I'm reading the exact opposite of what you posted here about blaming FCA. I'm reading IHI is to blame for the bearing issues and not FCA.
I also read on the Hellcat forum, after a forum member did some "research" on the history of IHI superchargers, that they were not that great at all.
His facts across the board are skewed a bit. Just assumptions from reading is my "assumption".
Gen III Vipers doesn't have bearing issues. In fact it's a pretty stout engine, same for the Gen IV. The Gen V engines do have bearing failures but it's not due to cost cutting of the bearings used. Easy to post blame there though. It's mainly due to casting problems with the block as well as oil supply issues. This is how rumors get started though.
Good info on the recalls referenced above - https://driveviper.com/forums/threads/12394-Gen-V-2013-2015-oil-consumption-RECALLS-R28-amp-R29
I don't post blame on FCA at all. I put it on IHI as FCA wouldn't tell them what bearings to use. FCA would push them on cost and IHI would make the call on where cost could be cut to win the bid. If the cost is really $13K for a new blower I would be embarrassed to put sub par anything in it as the MFG of the part.
