AOS/Catch Can Needed for Supercharger Support Mod? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I know this is one of the most debated questions in the 86 community.
I ask this question because CSG Mike brings up the point of an AOS/Catch Can not being necessary due to the differing design of FA20 vs the traditional boxer motors boxer-heads like to focus on (mainly the EJ). So what do the other 86 owners think? I'd like to hear from everyone who has a strong opinion!

my PCV side catch can collects a lot of oil and i m not the only one who noticed it

the crank side is almost irrelevant, but a catch can on the pcv side isn t toally useless
not mandatory though

So even a single catch can on the PCV side should be plenty? Or would you recommend the dual Radium setup?

i have the dual radium

crank side doesn't catch a thing

I'm even tempted to sell it for money and keep just the pcv side
