Recommend the best BOV for my boost levels.
Like many, my eBay Blow off valve is not cutting it anymore.
It is the ultra-simple recirculating style, and it really doesn't work horribly considering I got it for free, but I get a little compressor surge still and (more importantly) it's not sealing well until about 4psi, meaning I get epic turbo lag at times. Funny thing is It seems to seal pretty well at idle.
I'm fine with spending some "real money" to get a "real" BOV - but want to make sure I get the right one, as I know many are made for pretty high amounts of boost. I'm only running around 8-10psi, and will probably never go to 12psi as I'm trying to take it easy on my daily driver.
Sealing at idle, no compressor surge, and no closing lag are a must. Make your recommendation!

My only suggestion is that you purchase whatever BOV you wish for youor ride from an authorized dealer as nowadays most BOVs you find on EGay are fine replicas of the real thing.
Do your research on this when you buy a TIAL, GREDDY or. HKS. The Tial BOV replica is extremely identical to the original side by side. Read below link

Dual port seems pretty cool, sounds great, and is $163 (cheapest I found so far) which is really not bad at all.
18psi: I will have to take pics of it, I've actually never been able to find this one for sale. I think its a relatively old piece, more when the chinese first started figuring out how to make super-simple BOV's.

Depending on your flange setup you may be limited. Or is it connected via hose?
I recently picked up a red limited edition greddy fv bov, much wooooosh. Actually sounds like a compressor release. Overall I'm very happy with my purchase, solved my leaky bov issue, crap idle, and no more compressor surge (egay greddy rs copy)
the FV also seals at idle due to the new spring design, lovin it.
If I were to recirc I'd pick up a GFB bov, their site has a great selection that may work for your application. They also have vent to atmo bov as well.

Holy **** the FV is expensive, but looks like a great design.
I'm connected via hose but thankfully the BOV section of my intercooler piping is a separate piece connected by couplers, so not a big deal to change it.
Yeah, it seems like a nice BOV solves half the issues everyone ever complains about. Right now I'm really leaning towards the Turbosmart Kompact Dual Port. Good sound, good value, and small size. I will probably pick it up when I get my paycheck this week; I'll report back.

Stop associating bov size with boost levels. Its silly, becuase in our case even something like 15mm would be able to relieve pressure enough to get the job done.
it might be an issue if you drove a supra with a giant snail at 50psi....
....what I'm saying is: doesn't matter. get what fits your hose best

Dual Piston Ram Dump Valve - Unlike single piston or diaphragm diverter valves, this uses counter balanced springs and dual pistons to prevent the valve from leaking air into the intake system at idle. This prevents our diverter valves suffering any of the failures associated with single piston and diaphragm type diverter valves.
