Is there any need for a catch can for use with the s/c?

 

Yes, very good Idea. I recently got around to installing mine.

 

The way it's set-up stock I notice that the boosted air goes through the breather on the intake manifold pressurizes the head and blows oil through the other Pre-throttle body side breather.

 

Rather crude drawing, but I think you can see what Im explaining.



The Charged air that is going through the breather into the head, pressurizing the head, also blows by oil into the other exiting breather tube.

 

interesting - did you do the homework in which one to get at the best cost?

 

Also on the pressurizing the bottom end, you do loose a small amount of boost when this happens & the pressure in the case is horrible on the seals / bad overall. Was a nasty oversight by TRD. I noted this last year somtime in the sc post I made.

 

^ please explain a bit more - i missed that post

 

For the S/C, I installed a Dual baffled catch can:

For the pressurization issue and reduce blowby I used Krank Vents to increase vacuum:

I just picked up a cheap one for now, from my buddies car shop 222 Motorsports. But later I want to get a better set-up. It works for now though, with the previous stock set-up I was losing oil like crazy due to blow-by... about a quart every couple weeks. Oil level stays constant now with the catch-can, no loss between changes.

 

This is the set-up I'm interested in. Are there pre-existing holes that you attatch the catch-can to under the battery?

 

^ read it - it shows you that you use one of the holes from the battery plate

 

where did u buy those cans and pcv valves, do u have any pn for the pcv's?

 

the can is from Saikou Michi and the krank vents i ordered from Automotive Speed. Links to both of their shops are in the articles.

 

woo baby - its a few bucks for those few things. I was thinking they were around $80 - good deal though .... I might be down for it .... its too bad there is such a minimal amount of room to work

 

man, those are pricey, so did u notice a difference on the butt dyno by chance?

 

Anybody else with a Catch-Can, what did you guys use to plug the Intake Manifold bung?
