Cummins 4" Straight Pipe

[@korygant83]

My boost is at 29 also and all I've done is turn up the pump, star wheel is turned down, and smoke screw is down too. Also have the exhaust cut a the cab with a 6' long 6" stack under the bed. It only smokes if I stomp on it or I'm towing

[@korygant83]

Oh ya, truck is a 92 W350 dually with 145k original miles. Unfortunately its an automatic, but some day she's gonna get a NV5600

[@Clunk49]

Did you turn in the fuel screw? The diaphram to the fuel pin had a dimple that was at 2:00 and I rotated it to the 6:00 position. I picked up some more boost on my '92 by connecting a 4" exhaust from the downpipe to the back. The stock tailpipe had a sharp turn that was actually a kink in the pipe.

Thanks man, and no, North Lake Tahoe CA

It could be, there's pines in PA up north, but still I realized now how DirtyDiesels is worldwide, so this guy could be anywhere in the US or even in Canada.

I was just given a 1989 W350 SRW by a guy up the road. It is super clean, and runs great, but he pulled the tranny at 200,000 miles when he lost reverse. He had it rebuilt but never put it back in the truck. I am currently gathering parts for the installation and need a torque converter. Are you running the stock converter, and if so, how many RPMs are you turning at 60 MPH? Any help would be appreciated, and that is a SWEET truck you have

[@calven727]

awesome truck

[@FinsleysCustomCarAudio]

Thing sounds beautiful...

[@noahmalcolm921]

Where did you get you gauge mounts. I have a 92 d250 but can't find the mounts anywhere

[@sgfreak96]

I see this truck on dirtydiesels all the time. Its my favorite first gen! Do you live in PA?

[@matthewgavin1977]

I have an '89 first gen Dodge Cummins with original drivetrain in rancher condition. Any idea what it's worth?

[@AcrMast3r]

How are you getting so much boost? In my 91 I have the pump turned up and a Denny stage 2 fuel pin.. and I can only get a little over 15 at WOT

[@thefarmboy31]

how does your hc1 whistle that much, my 91 wont whistle at all

[@Upnorthadventures95]

Turbo silencer ring ? Is yours the intercooled ? Turbo sings a little more with intercooler

[@tanklover10]

Is there anything else done to it besides the straight pipe? I assume some pump work. Sounds sweet

[@MrStryperfan]

is it just straight piped?? and if not what other mods sweet truck

[@coreymcdowell3471]

[@dieselman8v923]

hirocaster Yes, it is a 6bt or more commonly known as a 12 valve.

[@hirocaster]

***** Thanks, this is the engine I want!

[@Morgan-dh1vn]

Do you still have this truck?

[@sgfreak96]

Makes sense, hence the "norcal" in your name. Anyway I have seen this truck alot, and it's probably the nicest first gen out there. I love the pic with the american flags on it!

[@Freedom-250]

My first gen has 45 psi

[@welch12mar000]

sounds just like mine!! but it's faster than mine xD haha

[@kylefinnerty159]

glad your flying the american flag and not the confederate flag

[@inkdup420]

[@magnumbeast6515]

Damn, wish I could find a first gen Cummins up here in New England in that good of shape...but that's just wishful thinking

[@baileymiller546]

My 4" Straight piped Cummins sounds better than yours 😉😂

[@matthewdittmer1837]
