RAM EcoDiesel a Flop for Towing

No one disputes that the EB is more powerful but you are asking me to believe that it can handle nearly 40% more heat in 17% less time than the ED and not be more stressed. I don't think so.

Where are you seeing that the Ecoboost is running 40% hotter? So basically what you are saying is that the Ecodiesel is not designed to handle the stress of a diesel?

Regarding boost pressure which which you continue to bring up. As any diesel guy should know, diesels do not run fixed fuel air ratios like gas engines. It doesn't matter how much air you stuff into a diesel, if no more fuel is added no more heat (or power) is produced. It just isn't possible because the energy isn't there. Higher boost pressures in diesels with no fuel increase result in lower exhaust temperatures and put less stress on the engine, not more. If you have a diesel that is running high EGT's, stick a bigger turbo on it without increasing fuel flow and bingo, temperatures go down.

Yes I know this but what does it have to do wh
Ith what we are talking about. Are you just mad because the Ecoboost creates more power?

Regarding your claim that the ED is running at 90% of its maximum RPM to produce peak HP. It's redline is 4800 RPM and peak HP is 3600. My calculator says that is 75% of peak RPM.

That 4,800 rpm you are reading is the static rpm limit like most if not all vehicles that have a higher rev limit when not in drive. The max usable rpm in the Ecodiesel in gear is 4,000 rpm. Go ahead try and put that Ecodiesel in gear and tell me what max rpm you can hit. It will NOT be 4,800 rpm so why would you count rpms you cannot use?

In contrast, your 6.7 Cummins has a redline of 3500 RPM and makes peak power at 2800 RPM or 80% of peak RPM.

Again, that is max rev limit when not in gear. My max usable rpm is 3,000 rpm. I will bet you $100,000 that you will not be able to get my Cummins up to 3,500 rpm in stock form when in gear and that is a fact. You have yourself a nice day as well.
