A question for Diesel Power...

[AEzzo]

your statments have been answered, this is what we have come up with to supply enough fuel for the modded cp3, what we do to mod the fass is proprietary. think about it you need for the stage 1 enough flow for at least 7-800hp. that figure you posted is not close because your not factoring in long duration events and high pressure. 600hp looks good on paper but how does it get to that power level, at that level you are running the rail dry, it starts about at 500hp w/ duration and pressure boxes, belive me there is more to it than this, while i could right a 10 page report on this and relating matters---i wont. this is not a sales pitch, if you dont belive what we (the people modding the pump) say you should do in order for things to properly opperate, than why even worry about the cp3. sorry but i really dont have any data that i can release on the modded pumps yet

Fair enough, I'll just sit on the sidelines and see how everyone else does.

I am trying to understand. But all I've heard from you is a sales pitch. Without flow data everything you say is all but meaningless. I would think you would be able to tell us what exactly is needed in the way of flow. How can you not know exactly what the FASS flows at 40 PSI. I would tend to think the 150 is rated at free flow and would drop off at higher pressure. I'm not trying to start an argument, but trying to learn and make the best decision possible before laying down my hard earned money. To do this I need facts and not a sales pitch. :-laf



Trying to figure out the BSFC of a 600 HP Cummins and I come up with about 70 GPH. Now I added about 30% to figure in cooling flow. I could be wrong but this sounds a little more reasonable.

i am trying to find a way to help you better understand, the cp3 is delivering alot of fuel=which means it needs alot of fuel to feed it. also the stock relief valve will also play apart in this for those that dont want to use a rail cap, the more pressure the more the valve will dump more fuel into the tank being at or close to that thresh hold, and dont forget that the valve will weaken and further reduse pressure when the valve is relieved and the cp3 is still trying to keep up with what ever fuel pressure is being demanded of it. it needs that much fuel for those and more reasons. thanks :-laf

I will also wait till numbers become known to the public (all numbers from everthing). Then I will plan out everything else before my money is spent. Just want to hear about different numbers from different setups before I decide what I want. 1234567890=____?rwhp/_____?ft. lb.

Now I don't have a perfect understanding of the relief valve but I was told when it opens it opens all the way and the truck will fall on it's face.



Are you saying that your pump will try to overcompensate for the relief valve being open? When does the valve get a chance to close? If I see what you are saying correctly you are basing your flow on flow through the relief valve also.



Thanks for taking the time to help me figure this out.

I just bought a FASS 150 for this stage 1 cp3. Its still in the box and if the 150 mod is proprietery then do you sell a kit to make 40 psi.

 

[Diesel Power]

yes we will mod the fass pumps,or you can. it doesent take to much to do it. and the relief valve is only part of the equation. !! thanks

AEzzo, thanks for the PM>
