Thoughts on oil pressure vs flow?

[1795]

I am interested in hearing what the engine builders have to say on this topic. There was a discussion recently among several vintage race car drivers about flow vs. oil pressure after somebody (not me) burnt their main bearings. Part of the discussion included a recommendation to go with the oil filter that offered the least amount of resistance to flow, as race engines are rebuilt more often than engines that primarily are used on the road and it is more damaging to them to reduce flow than to let some small particles through.

I would not necessarily equate high pressure with high flow volume. While there may be some overlap, I can easily see a situation where due to tight tolerances oil pressure may be high and flow low secondary to restrictions. At the same time very loose tolerances may result in high flow with low pressure.

My guess would be that many factors come into play.
