In my studys and knowledge of engines it has always occured to me that cummins stand out from the rest the crowd. The 5.9CR is a very powerful and common engine to see turned up but then there its big brother the 6.7 that sits alone with not many high powered cousins. My question is why are the companys not doing much for the 6.7 when compared to the 5.9? Youve got almost 1 liter more to use. The 6.7 still suses the bosch commonrail system. So why is it everyone is drooling all over the 6.4PSD and d-max. I HATE the 6.4 engine. I just think theres alt left untouched on the 6.7 yet. Any ideas on thr 6.7 neglect.Maybe programming and the turbo is the limiting factor?

When i first bought my 6.7 my friend told me I would have to contact NASA to be able to order stuff for my truck. I didnt get it at the time but now i understand.

drperformace just came out with a billet one piece vlave cover ill probably get that

I think all the emissions may play a role. It is hard to do anything to it without ripping off the emission stuff. I think the magazines and performance people are scared of the smog police.

They should be worried about oil spills and nuclear this and that not smog from our tail pipes pfffft we can do amount of damage to Eco systems and nature in gazillion years what government does in weeks of time

The 5.9 HPCR has been out since '03. In '05, it was still kinda hard to get performance parts for them.

In 2002, it was hard to turn up a 24v.

In 1997m getting a 12v turned up, was competition use ony, and then, 400HP was tops.

Give it some time. That's the way Cummins are.

I just hate to see these v8 engines getting all the attention. The 7.3 never did and it was an awsome engine. I hate the 6.4 its a piece of crap i hate everything about them from the stupid HPFP buried in the back of the engine that you gotta take the cab off to change to the junk front covers they use. The maxxforce7 base 6.4 istn nearly as big a piece of junk. One of our techs workedforford and came to us because he couldnt stand the 6.4 any longer. I want to see some moreparts for our trucks!!!

 

[dMerrell89]

That and theres not much out for the 68rfe's either to hold more power

Yeah get stuff for you guys too with autos!!!

Where is this valve cover you speak of. I wanted an aluminum valve cover to drill and tap to add a fitting for my oil bypass return.

I can't find any pictures or prices for them. I would also like to see an aluminum cover similar to the stock one that is plastic which is normally removed when the EGR is deleted.

I agree the diesels are the new hot rod and I want to see more aftermarket for them.

I want the RSD EGR block off plate just because it is anodized with the skull logo, unless I go to a complete intake tube.

I would also like to see some more stainless braided hose replacements for the factory hoses, or hard lines. I have the mastercool crimper and I think I will have to make some SS lines for myself.

The valve cover isnt on the site yet. Pickup the new edition of Diesel power and its in there. Or you could call them. Bet its lik 300 or 400 I was going to go with his but i went with the shibby cause it was cheap and plan on getting rid the 6.7manifold and intake manifold

I disagree that the 6.7 is being overlooked. There are companies out there that focus pretty much 100% on the 6.7. H+S comes to mind as probably the top programmer at the moment. I'm pretty sure they also have the best transmission programs too. Not to mention all the custom stuff to remove all the emissions equipment. Developing products takes time. Cummins and Dodge have made it very very very hard to break into their computers, so it's taking longer for than the Chevy and Ford.

What everyone needs to keep in mind is that great engines, such as the 7.3 and the 12V are long gone because of the EPA and emissions regulations. Not to mention that the newer engines are putting out double the horsepower as the old engines, while being MUCH cleaner, and getting almost as good fuel economy even though they are much heavier and have much higher capacities as well. Although deletes may be required to obtain the best mpg's, the trucks are still MUCH cleaner and more capable than the old and noisy rattle boxes.

i partially disagree. Some companies have given up. Look at Diablosport, superchips, etc... They've bailed on the 2010 6.7 Cummins. Sure it's hard to break the computers. Maybe there aren't enough trucks out there to justify the man hours / expense. But for right now -- there is SOME "wait and see" going on by the tuning / aftermarket companies.

 

[powerstroke8994]

Cummins is making everyones job harder. I just want these things to get more attention like the 6.4psd

I did say that the programming was much harder to get into on the new Cummins. Companies like Diablosport and Superchips just aren't that good. You wouldn't want to run some junk on your truck would you? I was at an Autozone one time and the girl there called a Superchips a Sunchips, and she was serious. Enough said I think.

I'm not sure your point and I agree with your original statement with the exception that there is more than one reason that there isn't more stuff out for the 2010 6.7's. One is it's difficult and that companies might not be that good.

The other (I'm proposing) is that some companies for some reason have decided to bail and sit on the sidelines and not even try to develop products for the 2010 dodge 6.7's.

 

[powerstroke8994]

I KNOW these 6.7 engine have complex programs built into them. Its all in part to keep guys like H&S out and to help make the truck run correct. H&S just cant go in and click the turnoff regen system button. It takes alot of reconfiguration ect. There are years that go into designing a engine ecm program. There are alot of things that make up and ecm. Time will tell though i guess on this issue

 

[StaffyBull]

The reason for the 6.4 love is it makes cheap big power. A tuner and a pipe and bam and you can crack the mid to low teens. Yes they are a pain in the to work on but they have also been out for 4 years and Ford hasn't made the comp that hard for companies to crack if they even really changed it at all from year to year.

Dodge on the other hand has made it a pain to crack the comp the last couple years. Plus with the change over to the 10 the other little things that need to be reworked. Also there not a ton of the new Rams on the roads.

But the biggest reason would probably have to do with the economy. Companies are not going to dump money into R&D, tooling and production if the sales arnt there.

Well the big thing with Ford is they're more so known for the whole ride in style and haul nothing or a mediocre load. The only one I'd personally own would be a f450. And also the majority of the fueling elements on the dmax are almost the exact same on the curmmins from the cp3s to the common rail. Just to give you an example to the first point I live in far NW Houston and the majority of diesel I see is alot of high blue to low white collar folks that have no idea about there trucks nor plan to mod. Now you go to my east just about 15 mins. and nothing but cummins. I can't go through the center of town without getting someone try and huff up at me. Now for the 6.7 mods for the majority of folks there's plenty of aftermarket parts available. Just keep in mind the 6.7 was designed with tremendous amounts on egt restrictions from the inch wide intercooler, throttle valve, egr, dpf, restrictive grid heater, exhaust manifold, and the stock Turbo which is abouts 60mm but has a very very limited ability to evacuate exhaust gasses. All of these things work together to help in keeping egts sky high which also ends up killing the life of the motor. If I had to recommend an absolute mod would be a 3rd Gen manifold and Turbo considering the engine is starving for air from the factory and the stock 6.7 fueling is almost double that of a stock 5.9.
