Cummins vs Powerstroke

[Jason]

Name the companies that don't have issues so I can search for issues. It's not Cummins, or Cat or Navistar because I can think of issues off the top of my head for those.

I said rarely, not never. Hino is one. Mercedes is another. And that's just diesels.

well as for the duramax, they dont go out as soon as you think. i guessin all you here are horror stories about them but these motors actually go easily to 300K no problem if well taken care of maintenece wise. The only dmax that had a headgasket or inject problem was the LB7 motor (found in the 01 to early 04 HDs). the injectors would go out as mine did due to too much voltage running through them (92 volts) to work them. the head gaskets were a hit or miss as the gasket its self was too thin to begin with, not due to streching head bolts. all of mine have been replaced under warrenty as most anyone else with that motor and fixed the problems permenatly when used under stock conditions (no high hp chips and such).

When chevy came out with the LLY motor all the injector and headgasket probs were fixed and they only got better from there. The LB7 motor is my fav as i know how to work on dmax's and that motor can run like a raped ape with little mods.

As for no need for a 30k to 40k truck and farmers dont use them, i kinda have to differ. I plenty of people out in the Midwest that use the hell out of their dmax for farming. Now for saying your friends are immature, that may be true but for fellas like me (yes im 22 and not ashamed of it) i built my diesel for off roading and draggin broke vehicles out (including my own), towing my dads 16K double decker tongue trailer when the motorhome cant take it some where and watching the faces on rice burners, cameros or mustanges when i beat them in a race. I dont live at home and hate when people assume "mommy and daddy paid for it", that truck is all my money and am proud of her. Sure i could build a ranger or some gasser truck but for what it cost to build a diesel up, its the same if not cheaper and its more fun to drive IMO.

Now im not tryin to start anything, jsut adding fact to your opinion.

Sorry, I should have added that dmax's that have been 300 HP chipped with a bigger turbo, etc seem to throw in the towel early. I'm sure in stock form they'd last like anything else. But you are correct about how they respond to mods, they are excellent in that regard, which seems to be why everyone mod's them. My point was that they just don't seem quite as stout as a 6BT or 7.3 Navistar in terms of brute strength. But currently, compared to the 6.4 ford or the 6.7 cummins they are the pick of the litter.

As for my friends, yes they paid for their trucks all on their own. I just think it's immature and short sighted to blow your life savings and take out a loan to buy a truck to drive to work/school when you still live with your parents. I just think the money/loan would be better applied to something that stands a chance of appreciating like a home or a college education or something like that. But hey, it's their money. I can't really complain too much because they do let me help them play with their toys!

Although it takes a LOT of mods to make a dmax keep up with my 4-banger ranger

Even living in the middle of corn country, I know of only 2 farmers currently running diesels. 1 runs a 97 F-250 with a 7.3 with over 500,000 miles on it and the other runs a 02 Dodge dually with the 6BT. Like I said before, the ford 300-6 is by far the most common motor in a farm truck around here.

Too bad Cat is getting out of the on highway engine biz. even the ISX was a hell of an engine. I passed alot of trucks uphill with my T660 when I had it.

Great motors untill you have to work on them, Out of the fleet of company trucks the cat powered trucks are in the shop more then the cummings powered.

I don't doubt you, but it looks awful suspicious when you can't even spell the motor's name right. It's Cummins theres no ing about it.

What motors do those have that are 2010 compliant? That's all of the reliability problems these days. This is why CAT threw up their hands. This is why the PowerStroke suddenly turned into a POS. The 6.7 Cummins is 2010 compliant. I believe the DMax is too. Ford doesn't have a motor ready for certain. When the 2007 came out all the manufacturers were slapping surcharges on their motors in the range of $4-10k, probably to pay the penalties and keep selling uncompliant motors. So the customer gets an uncompliant motor, pays the fine for the company making it, and then it's more reliable than the compliant one so the Hino looks good and the Cummins looks bad.

Who is 2010 compliant right now in the HD market?

its all about the cummins,

also i read in an earlier post talking about the 6.4 injector recall . . . . there was no such recall . . . it never happened im guessing your source was on you-tube . . . well the 3 techs, service maneger and service writer who made that video lost their jobs because it wasnt a recall at all and they pissed off ford cause they kept getting a bunch of people coming in wanting the recall taken care of and people sueing ford for not upholding a recall when there was no such recall. the reason those trucks would shoot out flames was not because of the injectors it was retards that dont know how do drive a diesel with DPF. they drive it lightly and that causes the dpf to build then the ecm sees this buildup of PM and starts dumping a bunch of fuel on the exhaust stroke this is called active regeneration. and because the egt's were not hight enought it wouldnt light off the dpf so it would go into another active regen, then it would light off and shoot flames, if the truck were to be run right it would only go into passive regeneration and it would not shoot flames. not to mention for active regen to be affective it has to be high idle or moving, it cant be at idle. regen will only start at a part throttle condition anyways but it takes about 30 seconds to complete depending on how plugged the DOC and DPF is

i agree but i dont agree. I do believe you in the fact that there is no recall on the ford injects and that a build up of fuel will cause the flames.

Now what i dont agree with is that you say that driving the truck "lightly" will cause a builkd up in the DPF and when the regen hits, its not hot enough the first time, then the second time it lights on fire. Well if what you say is true about the half throttle then the regen would never happen when its sittin still, thus no flames at a stop. Secondly after half throttle the EGTs would be high enough to ignite the DPF when the regen starts, and no flames. The only way the DPF can cause the flames you see in YouTube or any ford is from a failed injector constantly dumpin fuel into the cylinder and stying in the DPF so when the regen starts it ignites and shoots flames. Not driving the truck "right" so to speak has nothing to do with it, its how ford set their computer up on the truck and how all the emissions works together. I have yet to see multiple dodges or Chevys do what the fords do and i know many people that drive them "lightly". Maybe im missing something but ive yet to see what you have explained

well all dmaxs came with 300+ hp from factory lol. but i do agree on you with the 7.3, that motor is an all out work horse when kept stock or very minor upgrades. i think it was fords best motor, they just needed a better auto.

I did get my truck for a great deal (18,000 in 06) and then i worked my ass off for all the other goodies plus doin all the work myself. I must be one of the rare breed cause im payin for college also and will be gettin out of my apartment and buyin a house after this May when i graduate .

as for the ranger, yeah you got all these heavy duty trucks hands down in a race lol. ive yet to see a sub 10 second daily driver 7K-8K lbs truck. Ill be happy when i hit 13s!

A quick google search will reveal that most companies already have test trucks for compliance. SCR is the key. Hino built some of the least polluting engines so that is all they need.

Cat threw in the towel because they are unwilling to come up with new solutions. It was a simple matter of what they were and weren't going to do. The fact that Cummins and Detroit were taking market share in the on-highway tractor biz probably didn't help.

I did a quick Google search before I last posted and it didn't reveal anything. My search abilities are bad, I know. I'm not arguing, I was hoping you would be helpful.

No, I mean a +300 HP chip That one actually hit 13s and gave my ranger a real run for the money!

And way to go on paying for college yourself! That's exactly what I did: worked my butt off while going to school full time (mechanical engineering no less) and payed all my expenses myself and mostly avoided school loans. Now the engineering degree is really paying off for me and I'm glad I did what I did. I think everyone should have that experience, it really teaches you the value of hard work and what a dollar is worth.

you have a 12 second ranger 4cyl with a m50d?




dayyyyuuuummmmmmm

 

[Will]

I'm waiting for that video. I have one with the 9 second Civic with the stock bottom end beats the 9 second Cummins.

And it takes me 9 seconds to force my M50D into second gear so it's not a canidate for a race truck.

Nope. It runs mid-high 13s like this duramax. They were very close in the drag race. We tried several times and he won some and I won some. A 4x4 duramax/allison is much easier to launch than a 2wd manual ranger. If I had my launches down the results would have been more consistant. There's a very fine line between leaving with the turbo spooled and rubber burning and bogging the engine and going nowhere fast. And yes, the M5OD is holding up great for me (although it does have a centerforce clutch). I'm thinking of getting one built for a 2.3 with the 4.0 gearset because at 16-17 psi, 1st gear in the 2.3 version goes by rather quickly....

There was a guy running 12's with an M5OD over at www.rangersrevenge.com I think he's got a C4 now though.

Oh i got ya, im blonde so it took me a bit lol. Yeah the chip i have goes up to 425 hp on top of the already 310 hp the truck comes with. I just need a tranny, lift pump and upgraded CPS pump to get all 425 hp. should put me right around 13.4 - 13.7. Gunna have to bust my ass to get that extra 6K need to have those goodies . By the way, i dont do credit cards or loans, never really have and it makes ya just love every hard earned dollar you put in your truck

I totally agree. amkes you really appreciate the little thing you have ya know.
