Description
The Radium Engineering Competition Catch Can – Large (20-1772) is engineered for high-performance engines that require superior crankcase ventilation and effective oil vapor separation. Designed for high-horsepower street cars, boosted applications, and track vehicles, this catch can offers significantly increased capacity over standard units to better manage blow-by and crankcase pressure under aggressive driving conditions.
This universal catch can can be configured for either Vent to Atmosphere (VTA) or Vent to Engine (VTE) operation, making it adaptable for a wide variety of custom PCV and crankcase ventilation systems.
Manufactured from CNC-machined billet aluminum with a durable anodized finish, the Competition Catch Can features a fully serviceable modular design and an advanced dual-stage vapor separation system to maximize oil control while maintaining unrestricted airflow.
Features:
Dual Configuration Design
- Pre-configured for Vent to Atmosphere (VTA) use
- Easily converts to Vent to Engine (VTE) setup
- Flexible installation for custom performance applications
High-Capacity Performance
- Larger internal volume for high-output engines
- Helps reduce crankcase pressure and oil contamination
- Ideal for turbocharged and supercharged setups
Advanced Vapor Separation
- Dual-stage condensing system improves oil separation efficiency
- Internal diffuser slows airflow and traps contaminants
- Reduces overspray and oil mist buildup
Maximum Flow Design
- Outlet is 183% larger than 10AN inlet diameter
- Free-flowing chambers minimize restriction
