Dual CP3's available next month!!!!

[Luken]

I heard 2 cp3 pumps are no good all you need is 1 cp3. 4 ! :-{}

I wonder who told you that... .

My guess would be someone who is making a killin off of a $5,000 pump :-laf

I would wait until more of both are out in custoemrs hands...



I only know of one customer owned CP3. 4 - And thats a 2003 SO engine I think the guys name is Kerry - And I have not heard of that truck making any crazy hp numbers yet...

i agree, lets look at the new 6. 7ltr and what is the first thing you see, well i see bigger lines, and a much bigger rail, not to mention a bigger cp3, and a bigger relive valve. i will say this i saw this a while ago and i am in the works of making 2 projects, one with a retrofit 07' fuel system and the other will be a duel rail bigger line setup from our trucks. that i think is where most of our problem is.

So why couldn't we modify these parts to fit the 5. 9??

Sounds like a plan to me!

You can Modified your own rail,I would encourage you to do so,Just Make sure you have a stock replacement available. As soon as you mention to the shop that is doing the work that it will see 25,000. 00 PSI plus. the expression on the his face will change.

Reb. B,I concur with you their are so many unknown points in the injection system in CR where to you begin. as soon as you tackle one problem three more develop.

EXACTALLY!



A few months ago there was a thread about dual cp3's and the only people one there saying that it was a stupid idea, were convientally the ones selling "modded" pumps.



For every "know-it-all" that says dual pumps don't work there is a HUGE list of D-Max's proving them wrong. I could have dual pumps on my '05 dodge in a couple of hours, we have all the parts just no spare time. By the way, all the parts including the extra pump is no where near 4k. :-laf

i still think that you are are going to be missing your target. The real problem is in the inj. body itself. Get this, ... not sure what to make of it, but when increasing duration, if you go pass the sweet number, pressure is still there, but the HP numbers fall off. Not sure if too fuel is the problem, or if the extra fuel is getting there too slow, or the problem may be elsewhere in the motor. Maybe the fuel is at lower pressure at the tip than it is at the rail? I don't no, but i think that these probs have to be figured out first. I thought is do the easy (cheap) things first and see if it helps or hurts performance. After a certian level in horsepower, the top end number gets harder to get, but the mid range power goes up like crazy.

i think you have a good point

I took a couple of minutes (hours really) and read up on the HP numbers the Chevys are putting down with the PPE kit -- :--)



I can see why alot of puller Chevys run the Dual CP3's



I will be keeping a close ear on the ground on this one... .

And they also have two rails to feed for that system while we have one... . for now that is. Like all systems, the largest flow(volume) is limited to the smallest orifice. Twest I have been keeping up with your post on the modded rail since I also know that the stock rail is a limiting factor.

your right, if you do the math on what is demanded and what is avalible the modded cp3 should be able to produce between 8-900hp, but thats by math. also the restriction becomes the rail, and the fuel lines, they are needed to double in size for them to flow the amount of fuel demanded to make that power on diesel. math gave me this answer again. also look at the new 6. 7 cummins every thing on it's fuel system has doubled, i need to get back to work on this Oo.

 

[NPloysa]

So who holds the most power with a stock CP3 and what are the numbers? What about the modified CP3s? I am talking about Cummins trucks. How much more power do the dual CP3s net the stock/modifieds?

I made the numbers in my sig with a stock cp3 and stock injectors... . on #2 only



659. 3 hp 1534 tq #2 uncorrected - stock cp3/injectors

 

[Reb.B]

i made 807 with stock cp3 in Fresno. it was pretty radically sounding though, . . i made consistent 770's with the stock cp3

 

[Reb.B]

but its not really about the dyno power though. power on the dyno vs. consistent, long power through the power band CAN be two different things. The modded cp3 helps with lengthening the power band when a load is applide.

Is this why a modded cp3 helps so much in the 1/4 mile?

 

[Reb.B]

in my opinion yes. Also, if you are losing rail press, this will dramitacally help EGT's.

reb.



I guess no one told you that 03/04. 4's cant make power :-laf

 

[MCummings]

I think that there will be some part swapping going on...

with the injectors I have are way too big even for a stage 3 cp3 and many people i spoke to say say that dual cp3's are still being run by wire slit into 2 .

not saying that the dual setup is not better just saying its not working proper. . I could be wrong !! I just take what I hear and make up my own assumption... and for a stage 3 I drain rail pressure on a hard run . . fact!

if your draining the rail with a stage 3, then something is wrong. i would double check the pumps volume.



i am working realhard getting this new fuel system to retrofit our trucks, along with the modded relife valves, it's not easy
