For high-powered engines, Radium Competition Catch Cans (CCC) offer a significantly larger capacity than standard Radium catch cans, available in large (L) and extra large (XL) versions. The XL CCC meets the common 1 quart minimum capacity requirements set by various organizing bodies, including SCCA, NASA, and Formula Drift.

FEATURES

This iteration of the competition catch cans allows for two plumbing configurations: vent to atmosphere (VTA) and vent to engine (VTE).

Vent to Atmosphere (VTA): The competition catch can is pre-configured to vent to atmosphere. The large non-restrictive outlet is over 183% larger than the inner diameter of the 10AN inlets, which slows airflow and allows vapors to fall out of suspension. Contaminants are trapped with a diffuser, permitting oil sludge to return to the catch can, preventing excessive overspray in the engine bay.

Vent to Engine (VTE): This configuration allows purified air to recirculate back into the intake system. By removing the top three screws, the VTA plate can be swapped for the VTE plate and gasket, converting the catch can into a dual inlet/dual outlet system. The top ports (pink) and side ports (yellow) can be used interchangeably, allowing for flexible configurations.

• When the throttle is open, the PCV valve closes, creating a vacuum in the intake pipe.
• The Radium Engineering PCV valve (sold separately) must flow towards the intake manifold (vacuum).
• An OEM PCV valve can only be used if installed on the intake manifold from the factory. If mounted on the breather port (valve cover), a PCV valve must be installed on the CCC.

The PCV valve can be utilized with a VTE catch can to maintain negative pressure in the crankcase.

CONSTRUCTION

The CNC machined aluminum can is designed for easy serviceability, featuring a dual-stage condensing material design in both the inlet and outlet, ensuring no flow restriction. A threaded 4AN ORB port is integrated at the bottom for plumbing a petcock drain valve. The included bracket allows for full 360-degree rotation, and M6x1mm hardware is provided for chassis mounting. All ports are machined with 10AN ORB (7/8"-14) threads. For engines that do not require all ports, use part number 14-0351 to plug any unnecessary port.

NOTES

• The lower half of the body unscrews for easy draining.
• The integrated dipstick unscrews for a quick oil level check.
• Sold without fittings.
• Catch cans are not designed for use with aftermarket crankcase vacuum pumps.
