Only 10HP more?

I don't understand why the expectation of a lot more hp. The main update is dual injection which makes for more precise fuel delivery for wider spectrum of conditions. The geometry (bore x stroke, etc) and most of the internals have not changed, and the 5.0 is not having force induction, so it will not magically pump more air and makes a lot more power.

So the 2018 5.0 has an inter cooler now? If not, then isn't it pumping the same amount of oxygen per cycle?

I was wondering if the changes to the V8 might be enough to warrant a test drive and consider upgrading. If these numbers are accurate, it's not even worth a second thought. I also see that they're positioning both EB engines to tred on the V8s numbers now. Looks to me like one step closer to Ford phasing out the V8 option.

Because they cannot get a small NA 5.0 to make more power on 87 octane without sacrificing necessary low end torque. Trucks are not Mustangs-they're much heavier and have to be able to haul and tow stuff. However with DI, I still would've expected a 25+ hp bump.

Uh, no...direct injection allows for higher compression. Higher compression makes more power, more torque, and has higher fuel efficiency without sacrificing low-end. Higher compression also makes more power and torque without needing additional fuel. Basically, it improves all aspects of operation except detonation resistance, which the direct injection takes care of. Ford left a lot on the table here, folks.

So the 2018 5.0 has new piston? Otherwise I don't see how the compression went higher with the same components and same bore x stroke.
