sequential single turbo
-
i thought this was interesting. sequential single turbo. it will be interesting to see where this goes. and yes i know, the scorpion isnt new news by anymeans, but i just read this article today. you will have to scroll down the page about half ways or so.
oh and speaking of new diesels, we talked to some of the drivers at the bar the other night that are testing the new heavy duty dodges down here, and the motor that is in them is a NEW cummins, it uses the 6.7 block, but the head is different and it is putting out ~700hp, now thats just what they said, who knows if its true or not, but if it were, my guess is that it wont come out on production with that much power, they are just testing the internals. they said that this motor is about 7 years from production. they didnt say when the truck would be released for sale, but my guess is oct-nov

meh, still will be a wannabe POS PSD
competely stock internal 5.9's with headstuds and gasket have made 800+ all day long
once the aftermarket catches up with the cummins 6.7 and you can get rid of all the emissions and there is some support, what out, because those will be an animal
Its funny, a couple of our new fire trucks have the 6.4....... talk about a fucking powerless POS under the curve.... damn near have to drop the clutch or ride it out to get the trucks going out in the field loaded without killing it

ha yeah but this will be fords first in-house built diesel, nothing to do with navistar at all, but it is ford so im sure they will find a way to ruin it.
yeah i know there are alot of stock, high millage 5.9s runnin around with high hp numbers. in fact my buddies 2000 cummins, with 240000 miles on it, (i know, cummins go way way higher than that for millage) has some pretty decent mods done to it and still no sign of fatigure, besides for the beer can that the motor is wraped in starting to fall apart. hes got quadzilla adrenalin, ats 3 piece manifold, ats intake horn, bd monster stage 1 injection pump, holley black lift pump, afe stage 2 intake box, big valair dual disc clutch, and we just finished up with the set of twins for the truck a couple weeks ago. i dont remember all of the specs of the turbos as fas as inducer, exducer, and exhaust housing go, but the compressors are a 57mm over 78mm, both borg warner.
my dad was looking at buying one of the new 6.4 fords, but i told him just wait for the new body style of the dodge to come out.

Just wondering why the cummins is so simple looking and the Chevy and Ford look like big piles of complicated bull shit?
simple = cheap. i don't even want to know what it would cost to replace the stupid dual comp wheel turbo thing.

for how often diesels have issues with the turbos i would not be looking forward to paying to replace one of those things

.LOL agreed.... Leave it to Ford to put a composite intake on a diesel............... and seriously i have see it all when one of these is on a diesel....
edit...
If I was ford, I would throw that project over the cliff before they have another disaster
seriously how hard would it be to work with CAT, Deere, or Ivenco to source an engine??

Just wait until you guys see the light duty Cummins. Things get a little more complicated.
i hope your not referring to the 5.9 v8 cummins that was suppose to go into the 1500s? because i beleive that plan got scraped awhile back, would have loved to see it though. -

It is there to close under certain conditions to increase the load on the engine to assist in increasing the exhaust temp for emissions.
Emissions controls are ghey. Diesels are looking like the gas engines of the early 80's with 8 million vacuum lines, haha. You can see the electronic throttle in this pic:

The funny thing is the cummins passes emissions with half the shenanigans as the other two.
lol and it is the only combo that passed the 2007 and 2010 emission standards way back when it was introduced........... I love how the other two had to design an engine to meet 2007, and then go back to the drawing board scratching their head damn hard on how they were going to pass the 2010 standards

They aren't too bad.91nbtsi;287106 wrote:

Main reason was for the emissions but also they were getting so much condensation, ice was forming inside the intakes and the turbos, some chunks being big enough to break fins.

In fact they were so far ahead they didn't have to fully meet 2007 and 2010 standards in class 8 trucks because of all the credits they have. The governements next step is eliminating credits though.

can anyone offer links to substantiate that the usa is tougher on diesels than europe? i remember reading it last year, but i can't seem to find itWith the 2010 emissions they will be ahead of Europe in Nox standards, google it and it should be everywhere. Funny thing is 2004 emissions they wanted to get emissions down by using egr, but that increased exhaust temp too high creating high Nox levels, so 2007 they wanted to lower that with ulsd fuel and dpf, now 2010 they want it lower. Everything they have done adds weight and lowers fuel mileage, they could have just let engine manufacturers meet a mpg rating, thus lower emissions because less fuel is being used, which would save everyone $ except oil tycoons and the government taxing the crap out of fuel. Go figure.

that's my point. the harsher the standards on diesels, the less they will shine and the less people will want to buy them. more diesels on the road means less money for the oil barons and refineries.besides, requiring a mileage goal would involve activists shouting "double standards!" because of the lax requirements on gasoline. bad publicity, no matter how you look at it.
personally, i'm pleased that diesels are about as well accepted as linux.
