Cp3 Mod

[sangell]

Speeding the pump up is one way to make more power, we are working on making the CP3 pump a larger volume at the current max RPM. More RPM out of the CR motor is just a matter of time. With a CP3 that flows more at stock RPM think what it will do with increased RPM.

I was thinking more long the lines of larger fuel lines from the rail to the injectors (to the rail, bigger rail?). Injectors that are bigger to support the bigger lines. This way we can keep the pressure incheck, closer to stock parms, yet with more volume (bigger plumgers) more fuel can be had at the injectors.



Then again, pressure creating fine atomazation (spelling?) is also a big deal, infact, the biggest deal.



I suppose it's a trade off that needs to be found. So, how can one tell that the fuel line size is to small pressure limits have been reached?

My money is on Industrial Injection. They say they have it figured out, and Brett will be on the 10's in the quarter this year... Noce little bit of banter... LOL

i have been working with brett also, i think their newest plan will work the best, all rpm ranges, no matter what size of injectors, but it might need the mentioned larger fuel lines for flow cause it will have the pressure even at low rpm..... :--)

Yep, if fact I am on the schedule for the first couple of weeks in january, talked to John today. I am very pumped, as I seem to be pulling down pressure quite a bif with my twins program...



tick,tick,tick...

So Tomey... did you get it? Enquiring minds need to know!

It has a reworked fuel solenoid and gear pump,but the power is made by speeding the pump up by around 30%. This was accomplished with a new front cover that relocates the cp3 which allows a smaller pump gear .

RC- Do you pics by any chance and have you measured the rail pressure yet over the entire rpm range with this mod?



Thanks-

by speeding up the pump you will get more flow but its limited flow and will also wear alot faster too, not a reliable way to do it right now. :-laf

 

[RCC]

Whos to say the pump will wear out faster,thats why i am trying to do something noone else has , i figure when your up against the wall on finding more power anything is worth a shot.

you know as well as i do more rpm = more wear, its been tested allready!!. thanks :-laf

RC,

I always wondered how Chris at Relentless had you guys going so fast. I guess he had a secret. Keep up the good work guys!

Well, I do know that more rpm = more wear, i also know that probably anything that is high performance and discussed in this forum creates more wear on some part of the truck. To date the mod has caused zero problems and it is also the first cp3 mod that has an advertised gain that is backed up with multiple dyno runs.

cool, good job. !

can you post the dyno #s thanks

 

[RCC]

Dyno sheets i have , a scanner i do not. I will see if i can get Relentless Diesel to email me one so i can post it here. Then after everyone sees it,i will try to download my 12 second passes at the track, so i can get everyones input on what i might be doing wrong.

RC-



Thanks for your replies to all these questions; it's much appreciated!



That being said - another 2 questions...



1) in a response you wrote on the Arctic twins thread today you mentioned about wishing going back to a 95 gph FASS because of the 150 gph cavitation. Do you feel that the 95 gph FASS will keep up to the modded CP3?



2) What's the modded CP3 like without you "getting on it"? Is the throttle response touchy?

 

[RCC]

I am not sure what the 95 will stand up to . I would have to ask someone who knows. As far as the throttle response,i would not say its touchy but there is definitely more there as throttle the truck.

 

[elandon1201]

On another CP3 thread John at Floor It Diesel reccomends the 150GPH FASS with the fuel pressure set to at least 40 PSI to keep the rail pressures above 20,000.
