when you guys are talking about maximu egt temps, are you talking in C or F? i ask, because on my turbo cars, i can run up to 1650F for bursts or almost 900C.

here, i see everyone talking about keeping under 1250 or so....

i thought our cummins' could handle more abuse than a gas engine so i was initially thinking degrees C, but that's really high in F, so i'm confused. our pistons will melt at a lower temp than a gas engine?

the obvious answer is that the 1250 is in degrees F, but why so low? that's just barely starting to warm up in my Talon...

Yes, the diesels have different materials...remember that they have to withstand cylinder pressures that most gassers couldn't dream of. And because of this, they have to use stronger materials that have lower melting points...

Another reason for this is that we work these trucks.. For drag racing where you are only at those temps for a few seconds is not bad.. But when you put 20k lbs behind them and towe across the country then it will become a bad thing very quickly....

for short distance i have seen quite a few with 1500-1700* F in the CTD but as a rule for longer distance don't go over 1250* F allthough i have a friend with a 95 12V that ran his truck pedal to the medal for almost 5 miles and his gauge stopped at 2,000* and it went past that now the side of his block looks like a manifold,i wouldn't do that but i have had my Duramax to 1800* F for a very short distance..

I have bumped 1700(F) with mine. It was only for a few seconds, but it hit it! The norm running empty seems to be around 900 - 1000 bumping up to 1400 during regen on this 6.7. Figure I'll run it till it blows, or the computer safety shutdown kicks in.
