RAM EcoDiesel a Flop for Towing

What is about the statement "Interestingly, the new SAE standard is closer to the European procedure, which is EEC 80/1269. There are minor differences. For example, the exhaust configuration and the specified fuel-quality requirements vary, and these can have an effect on horsepower. But we're talking about small differences, possibly accounting for a less-than-one-percent variation."
in the C&D article that you don't understand.

And what part of "Not all European countries use the same method or same standard" that you don't understand?

Weren't you the one who stated the ED had the higher compression ratio. Improving flow and cooling the intake charge are just other methods of raising manifold pressure.

Yes I did. The Ecoboost has a compression ratio of 10:1 with a while the Ecodiesel is a compression ratio of 16.5:1, but what does that have to do with your initial statement of how you think the 2.7L Ecoboost is more stress since it makes more power?

Again, I don't see what that has to do with your initial argument that since the Ecoboost is making more power then it is more stressed.

In previous posts you made reference to the ED screaming away at 3500 to 4000 RPM when the presenters clearly said it didn't go above 3500 RPM.

For good reason, it makes peak HP at 3600 RPM

3.0 Ecodiesel Peak HP at 3600 RPM. Peak torque at 2000 RPM

2.7 Ecoboost Peak HP at 5750 RPM. Peak Torque at 3000 RPM

I can't imagine why I would think something so ridiculous.:R

What does it matter about peak when the Ecoboost did not run at its peak hp rpm in the videos? The Ecodiesel had to run at its peak rom for power while the Ecoboost was far from it. So yes, your theory that just because the Ecoboost makes more peak power then it was more stressed going up the hill is flawed and yes the Ecodiesel struggled to keep the speed limit going up that hill. Also, the twin turbocharged (one for each cylinder bank) 2.7L Ecoboost has a max boost of 12 psi while the Ecodiesel has a single turbocharger that has been known to commonly see 23 psi from owners in the forums although a a max is not known.
