8 cylinder P-pump on powerstroke.

[sfd823]

Got an extra engine laying around and wondered how possible it would be to put a 13mm quick delivery P-pump on a powerstroke. Haven't hardly looked at it, but I was told that the high pressure pump runs at half speed and has the same bolt pattern as the older engines with the stanadyne pump. As far as I can figure the biggest issue would be injectors. Any Ideas? Not sure if this is really going to happen, but 1000cc's of fuel would make a bunch of power.

These guy's have put a P-pump on a Powerstroke,just not sure if they have it running yet.

my suggestion was thread cummins injectors into our injector bores [img]/ubbthreads/images/graemlins/shrug.gif[/img] [img]/ubbthreads/images/graemlins/phoney.gif[/img]

Not to be the class idiot, but what is a p-pump? Piston pump?
1000cc's a squirt? Thats insane if thats what you mean. I assume you mean total. Our stocks put out roughly 95, x 8 and thats 760, thats not to far away. stage 1 bdp's 160 x 8 is 1280 thats more than that, I guess I'm outta the loop here....? [img]/ubbthreads/images/graemlins/shrug.gif[/img]

You mean like a radial piston pump right? I though about something to replace the hpop too, bud would have to fab something up...

Think a hyd pump from a zero turn mower would be a viable performance pump? Would have to figure out some sort of mounting and injection pressure regulation, but the ones I'm thinking of would have to flow atleast twice what the stock one does. They have four pistons with about 5/8" bore and about 1 3/4" stroke when the swash plate is a full tilt., or you could set a wheel motor up as a pump I guess too, they have a fixed swash plate, so you already have a fixed angle swash plate.

Way off base or viable?

[brahamfireman]

he is talking about the mechanical injection pumps, like on the cummins or the IDI's.

I thought it was 1000cc per cyclinder, I believe you can get inline 6 P-Pumps for IH's that are 600cc.

have to find a way to thread injectors into the heads somehow, fab up some lines. Custom Valve covers, run it at 1:1 with the cam.

Just remember that with a P-Pump on there it is no longer a Powerstroke. IDI. Might as well take an IDI, drop the compression ratio down to about the 15 range, find a different pump and run it till the crank blows. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

It's 1000cc's of fuel per 1000 injection's on one injector= one cc per injection. night not sound like much, but with enough air and camshaft it would make about 2000 horse. hypermax was splitting girdled, deckplated, filled powersroke blocks at 1800 horse.

[johndeerebones]

Holy crap. That's some serious horse for a p stroke to see.

No, the powerstroke wouldn't then be an IDI. The IDI uses a precombustion chamber, meaning the injectors don't inject directly into the combustion chamber hence the 444 DIT(Direct Injection Turbo). There is absolutely nothing wrong with a mechanical pump, ALL the johndeere engines I've worked on have one, some of the new ones have hpcr and stuff, but I have seen 15 to 20k hours of WORK on inj pumps if the owner treats his machine right. Granted the ip's are expensive to work on or replace, but our system is too. If it wasn't for having to do some major fab work and some serious head changes, I would be for that conversion, only reason ours may be better is with ADEQUATE hpop, theoretically sp?, you would have excellent atomization at all times, this is rarely the case with mechanical injection. That is the main reason for the push to HPCR and HEUI systems, better fueling, more complete burn, less emissions and noise.

Sorry guys, I must have my bs lips on, I seem to be rambling tonight...

A P-pump is an inline pump. Meaning it has it's plungers adn barrels in a line with a cam that runs under them that activates them. There are some HUGE P-pumps. We've had some huge 6 cylender ones that make 1,000hp in boat engines and some that are set up for 16 cylenders. There is a vast variety of them.

The pumps do run half engine speed. You could run it off the cam but you would need to design a completely new front cover to house the large gear to run off the cam much like the one shown on Wipe Out's web site. You could machine some plugs for the current injector holes to mount new injectors in and run the lines through the valve covers. However to actually make this work you better have access to a good machine shop and hopefully be able to do the machineing yourself because it is going to be EXPENSIVE!!!!!!!!

Sorry but I'm going to have to call BS on the 1800hp. There is no friggin way they were makeing that much power in a T444E. Show me some proof!

[andrew974x4]

hey guys, would it be easier to take a 7.3 IDI from the for sale section (pretty cheap) and set up a system like the 8 cyl p pump and then fab up a turbo system like 1700-1800 cfm range. then run huge injectors? i have no knowledge of the IDI, is the block any weaker? crank? does it use the same studs (main and head)? [img]/ubbthreads/images/graemlins/shrug.gif[/img]

is there anyway we could mount our trannys up to the IDI?

one of the advantages of doing this way is you could custom make your ouw intake manifold to work with the turbo and i bet you would see some good flow. [img]/ubbthreads/images/graemlins/wink.gif[/img]

thanks

[Dieselfever78]

I wouldn't mess with an IDI you will have rods scattered all over the place [img]/ubbthreads/images/graemlins/phoney.gif[/img]
BTW the pump on the IDI is a Stanadyne DB-2 which is a Distributor pump. They are capable of a few CCs of fuel also

I had talked about this before on the Bombers site last year. Threading in cummins injectors, and then using a 3408 fuel pump, I got laughed at.... Anyways that pretty much takes the oil problems a PSD has away doesn't it? With the type of power a cummins can make per cylinder a powerstroke could make some serious power as well. Couldn't you remove the HPOP and put the fuel pump in it's place, I know some mods would have to be done.... but hey that's what this is all about right?

[andrew974x4]

heck, a couple years ago most people would have laughed at you if you said that we should stick two hpop together [img]/ubbthreads/images/graemlins/grin.gif[/img] now that is has been done and helps performance, people think why didnt we think of this earlier. but im sure there was alot of R&D involved. this setup would proply take quite a bit more. but no more 2000$ oil pump, 2000$ injectors, 3000$ rods...blah blah blah. but then our powerstroke is just an 8 cylinder cummins [img]/ubbthreads/images/graemlins/phoney.gif[/img]

Wouldn't you still need some big rods if you did this setup and were making any big power? [img]/ubbthreads/images/graemlins/confused.gif[/img]


This is an interesting idea.

[andrew974x4]

no, with that pump you could fuel at way high rpms and with making hp higher in the rpm range (4500-6000) rpm there would not be an increase in cylinder pressure....or at least thats the decision we came to on the 4000 rpm forum a while back [img]/ubbthreads/images/graemlins/shrug.gif[/img]
