To do a VTA catch can or a sealed one on a 800+whp Evo?

Hey guys.
My curent catch can setup is 2 12am lines of the valve cover to a baffled VTA catch can. I have the option of getting a new catch can built and can't make up my mind to do a sealed one and have it get sucked out by exhuast or vent it to atmosphere? Car currently makes 771 awhp on 35 psi and plans to turn it up past 40. It's a 2.4 with a 6765 and all supporting mods to make 900+.
Thanks

I've ran both. I prefer a sealed one for daily driving. I've since going to a VTA with 2 -10 lines. It works fine but you can really smell it when you start driving the car hard. That's my experience with it anyway.

This is how it is now.
It is being switched to a Forward Facing Setup once i get the new manifold with a full exhaust out the back.
i have smelled it a few times when the wind was blowing just the right direction and i had the windows open and it was not a pleasant smell.

Ya my set up is very similar. Unfortunately I didn't realize there was a smell until I had totally redone my catch can set up. Ah well, I'll deal with it for now.

Need help for rear valve cover catch can setup using 10 AN fitting

Would you mind chiming in on a recommendation?
Im shopping for a dual catch can kit setup
as far as the front intake side of the valve cover I have a 6 AN fitting and will run that line to one port of the catch can and run the second line from the catch can to the intake...

for the rear of the valve cover I have a 10 an fitting... How should this be done I know the first line of course runs from the valve cover to the catch can but for the secondary port what should I do? block off the intake manifold port? and dump the secondary line to the ground or is there another option? on speaking for the rear valve cover
