This was attached to my stock side mount, i'm guess the smaller tube is a vacuum line(goes to the throttle body or something?)...Can i disconnect the rubber connector and large piping, would this be safe and basically atmospheric bov venting?

there is a trick to make the stock BOVS to turn them into a pull type. you know so they wont leek and stall your car out when idling. i just saw a thead about it not to long ago.

well heres what i did, would 17x9 +15's with 235/40/17's clear the bov(i'll have a better idea after i install the stock wheels, cant really imagine them on there this being my 1st s13 that i've barely worked on?) i'm not gonna install those for a while.

There's the pull type modification thread.

see I thought the stock BOV would leak if it was run atmospheric. I have a stock EVO VIII Bov on my SR recirculated, and I would love to figure out a way to make it atmospheric

dont forget to tuck your harass higher or relocate it inside the engine bay. you dont want to burn through it with your tires.

thats a pretty nifty idea. It would be easy with the stock BOV. All you need to do is make the inlet the outlet and the outlet the inline. Hook up the vac line as you normally would.

I wonder if the vacuum from the intake will be strong enough to pull against boost. Also I wonder where you would start running into compressor surge problems with vacuum strength vs. boost pressure
like yes this works, but only up to say 15psi or something. I'm going to try with my Evo VIII one as soon as I get off work

Thats my thread.
I boost all day at 24lbs. no compressor surge and it blows as soon as I lift no matter what the boost level.
You have to plug the port like I stated in the thread. it needs to change the reference to the correct side of the piston so you get proper pressure on the diaphram.

its fine for any level of boost. you can recirc it or run atmospherical. I run blow through maf so venting to atmosphere works great with this setup.
Its also loud and has a nice whooooshhh sound.

They've proven well on the HKS SSQV. Pull type FTW. They are hte most responsive. If your worried about compressor surge, dont look anywhere else other than a pull type. All traditional push type piston BOVs have initial surge before it vents. Every single one of them. Pull types do as well but you can hear its way less than any push type piston BOV.
