6.7 Powerstroke Vs 6.7 Cummins
 

What do you guys think?

Vs each other for what exactly?

Performance

I'd say they're pretty close in performance. either or is going to have a lot of balls. What i don't like is, i've read a lot of horror stories going on with ford. I've also had first hand experience with a brand new ford lifting the head and blowing all the coolant out the tail pipe.

I have a good friend who works for ford who says the new lift pumps are blowing up and sending all the shards down the line into the engine thus blowing it up. And the worst part is ford is not covering it under their warranty. He also told me to stay the hell away from buying a new one.

I love ford, but that leaves a bad taste in my mouth. Next truck i buy will be a dodge cummins.

For all out performance, I will say the 6.7 cummins is going to be ahead right now. It's been out longer, and a lot of parts from the 5.9's work, so in that regard they have the upperhand no doubt.

If you were actually on some of the Ford forums, you'd see there are VERY few complaints about the 6.7 powerstroke. However I read a LOT about problems with the 6.7 cummins.

There are also several compound turbo kits available now for the 6.7 powerstroke. Is it tight under the hood? Of course it is, there's a lot going on under there. Doesn't mean it's impossible to do anything, just requires more thinking.

500hp has been done already with just a tuner... They just run out of air after that, thus the compound kits out there. Industrial Injection has a kit, and SPE will have a VERY nice kit out soon, if not out already. Keep an eye out for those guys. 6.4's are making more like 600 on a tune FYI.

I suggest you do some of your own research on each respected motors forums. Talk to the Dodge guys about the Dodge (excuse me, the ram), and the Ford guys about the powerstroke.

You clearly haven't been reading up on 6.7 cummins either if you think the powerstrokes are troublesome.

Where are all these horror stories you're reading? I've read about a few turbo issues on the cab and chassis trucks, but those turbo's aren't even the same one's that come on the 250/350 trucks. There were less than a handful of major engine failures on the boards from what I saw, and Ford replaced entire engines. Seems that issue has gone away. Most guys are recording near 20mpg stock with these things too. Go read about the cummins a little bit, I'd never buy a 6.7. 5.9 commonrail would be my choice.

Trust me, i bleed ford blue. My whole family does. My father still owns his grandfathers 1949 F1 ford pickup which he bought brand new off the lot. And my father will leave it to me. I love ford, But all the men in our pretty big family have been pissed ever since the 6.0. The 6.4 lasted a whole 3 years. And the family members who have bought the new 6.7 are not happy either.

I know cummins has emissions problems, as the big three all do. But as soon as you take care of that, it's all cummins from there.

There's a reason why ford doesn't use it's own engine in it's F650/F750. It's junk. Plain and simple. Ford uses the same 6.7 cummins you can buy in a 3/4 or 1 ton Ram.

There's a lot more different than just that.

There's no doubt most of the troubles from these motors come from the emissions equipment. However I'd be tempted to leave the urea injection on the powerstroke, since it aid's in mileage. However let's not forget that not everyone lives in a state where they can easily remove all of the emissions equipment and still have a road legal vehicle. Do we know where the OP is from? A 5.9 might be a far better option than a 6.7 if that's the case.

How are two engines the same if one has a larger bore and stroke?:w2: The heads are different are they not? Seems a lot of guys are putting 12V heads on their 6.7's too.

:c:

I have a 2011 powerstroke and a 2012 Cummins.

I blew the head gausket on my 2010 cummins at 30K never sled pulled with it, I did tow heavy but none of the previous 5.9's never had any problems when I traded them off at a 100K

The 6.7 cummins still has a lot of emission problems especially for the city/occasional tower. And for us heavy haulers the head gauskets are giving out at 30 to 50K Delete kit will take care of all the problems except for the head gausket.

I am putting on a external wastegate on my cummins right now. And I am going to put studs on right away

So far the powerstroke with 8000 miles has done nothing but impress me. Dam good on fuel and it pulls great. If I had to choose 1 truck and I had to leave it stock, it would be the ford

That's interesting... thanks for sharing. I know the 6.4 guys are using wastegates quite a bit, but that's usually only with real hot tunes and full egr cooler deletes, since the coolers are essentially the gates stock.

the 6.7 cummins sure sounds like a 6.0 powerstroke:w2:

The Cummins is a far better engine than the Ford one will ever be. The 6.7 Ford is nothing more than a quick and dirty copy of GM's 4.5L Duramax.

I do love the design of Ford's new v8 Diesel. I have to wait couple of more years before commiting to it.

About the 6.7, I got over 80K on my RAM 3500 so far with no issues, of course FYI, I have got ride of all emmission crap, and I am using a Smarty 67ME. I get on average about 18MPG. The power is very impressive. And the new transmission is just solid. I do love the exhaust brake with toe option.

Thanks guys for the info, a few guys around town here have been trading their 6.7 CDTs in for 5.9s or 2011 PSDs. A buddy of mine has a 6.7 cummins and i would say its pretty nice but he has had alot of emissions issues with it and the guys a dodge dealer straght up said you cannot let those trucks warm up in the cold becuase it will plug those dpf filters. I kinda think thats stupid how you cant let it warm up in the morning but idk if its needed on the newer diesels, im used to the old powerstrokes and we always let them run for 10 minutes when its cold before we drive them. Iv drivin both 2011 PSD and CTD and the ford seems to be a little more jumpy off the line and the cummins seems like it has turbo lag at low end and the new duramax is a whole other story, i was not impressed at all with it, it was a nice truck though.

ill stick with my 2011 6.7L powerstroke i love it no problems yet:c:

118k on my 08 cummins

I had a 08 6.7 cummins and loved it h&s made it come alive but I sold it and bought a 2012 king ranch and I haven't had a problem yet seems to have good power for a stock truck and by far the nicest interior in any truck I've seen. Drove a buddies 2011 LML which is tuned and a delete pipe nice truck but not the least bit impressed even tuned

hahaha Im feeling some kind of mind connection here, ARP is making a killing in the last 10 years :argh::scare2::jump:

But realistically, the new ford is farther than the cummins at this point. Even though a lot of people dont like having to refill the urea, the truck gets a solid 18-20 highway with emissions stuff in tact. Turbo problems are the most Ive seen on the new ford but they are on top of it and are replacing the turbos with new ones

The same way they handled the 6.0's "problem".

Really, the problem for the 6.7 is that the turbo is extremely tiny for 400hp. Its got two compressor wheels, but the turbine they use isn't big enough to drive just one of them efficiently. Thats why they had to add a wastegate even though its a VNT design.

Um no, the fact that they actually fixed the problem with the new redesigned turbos means they are at least fixing the problem unlike how no one knew how to fix the 6.0s the first time around when they first came out. Most of the new trucks dont even have the turbo problem and its more of an annoyance than say your HG's blowing or turbo self destructing.

I read those stories to and seen where diesel mechanics were havin those porblems, I'd say get a 7.3 idi or Powerstroke. :tu:

I have owned a 2008 6.7 cummins and I do own a 2011 powerstroke, they are both outstanding in my opinion. You can read about the dodge in my sig, and the ford has an h&s tuner with a dpf delete. the dodge made about 19~23 mpg and the ford makes 13~15 mpg. I did have quite a bit more done to my dodge, yet I beleive with just a tuner the ford has a chance to outrun it. (they both made about 10 mpg with the same trailer attached) P.S. Damn that ford is comfortable to ride in.

Watch Top Gear U.S., cummins shouldn't even be in the question.
:moon:

Yeah Top gear is 3 Idiot's that don't know there Butt from a depression in the ground about truck's trying to get there thought's about the big 3 Top gear is a Joke :tu::tu:

my 6.7 f350 kingranch has had no problems and pulls awesome with its 800 ft lbs of torque. the tranny is awesome. i was getting 24 miles to the gallon the other day driving on the interstate and i havent done one thing to the truck its all stock. i wish i could run a 4 inch pipe all the way through and put some tuners on it and see what i could get but i gotta wait a few years to do that

From the sounds of it, the mileage deleted is close to the mileage stock anyways... they get pretty good mileage stock (6.7 powerstrokes).

Maybe you should check out the Valanx



July 2012 Military Power: The Valanx - Diesel Power Magazine

Wow. First the 6.5 now a ford V8 for military use. Just put Cummins engines in all Military trucks and never think about them again.

I know you didn't just campare a 6.5 to the new powerstroke... that's a low blow even coming from a cummins guy....

Look I'm just saying you can get from point A to point B by cartwheeling or walking. You can power a diesel engine with tons of complications and just enough engineering (powerstroke) or you can overbuilt something and use as few parts as possible to do the same thing or more. Not saying the powerstroke is a 6.5...not at all...just saying that you can get yourself all sweating trying to do something with complications or you can cruise through with ease. You pick. I chose a mechanical cummins that just doesn't break to gently cruise through the finish line.

haha this is great stuff i am trying to pick witch truck ill go with ill be buying in a couple years so when i buy the aftermarket stuff will be running ramped and we will see witch truck is the best.(after all the bs emissions is gone and it just comes down to the truck) i think its funny though its clear to me that both of these truck have there little problems but are both great truck. but the cheverlet ya down does not rank at all with these great trucks!

i think 95% of people find their answers on google and just go with other (mostly biased) opinions that they read

ford will win

Way to bring back a thread from 4 months ago.....

Ford will win First to the back of Tow truck :tu::tu::tu::tu::tu::moon:

I've heard the 6.7 Ford in stock form is great but I wouldn't want to pay for a cab off egr or head gasket failure.

i preffer dodge but i hear the 2012 6.7 by ford is doing alright

I haven't heard many complaints about the 6.7 Powerstroke in my area, and I haven't heard many about the 6.7 Cummins either. The only first hand experience I have with either of them is my dads excavating company owning 4 Dodge 2500s with the 6.7 Cummins. A 2009, 2010, 2011, and a 2012. We haven't had a single problem with any of them. 2 of them pull a Caterpillar 279C skid loader daily (about 10,000lbs plus a Towmaster T14 trailer and a 100 gallon fuel tank in the bed). Seriously the only things they've been in the shop for is servicing.
