i do wonder how much more stress supercharging is adding to this piece ;-)
i have a very large additional oil cooler that really keeps things in check.... however bearing upgrade is clearly essential at some point.
OP link to your bearing upgrade kit?

Comes with ARP rod bolts as well. "The bearings we use in our kits have been treated with a process that not only smoothes the grain structure in the surface of the bearing, but also aids in oil retention, providing more lubricity in this critical area of the S54 engine." I like it because the metal is treated not coated. The main issue is the high temp/ high rpm track use but I'm sure the extra load from a blower sure isn't helping
