Cp3 Info

Tommy did gain, but it wasn't peak hp! I'm definately interested to see how the injectors and new lift pump work out. Lee.

tick,tick,tick,tick,tick,tick,tick,tick,tick,tick



Just talked to Don M, he said he's waving 7 secret herbs and spices on my injector tip as we speak...



I feel like a kid on christmas eve!!



BTW - do you have to rub it in? -- also I'm thinking that old pump was toast, it was way louder than the 150 I just got done installing

if you go to the reaserch and design section of tdr, there are pages upon pages of cp3 info in them---these and other related posts have been posted. just in case you did not know :-laf

Well... Yep, I'm new here. This thread has taught me a few things... 1) I think I'll keep my '05 stock and enjoy it for its refined state. 2) I'll pick me up another 94-97 12v to play with. Maybe I'm old fashioned? Maybe I'm just dumb? I'd rather build power the old fashioned way, tinkering with mechanical things... . just seems like cheating pluggin' in a box and presto... . ~150hp! Don't get me wrong, the technology is incredible! IMHO, plugging in a box is similiar to a ricer on Nitrous. I'm really not trying to offend you guys. I realize that there is much more to it on the 3rd Gens to really make the hp.

how is there any difference? You do pump work to a 12 valve to get more power, we do pump work to get more power. You change injectors on a 12 valve, we change injectors. You adjust the timing on a 12valve, we don't have that luxury, but we have a box that does. So how is it that much different?

In MY opinion both Floor-it and Relentless have products that will have advantages over what guys are currently using. Both John Isaacs (Floor-it) and Chris Strickland (Relentless) are extremely sharp and honest guys.



I feel that these two products have been put up against each other because of a certain salesman that is just trying to push product before there is the proper information that the Diesel owners need:



What fuel pressure is needed?

What volume is needed?

Do you need injectors to get the proper gain?



As far as I know none of these questions have proven answers. When they do then we may have something. But I do thank guys like tommygun for trying to get everyone the answers.



Remember that these two companies set-ups are nothing alike, one company is modifying the pump the other is playing with the speed. I also disagree with DIESEL POWER saying that Relentless Diesels set-up will fail faster, is there any proof to the claims that it will fail faster NO, so I feel that point should be dropped. Again just a salesman try to sell products.



Relentless Diesel's set-up right now is making big power and that's great, guys just need to keep in mind that it's a tougher install, but the results seem to be worth it.



I feel that the Floor-it stage 1 set-up would be great for the towing guys or the guys that have big chargers that need quicker spool-up. The big power guys will probably be looking at the higher stages of Floor-its systems in MY opinion.



I think it would be awesome to see a truck that had both set-ups on it. Actually all this talk really has me debating getting a 3rd gen and doing exactly that.



I am friends with both John Isaacs and Chris Strickland and it's crappy that some salesman is having these two products put up against each when both guys feel the others set-ups are a good product. In a perfect world these guys would work together and we the customers would get an ever better product.



There I put in my 2cents worth.

Why not over speed Floor-it's pump using Relentless'es pump cover and gear? Hmmmm. .



This aint no kids game! Lets Git-R-Done!

Chris and scott have talked, I've been out of the office, and this is going to happen. We at Floor it Diesel plan on working with chris to show the benefits of both products!

I cant wait to get in on some of that action.

Amen to that!!

Floor-it and Relentless together, this is gonna be SWEET. I'm gonna get a 3rd gen.

John, pretty soon you are going to start putting a ~ after your name. You are impossible to get in touch with.

 

[GWoody]

Oo. I know, I've got Floorits cp3 stage 1. 1 on my truck, I volunteer to be the guinea pig, I won't charge a thing if relentless wants to put there mod on my truck! Oo.

I know lmills,

I've got alot of personel things happening this next 2 weeks but after that

I hope my time will free up a bunch, sorry guys.

all that, and then some special sauce Oo.

Interesting info. Couple of questions to understand the cp3 more clearly.



1. In the diagram is the “Internal Regulator” the COV?



2. Is the COV basically a spring loaded two stage relief valve?



3. Would it be more accurate to show the green line from the gear pump to the FCA and have a tee in the line going to the COV or does all the flow actually pass through the COV?



4. The 2005 factory service manual states the output of the gear pump varies from 80 to 180 psi. Is this pressure measured before the 0. 110" orifice?



5. The diagram shows the excess flow not used by the FCA or for lubricating the pump being returned back to the gear pump inlet instead of to the return line. Is this really the case? If so what happens during high rpm with no fuel demand by the engine?



6. When the FCA limits the fuel to the plungers, what keeps the pressure in the partially filled plunger chamber from dropping below the fuel’s vapor pressure at the end of the intake stroke?

That's what I'm talkin' about!! The best of both worlds,... ??? :-laf

Nothing. It cavitates, then re-compresses what little fuel is in the plunger.

Bosch discovered that it takes a lot of energy to generate 20000 psi, so they minimize waste, and that's how it's done: by starving the pump of fuel (as opposed to dumping excess high pressure fuel).

The only reason why the pump can go bad if it runs out of fuel is that it needs extra (low pressure) fuel for self-lubrication and cooling.

Thats surprising, given all the harmful effects from cavitation. I figured the plungers may float in the cylinders and the incoming fuel pushed the plunger back only as far as the quantity of fuel required, or something along those lines.



Anyone know the answers to the other questions?

the plungers opperate just like valves, they have a cam that opens and closes them and a spring that will assure it closes. Oo.

cp3 Problems???

Just pulled out the driveway got 1/2 way up the street and the truck died/ no cough, no smoke, engine just quit/ have 04. 5 3500 srw 60k completely stock/engine turns over but no fuel out the exaust smell, ie no fuel to injectors/ drained fuel bowl, refills quickly from LP/

removed the banjo cap bolt from the top of the common rail and cranked engine, no fuel spilling from rail/

Is there a sensor or valve that closes not allowing fuel from the filter bowl to the rail?? Is there a way to inspect if the gear pump cp3 is spinning when the engine is turning over???

If it is the cp3, whats my best option for replacement,rebuild or upgrade??TIA

Did you replace the fuel filter?
