Hi everyone. I have procrastinated posting a new thread as there is so much information out there on the topic.
However, i can't seem to get an answer on my particular setup.
-I have an AP1 with kraftwerks kit.
-Catch Can is Renegade Motorsports (vents to atmosphere) https://renegademotorsports.com/coll...nt=45091911555
-I also have an AP2 valve cover ill be installing. And so i will be getting a 10an fitting for the threaded pcv port
currently my pcv setup is as oem. routing to the manifold.
front valve cover return is going to the underside of the 90deg elbow right after my kw filter.
If i incorporate my catch can, do i plug up the bung on the KW elbow and also cap the pcv inlet on the intake manifold?
If so, can this lead to any issues with boost in track situations?
Please provide better routing ideas if there are any.
Really appreciate the help
I run HKS supercharger and I only install catch can on front vent, leave the PCV to go to manifold.
I dont vent to atmosphere though, i route it back to intake after catch can.
I personally am not a fan of venting to atmosphere. There is the pollution thing, but mainly not a fan of it smelling like my oil cap is off when I drive I only run a can off the PCV as that is where most of the oil is lost, especially on an AP1 due to it sloshing into the PCV valve on track. But I am NA so the boosted folks will have more input on their usage
Yes, you will cap the intake manifold and the elbow from the kraftwerks kit. Then you will be venting to atmosphere which wont hurt anything, but it will smell bad.
On a side note, has anyone on here tried routing their catch can to the exhaust to try to tackle the smell (inside the cabin) issues? Does anyone see an issue with this?
Was thinking of welding that piece into my test pipe and running a -10an line from my catch can to the test pipe, maybe with an inline check valve just in case? Thoughts?

If any oil vapor is making it past the can you may have a flame thrower Maybe not all the way out the tail pipe but not sure how it may affect the muffler. I mean normally the amount is small, but like in the case when I forgot to empty mine after track days and it started crop dusting at an autox event, hard to say what that would been like if it were dumping straight into the exhaust vs the combustion chamber. I am also not sure of the amount of vacuum that would be pulled routed to the exhaust vs the intake. And since exhaust is actually more a series of pulses, not sure if you end up at times creating back pressure in the can vs pulling fumes out.
..to beat a topic to death. Catch Can SC'd help
