Just wondering if anyone else is pushing their early 2004 Dodge Cummins with performance upgrades? Here's what I did:

90 HP nozzles from Dynomite Diesel

Water/meth injection

BD Twins

4" Stainless exhaust

TST Power MAx CR R49

Smarty

ARP Head studs

Glacier fuel pump (not yet installed)

ATS Billet transmission (input shaft, flex plate, co-pilot, torque converter)

I think I should have got the "Race Track" twins from BD. Yet I haven't turned the boost up on the standard twins just yet. I get about 42 right now. At this boost I believe they are barely working!

I am with mine... have a few more upgrades going in end of month. Not all stuff is in sig. i think you should have gotten the race twins too!! Although I do know one guy that has the tow twins and has pushed 70+ psi with them.

early 04 here its been fun playin around with it, but i think i need to step up to twin turbo set up. running 80 mph i am at 5 lbs of boost and the temps stay around 650-700 but i have a constant haze of black smoke while driving and just hit the cruise button to speed up another 5mph or so and boost jumps straight to 40 and i black out everything behind me. it seriously never cleans up at all

How does the diy cp3 perform? Was it difficult to do the modification? I read someplace where they show you step by step to do it. When they said grind a larger oval in one of the cp3 pieces I became nervous. I'd probably screw it up. I did all the work myself on my truck and I am fairly good with tools, but I don't know if I'd trust myself with my stock cp3. Any performance increase?

Im slowly working on my 03 mods are in sig just waitting for some dyno time to check out different programmers


Nick.

So how do you have a 235 hp cummins. Is that with double new york emissions or something. I thought they were 305/555 in 2003 to 2004.5

I bought my truck used. The marker on the engine reads 235 HP.

Also. . . I'm not bragging that I have the 235HP! I just got it for a steal of a deal.

That should not be so. Im not doubting nor was I accusing you of bragging about it I was just saying the rated hp was 305/555 and in o4.5 it switched to 325/600 and in 06 it changed again. Was the California model detuned that much. Surley not thats alot.

The guys who have a 235hp cummins have a S.O, where as most of us have a 305/555 H.O high output cummins.

To help with the confusion, 03-04 came in three flavors!! 305 HO and either 250 SO or 235 CA emissions SO.

FWIW... Smarty makes them all the same!!

Moobesor:

With the mods you have listed, you are capable of asking for more fuel than your cp3 can deliver. You need more than a DIY mod... suggest at least a Floor IT stage 1 Cp3 and you are better with a stage 2.

Never new it was so low. California rocks. But I guess you guys will live longer that us no emissions testing rebels in the mid states. Atleast according to gore.

Yeah, all that fresh air and sunshine!! But we'll die early from over taxation, over regulation, or just plain shot from the criminals the court system lets go...[yuk]

I'm builing mine for about 500hp and a little change hopefully.

Have Airdog 100, Smarty, CFM+, 4inch out to stacks

Coming soon 62/71-13 ss, SBC con OFE, MP-8

Im not sure if im right but i thought they changed in 05 to 325/610?

04.5 was rated at 325/600 and then in 05 they changed it to 325/610. Big deal. Most people say that they didnt change anything. Just changed the torque claim.

but isnt the 06 the same? 325/610?
