Engine experts, Oil pump and pressure Options

[r_towle]

I’m going to build a flat 8.
Not asking to debate this, but it’s the premise of my current research.

In the only successful motor built like this, in Brazil in the 70s or 80s, they had issues getting oil at sufficient pressure to the crank/valves furthest away from the pump.

So, I have two ideas.
If you look at the 911, there is an external oil feed pumping oil into the valve train.
I’m thinking of something like that, but not sure how to route it, or the right place to inject oil ….maybe at the beginning of the second case….or the other end and feed it backwards.

Or
I could enlarge the internal oil galley in the first motor to increase volume.

I expect I will need to find the highest volume pump I can.
I assume different pressure relief valves.
I assume eternal oil cooler and filter.


The rest of the architecture looks fairly straight forward.
I need help, experience, and some hotrod thinking on the oil issue.
