WOW! Talk about a blast from the past!
Not sure the 6.0 was designed with EGR in mind.
Don't know about Duramaxes but you can't hear **** within 20 feet of my truck. I don't think it's quieter than the 7.3 either.
I forgot all about the cackle issue. I recall some 7.3 guys that were very upset over this.
Jokes aside I'm still happy with my 6.0.
(3) the second generation injectors will be smaller, more compact, more versatile and cheaper to manufacture; (4) more power -- the initial offering will be rated at 325 HP @ 3600 RPM (I'm not sure about that RPM) and 550 ft. lb. of torque @ 2000 RPM; (5) this new engine will be quieter than the Duramax.
We are using a variable rate turbocharger that has the capability of compressing more air at lower engine speeds then slowing down at higher speeds or loads eliminating some of the turbo lag on the lower end and the need for a waste gate on the higher end. They've engineered something new for the high pressure oil rails to abate the clatter (no more cackle).
This is going to give us a good foundation to build on for the future. Frankly, I would have been happier if they would have made it an over head cam engine instead of a push rod engine but from what I've seen, it seems to be a very nice package. We had one in an Excursion at the plant -- quiet. I didn't get to drive it and haven't seen the power curves from the dyno yet but suffice it to say, I'm impressed and I'm normally very skeptical.

FYI
The 2003 models with the pilot injection were very quiet, then they reflashed them and took the pilot injection away. I know I had one of the very first ones to hit the local lot.
What was I thinking?????
