Pictures you say?
From the thread mentioned above, the DME map of oil pressure vs. RPM and load.
From that i developed this:
A spreadsheet with all the values from the two charts above so that i can generate graphs including n55, s55 and my n55 boosted pressure values.
Here is the first plot using 85% of pressure for an 18% boost in pressure.
The two sets are baseline N55 motor at the bottom three and boosted address the top three.
Here shows the N55 curves (at 15, 30, 100% load) (orange), my boosted by 25% (green) and stock S55 motor (pink)
It's higher than needed but you can see how it's nearly identical in the lower RPM range and almost a perfect compromise between n55 and s55 in the oak power band.
Once i can confirm the values that work i will share the BOM and the process so anybody that has an N55 but would like to not play German Roulette every time they punch the throttle, can copy me and possibly double the lifespan of their motor while using a reasonable oil change interval like 8000 not 5000 miles.
I'll be pulling the bearings from the 92k motor I'm about to install in my wife's car to get a sense of how worn they are. I'm confident they will be more worn than they should be especially with start stop.
The parts to do the prototype install and diagnostic come in a few days and I'm planning to get it installed next week.
More to come!
