    Catch can question

    I really like the build quality of Mishimoto products. I was looking at their dual can catch system for my 2016 3.5. It appears it does not collect under boost like the upr products. Any thoughts?

    The PCV system on the passenger side closes up in boost due to a check valve. PCV catch cans retain the check valve so you don’t have a very large boost leak. UPR, I think, has a unique catch can for the PCV side that has an extra check valve that can still vent crankcase pressure when the check valve in the PCV line to the manifold is closed.
    The CCV system will function normally at vacuum and boost, with and without a catch can.

    The UPR dual valve catch can setup collects under boost and vacuum into the same can.
    When using separate catch cans for each side, one can will collect while in vacuum (pass side), and one can for under boost (driver side). The driver side also acts as a fresh air inlet for the engine while under vacuum.
    13 SuperCrew Ruby Red 302A, 4x4 6.5 box, 3.31, Roush 22's. Twin catch cans, "leveled" with Bilsteins (-2 front, -3 rear), AirLift, SCT. Other's may have displacement on demand... I have an endless supply of torque at my right foot's demand.
