[SRadke]

I would like to recognized this as my first serious post, yehawww! Oo. :-laf :--)

So as of right now you're 1 for 185. Sounds like good odds to me I do enjoy the not so serious posts

Ok, I’ll try……… The pump criteria is complex. It’s base from all the ISO standards (temp, injector, lines, fluid etc,) The flow duration is measured from ISO injectors opening a 1000 times, each will be tested then, an average percentage will be established for your cc.



mayby some of the SME's (subject matter experts) can elaborate... ... ... ... .

We have an old pump stand that we use for our old tractor pulling stuff. . We normally set the pumps with the Stands injectors... then we use the injectors that are going to go in the tractor. . and fine tune the pump with the actual injectors to get them as even as possible. . then just keep the injectors in order... This maybe overkill. . but it works for us...



Using the Stand (or standards) injectors on the stand gives us a base to compare different pumps output...

Thanks !!!!!!!

As long as we're on the subject of pump output..... What do our trucks put out of lets say a stock 180hp pump when they are maxed out..... and what does it take to get to where lets say Kent Crowder is at? 450cc's stock, 600cc's for Kent?

It's possible to be in the ball park of 450-500cc's with a 180hp p7100 with custom camplate and dv's without changing out the cam, plungers and barrels .

700-900cc's with custom cam, 13mm plungers and barrels. Comes down to how much money and time you want to spend on the flow bench with a good tech.



Kent's pump wild guess 2000cc's. Mind you it's not a Dodge/Cummins p7100 either.

I have seen A pumps with 13,14 and 15mm plungers for sale... and then go on to a P pump. . or a Sigma pump... Cha-ching... $$$$ Mark said it...



Check out the pulloff.com Add page sometime. .

Holy cow!!! 2000 ccs!!! What pump do you think it is??



Is it fair to say 1cc per HP?

Gene,

It's a wild guess, but it doesn't look like 1400-1500cc's if you base 1cc per hp for burn. I do know it's not a regular Dodge/Cummins injection pump that's been modified. How many cc's do you think he's running?

 

[mfunderburgh]

I'm with gene on the 1cc per hp for kent. So that's about 1300cc's-1500cc's i guess, with an a-load of water on top of that.

 

[Sled Puller]

Well, I know its not a 7100, and as a totally ignorant guess, I would say 800-1000 ccs. ( Real ccs, not stoopid pump imaginary ccs. )



I don't know about the 1cc per 1 HP, I just popped the pin and threw the grenade into the room, and waited for it to go off!!!

 

[nascar mark]

Gene,

What do you call real cc's ?



Imaginary cc's I guess it was my imagination working overtime when I've seen our stupid pumps putting out over 700cc's per 1000 stroke on the test stand. I must have really been halusinating the day when one did 900cc's with a few more tricks.



You need to stop smoking our good B. C. bud.

 

[Sled Puller]

I would use CDS as a "standard" cc chart that P-pumps are capable of.



1300cc 13mm 6 Cyl.

1100cc 13mm 6 Cyl.

800cc 13mm 6 Cyl

The Sigmas start at 16mm.



And I don't think you guys are there yet, with, "a few tricks. " Nothing personal.

That's a little low in my case. I'm @ 448ccs ... thanks to the PDR pump shop.

I saw a Piers Stupid pump put out 732 ccs. The same day mine did 616 which was up from 465 when it was just balanced stock.

 

[Sled Puller]

616 ccs, and you are making almost 600 HP?



Pretty dern inefficient, last time I checked, I was at 320 ccs, and 575 HP!! LOL! See what I'm talking about?

 

[Sled Puller]

which was up from 465 when it was just balanced stock.

465 ccs stock 913? No parts changed? What rpm did you test it at?

 

[drawson]

The 465 was tweaked by a local pump guy a couple of years ago. Now 616 is by a killer pump guy in SLC. Geoff Injection service, The 598 HP was with a hole in the intercooler and only 43 pounds of boost. I have done 672 HP(@ 65 PSI) but I had no Diesel guys there to witness it, Only poor old gassers.



Gene, Oh yes one more thing I still have Dyno Oil in it one more oil change and then I put back in the good stuff

 

[Piers]

You can put in massive amounts of fuel & not get the hp you want for lack of air to burn it all. Prime example, my old 94 truck in valet mode put out 325 cc's and 520hp, flip the valet switch off... 700+ cc's, but only 700hp.



If you build it right [none of us do... . cept sleddy, he's a legend in what's left of his own mind ] you should be able to produce 1. 7hp for every 1cc of fuel, course it's a lot cheaper to add more fuel than build it right, so that's what ends up happening.

 

[J.R. Adkins]

1. 7 is what I have found to be true.



Gene it looks to me buy your numbers you are closer to 400cc's delivered and burned. Hey hows that schedule coming along?
