Dual CP3's available next month!!!!

I too agree with that statement 100% Todd. The point I was trying to make was not to discredit flow volume as it should be priority one. Without that pressure is meaningless. What I'm saying is we need to keep a volume moving through the system. To enlarge a reservor in the middle that really does nothing more than act as a distribution manifold should have little effect on your end goal.



If the problem really is between the CP3 and nozzles, resistance to flow is what we should be looking for, not static volume for fuel.

i also agree with that

Your right on,The problem is the Cp3 is dependent on rpms and the injection system is not. The rail is more limiting than one would think it to be.

Hey I'm all for hp from an easy R&R on a part. I will look forward to some reviews, etc

Who ever said "once you fix one problem in the common rail system you discover 3 more" hit the nail on the head!



At first we put pressure boxes on the increase fuel to the injector. We had plenty of rail pressure so we move on to the next problem.

Then we increase duration and add larger injectors, but now we drain the rail and lose pressure.

Next comes the modded CP3 and dual feed line in order to restore the rail pressure we had once lost.

Reb. B stated that he can increase duration while maintaining rail pressure yet experience no power increase. There can only be two reasons for that. . . either not enought air(entirely different subject there) or that there is not enough flow through the injector tube.

I. I. is already extrude honing injector tubes out by . 100 and increasing flow to the injector body which is where we are at now.

You can either jack the flow coming out of the CP3 up even more (dual stage 2 CP3's) and have insane pressures running through your injectors and take the risk of damaging them or design an injector body that flows more through it.

Of course once we make a larger injector body that flows then the rail starts to drain and we find yourselfs on the PPE website ordering a dual CP3 set up for $4,000.

The two main issues that we face are how fast can we get fuel into the rail (CP3) and how fast we can get fuel out of the rail (injector tube and body).

Having a larger resivoir (modded rail) of fuel on tap will only help momentarily and only if we can get the fuel out of the rail fast enough.

The powers that be have figured out how to get fuel into the rail and now we just have to figure out how to get it out.



I realize that i am only a redneck mechanic in the Gold Mines of Nevada and that this is a very sophisticated system but that is my take on it.

 

[TCDiesel]

Yep, The mild rail is only a link in the chain,it will extend the stock Cp3 capacity only to a certain point (with/without upgraded lift system). It will put the Modded Cp3 into areas unexplored. Again I cannot over empathize that everyone will experience different results do to setup,the Mild rail at $150. 00 Plus S/H is well worth the cost. . (your core) If new the price will triple. . Well since our company banner is flashing I hope I don't get in to much trouble for the post of the cost.

How much bigger is the mild rail? IS there a was to measure the internal volume before and after?

 

[TCDiesel]

The Goal was 50% intake and holding capacity and was achieved. What we did was measure Before and after. @ 10. 000 Psi it was too dangerous after that, that was our test facility Max. So I won't post exact numbers. I don't mind sharing Product info but technical info has limits. Some of the other companies are being jerks about this, all this does is makes me won't to but more effort in and even lessen the cost.

On the subject of the PPE dual CP3's, this kit is very nice. The pics on the site that Justin posted are from my customers truck. I have been driving it the last couple of days and it seems flawless. We are working on more agressive fueling now, but with just a TST and BDDL, adding the PPE kit was very noticeable. We should have these available to ship very soon too. I will keep everyone posted on progress as it comes.

I have did a nationwide search and found One rail in Texas $260. 00 used. New $425. 00 and None available at Cummins Part # 3957077, DC Part# 0445226014 ,I can only imagine what DC cost is. Please contact us if you know of anyone with available rails. At this Point the only option is for you to send us your rail for modding, I have no cores left.

I have been keeping an eye out for sure. I actually had one earlier this year but traded it off for some work/parts



So have you had any failure rate due to removing material from the inside of the rail?

 

[Bob Wagner]

I have one 6. 7 rail with all the lines. whats it worth? just curious

I don't know what a 6. 7 rail is worth,I'm surprised you even have it.



Tommeygun. None.

Good to hear. I have already contacted the guy that has my old rail to see if he will sell/swap it back -- For $150, I dont mind giving it a shot.



You know me, I love before and after dyno graphs :-laf

 

[JStieger]

spare rail

I have a spare rail in my parts stash...

 

[TCDiesel]

PM me the cost,I'll take it.

What numbers have been seen with the dual CP3's?



How many have been installed? What problems have been seen ?
