Ah, right on then. And the rv275s are drop in? Proper spray pattern?

 

[CATSTACKS]

yes.. on 24v's... they had the 275hp in 97' they de-rated it for the dodge truck application. im not sure if they have a different VP in them... ive never replaced a pump on a motor home but countless ones on dodges...?

 

[flubyux2]

Good point... That's kinda weird the rvs aren't letting go like the trucks are. Maybe the truck vps are built to a different spec, like per mopars request. I do recall reading something that cummins stopped backing up the 5.9 in the trucks after the 12v. I guess the 24v was built to dodge specs while the 24v available in everything else was cummins' spec.

ive heard the exact same thing about the 6.0 powerstroke... the ones in international/navistar products (busses-delivery trucks) had less than half the problems that the fords did.... reprogramming the ecm to ford spec and emissions tuning is what dicked it up...

 

[flubyux2]

Yup, I've heard the same thing about ford/international. The 6.0 in commerical trucks actually worked, like buses. Instead of the powerchoke, the vt363 held up ok. But ford based commerical vehicles still blew up: ambulances, fire rescue, paramedic (e-series, f-series and excursion-based conversions. I've learned a fair amount about how ford screwed up the design by pushing international for a finished product. Coulda been great motor if ford hadn't forced international to compromise.

Maybe rv/commercial ip would work better than the dodge-spec pumps.

Same common factor for longevity, in all Medium Duty applications the RPM limit is much lower, and the VP44 used in these applications follows these guidelines.

 

[CATSTACKS]

that sounds about right... in a dodge with a VP the pump could be starved multiple times per day when it revs to 3500rpm... in a bus with an allison and a 6 something to 1 rockwell the engine rarely turns more than 2k... makes sense...

ah yes, very good point. I didn't even think about that. So its not really secret tuning, just not abused like the trucks.

 

[CATSTACKS]

they have different tuning(50+HP over dodge truck) but i doubt that has anything to do with longevity... it has to do with the engine constantly pushing a 20klb bus vs a 7klb truck lol id love to have the bus drivetrain in a pickup tho... 275hp and a 545 allison behind it stock! BEAST!!!

 

[CATSTACKS]

will any nozzle work in a 12v as long as it has a KDAL59p6 holder and a DSLA145pXXX nozzle? like the 3 or 4 digit number can vary? like: P464--P1174--P263....etc

whats the diff in a KDAL59P6 and a KDAL59P22... it says their both for a cummins 6btaa 5.9...

and this one here KDEL99P39 DLLA152O496 says its for a ... CUMMINS/CDC 6BTA-590??

 

[BOOST]

soo 700hp on stock turbo and injectors......and you "love your cummings". please go outside right now, read the side of your truck, then come back in, and change your sig. hopefully your just joking

+1 I hope he is joking a little exaggerated on the hp you better get a better calculator.

Yes, as long as it is for a Cummins application with a 28° incline angle, you can use varying spray angles 140-155°. With some modifications, you can also use a few 8.3L nozzles in the 5.9L application.

whats the diff in a KDAL59P6 and a KDAL59P22... it says their both for a cummins 6btaa 5.9...

K - nozzle holder
D - external thread on nozzle-retaining nut
A - spring at bottom - nozzle-holder diameter 17mm(P style)
L - long nozzle collar
59 - length in mm
P - nozzle(collar diameter 14.3mm)
Following numbers are serial number

and this one here KDEL99P39 DLLA152O496 says its for a ... CUMMINS/CDC 6BTA-590?

Won't work, 21mm diameter, 99mm length.

You should stop looking at nozzles on Chinahanji Power, but if you are curious the following nozzles would work best, DLLA145 P574 5x0.010", DLLA145 P605 5x0.0095", and DLLA145 P606 5x0.0105".

 

[bjorkmae]

xzq103, I sent you a pm

 

[CATSTACKS]

the following nozzles would work best, DLLA145 P574 5x0.010", DLLA145 P605 5x0.0095", and DLLA145 P606 5x0.0105".

all of those are near stock size??

so as long as the holder is a KDAL59P it will work? the numbers after the P dont matter?
a DLLA and DSLA nozzle will swap in the same holder? whats the diff in them?

 

[xzaq103]

Yes, good luck finding a hone size much larger without compromising the angle.

so as long as the holder is a KDAL59P it will work? the numbers after the P dont matter?

Not necessarily, some nozzle holders have the M12x1.5 connector, some have edge filters, some do not.

a DLLA and DSLA nozzle will swap in the same holder? whats the diff in them?

Yes, nozzle type, VCO vs Sac type.

couldnt i just get some 155 nozzles and get a marine kit when i rebuild my engine this summer?

which ones dont have the filters? their kindof a PITA to get out...

 

[xzaq103]

Yes, or use 1st Gen non intercooled pistons.

which ones dont have the filters? their kindof a PITA to get out...

Typically only some of the 1st Gen nozzle holders, they don't need to come out, I've built 5x0.018" with and without them, saw no difference.

 

[CATSTACKS]

they don't need to come out, I've built 5x0.018" with and without them, saw no difference.

every performance nozzle holder ive seen has them out?

 

[xzaq103]

Then you haven't seen enough.

 

[CATSTACKS]

who doesnt take them out?
