In theory... This seems like it might have merit.
But, before the 7.3 rolled over to the dark side of the moon the solution being sought was how to move the pressure and volume from the rail into the injector.
I'm just not sure I understand how this is a solution to that, or how this isn't moving that same problem up away from the injector and into the rail.

I still chat with Charles on occasion. Its been a while I should give him a shout....
I'm not sure that Dave (Golfer) is in it at all anymore since he no longer owns Swamps Diesel.
I have no idea what Joey or Gary are doing these days.

Did Charles' truck run in the 6s?
Not that I am aware his was a street truck. I'm curious for some data. But if it goes like most tests on aftermarket parts there will be tons of variables and no real follow thru or real world testing. Also for most owners not wanting to pull a cab or the engine a upgraded hpop is obviously still much easier to install. This products claims basically go against common logic but and until wowed with information that will likely never surface its all smoke and mirrors. You can easily fudge data in effort to make a profit.

That just clicked for me too.
From their site.
For some reason I was under the impression that this was replacing the oil rail in the heads... Couldn't get my mind around how, or how that would help.
I'm a lot less skeptical now. Might even have to see if this will help a tired old ADR make it a few more years.

Oh wow. I didnt know dave sold swamps!
Hey! You're still alive too!!
Yep. Its a plug of sorts.

I wonder how FFD came up with this specific size/area of the log. Bigger log the better? Lol
If the original volume of the head log(less FFD log) is X, Id be curious of what the volume of the new head log would be with the FFD log installed. Does it decrease it by 50%?

I think she is about $100 short right now.

Since my request has been fulfilled - I shall oblige. Thank you - Tamisha was ecstatic.
This whole debate can be boiled quite succinctly down into two issues:
1) Does this thing actually improve performance? Cass said he has evidence to support that it does with improvement in several test trucks as well as years of experience with these trucks. I'm inclined to give him the benefit of the doubt - its no secret that we've known each other for years and consider each other friends. I eagerly await the presentation of said evidence with the rest of you.
2) How does it work? I don't have a a concrete answer on that - but I do have theories which I will outline in a moment. First I'll post a paraphrase of what I told Cass "I know for a fact its not that bull**** you posted on the FB ad" ..... Maybe that isn't actually paraphrasing.... LOL
Theory 1: Firstly - we need to dispel a myth that I have seen repeated in this thread numerous times. Engine oil is compressible. That is a FACT. This is especially true when it comes to aerated oil which is pretty much the only thing that exists in a 7.3L Powerstroke. These rails take up a known volume of the factory "reservoir" giving less volume to be compressed. This could be a method of stabilizing the pressure.
Theory 2: This would be my front runner theory, but its more of an educated guess. These inserts actually dampen the pressure waves that are taking place within the oil rail. Fluid harmonics in a transient flow like this are a PITA. By inserting this device into the oil rail its giving a new surface for the pressure waves mostly being generated by the starting and stopping of oil flow at each individual injector a new surface to bounce off of and dissipate.
Theory 3: I don't have one.... but that doesn't mean there isn't yet another undiscovered mode where this device could improve the rails. If you have theory where this might work - please share.
In any case - if the tech performs as advertised regardless of the the actual physics behind the why it works - that might be what truly matters. While the fluid mechanics of the initial theory that lead FFD down the path to develop this might be fundamentally flawed, it is quite possible that they have stumbled onto something unique and quite worthy of the small price they are asking (compared to anything else for these engines). I think we often forget that sometimes some great things are discovered entirely by accident. Corn Flakes, Teflon, Post-It Notes (the adhesive), silly putty, etc.... were all things created in the pursuit of something else.
That is my take on this. Does it work? Maybe. How does it work? Not as its advertised currently.
