Snake oil?
This part has been on the market for a few years. Nothing but crickets and can't find anyone that has ever tried them. A few threads debating whether or not it would work but that's it. I figure that it's worth discussing since it is a 7.3 "upgrade??" that has no real reviews.

I noticed that as well, and not a very solid review at that. Figured someone would take a chance on them by now and expose if they are worthless or not.

The logic doesn’t seem to make sense to me. The injectors will use the same volume regardless. I would think reducing available volume in the rail would cause the pressure to fluctuate more during each injection. It would also reduce the overall flow rate.
I agree, the review sounded bogus. More of a sales pitch than a review.

The flow rate is dictated by the injector oil demand and the rest goes over the IPR back to the starting line. I'm definitely voting snake oil.

It's hard for me to comprehend how reducing the volume available to the injectors was worth this effort. Maybe trying to make the HPOP system act like a dual pump setup, but on a smaller scale?

Something to do with decreasing the volume of the chamber nets less of a psi drop in the system to refill said chamber. Resulting in more sustained psi to the injectors. ????

I can see where it would make the HPOP system more responsive to pressure variations.
I'm waiting for someone to come out with a high volume common rail system. Sled pullers would be all over that one.

I would think that would make the IPR and ICP work a lot harder on demanding and supplying oil. I get the basic concept but the fluctuations due to the decreased overall volume to the system would probably cause a decreased lifespan of some components.
