Radium Engineering - Catch Can Kit - Crankcase VTA - 08, 10-15 Mitsubishi EVO X
An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance.
EVO X CATCH CAN KIT DETAILS
Radium Engineering offers several completely independent oil catch can kits for the Evo X that are sold individually or together using the menu above. The first type do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors into the cabin. The Crankcase VTA kit does not recirculate crankcase gasses back through the engine and is intended for race vehicles dealing with a large amount of blow-by gasses.
The 20-0181 Crankcase VTA Catch Can Kit is an open (vent to atmosphere) system used for high flowing, high horsepower applications. The closed system options listed above are adequate for most modified street vehicles. However, some loosely built race engines operate with a large amount of boost pressure and the OEM hoses can become too restrictive for the excessive blow by. This VTA kit replaces the stock hoses and valve cover fitting with -10AN hose (5/8" ID) and allows the gasses to vent through the catch can to the atmosphere. The stock PCV valve is capped and not used (caps provided) in this kit.
This kit is not a direct bolt-on and requires welding. In order to utilize the included -10AN hose, a 2008-2009 Mitsubishi EVO X aluminum valve cover MUST be used. The included -10AN male bung must be welded onto the valve cover at the location of the OEM crankcase vent fitting, as shown below.
The 2010+ valve cover is plastic and cannot be used for this kit. Like the EVO X crankcase systems above, this crankcase VTA kit mounts the catch can behind the LH headlight so there must be room for the included breather filter (shown above). Consider purchasing 20-0300 Alternate Location Mount separately.
