I build my own engine but I don't do it for a living. Before I started doing pools I was planning on opening a shop similar to the ones I had been working at and bought a Land and Sea dyno; plans changed and I have never even taken it out of the crates. Now that I think about this it pisses me off and depresses me, I've had this thing for going on fifteen years now.Magnus, I am your father. You need to ask your mother about a man named Calvin Klein.

First off, I don't even own a diesel powered vehicle, so I don't care about tuners, dyno runs, rolling coal, tractor pulls, etc. My work in the industry right now is supporting a fuel producer which means I work with the big engine OEMs, regulators who get to decide how many more years we all get to have diesel engines, the industry groups working to keep HD diesel alive and fend off electric/CNG/LNG/hydrogen, etc. I feel like anything I say (knowing I care about staying inside that 'legal' box) could just as easily be countered by someone who doesn't give a shit and just wants to make dyno pulls.
Example:

So for anyone who wants some light reading, here's an 80 page paper called Fundamentals of Diesel Engine Technology. Written in 1988 by a guy at Cummins (who is now one of the top researchers and advisors at Southwest Research Institute, one of the best engine labs in the world), this is the first thing I read when I started my internship at Cummins 13 years ago. I put it in my Google Drive folder so let me know if the link doesn't work: https://drive.google.com/file/d/11ly...ew?usp=sharing
As for the fuel vs boost shit, I think you guys are just talking past each other, because we all know damn well that everything has to play well together and be tuned in proportion.
Yes, increasing boost will lower EGTs, but that will also increase charge air temp... increased charge air temp can adversely affect EGT, emissions, etc. There are tradeoffs everywhere.Last edited by Strychnine; 02-24-2019, 12:12 AM.

Example:
Depends who you ask and what part of the power band / duty cycle you're talking about. At low speed, high load valves are a secondary concern... if smoke is a concern... which it isn't if you're just going full-retard.
