Radium: VTA to VTE Competition Catch Can Adapter
This VTA to VTE adapter can be used to convert the previous generation of VTA Competition Catch Cans to a dual inlet and dual outlet VTE Competition Catch Can identical to the current offering of Competition Catch Cans.
This system permits the purified air to recirculate back into the intake system. By simply removing the top 3 screws, the VTA plate can be swapped for the VTE plate and gasket. Very quickly, 2 additional 7/8"-14 (10AN ORB) ports are added to the catch can converting it to a dual inlet/dual outlet catch can.
When using this VTE setup, the top ports (pink) and the side ports (yellow) can be used interchangeably, i.e. top ports are inlets and side ports are outlets or side ports are inlets and top ports are outlets. Do not mix the top and sides, both inlets should either be on the side or the top, and both outlets should either be on the side or top.
When the throttle is open, the PCV valve closes and there is vacuum in the intake pipe.
The Radium Engineering PCV valve (sold separately) flow direction must be towards the intake manifold (vacuum).
An OEM PCV valve can ONLY be used if it is installed on the intake manifold from factory. If it is mounted on the breather port (valve cover), a PCV valve must be installed on the CCC.
A PCV valve can be used with a VTE catch can to keep negative pressure in the crankcase at all times. The diagrams below illustrate airflow based on throttle positions/load.
