Right now I have two saikou michi cans, each has a drain that I have to manually operate. Both have one input and one output. The first can handles PCV evacuation back to intake manifold. The second can handles VC output by Dizzy and outputs to the intake pipe. The crank case port goes to the VC (I have a 20v VC). The system stays sealed, both cans are filtered. The PCV side has a one way valve to block boost pressure from getting to the crank case.
What I don't like about these saiku michi cans, the barb fittings are huge and force the can to take up too much space. They are very tall due to the top port and drain port. My favorite is the Radium Engineering setup:
Universal Dual Catch Can Kit They are the best of the best. However, I don't feel the need for threaded ports/dip stick/CNC Billet and so on. All those are nice, but add to cost. $300 was a lot higher than the $160 I spent on my two sans. I think something right in the middle around 225 that filters, has a compact size and proper port count would be awesome.
