Diesel Dynamics Upgrade - What would you choose?

[KatDiesel]

I'm just curious... ... . what would you choose if told you could only have one of the above upgrades?



Leave the cost factor out of it for this poll.



And for the record, no I am not getting anything free.

Went for the Cam... not much more HP but it comes on sooner and it gives you more mileage. It is one mod that could pay for itself if you owned the truck long enough.

I can have all of them, If you only want one thats your deal



seriously- After spending ten minutes thinking about it, Well I cant make up my mind. If you did the cam you could add more fuel with lower egts. But if you did nitrous you could add more fuel add change the turbo to get lower egt. If you ported the head it would breath better so you could change the turbo and add more fuel. If you did the pump you would have a different fueling curve that could give you better bottom end that would spool a turbo up better, Or you could save your hard earned money and do them all and have one bad a$$ running machine.

WHAT!!!

No injectors Or any other of the great mods they do.



My vote is for the camshaft as well. Although I have a long way to go before I get to that point

Injectors, fueling boxes etc are what I consider average typical upgrades, the above listed ones are what I would call "advanced" upgrades... . not everyone will have them I was just curious last night is all. I should have two out of the four by May Madness.

Kat,

My guess is you'll have the Head and cam. If I had to pick only one it would be the cam though.

I voted fuel pump. The stock VP44 durability worries me, the OEM cam doesn't.

 

[Bob Wagner]

HEY!!!!!!!!! Give me that PUMP!!!!!!!

Oh Yeah!!!!! nice 75HP gain

 

[Mopar-muscle]

i can't choose just 1

for me i need 2 on that list .



top fuel , i'm not sure what DD does to the pump makes it live any longer , its a POS by design ...

Mopar, they remove the tacos and burritos that the assemblers left in them.

I don't think they eat tacos and burritos in Germany.



The pump itself is not a POS, it does exactly what it was designed to do actually. They weren't exactly intended to be used in the manner we use them.

You got 1 correct. Leaning more and more towards their cam, the more I think about gaining fuel milage and quicker turbo spool up The head I figure they will ship to me anytime... ... I hope. The injection pump still up in the air... . they ain't available yet. Dragstrips are starting to open... ... ... sooooo thats why I need the other upgrade.



Eventually I will have them all... ..... small minor details of several hundred miles from here to Vegas... . and only 2 weeks vacation

Substitute sauerkraut... .



I was in Mt. Moriah Dodge here in Memphis last wednesday. Two unBOMBed Rams in the service bays, both with defective VP44s. If Cummins ran VP44 style pumps on their class 8 M-11's and N-14's they would be out of business. Period. It's a marginal design. (IMO)

It would be better if they would let people actually work on the pumps... . to discover the problems and why they occur. But Bosch is being pig headed about the info on them.

Kat,



Guess it depens on your master plan for HP. Personally I would go with a cylinder head, but thats me and this is the reasons

1. Decrease in EGT's

2. Ability to add the thicker gasket or if major boost is in the works (o-ring the block and have a receiver groove cut in the head while its off.

3. Possibility to stud the head instead of bolting it. Helps keep her from skating around during high boost or cylinder pressures.



I recall a post from you about Nitrous being added. the changes you can make during the head work with the above mentioned tweaks can help it stay together.





Too bad you could not do the cam and head together while she is all apart one time.

I got a good job... but not that good Yes ideally I would like to do them both. But thats mega bucks. I figure get the cam while I am there and then add the head when i can... since it can be shipped out and not in house install type thing (i think).

 

[Batman]

Went with the ported head for the poll... ..... however, I agree with a previous post, would be nice to do the cam at the same time

 

[rubberneck]

All of them of course

But if i have to pick just one, it would definitely be the modified vp44. With this stupid HO version we have on the six speed, i just cant get enough #2 in her. With all the boxes set to nuclear and the dd3's, i see about 100 degrees less peak temps than my buddies with the ETC motors. Need more fuel more fuel more fuel.

I'm Still a little miffed....

about the the dealership wrecking my dually. I re-read my posts and they have a bit of a vindictive edge to them that I don't like to see. I can do better, and I will.



Where I work at we are running 14 of the 12 valved engines in yard jockeys spotting trailers. They run 24 hours, six days a week. I bought my '99 Ram with faith in Cummins' engineering department that the 24 valve would be an even better design than the incredibly durable 5. 9 B engines I was already familiar with. Well, I don't feel as if the fuel system on my ISB was engineered with the same level of durability and reliability as the mechanical lift pump and P7100 fuel pump on the "old" engines. I paid a LOT of money for something that should have been "new" and "improved" and I'm now left with the feeling it was mostly just new.



KAT, you are 100% correct about Bosch being of no help and little in the way of information. As you already know the fuel system design Cummins uses on their over the road engines is entirely different from that of our ISB Bosch setups. I do very much hope for the new common rail system to be at least as reliable as the old mechanical fuel systems on the 5. 9 B's. Time will tell.



BTW, Yes I am a proud veteran of the lift pump failure-fiasco that so many other brave souls here have soldiered thru.
