAX Pre-Turbo most say is 1250, the melting point of aluminum is 1220.58° (just googled it) so a quick burst of over that won't hurt. Post turbo is 900 I think, although MOST recommend monitoring Pre-Turbo, More accurate

I'd rather have the more accurate reading Pre-Turbo... Besides, IF it does take out turbo.... another reason to get a D66

For the OP temps in the manifold 1250, over that for short bursts like the 1/4 mile, truck pulls, passing that Cummins or Dmax. But be warned damage won't occur from one time but many times over WILL crack pistons

I should have "to the OP (Original poster), manifold temps max is 1250....."
1250 is the max temps preturbo except for short burst. Short bursts are ok because air temp doesn't mean piston temp, air flow, fuel injection and piston cooling also come into account.
Post turbo temps....I don't think there is any safe temp. I don't feel it is safe to have the pyrometer post turbo as the link in my last post shows. The temp drop across the turbo changes constantly.
