MMR Dissects the new 2018 5.0 Direct Injection engine

2D bar code on the rod bearing? Is that a normal thing to see on these?

The inability to pretty up the valve covers make baby kittens cry.

Direct injection pump runs off camshaft?? Even more strain on the crank sprocket???

That's pretty common.

Yeah, pretty much every DI system(including most automotive diesels) run the HPFP off a camshaft.

Pretty soon there will be another RECALL,crank sprocket will end up just like the half shafts,bang and in pieces.:doh:

Gears need to be fixed.
Rods look weak for boosted applications.

The fact that upgraded opg and timing gears aren't offered in a performance pack is beyond me. That's just extra profits left on the table for the aftermarket to capitalize on. The rods are actually stronger than those of the second gen.

I wonder how the, for lack of a better term, "spray-in-liners" on the cylinders will hold up on boosted applications?

My guess is, not very well. Will this be the Achilles heel of the 2018 Coyote engine for boost loving peeps? There is no way I would run this engine with any boosted application without sending the block out to have it sleeved.

That block is only as strong as the cylinder liners, and quite frankly, those scare the schiznit outta me. Time will tell.

You couldn't be more wrong. The spray in lines are actually significantly stronger than sleeves. They also allow more room for cooling around the cylinders.

That's what MMR is for.

[MENTION=10628]Mod Mustang Racing[/MENTION] any pics of the intake? If not, opinions on it? Heard it was a cross between genII intake and the voodoo intake. Also, you think it would work on the genII? Thank you.

You do know that the Plasma Transfer Wire Arc (PTWA) process was used in the supercharged '11-'14 GT500 cars, right? ...and that Nissan pays a license to use it in the GTR engine as well?

Your fears are groundless.

The rods are actually stronger than those of the second gen.

Where did you get that info from?

If I recall it's the same liners used in the 2013-2014 GT500 and 2015+ GT350. So considering the fact it's been used in a boosted application from the same manufacturer it should be fine for boosted applications.

I watched a video recently in which a senior FORD engineer talked about the "spray in liners" and of how they were new to the third gen Coyote motors. Also, the pics showing the bores of the gen 3 above clearly indicate the liners, if we can even call them that, are paper thin at best, and much, much thinner than the gen 2 Coyote engines.

I could be way, way wrong. I am not an engineer but I have worked on a bunch of Japanese motorcycle engines with Nikasil cylinder bore coatings, and the pics above look just like a Nikasil cylinder coating and not an actual steel sleeve that has been pressed into an aluminum block.

A small company developed that plasma arc transfer technology. Ford bought it and figured out how to apply it to a cylinder wall. It was originally only able to be applied to a flat surface.

Hmmm, that injection system looks familiar.
