6.4L Power Stroke Engine and DrivetrainDiscussion of the 6.4L Power Stroke diesel engine and drivetrain in the 2008 Super-Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Local dealer had one, and being that he's my friend he let me check it out. Man they are quiet. So much much more quiet than my 6.0, and I thought that was quiet. Its hard to describe, its as quiet as a gasser with a slight diesel sound.
I would prefer more diesel noise, but I suppose thats the way the market is going [img]/ubbthreads/images/graemlins/mad.gif[/img]
The one thing I was dissapointed about was that I thought it was supposed to be a "new" Super Duty. It's more of just a refresh... New grill, headlights, tailgate step(whoopdy doo)
There must be a few of them getting out now. I heard one today also. Sounded just like the D-Max to me. Bares absolutely NO resemblance to any International diesel engine I have ever heard. None, nada. I sorta liked it. I could not get them to spool it up.
I was just reading the new Diesel Power mag, test on the f-450, sucker runs 42psi boost and the turbos are sequential Borg Warners. Siemens common rail, 6-hole piezo injectors.

<font color="blue"> First of all, this post is not intended to be taken as I am saying they are gonna fail, rather I would like to know what Ford came up with to keep headgaskets from blowing. Anyone know? I would say that boost was a HG killer on some 6.0Ls, but there are a lot of other factors that are associated with that (head and deck surface, combustion temps, actual boost pressure, CP, etc.) also. The reason I ask is because the 6.0L boost levels are usually around 29-33, maybe 34, but these 6.4s will be running the same boost levels as Top Fuel dragsters. There has to be something if Ford thinks they can control this amount of pressure. Can you effectively add boost and power while keeping CPs in check? Seems to me that the most available power will be from the highest CP you can safely achieve.

larger headbolts and multi-layered steel head gaskets.

16mm headbolts for the 6.4L they are larger. Multi-layer head gaskets, beefed up material on the heads themselfs, stronger internals, they say only the camshaft is left from the 6.0.

It's still the same old 1998 truck on the outside, and that's where they really needed to update.
I like the new truck, but they should have changed up the sheet metal.
