- - Best BOV (https://www.homemadeturbo.com/forced-induction-7/best-bov-1896/)

I put up the topic in the forum to find out how people their BOV so I could decide which one I should get but I'm still not sure. I got a cheap $50 from online performace and it's a piece of crap. It leaks at ilde and at low boost makes a weird farting sounds and at high boost it doesn't sound like it's releasing a lot of air. I found out after trying to be cheap out my project that you do it right the first time and you do it once and save yourself a lot of headaches. So I guess what I'm asking is putting price aside what is the best BOV you can buy. I thought about getting either a tial, HKS SSVQ, Apexi twin chamber, and any others people can suggest. Any input would be a great help. Thanks

it leaks at idle cause theres vacuum, not boost in the line at idle...my turboxs did that too...to get ride of the farting sound, try adjusting it if you can

It leaks because there is shitty seals, and you don't want a vac leak at idle. I have tried to adjust it to get the noise out, it's just a piece of crap.

ok i was just sayin thats what mine did at idle...when you looked at it at idle you could see it was being sucked open by vacuum and if you revved it just barely, it would shut

the bov piston is in the closed position, the are holes surrounding the piston where the air gets released out of, is where the leak is. If you put your hand up to one of the holes it will suck you hand to it. I thought about getting a HKS because they will not leak at idle.

Just get a dsm valve.. the tial and hks valves are over rated.

dude almost all bov stay open at idle cause there vacum going to it so the valve will be open abit this will not cause a vacum leak since the bov is mounted on the charge pipes not the manifold.
I say spend big $$$$ on the hks one so you can feel cool :P

It almost has to stay open at idle. If it wasn't open at idle, when your @ max vac, which is the principle it works on, when would you want it open?

Obviously, if it's NOT open @ idle there is a problem. After all, when you let off the gas (like at idle) thats when you want it to open... to vent off your boost...

I don't see how you think it should work?

As well as not releasing a lot of pressure at full boost, no matter which way I turn it. I'm not trying to be the coolest kid on the block but I have put a lot of time, money, and hard work into my project and I take pride in it. I just want what will get the job done and work the best. I tried going the cheaper route and got an fmu and a fuel pump, as well as a cheap bov and my car isn't runnning that good. So now I'm redoing a lot of things and I just want to get the best. I don't undersstand why you can just answer the question instead of being a smart ass and talking to me like I don't know anything. That's not what this board is all about.
