Any one interested in the oiling mods I did?
So chamfering the galley & passages is moot?
Yep. When my dads engineering buddy stopped by to look at the oiling system and my injection plumbing I told him about what Jim had said.
And Larry said that the size of the passages feeding the mains and rods was bigger that the leak they need to be by some factor I no longer remember.
The upshot was when you are feeding a .0032 bearing clearance with a .287ish passage under even 60 PSI the plumbing was about a bottom priority.
Larry also emphasized keeping the pressure up, not lowering it, because I was considering it. His answer for that was the oil timing is so far off that lowering the pressure will reduce the ability of the oil to get out to the bearing under the load the cavity is seeing.
Most of it was over my head, but when I went back to the dyno with the system set up so I could adjust the pressure externally, everyone was baffled when 100 psi made more power than 80. Some of that was valve train related for sure. But the bearings never looked better after 30 pulls on the dyno with that high pressure. And that was with the W5 heads and we were pulling to 8800 that day.
