Other Aplications with the VP44?

[TxDieselKid]

Does anybody know of any other place where our wonderful VP44 is used?



I am wondering because ours has a computer controled limit placed on it, and if some other aplication has a VP44, then we could swap them out?, and maybe get more fuel with our boxes???



Just thinking to hard I guess.

Kid,



I don't profess to be one of the leading minds in this forum, but I think you answered your own question in your question. The VP44 is computer controlled, hence the magic 'black box' to override the limit. The VP44 is capable of putting out the fuel, upto a certain physical limit, but the box (or computer) that you're running will determine the fuel delivery.



I'm sure the gurues will correct me if I'm wrong.

Here a while back someone posted the the VP-44 was going into some John Deere tractors useing the Cummins. Dont remember any more.

I would imagine the other current ISB applications (Freightliner FL-60's & FL-70's, motorhomes, etc. ) use the Cummins ECM on the VP-44, right?

I don't think you will find any Cummins in John Deere products! You will, however, find them in lots of Case/IH tractors, combines, etc. I haven't spotted any of the Case/IH tractors with 24 valve engines, but I haven't looked that the new machinery lately. I know the 12 valve engine does a wonderful job! Ray

Ray is correct. As of a few months ago the Case (CNH) Magnum tractors were still using the 12V engine. It is really cool to go in the plant where they are built and see a room with 300 or more brand new 12V engines on the skids. Also keep in mind that the engines used in the Case tractors are not built by Cummins, they are built by CDC which is a joint venture between Cummins and CNH. I would think that the ISB in motorhomes and the medium trucks use the VP44 though, and more than likely it is the same unit we have mechanically. The electronic controls would limit the fueling possible. Everything I have heard indicated that the fueling possible is limited by the CPU in the VP44 itself, to me the VP for different applications has a different software set in it and that is what differentiates them. It is a well known fact that the VP in our trucks will flow enough fuel for at least 450 HP with electronic overrides, so the pump is mechanically capable.

well i guess i wasn't clear.....

See my wonderful idea is that IF the software limit in the VP in OTHER aplications has a HIGHER limit then OUR VP, then maybe you could get more fuel with our boxes then before. Rember that OUR VP will only pump out so much because of the software limit.



What would be great is if we could get the software for this, AND the ESDN software or that custom ECM.



Just a thought,

Andrew, do you expect all of us to do your own research?

here is a small list to wet your whistle.



BMW 320d,

Ford Focus td,

all Opel dti,

Saab,

VAG V6 tdi





these are high RPM engines... 4500 rpm+. . hmmmm what does that tell you?

Actually, starting in January, the VP44 pump WILL be going on 6. 8L John Deere engines, in order to meet Tier 2 emmission requirements. Also, on some models of 4. 5L 4 cylinders, a Stanadyne DE10 will be used. And even though Deere uses their own engines in almost all of their equipment, the indeed have used, and do use Cummins in a few applications. In particular the older 8700 series 4 wheel drive ag tractors (i. e. 8770) used a Cummins, and the current very large excavators (construction equipment) use a Cummins. Also, the off road articulated dupm trucks use Mercedes diesels, and the large dozers (1150H) use a Liebherr V6 diesel.

 

[LSMITH]

Andrew, you missed my point or perhaps it wasn't clear. The pump on our trucks is mechanically capable of making around 450HP, maybe 500. The major boxes that we have available are POST electronics, meaning that the CPU set limitations are not a factor. The EZ, VA, and others deal with the limitations of the CPU in the VP, but the Comp and Powermax etc do not. There is no more to get out of the VP unless you mod the internals of the pump to somehow get more fuel out of it.



EDIT: The fuel solenoid in the VP is the real limiting factor. It will overheat and burn up if it is run too hard, my GUESS would be that the VP44 will support 600+ mechanically if the fuel solenoid could be made to work harder for longer periods of time.

It does not work like that... the FPCM and ECM fuel maps HAVE to match. To my knowledge Cummins has all the FPCM's programmed the same... that is why they can program the ECM with fueling maps from 175 to 300 HP. The Chrysler application however may be a bit different.



when the limit is "removed" it will not make the fueling boxes work better... . the CPC type boxes would have to be reprogrammed to the new fueling maps... and since all major fueling boxes override the FPCM signal removing the "limit" becomes a moot point. With the limit in place we are still limited to about 350 flywheel HP using 275's and nothing else.



My Idea would be to use the VP-44's mechanical side off the ISB, but use an ECM and FPCM off say the BMW320D with a little creativity this would ROCK.



have you ever wondered exactly how the VR6 originated, and why it works so well at higher rpm's



Take a look at the performance options available in Europe for Vehicles using the VP44 injector pump... you might like what you see.

Just looked up the JD 6. 8L engine. To meet Tier 2 emissions they are is fact using the VP44... but it looks like the pump will not have bigger plungers since the engine ratings are 225 HP @ 2600 and 578 FT*LBF @ 1800..... but I will try to find out if there are any mechanical differences between the VP44's in the ISB and the 6068

I do work for Case!

starting this coming year (2002) Case will start using the VP44 in the Excavator with the 6B And also the 4B in the smaller excavators, backhoes, skid steers, and dozers
