Modded CP3 is on - Dyno and review:

[Tomeygun]

Tom, Hopefully you are right!



That would be something else to see the HPCR's out doing the P-Pumper's.

So,,,, When are we getting bigger rails and lines? heheh



Merrick

I'm not gonna say I put my hands on a larger rail and line kit... . BUT I'm not saying I didn't



hahahahahaha

Is it possible to upgrade the 3/8 hose from the tank to the fass 150 pump and from the fass to the cp3 to 1/2" hose?



Will this create cavitation? Should I use a larger pickup pipe in tank also?



Everything with the fass150 is 3/8. Thinking the stage1 pump could use the extra fuel in the 1/2 hose. What do you all think?



Thanks for replies, looking to supply a stage 1 cp3 and stage2.

I thought the 95 came with 3/8" while the 150 used 1/2"???



That's what I was told by the dealer that sold my FASS95.

My 150 has the 3/8" line.

 

[CRiggan]

My 150 FASS has the 3/8 line, im wondering if More fuel volume in the fuel line at 1/2" would help keep the cp3 supplied with fuel or will it over work the fass 150 pump motor when trying to supply 40psi all the time at 1/2" instead of 3/8"



Thanks

I don't think you would need to worry about the line size... like I asked earlier, are the fittings in the modd'd CP3 enlarged to allow more fuel?? You could put 5 inch lines on it, but if the fittings are still only 3/8"... well, you get the point.



As for the FASS, it is simply going to flow 150gph "easier" through 1/2inch line (the pump would then become the limiting factor, not the line)... the pressure valve still determines the amount of pressure the FASS holds... that pump flowing 150 gph against even say 0psi is going to be happier than flowing 80gph at 40psi... the pump would essentially have no load on it at 0psi.



To make it simple, the FASS is actually working less the more fuel you use at the IP (you are taking some pressure from it).



I know they told me you can get 1/2" line with the 150... maybe it was an upgrade??????????

Oo. we have bigger lines and rails being manufactured as we speak----can you say WOW!!!!!!

 

[mattymac]

Now thats what we like to hear!

 

[CRiggan]

I did receive the larger banjo bolts from city diesel yesterday. This should help some I guess.

 

[Diesel Power]

see we are not offering a substandard system, this is a complete fuel system for the serious diesel guy, one that has been seriously tested and matched---that will have the ability to push 3rd gens in the mid 1,000HP range, no problem Oo. ---none confirmed yet but i would not put it out of the question---this is the reality of modern diesel technology. thanks

Steve you are so correct.

Ive read this entire post and I am confused. I do not understand all the talk about rail pressure caps,30,000psi,and what not. Congrats to tomeygun for buying a new product and informing us on it. What exactly is the stage 1 mod?What is the stage 2?I have a cp3 mod that made 86rwhp and it maintains factory rail pressure and you dont have to put your fass into hyperdrive. To back up my hp gain Relentless Diesel just put the same package I have on a 06 mega cab. After getting a baseline with the twins and tst,the cp3 was added and the truck picked up an additional 96rwhp for a total of 682hp. How does getting the fass to put out 40psi help the the cp3,the reasoning for the pressure increase I am guessing to to assist the gear pump on the cp3 put more fuel out?The internal pressure the gear pump makes is in the 70-80psi range,why not feed it with 80psi?

 

[MFalkinham]

Steve you are so correct.

John

I agree, and feel he's right on. I'm confused about why some people seem hung up on attaining a "high PSI" from their lift pumps. For example, if you look at the flow curve for a Walbro pump, the higher the PSI goes, the lower the flow volume becomes. In that case I'd rather have the higher flow than higher PSI any day.

Seems to me the main problem with the stock lift pumps isn't with their low PSI, but with the limited flow volume that they are able to supply (and their weak design which results in premature failure).

[Jeff_K]

You are right Mike, the increased volume is important, but as John stated in an earlier post, increased suction pressure makes a big difference on the stage 1+ pumps.

... . while volume is important it's the pressure that is more important due to the passage design's of the pump. Increasing psi on a stock CP3 will only gain a very small amount, but when you combine with our stage 1 it DOES make a difference... .

 

[MFalkinham]

You are right Mike, the increased volume is important, but as John stated in an earlier post, increased suction pressure makes a big difference on the stage 1+ pumps.

Gotcha, thanks for clarifying that, Jeff. My brain was stuck in "stock CP3" mode.

 

[Blacksdieselhp]

so back to an earlier question, is the inlet of the modded cp3 enlarged or is it still the same? No need to run big lines if its the same.

I admit I was unsure if to start this thread well knowing I did not keep up my end of the bargain with the fuel pump requirements which have resulted in IMO a HP number that could and will be better as I address said FP issues.



I had been shopping around for some time for a Cp3 mod, and the reason I did not go with the relentless diesel mod is due to when someone comes out with an RPM program, I do not feel the relentless-modded CP3 will handle 4500 rpms plus the overdrive of the smalled gear. That would make the CP3 run as if at like 6000 rpms. I am not sure that it can handle that rpm.



Then I would be stuck with a CP3 that cannot take advantage of higher RPMs which are needed with a sled pulling truck. As far as putting your FASS into hyper-drive, I intend to test that info with a multitude of tests with bypass regulators, etc, etc



I am certainly happy to see more than one company making CP3 mods. I think both CP3 are great, and customer will be able to chose based upon future plan and usage, etc...



BTW - yours numbers, geesh - slow down we need time to catch up!

It seems a 500hp 3rd gen truck is so common in todays market... I remember back when I bought a 35psi boost gauge, told myself I would NEVER go over that, HA, right... .



PS - let me add that one of the first truck for has this stage one picked up 8 tenths on the 1/4 mile ( 13's to mid 12's). Anyone around drag racing knows thats like a 80hp gain on the motor. My point is I fully intend to make a 600hp pull on january 1st when I get my 150HPFP with bypass regulator. (I just may bring some "turbo in a bottle" -- Just in case :-laf )

so back to an earlier question, is the inlet of the modded cp3 enlarged or is it still the same? No need to run big lines if its the same.

What you can see, looking down into the inlet…it is the same.

 

[AK RAM]

I'm sure John has tested this pump thoroughly and knows for a fact that max power is made by the Cp3 when fed with 40psi. However, with Tomeygun's steady linear HP rise on his dyno sheet even as his FASS pressure was dropping all the time, I would bet the amount of power lost between running 40psi and 30psi is almost nothing. You could see it on a dyno I bet, but would never notice it anywhere else. Tomeygun made an additional 100hp with just 13psi and stock injectors right up to the point where fuel pressure dropped below 10psi. If you could just maintain 13psi at the inlet and had a set of aftermarket injectors, could you imagine the HP gain you might would see? I'm thinking 40psi for max benefit sure, but anything 30psi or above would probably water your eyes.



One thing to note, I talked to Rip today about FASS upgrades and for those with a full FASS 95 like me, the new brushless FASS motors do not fit on the older FASS filter base. If you have one of the pre-brushless motor FASS units, you will have to purchase an entire new FASS system to upgrade to the brushless FASS 150. However, I'm sure there are plenty of old noisy FASS 150 motors still in stock to cover warranties. So you always have that option.

Review - second time around

Ohh yeah, Almost forgot:



review after a couple days is that it seems now when I hammer down, The truck pulls right from the git-go. Even through the spool up process, the truck feels much faster.



Before when the turbo was spooling, the truck would smoke, but really did not seem to make much HP, but now when it smokes it seems to be the good smoke - The overfueling kind , not the bad atomization kind...



As well know I when I used to floor it, the truck would have an initial surge of power, then back off, then back on again and alot. Not the "back off" part seems to be gone. I can only think this was the rail going low, then recovering, etc. Obviously know that does seem to happen.



I wish I would have better documented the rail PSI with the stock CP3 - because I am going by the dealership tomorrow to take some measurements to see what this Cp3 is doing at cruise, mid and hammer down...
