Oil Separator
#11
I'm sure you're right, you don't actually HAVE to have a separator when NA, but these engines seem to have quite a bit of oil in the PCV stream. Getting this oil, or most of it, out of the air being put into the intake manifold has to be beneficial. I wonder if that isn't where a good bit of the carbon that cements the plugs into the heads comes from. I know a lot of Mustang owners (myself included) complain about occasional clouds of blue smoke on start up. Oil separators reportadley get rid of this too. I've seem pics of the butterfly plates in the heads with baked-on carbon that can only come from this oil. To me, it's a $100 improvment that I think can only help my engine. It is easy to install, looks good and from what I read, it works. Just my $.02.
I guess if it gives you peace of mind, then go for it. I was just curious, as I have seen very few used in high horsepower setups, and I, personally, have never used one in any build.

S197s create a fairly significant amount of blowby. When I installed my whipple, I pulled the stock upper intake off and oil dripped out of the runners. When I removed the throttle body, I found that the blades were soaked in oil. With almost 11psi, I get a couple of tablespoons in the catch can every 1,000 miles.

I pulled off my throttle body the other day, i'm N/A too, and had oil all over the back side it. I wiped around the inside of the intake manifold too and had some nast oily residue all over the rag. It was tan just like the oil I just put in it. Mobil 1 5w20 ofcourse.

When I saw the crap those two hoses dump into my intake that did it for me. I just bought the Steeda kit because it is see through and is pretty small. At the moment both sides of my 05GT are vented into the atmosphrere through valve cover breathers. I'll install the kit this weekend.

I agree totaly. When I saw the garbage in my intake that was it for me, I vent mine through filters too. Tree huggers can go ... well you know.
