Modded CP3 is on - Dyno and review:

[Tomeygun]

Tomeygun made an additional 100hp with just 13psi and stock injectors right up to the point where fuel pressure dropped below 10psi.

you know... Don M mentioned that I might have found the limit for stock injectors, But I think I have saw higher numbers from stockers, So i dont think that is it.



BTW, What IS the highest HP on stock injectors?

 

[AK RAM]

I guess the only question I have left is: When running a FASS 150 with this Cp3 at 40psi, how much does the fuel pressure pull down at WOT?

As Richard suggested (off-line), maybe you found the limit of duration. The fancy Cp3 is not going to extend that limit for you. Maybe turn that TST down a little and add a bigger squirt at shorter duration... i. e. time for injectors!! Oo.

tommy i dont think you have to do alot of testing just get the walbro 392, a couple of tapped banjos,regulator, fuel line, dodge wire harness relo kit, and set the regulator until it is where you like it. the walbro has 80psi all the time when you set the reg at 40 you still have another 40 backing that up. as far as flow rates bla bla and all that we have hashed that out a hundred times and it seems the little cheap walbro is pounding the golden boys (fass) teeth in! for those with $600 to buy a pusher pump... ... hmm moma told me not to say everything i think so i will leave it at that.



one analogy that comes to my mind is :walbro is to fass as a homeground 0 plate is to the $200 0 plate (b/c it was engineered)



Tommey do you have the double disk in that bad boy yet??

I hear ya, I know the 150-HpFp is on its way soon, I'll test it first, But I might have to pick up a Walbro from Gypsyman and give it a whirl...



As for the DD clutch, Sadly I have not slipped my OFE. . I know,I know, I called peter and told him he must have miss-labeled this clutch... (only suppose to hold 450hp) - and it DOES hold on the street , never towed with it though...



I hope I do slip this clutch with the new pump, It'll let me know somethings better then

I wondered the same thing about these clutches. I guess the tires break loose before it does any damage to the clutch.

If you guys want your clutch to slip let me pilot one of your trucks through a sled pull.

Watch the sparks fly!! :-laf

550-600 is the most i have seen on the stock injectors

about 10psi max

Oo. the cp3 will give you more volume at any duration or timing, pressure event over the stocker anyday of the week----so it will extend the limit, to a point, and yes there is only about 50hp or so left in the stock injectors!! so you should need injectors soon enough :-laf

Why are you guys using the modded banjos instead of an style fittings? I haven't done any testing on my 3rd gen yet, but on my 2001, I changed the banjos out to an fittings and my fuel pressure stayed more consistent. With the banjos I could pull the pressure from 18 psi to 10 at WOT and with the an fittings I could only pull it down to 14 and it quickly recovered back to 18. That was on a 608 hp truck.

That is a great questions, one I do not have an answer for...



How much work is it to switch to all AN style fittings?

And that means all new lins right?



BTW - I called GENOS garage to order large banjo bolts and the guy said not too, it would not help... that was weird

 

[lmills]

I run all JIC/AN fittings on mine system. From tank to CP3. The only tapped banjo I have is for running fuel back to the return line. If I would have had more time, I would have ran the line on back to the tank all together. That might be next weeks project. Right now, It isn't a necessity.

AND you've got some pretty stout numbers, Could this be the next big mod? Removing all the Banjo connections?



Lmills - Where did you get all the nessesary fittings?

 

[Gypsyman]

I'm sitting just the opposite. I layed my numbers down on nothing but drilled banjos and stock lines. Strange how different all of our trucks are depending on how we make our power.

well hmm, I was thinking if I need larger banjo bolts, Heck I though "it can't hurt" - I think the guy at genos just wasn't in the know...



What size did you drill them too? (you did them yourself, right?)

 

[Gypsyman]

I picked mine up from Geno's way back when I first took delivery of my truck. I'm having some built from stainless to keep in my inventory along with some other fittings.

 

[CRiggan]

Does anyone have the CP3 stage 2 ?



Will it be a daily driver type pump as far as injector, rail, and engine longevity?



Even if I did not use it to its potential, I wonder would it be better money spent on the cp3 or elsewhere.



just thinking on line !! LOL

 

[CRiggan]

Forgot to add,



Does anyone know how long it will be before higher pressure rail relief valves will be offered? and What pressures would be available. Im not too sure about the rail cap. I was thinking a 32,000 psi rail relief valve maybe a good option but how much does it take to crack the injector bodies? and how much does it take to crack the nozzles?



I guess it goes hand in hand, If we would want to sustain higher pressures our injector bodies, and nozzles would need to be up to par.

 

[Diesel Power]

yes the stage 2 is out there and it is streetable the rail valve and electronics will be out in a few months. thanks Oo.
