Smarty can fix that

 

don't worry!?!? ulsd and a dpf are some of the things that make us 5.9 guys worry the most!

 

Ehhhh not to worked up on an 8,6 works fine for me and my MPG is fine no complaints on it.

As for wanting a 3 ton diesel truck to run like a Mustang GT I'll pass if I want fast there are other things I would look at.

Just talked to some cummins engineers the other night. The new 5.0L v8 engine is a 4 valve-per-cyliner and DOHC with tein superchargers in the valley. He says the 5000rpm redline is due to using the cutting edge technology to squeeze all the power out of that diesel. Yes the durability will be of the 5.9L time.

[I]ULSD (Ultra-Low Sulphur Diesel)
Anything over 15ppm sulphur content will ruin the new Cummins V-engines. QUOTE]

I was just yesterday talking to a fellow at the truck stop that knows of a guy who put "farm diesel" in his new 6.7L CTD and totally ruined the motor. It cost him $12K at Dodge to replace the entire thing. I don't know what some people are thinking about.

 

A V8 won't have the efficency of an inline 6, but thats not the issue at hand. Putting a straight six in the half ton would add weight, versus that of the V8. Second, in the V8 config, it'll go in a van without problem.

As to power, diesels, as we know, need only hav enough air to burn whatever amount of fuel injected. So long as the oxygen can be had to support combustion, you can burn any amount of fuel.


And this explains why... "supercharger(s)" will definitely help in making gobs of power. Also, having a high redline is key to HP. If:

hp = T(ftlbs) x RPM / 5252

then more RPM = more HP

Thus, any design parameter that allows more RPM without burning more fuel means "free" hp.

At 5.0 litres, (taking a page from gasoline history) a V8 could go with 4" bore by a 3" stroke. That means easy revs because of a short stroke. It also means that the rod can be beefed up to hold up to the diesel compression ratio without massive concerns to rotational weight OR power loss due to inertial forces created in the reciprocating motion.

It could well be that, like the Ford 5.0 V8, the Cummins 5.0 V8 is far more than the sum of its parts.

Time will tell.

 

For a half ton pickup a V8 diesel would be fine imo if you need to hook to something heavy that's what the HD truck is for. Just the fact that it's a diesel will have me looking at the diesel F150's and Ram 1500's when they hit the lots in mid 08. I'd rather have a diesel in anything I drove be it a compact car or whatever. On another note I think the Ford 1/2 ton diesel engine is engineered and built by Ford alone and not International. Which caused a major lawsuit to be filed and started some bad blood between the two companies.

 

The bad blood was caused by the POS PSD. Its anyones guess what caused the new diesel to be a POS, but Navistar says its Ford's engine management, while Ford says the design was flawed before they got it.

So at some point, Ford stopped paying Navistar, and in return, Navistar stopped shipping engines. Then word leaked out that Ford had an in house design coming up.

Both companies are going to lose face, but Ford will be hammered by this, while Navistar will simply carry on.

 

I forgot about that but there was also a lawsuit filed by Navistar/Intnl over Ford engineering, developing, and testing it's own diesel engine for a half ton pickup that I read about in some press releases somewhere. I'm not certain if this engine is in the new diesel F150 or if it ever got past experimental pre-production stage (info is so sketchy on these new 1/2 ton diesel engines) but I do know they were working on one independently and Navistar saw this as in violation of their contractual agreements..
