Fusing with fire
I have no idea but remember, this is a Ca. Truck. Smog is an issue.

Fusing with fire
I just wanna build something that will last and pull a boat sometimes.

I believe it became obvious when the dowl pin fell out and as a result gets lodged up in the rotating cam, pump gears and causes much damage. Just saying

@Cope what kind of smog checks does CA do for a 2004 diesel? There isn't a whole lot in the way of emissions controls on those besides the injection system and EGR as far as I know, which admittedly isn't much lol. CO basically just did an opacity test but it was pretty lenient, you could turn up the fuel on most pre-2007 diesels and still pass.

it can be tuned for more power and not blow black smoke,..black smoke is un burnt fuel, thats not making more power! idk if it pass smog test but it can burn clean and still put out good power! i ant talking bout pulling truck power, just 50 to 75 more hp and couple hundred more rpms!
The 04 has a Bosch Common rail pump. The p7100 was used only on 12 valves from 94-98.5. They can be swapped on to the later engines but it’s really not worth it unless you just have to have mechanical injection.
You have a Bosch CP3 pump. You would know it if you had a P7100 as it’s mechanical injection and anyone going thru that expensive set up to swap it, isn’t just gonna do it without playing with the fuel and timing of it, IE it ain’t passing CA smog with a P pump conversion.
No such thing as a PT pump or a p700.
Only injection pumps used on B series from 1989 to present are:
The VE pump, 89-93
The P7100 in-line pump 94-98.5 12 valves
The infamous VP44 rotary 98.5-2002
The CP3 common rail 2003-2019; (switched back from the CP4 to the CP3 starting 2021-present)
The CP4 common rail pump, 2019-2020
True but what I meant was the more people started messing with them aftermarket wise, it definitely became more well known
He has a common rail, all he needs is EFI Live that Quadzilla used to sell or a Smarty CR, or a TST PowerMaxCR, or similar, he can gain 100-180 hp and double that in torque and simply remove the thing when he goes in for emissions and they’ll never know. These are all programmers that play with injection timing, pulse and fuel flow rates. The SmartyCR would be best as it’s basically a hand held scanner that takes the factory code out of the ECM, puts in an aftermarket tune. Takes less than 30 seconds, no wiring no evidence etc. then it can be switched back in the same time and no one ever knows.

put a lot of miles on a 6bt but never got to work on one, im much more knowledgeable on big cam 1,2,or 3's!! thay all come with the PT (pressure-time) pumps, all mechanical! wish some body come out with one them programmable deals you speak of for a cummins N14! could sale thousands of them, same for one for the detroit 60 series too!!
Yeah we’ve got an early n14 big cam 1 in our grain truck, all mechanical but the pump on that thing is massive

mechanical N14s are rare and highly salt after, got the steel top pistons and you can make alot more power before melting it down!! pull cap off back of pump see what button in it and drop it to a button 5 numbers smaller, a green and yellow spring and as many rpm shimms as you brave enuff for,..youll have fasted hill pullin'est ol grain truck around!
Here’s the cool part about the old 12 valves… all you need is fuel and a way to turn it over and it’ll start.
This 98 12Valve I got running just by connecting a fuel line to a 5 gallon can, jumped the starter with a jump box and off she took. Removed the jump box and she stays running.

If it were mine I would, dad won’t let me. He’s a purist on everything. Drives me batshit crazy

my dad would turn one up twice as much as anybody else and send it! his last truck had stainless stacks that were blued from how hot he had it, 2100 rpm redline he turn it 2800! g'pa was like your dad,..leave it set where cummins set it! dad get 100,000 on a rebuild, g'pa put a million on his last truck never went lower than valve covers to adjust rockers! put that many miles on the factory clutch too, when thay pulled it the disc were so thin the rivet heads were wore off, kenworth put new clutch in free, said any man put that many miles on one shouldnt havt to pay for it
Not that I disagree (I don’t) but I have a funny story about that.Finally someone who gets it. Rolling coal............Look at me everyone!
When I was sled pulling a bunch, I landed a gig with a sponsor that was for many years, one of the leading aftermarket diesel performance companies. Well back in the winter of 2008, we were on the dyno with my stock truck, testing out one of our new programmers. At full tilt, it would make an otherwise stock truck smoke.
Well part of the requirements to sell this thing was that it had to pass California Air Restrictions Board aka CARB. So how this works is the board, for a fee of course, flies out a test rep to hook all sorts of emissions sensors up.
So we’re testing each level of the programmer, there’s 10 total, with each higher level, it’s increasing boost, fuel and timing. Well about half way through, the tester watching the exhaust video that we had on top of our dyno cell’s exhaust vent. It’s pouring black smoke. But the emissions are still easily within the CARB specs. So he has us shut down, he swaps out all the sensors and we start the test back up. They show the same thing, so we hit level 10, it’s black as black can be rolling out of that vent outside, he goes out side and just watches. Even on level 10, and adding nearly 180 hp and over 300 added ft lbs, the thing passed CARB requirements.
So the tester stunned, doesn’t know what to make of it. So he swears up and down something has to be wrong. So Mark, my boss and company owner, asked the guy if he wanted to put his rental car on the dyno and verify that nothings wrong with his equipment. So we do that. And now I’m stunned as no BS, that 2008 Honda rental car, that yes passed the CARB requirements as well, actually registered higher on the emissions than the truck on level 10 belching more black smoke than a coal mine fire.
Needless to say, the programmer got approved for sale in CA and to this day, still passes everytime it comes up for renewal.

I love my programmer its the race me one, mine only rolls coal when I get on it but after that normal exhaust and for a 3500 dually its kinda scarey how fast this thing goes, and I only use street and performance tune, don't dare run the race tune. I figure on performance I'm over 1000ft lbs of torque since my base is 850 ft lbs on mine.
Some smoke when making big power on a diesel is unavoidable. Especially with big turbos.
It’s the dipshits that installed smoke switches and restricted inlets to generate nothing but smoke that’s the problem.
Though I’ll admit, I did sometimes use the smoke on my daily as an anti tailgate weapon. Worked effectively
My best numbers turned on stock turbo(ish, it was modified but stock housing) 467 hp at 2100 and 1545 ft lbs at 1800 at the rear wheels. I’d hit 50 psi on boost nearly instantly. I sheered the hub out of south bend double disc instantly with the Comp box . That box hits HARD of throttle.
If I’d just stepped up to even a 60 mm turbo , I’d been pushing 700 easy. I had the fuel to support it just not the volume of air

totally off topic, but do you know of a controller you could suggest to get better mileage and more power out of a '17 5.7 hemi ?
(i understand the gains wont be as earthshattering as on a turbo engine)
Not really into that nearly as much but I have heard very good things about the Diablo Sport Tuners.
What kind of mileage are you getting? My wife has an SRT Durango with the hemi and AWD, fully loaded. Thing is a tank but getting 22.8 average driving county roads. We got almost 26 mpg out of it with an average speed of 82 mph going to Florida last may

if we try i can get low 20 out of my wifes AWD charger (R/T version) but it is usually closer to 17
and on road trips i get 15 out of my 2500, probably closer to 12 around town
the 2500 is our family hauler, so that is the one id like to stretch a little

Mines all stock except for full deleted and the tuner with a better air filter. Would be fun to see what my truck puts down I'm only guessing over 1000 ft lbs
