Modded CP3 Information Update

Challenge for aftermarket companies

Just to clarify this for myself and others, at idle the fuel pressure is similar to stock, right? It climbs up like stock and stays up instead of falling off like the factory pump does? And my final question is the rail pressure cap, does it close the rail pressure port completely or does it raise the opening pressure to a higher point? What is the next weak point if it is closed completely? Could you PM me with a stage 1 price?

yes we have injectors to match you HP output level, yes you will get a price break. TDR member? remember that at stage 2-3 we are having a hard time finding air to burn all this fuel, stage 1 is for most and it includes the rail cap--- so you wont bust a valve and be down and out, it is the easyest and the safest way to do it, not mention most potent!!!! :--)



Why do you need a plugged relief valve? 20k should not blow the valve open, so the stock one would work right?



I know you cant tell how you get constant pressure, but can you say if it is the same as that one place that is making a new gear cover and just turing the pump faster? OR are you internally modifing the pump to make it better?

If your pump goes to a minimum of 20000 just after does the injectors rattle much more, I'm talking about noise. What do you think would give first without a rail pop off valve if pressures were to hit maximum?? How does this work, do we pull our pump and send to you or do you have them in stock, if we have to send it to you what kind of turnaround can we expect? If I understand you correctly, the minimum pressure we will see under full throttle full load even at low rpm is 20000????



not noticable difference on noise. yes the injectors will be stressed the most any thing over 600HP i recommend better nozzels or injectors,we have pumps ready just send the core when you are done. about a week to get it. thats right after idle and no relief valve you will see consistent pressure of 20,000psi and greater, not to exceed stock limits w/ stage one. its still controlled by the ecm, ours just has ability to push alot of fuel volume at once where the stock one cant!!! :-laf

yes it climbs like stock but w/ more psi per rpm range,yes the relief valve is deleted, and the next weakest link is the injectors, w/stage 1 you really dont have to worry!!! :-laf

20k is not the max the system has to offer its the min it will still peg the 26700 w/ abox. our railcap eliminates that posibility,we are internally making all of the delicate orfices better to offer more pressure sooner and consistent!!! basically you are no longer limited by the cp3 but the ecm is another story after a certain rpm the ecm cuts fuel. :D

If I read that right, Your railcap eliminates the possiblity thats it will peg 26,700 with a box?



But what if I dont run a box that wants 28000? Are you saying I NEED the railcap to make the modded CP3 work properly?

im sorry if i did not make that clear, i've had so many people to talk to today.

the railcap eliminates pop off all together at any psi! no you dont need the rail cap but if you want unlimited power you will, the cp3 is only good for the pressur it can hold and a stock rail valve will go any were from23-27k psi thats just a $3-400 bill i dont have time for and it makes diognosis easy, the injectors is all you should worry about on stage 1 or 2. so yes you can use the stock rail valve but you will most likly lose power that you could otherwise use!!! thanks :-laf
 
Can the pressure relief cap be bought by itself or is that not a good idea to put the kind of pressure on bone stock injectors. If that is possible please PM me a price on the cap.
 
remember that at stage 2-3 we are having a hard time finding air to burn all this fuel,



I've got a set of little Twins that seem to burn fuel ok... :-laf Just watching the thread.



Jim
 
Very interrested. Please quote me prices on pressure relief cap, stage 1, stage 1 w/injectors and w/cap, and stage 2. Will twins provide enough air for stage 2 or is stage 1 sufficient enough for twins.
 
From reading through the posts in this thread I think there is some confusion as to how exactly this pump operates.



From my understanding, this pump (stage 1 for instance) will behave just like a stock cp3, but when the truck is under load, from just off idle to redline, the pump will not lose pressure due to the long duration of the TST on a high setting or large injectors. It will not be able to be drawn down to less than 20,000psi under full load, where as a stock cp3 would lose up to 12,000psi of pressure under the same conditions (TST/injectors). Your CP3 has many internal flow enhancements that increase the flow volume thus allowing the cp3 to maintain the 20,000psi with less work. Am I understanding this right?



I think the "consistent 20,000psi... from just over idle to redline" and "20,000psi is minimum after idle" statements have a lot of people (including myself) confused. Please clarify it for us.

the 20,000psi is minimum after idle... ... .

Ditto what Jeff said. I'm still confused. In the reply above it still sounds as if I was tooling through a parking lot at light throttle, 1,000 RPMs, at 35 mph, that pump will be putting out 20,000 psi. :confused:

how many pumps/sets of injector sets have you sold? sorry, just don't want to be a guinea pig



about 15-20 units have been sold in two weeks!!! also NADP's barry voltner has had one on his truck for over 9 Months===serious abuse and no problems, the mods will give you the same if not better reliability cause its alot more efficient.

yes to your first statement, and the 20,000 is a min under aload and starts right after idle, once you get to 20k it will not drop off untill red line sorry about the confusion! the rail will have more rail pressure at a given rpm due to not having a rail valve, just not 20 k at idle like you are thinking sorry. :D

its just like stock but it wont drop off pressure once it does make it, you wont cruise at 20k---that would be bad!!!!! :D
 
the reson im saying 20k after idle is cause under full load we are see ing about 20k as early as 16-1800 maybee alittle sooner, and that comes very fast!! :-laf
 
When you are on stock fueling (no boxes turned on), will the CP3 return valve be able to get rid of all the extra fuel that we are not using, keeping rail pressures at a respectable level? What would the max rail pressure be at WOT with stock injectors when not commanding something higher than stock with a pressure box?



Are you offering a warranty with your pumps?
