You wish to talk about something retarded? How about the fact that you commented on a post I made MORE THAN A YEAR AGO. Of course it was sarcastic. Government is already trying to take our guns away, I wouldn't be surprised if they presented greenhouse gasses as another reason to take them away. It was simply, a comment. Relax.
@flamineon7 6.4s are a dual sequiental turbo not a twin or a compound its one little itty bitty turbo spinning another itty bitty turbo it was a shitty design thats why it lasted 2 years and now the new 6.7s have one turbo and not two little honda turbos
realy heavy. its not mosly the weight that stops em its a sled digging into the ground as they go further you can see a weight move on top as it pushes the sled down
@warlordx94 the sled its self is about 30 to 31 tons which is about 40,000lbs. the weight box alone w/o weights in it is around another 3 to 400 lbs more
i dont think there are "alot" of 800+ 6.0 liter truckers. its pretty rare to see a ford make that kind of power...unless its a strictly drag/sled pulling truck
yeah and what's crazy there's guys making 750 horse at the rear wheels with a stock transmission! i plan to own one of these trucks soon. '08-'10 f350 four door fx4 with all the options
they had to do away with the 7.3 due to emissions. 7.3's are polluters. But they still have yet to replace them in my eye. i'll never let my 7.3 go. not the most powerful but you can hold it to the floor all day long and it'll still keep going. Mines got 400,000 and counting.
polluters? give me a break, it's just another excuse for the gov to take away our rights. next thing to hit us, we can't fire guns anymore because they emit greenhouse gasses.
Its not a gov. conspiracy sorry to burst your bubble. Put a sniffer in the tailpipe and see. The EPA wants Zero. So thats what the new clean diesels are supposed to bring. The european diesels are no exception. I know the old ones are polluters as i've put an ITX gas monitor by the tailpipe of a 7.3, and a 5.9, as well as Cat underground trucks and John Deere 5220's Sadly the Cat AD45's were the cleanest running out of all of them i tested. I've not tested any of the new "clean diesels"
@thing503 um are you seeing the amount of smoke coming out of some of the diesels? fucking smoke everywhere. i can see where they're coming from. although pollution from cars is only one of the more minor contributors (the major ones being burning coal for energy etc) but at least they're doing something.
@G0tm1lf but most of the black smoke coming out is just soot which will settle on the ground anyway. Harmless, well maybe not harmless, but not NEARLY as bad as the want us to think. Seriously, global warming and this whole preserving mother earth thing is a joke and just a scheme to take our money. Since this whole global warming "phenomenon" has kicked off the earth has actually gotten cooler.
ya my dads 02 7.3 has bout 240k on it hasnt had any problems he use to have a 90 model 7.3 no turbo had 600k on it when he sold it still ran but rear end was bad and im not a huge fan of these 6.4's they will run but eh.. in my opinion they should bring back the C7 Cat and throw 1 of those in new fords =)!
the 7.3 were the best motors that ford ever had in those trucks. but they were a little heavy witch lowerd the amount you could toe or haul. and to much emmisions. but man they would clatter and bang all the time but they sure are ralible. fires up ever time. alot better than the 6.0. but not as good a cummins. the cummins has alot less moveing parts and slighty more quality
ya ford realized a LONG time ago its not about the numbers but about a truck/car running longer and doing so more efficiently. notice how the 4.6L stang is barely slower than the 6.0L camaro? shit even the 5.4L GT500 is a smaller motor and it blows the 6.0L in the camaro
depends...most if drove normally with general towing duties they will be fine....you start messing with tunes and turbos and the 1st thing thats going to go is your head gaskets....replacing the stock head bolts with arp studs will solve that problem....only other problems i know of is egr valves sticking...you can delete that
That's the biggest misnomer in diesel. The 6L is a great motor, you MUST delete the EGR and do head studs
after those are done, it's a pretty decent truck. Turbo upgrade is a good idea too, but I see a lot of 800+hp 6L trucks, it's a good motor, just a couple really bad weak points.
lol Dodge used to make ford trucks for them! lol just google it! Go figure huh?!?! Dodge and Jeep suspension is what everyone copied because it works so well. lol alos Fords are the best selling trucks because theyre so CHEAP. BUT YOU GET WHAT YOU PAY FOR!!! lol repairs....
the nv5600 is heavier duty than the g56, and even at that, they both are pussy ass trannies with way undersized input shafts compared to the ford and allison units.
and for the second part, what are you, 4? or do you have tourettes? or both?
The announcer is wrong. That truck is not a twin turbo. It is a sequential turbo. A smaller turbo feeding a larger turbo. I finally got to drive one of these now that we have them at work. I used it to pull a 12,000+ lb load and it did great. Too quiet for me though.
bosshog 340 is right they arent twins they are compound turbos which as he explained mean they run off of each other. twins are seperated from each other.
No.... It is not a TWIN. Twin turbos are when you have two turbos that separately feed the intake. This system is called a compound or sequential system where there is one turbo feeding another turbo. This cuts down on the tubo lag and still allows you to have a bigger turbo for the power once they are spun up. After that final turbo then it feeds the intake.
twin turbos aren't a selling point, they're a darn good idea. The idea with sequential twin turbos is the little one spools the big, therefore less turbo lag and more boost!
TWIN = TWO !! "TWIN TURBO" Comes in three types of Configurations and the Name DOES NOT signify the Size but rather the Quantity of turbos. Duh !
1) Sequential Twins
2) Parallel twins
3) Compound Twins
The 6.4 TT is a Compound Twin configuration. IE: Two turbos with Two stages of Air Compression in the turbo system. Sequential Twins transition from small to large turbo with a flapper valve as the engine spools them. The 6.4TT Is Compound twins NOT Sequential or Parallel.
agreed i like ford myself but i h8 all forign ars and trucks and its because of peple like redsi81 that our econmy sucks so if u agree go to Ford Vs All and thumb down this guy hes at the bottom of the first page or top of the second
yeah my grandpa has the 6.4 dual turbo. and its to quite... but i hurd one the other day. strait piped with dual 6in tips and it sounded mean as hell..
You know when your playing cards and you know you have an upperhand advantage seeing as what your dealt is top of the line, and it then makes the game boring because you know you'll win, thats how i feel at traffic lights next to dodges...sorry guys.
Let's talk facts here not ego's. The Cummins is rated as a "medium truck duty" engine and Duramax and Powerstrokes are rated as "light truck duty" engines. Also, all highway rigs utilize inline 6 engines, not V8's like Ford and GM. Why, because there is more torque at lower RPM's and better reliability with 40% fewer parts. Read 'em and weep!
Thats right but Ford and GM actually own their Turbo engines. Ford also uses Cummins as an option for their 650's and up, another option is the CAT motor, which has more power but in my experience as a heavy duty truck tech for Ford the Cummins is far more reliable than the CAT. So your right about the Cummins, but even with it the new 6.4 Ford beats the new Cummins Ram. The Base F-650 comes with a 6.4 though, because it can handle alot of abuse and pull about anything. Cummins is still badass.
Yeah, that's right. But with the Cummins you get maybe slightly less power(stock) but better reliability in the long run. The Cat(I think) 7.3 was the only reliable engine Ford put out, which tells you about the advantage to let the big boys build the engines. Ford's are having major reliability problems with the new engines, they are over-complicated. Nice smooth engine when it runs tho
it has nothing to do with the motor or major problems. Its like most new engines when they are just released, there are glitches with certain systems, especially since the 6.4 is all new generation technology. I really didnt get to work on any 6.4's since we closed down so im not aware of any new problems.
My buddy is a Ford mechanic and he says the new ones are always getting towed in for warranty work, one in particular needed a complete rebuild. Ford is losing millions because of it. The re-gen exhaust is a MAJOR liability. Trucks are getting so hot that they catch fire. I don't see GM or Dodge having issues with their systems. Not bashing Fords, but you're right. They need to work the bugs out
Its fords engine but the actual manufacturer of the powerstroke is Navastar/International...so even though ford owns Powerstroke, most of the engine isnt ford at all. Yeah the Exhaust problem i did get, and its a malfunction with the new gen exhaust recirculating system which sticks therefore you get unburned fumes catching fire out the pipes...I used to fix them with a reprogram, but it was a temporary fix since it made it work but it disabled other of its functions, i dont know the fix yet.
Yeah, it also gives the truck terrible mpg. Up here in Alberta where the oilsands are, the trucks are going up in flames all the time. Dirt and oilsand gets underneath the truck and traps the heat. What's the use of the clean burning exhaust too if the truck is so hard on fuel? Kinda redundant. We'll see what the've changed on the '09
thats what we all thought when they came out with that system, WHY? The U.S. emission restrictions is why, so in order to comply not only to that but to California's ( where i live) restrictions they came up with it. They could have done without the new technology showing off right now cause the 6.0 was doing good in emissions. They will work the kinks out.I hope they do..lol.
That's not fucking true, the more torque thing maybe, but Powerstroke has more horse power and will out last any truck, also on fords F-650,F-750etc you have the option of a Powerstroke or a Cummins, you may even have the choice of a CAT engine which has far more power.
the only powerstrokes that have ever been known for being unreliable were the 03 and early 04 6.0. if you want to talk unreliability that has lasted 20 years though, look straight at a dodge auto tranny
I agree with you about the 4 speed auto tranny, that's why I have a six speed manual with a Centreforce clutch. The next upgrade will be my steering linkage to '08 specs, get rid of those wimpy tie rods. I don't hate Fords, I just think that they are overcomplicated with too many parts that can break('08). In my opinion, the perfect truck would have a Ford frame, GM suspension and Cummins engine!I am more loyal to Cummins than Dodge, the only medium duty engine in a light duty truck!!
I love my 6 speed manny with a Southbend. BUT I think the best truck would be a straight up Superduty body and frame with a Cummins p-pumped 5.9 and a Dodge 6 manny. That would be baddass!
actually he was talking about manual transmissions and the 6 speed nv5600 in dodge's is about bullet proof. the dodge autos are bad though. allison is good if you're stock but any slight increase in hp will have it slipping. ford trans are pretty solid. especially the 5r110 torqueshift
Yes it does. Twin turbos are not sequential. The new Ford setup is 8 in to 1 exhaust, then through both turbos. One turbo is larger than the other, making them NOT "twin".
I'm Not saying that twin turbo's aren't without their gains,... You want 25-35-40psi you can have every inch of it....With 1 turbo Impeller upgrades ,turbine housings, ball bearing turbos..50psi with 1 or 2..its less of a headache with 1.
ford didn't do this for huge boost numbers, it simply reduces turbo lag hugely when towing. a smaller turbo feeders a larger one, much more efficient.
Dieselpower25.! Your definately correct, A D= moves enough air+fuel+exh. 2 turbos Make the 6.4 slightly more efficent. Twin turbo D= one smaller turbo impeller=housing spools the larger Turbo.Fuel economy rises... Based on Efficent airflow... One turbo tuned properly could do the same
I think twin turbos aren't needed for anything- its always replacing one big turbo ,for 2 half the size.I think ford went to twin turbo for bragging rights, or.. they must have tuned one small turbo to spin the larger one which is just for acceleration response time. I know a lot about turbos One large turbo works better or the same as 2
I... Agree with you 100%, Turbo lag from one. However, One huge turbo has as much MODified boost easily as 2, 20-45-75psi.The plumbing for 2 is so difficult exh-inlet's.
Turbo technology came so far in the last
15yrs diesels came with it, Ford Loves to say 'WE HAVE A TWIN TURBO 6.4'. One turbo is cheaper than 2 oiling/plumbing/airflow/maintence-
it's not a twin turbo setup. twins are when there's two identical turbos, one off each exhaust bank. this is a sequential setup. and the mod. class pulling trucks run sequential or even scheid used a triple turbo setup to make up to 120 psi so don't think a single can make the most modified boost.
i own one of these trucks bud. they are definitely not twins because high pressure turbo is much larger than the small turbo. you just made yourself sound like a real idiot. sequential and compound are the same thing. "twin turbos" describes a setup where there are two identical turbos, one feeding off each exhaust bank. this setup is an 8 into 1, so definitely not twins. you should feel stupid now.
there are a alot of people that don't know what the hell there talkin about on this site. Chevy making there own diesels? Thats a new one, better lokk that one up again cause your wrong, and none of those trucks have aluminum heads
GM is going to make their own diesel engines for 2010 half-ton trucks and Hummers -- 4.5L Duramax Diesel Engines. 100% made by GM. Isuzu is left out on this one, thankfully.
Google search -- 4.5L Duramax.
2001-2008 Duramax Diesels have aluminum heads -- look up the specs. The new 2007-2008 Vortec gas jobs have aluminum heads now as well. Pre-2007 Vortec gas jobs had cast iron block and heads.
Your an idiot since the LS1 can out it 98 it had Aluminum heads! The Vortec 5.3 and 6.0 always had aluminum heads! Do your homework before you open your uneducated mouth!
I don't talk about the Vortec 5.3L V8 -- they're garbage.
I'm surprised about the 6.0L Vortec's. I thought they always had cast iron block/heads. It did in the year 2000 but, after that, GM changed to aluminum heads.
How stupid can you be? The new 6.4L ('08+) NaviStar/International Powerstroke uses sequential (aka twin) turbos. The first is actually a small VGT (like the one in the 6.0) that spools the larger turbo.
I love this engine, but the new 6.7 Cummins has it beat hands down - matching peak HP and Torque, however peak torque comes at 1400rpm for the Cummins versus 2000 for the powerstroke. The Cummins also has 40% fewer moving parts, 1 less turbo, and 2 less cylinders!
well napiertrucks is partially right. they aren't twin turbos because a true twin turbo setup has two identical turbos, one on each exhaust bank. sequential is not aka twin. there you are wrong. because the two turbos are not of equal size, therefore not twins
Hey, dumb ass! The new F-450 halls 21,000 lbs. Thants 5,000 more the those piece of shit Dodge's and Chevy's you call "TRUCKS." So before you go telling everyone to "look it up," why dont you do some research first???
Chevy is now making their own diesels, not Izuzu like they used to. The last time Chevy decided to make their own diesels, their sales droppped horribly. Durmaxes are not the best, Cummins comes out of the factory with more power. Powerstrokes used to be good until they changed some stuff and made their diesels suck. The twin turbo he talks about is a small on to get the larger turbo upto speed. It really doesn't add anymore power to the engine, it just reduce turbo lag.
dmaxes get slightly better acceleration times, BUT they cant haul anything even close, and their shitty aluminum heads have fucking insane amounts of probs, (cracking & warping at around 40k so far ive heard from 4 people they had em crack right around 40) cummins are pretty reliable motors, but they cant haul shit, and being in a dodge chassis with a dodge tranny makes it basically useless.
Hmmm thats funny, it don't even look like it struggled. I have 3 of the 6.4L and I haven't had to take it out of overdrive yet, doesn't even hesitate.
you need to hook that truck up with a dodge or chevy and pull the hell out of them but make sure to get it on tape so we can talk shit to all them fagets

It's a Bi-turbo. Basically a small turbo is spinning at less rpm producing boost for the larger turbo so that there is no turbo lag.

You know when your playing cards and you know you have an upperhand advantage seeing as what your dealt is top of the line, and it then makes the game boring because you know you'll win, thats how i feel at traffic lights next to dodges...sorry guys.

Let's talk facts here not ego's. The Cummins is rated as a "medium truck duty" engine and Duramax and Powerstrokes are rated as "light truck duty" engines. Also, all highway rigs utilize inline 6 engines, not V8's like Ford and GM. Why, because there is more torque at lower RPM's and better reliability with 40% fewer parts. Read 'em and weep!
JOHNNYGIX 3 years ago
Thats right but Ford and GM actually own their Turbo engines. Ford also uses Cummins as an option for their 650's and up, another option is the CAT motor, which has more power but in my experience as a heavy duty truck tech for Ford the Cummins is far more reliable than the CAT. So your right about the Cummins, but even with it the new 6.4 Ford beats the new Cummins Ram. The Base F-650 comes with a 6.4 though, because it can handle alot of abuse and pull about anything. Cummins is still badass.
Mach1isaac 3 years ago
Yeah, that's right. But with the Cummins you get maybe slightly less power(stock) but better reliability in the long run. The Cat(I think) 7.3 was the only reliable engine Ford put out, which tells you about the advantage to let the big boys build the engines. Ford's are having major reliability problems with the new engines, they are over-complicated. Nice smooth engine when it runs tho
JOHNNYGIX 3 years ago
it has nothing to do with the motor or major problems. Its like most new engines when they are just released, there are glitches with certain systems, especially since the 6.4 is all new generation technology. I really didnt get to work on any 6.4's since we closed down so im not aware of any new problems.
Mach1isaac 3 years ago
My buddy is a Ford mechanic and he says the new ones are always getting towed in for warranty work, one in particular needed a complete rebuild. Ford is losing millions because of it. The re-gen exhaust is a MAJOR liability. Trucks are getting so hot that they catch fire. I don't see GM or Dodge having issues with their systems. Not bashing Fords, but you're right. They need to work the bugs out
JOHNNYGIX 3 years ago
Its fords engine but the actual manufacturer of the powerstroke is Navastar/International...so even though ford owns Powerstroke, most of the engine isnt ford at all. Yeah the Exhaust problem i did get, and its a malfunction with the new gen exhaust recirculating system which sticks therefore you get unburned fumes catching fire out the pipes...I used to fix them with a reprogram, but it was a temporary fix since it made it work but it disabled other of its functions, i dont know the fix yet.
Mach1isaac 3 years ago
Yeah, it also gives the truck terrible mpg. Up here in Alberta where the oilsands are, the trucks are going up in flames all the time. Dirt and oilsand gets underneath the truck and traps the heat. What's the use of the clean burning exhaust too if the truck is so hard on fuel? Kinda redundant. We'll see what the've changed on the '09
JOHNNYGIX 3 years ago
thats what we all thought when they came out with that system, WHY? The U.S. emission restrictions is why, so in order to comply not only to that but to California's ( where i live) restrictions they came up with it. They could have done without the new technology showing off right now cause the 6.0 was doing good in emissions. They will work the kinks out.I hope they do..lol.
Mach1isaac 3 years ago
the 7.3 was not built by Cat it was built by Navistar, a division of International
alnissen09 2 years ago
That's not fucking true, the more torque thing maybe, but Powerstroke has more horse power and will out last any truck, also on fords F-650,F-750etc you have the option of a Powerstroke or a Cummins, you may even have the choice of a CAT engine which has far more power.

Sure on the medium duty Ford's you get a real engine but on the light duty trucks you get a POS V8 that is terrible for reliability
JOHNNYGIX 3 years ago
the only powerstrokes that have ever been known for being unreliable were the 03 and early 04 6.0. if you want to talk unreliability that has lasted 20 years though, look straight at a dodge auto tranny
OregonLumberjack 3 years ago 6
I agree with you about the 4 speed auto tranny, that's why I have a six speed manual with a Centreforce clutch. The next upgrade will be my steering linkage to '08 specs, get rid of those wimpy tie rods. I don't hate Fords, I just think that they are overcomplicated with too many parts that can break('08). In my opinion, the perfect truck would have a Ford frame, GM suspension and Cummins engine!I am more loyal to Cummins than Dodge, the only medium duty engine in a light duty truck!!
JOHNNYGIX 3 years ago
I love my 6 speed manny with a Southbend. BUT I think the best truck would be a straight up Superduty body and frame with a Cummins p-pumped 5.9 and a Dodge 6 manny. That would be baddass!

uh, youre WAY OFF on that trans, chief! dodge has the WORST trannies of the big 3.

KartMan250 2 years ago
actually he was talking about manual transmissions and the 6 speed nv5600 in dodge's is about bullet proof. the dodge autos are bad though. allison is good if you're stock but any slight increase in hp will have it slipping. ford trans are pretty solid. especially the 5r110 torqueshift

Not "twin-turbo". They are dual-sequential turbocharged.

dual means "two".
rodarana530 4 years ago
Yes it does. Twin turbos are not sequential. The new Ford setup is 8 in to 1 exhaust, then through both turbos. One turbo is larger than the other, making them NOT "twin".
mpwelk 4 years ago
Yes, it makes them a "compound" set up. many high performance diesels have that set up.
badazzdiesel 4 years ago
I'm Not saying that twin turbo's aren't without their gains,... You want 25-35-40psi you can have every inch of it....With 1 turbo Impeller upgrades ,turbine housings, ball bearing turbos..50psi with 1 or 2..its less of a headache with 1.
meatman310 4 years ago
ford didn't do this for huge boost numbers, it simply reduces turbo lag hugely when towing. a smaller turbo feeders a larger one, much more efficient.
alnissen09 2 years ago
Dieselpower25.! Your definately correct, A D= moves enough air+fuel+exh. 2 turbos Make the 6.4 slightly more efficent. Twin turbo D= one smaller turbo impeller=housing spools the larger Turbo.Fuel economy rises... Based on Efficent airflow... One turbo tuned properly could do the same
meatman310 4 years ago
I think twin turbos aren't needed for anything- its always replacing one big turbo ,for 2 half the size.I think ford went to twin turbo for bragging rights, or.. they must have tuned one small turbo to spin the larger one which is just for acceleration response time. I know a lot about turbos One large turbo works better or the same as 2
and much less maintence plumbing oiling etc-
meatman310 4 years ago
International went to compound turbos to clean up the emissions on the 6.4, nothing to do with bragging rights, just to keep the damn EPA happy

Louie2994 4 years ago
One turbo makes more sense. But the lag of one huge turbo sucks like if you were gonan drive it on the street everyday or pull 15-20k.
44skillet 4 years ago
I... Agree with you 100%, Turbo lag from one. However, One huge turbo has as much MODified boost easily as 2, 20-45-75psi.The plumbing for 2 is so difficult exh-inlet's.
Turbo technology came so far in the last
15yrs diesels came with it, Ford Loves to say 'WE HAVE A TWIN TURBO 6.4'. One turbo is cheaper than 2 oiling/plumbing/airflow/maintence-
meatman310 4 years ago
Good point
44skillet 4 years ago
it's not a twin turbo setup. twins are when there's two identical turbos, one off each exhaust bank. this is a sequential setup. and the mod. class pulling trucks run sequential or even scheid used a triple turbo setup to make up to 120 psi so don't think a single can make the most modified boost.
alnissen09 2 years ago
You should get your info right!! YES, they ARE T W I N TURBO.
NO, they are NOT sequential. YES, they are COMPOUND twins !!! DUH !!
KB3MMX 2 years ago
i own one of these trucks bud. they are definitely not twins because high pressure turbo is much larger than the small turbo. you just made yourself sound like a real idiot. sequential and compound are the same thing. "twin turbos" describes a setup where there are two identical turbos, one feeding off each exhaust bank. this setup is an 8 into 1, so definitely not twins. you should feel stupid now.
alnissen09 2 years ago
there are a alot of people that don't know what the hell there talkin about on this site. Chevy making there own diesels? Thats a new one, better lokk that one up again cause your wrong, and none of those trucks have aluminum heads
BKDespain 4 years ago
GM is going to make their own diesel engines for 2010 half-ton trucks and Hummers -- 4.5L Duramax Diesel Engines. 100% made by GM. Isuzu is left out on this one, thankfully.
Google search -- 4.5L Duramax.
2001-2008 Duramax Diesels have aluminum heads -- look up the specs. The new 2007-2008 Vortec gas jobs have aluminum heads now as well. Pre-2007 Vortec gas jobs had cast iron block and heads.

Your an idiot since the LS1 can out it 98 it had Aluminum heads! The Vortec 5.3 and 6.0 always had aluminum heads! Do your homework before you open your uneducated mouth!

You are right. I never knew that about the LS1.
I don't talk about the Vortec 5.3L V8 -- they're garbage.
I'm surprised about the 6.0L Vortec's. I thought they always had cast iron block/heads. It did in the year 2000 but, after that, GM changed to aluminum heads.

THEY ARENT TWIN TURBOS
napiertrucks 4 years ago
How stupid can you be? The new 6.4L ('08+) NaviStar/International Powerstroke uses sequential (aka twin) turbos. The first is actually a small VGT (like the one in the 6.0) that spools the larger turbo.
I love this engine, but the new 6.7 Cummins has it beat hands down - matching peak HP and Torque, however peak torque comes at 1400rpm for the Cummins versus 2000 for the powerstroke. The Cummins also has 40% fewer moving parts, 1 less turbo, and 2 less cylinders!
EstorilEm 4 years ago
well napiertrucks is partially right. they aren't twin turbos because a true twin turbo setup has two identical turbos, one on each exhaust bank. sequential is not aka twin. there you are wrong. because the two turbos are not of equal size, therefore not twins

Hey, dumb ass! The new F-450 halls 21,000 lbs. Thants 5,000 more the those piece of shit Dodge's and Chevy's you call "TRUCKS." So before you go telling everyone to "look it up," why dont you do some research first???

justin88990 1 year ago
Chevy is now making their own diesels, not Izuzu like they used to. The last time Chevy decided to make their own diesels, their sales droppped horribly. Durmaxes are not the best, Cummins comes out of the factory with more power. Powerstrokes used to be good until they changed some stuff and made their diesels suck. The twin turbo he talks about is a small on to get the larger turbo upto speed. It really doesn't add anymore power to the engine, it just reduce turbo lag.
LclTechie 4 years ago
dmaxes get slightly better acceleration times, BUT they cant haul anything even close, and their shitty aluminum heads have fucking insane amounts of probs, (cracking & warping at around 40k so far ive heard from 4 people they had em crack right around 40) cummins are pretty reliable motors, but they cant haul shit, and being in a dodge chassis with a dodge tranny makes it basically useless.
