REAL 3.5 VS. 5.0 power curves

Now THAT would be killer! And I wonder how many who bash EB's for turbo reliability would buy one... lol It wouldn't surprise me if sometime in the future there's a 4.something EB that replaces the 5.0, but who knows. EB's have been the biggest sellers for a while now, but I think Ford would find it hard to get rid of a NA V8 without getting lots of negative feedback from a percentage of owners. It would be a big gamble for sure, hoping that most just accept it and don't just switch brands.
I know plenty of people who will not buy an EB F150 due to some perception that there are significant issues with the engines. I've told them all that that is not the case but they insist that I am wrong.
Shhh...the 2018 5.0 beats both EB's...

Well shoot, I really wish I would have been told the real story before I ordered my truck. With this one post, my world has come crashing down around me and all the knowledge I gained has just gone. I mean, really, why couldn't have I run across a single chart like this when I was doing my research?

The stupid thing is 2015rubyFX4 just wants the 5.0 to be top dog in the truck motors and it's not. That in no way means it's not a great motor, it's just not the most powerful truck motor. There isn't a bad motor in the lineup and every motor has a fan base for various reasons. Enjoy what you purchased. End of story.

Exactly, the eb had not enough torque at 1000 rpm to graph and at 2000 rpm the 5.0 was 200 ft lbs more then the 3.5. In fact the 3.5 did not catch the 5.0 till 2700 rpm.. Oh and BTW Its not my graph, Im just reading it like you are. Someone else posted it

It's not how it works. Have you personally spent time working with a dyno? I have. They started the recording at 2k RPMs on the 3.5EB. It takes time for the dyno to ramp up and show the torque curve. All you are seeing here is the equipment delay and ramp up from the point it was turned on. Basically, it was a bad run or they were for this particular run were only interested in the power curve after 2k RPMs. But whatever the reason for this chart it is comparing apples and oranges. Now give it a rest. And why do you care so much? You like the 5.0 in your truck, that should be the end of the discussion.

I said it earlier and I'll say it again, its almost impossible to dyno an engine with an automatic transmission below 3000 rpm's. The transmission just downshifts.

That may be true. I have dynoed numerous times my motorcycle engine builds, no matter where we started the runs I always see a ramp up curve. I’m not an expert at it, just done it bunch of times and worked with the dyno techs looking at my power curves.
