Coolest Oil Catch Can

Ill

G37sHKS,
I actually was PMing Sh0vel about this a few days ago since I am looking to run one in my GTM TT when I get it all installed. This is what he said in his reply;

So, for an FI setup, you would want to plumb it a little differently. Basically, put a breather filter on the fat connection (back of the cover) and put the front connection into the catch can with the can outlet dumped into another breather filter.
Then cap/plug the manifold nipple (sticks out the front of the manifold).
This is the only way I see to do it that will relieve pressure build up from blow-by and still catch the oil. Crankcase scavenging at non-boost times will be a little poor, but most agree it's not a big deal. This is the really simple way of doing it.


Now the more complicated way;
For my own car, I would probably set up a pair of check valves on the cans.
Basically one between the manifold and the can that only allows air to pass IN TO the manifold, not out of. Another between the can and it's breather that allows air OUT but not IN. Then I'd plumb the fat connection (back of the cover) to the inlet pipe after the MAF (if a connection is available there).This way, you maintain the excellent scavenging off boost but won't have issues while on boost.

I replied and am patiently waiting for him to finish a diagram / parts list he's working on, he mentioned it earlier in this thread.

<slightly off topic> I ordered my Saikou Michi catch cans today </off topic>
