CB flanged crank bearing modification

[Alexander_Monday]

I have ordered a CB flanged crank and the type 1 to type 4 bearings.
This is for my supercharged street warrior (not an every day driver).
Considering the bad wear reputation of flanged thrust bearings I wonder if an old V8 trick would help.
Instead of me trying to describe it, this video does a good job.
If not help, would it hurt to try it?
Thoughts?

Not a bad idea, am curious as to surface finish on the crank thrust surfaces, harder to inspect in the gap.

Not a bad idea, am curious as to surface finish on the crank thrust surfaces, harder to inspect in the gap.

I will try to remember to report what the crank thrust surfaces are like visually and feel.
I do not have the instrumentation to do an actual roughness test.

I asked Mark at CB about the bearing modification and he knew about the idea but didn't mention anyone doing it on a VW.
He didn't think it would hurt anything to do it so I am going to do it.
I will see what the CB aluminum case has for a drain back and use my judgement to enlarge it or not.
Because I want to give this engine every chance to survive as a weekend street warrior, I am also getting an RLR street 6 clutch to reduce the pressure on the thrust bearing.
Hopefully it will have smooth engagement, there are conflicting reports on engagement (on/off or smooth) that I have found on the web.
The pressure plate I was using (a local company made) with a 4 puck copper or a 6 puck black magic was close to on/off.
But it was slipping when shifting at WOT @ 14# boost with the 2110 so an upgrade was necessary for the 2387.
I do know and always have started any manual car in neutral without holding the clutch down so the oil can get flowing.
I am going to try the Moroso Accusump again, I used to use one to prelube before starting.
The first one started leaking after probably 12K miles and 10 years.
I replaced the o rings and polished the inside but it started again.
I bought a new one that started leaking shortly after installing it, so I removed it and haven't torn it down yet.

Seems like a small electric pump for prelube (with a check valve) would be smaller, more reliable and a lot cheaper, and probably last forever. Won't help if you run out going around corners but I suspect you are mostly going straight.
