That bov blows off into the atmosphere and therefore your car will barely idle or either not idle at all, The Racing bypass valve is what you might look into thats what i got and i love the sound its pretty loud.

I as well have the Racing bypass valve and love it. Sounds better than the 2g bov by far. Also dont have to worry about venting back to the atmosphere.

I used to have the H-BOV on my car. No idle problems at all, once you slap 6 of the adjustment washers into the piston chamber. I would get the H-RFL though. It uses the same spring, so you would still want to use 6 adjustment washers, but it looks nicer and is a bit louder too.

And yes, use the search function.. I have done a review of this valve before. Along with all of the other TurboXS BOV's.

I have the TurboXS Type H-34 RBV. It can be vented to atmosphere OR back into the intake; like mine is.
So far I like this valve alot. If you get it, you need their adapter kit.
The washers they provide give it decent adjustability too. Each washer changes the vacuum release point, I went through it and tested each washer for the vacuum increase point and set it close to where the stock cbv would open. Then I ended up taking some washers out and only leaving two washers in it.
It's kinda big, but I was easily able to set it up where I could hook up a recirc tube back to the intake.
All in all, a very nice piece so far!

Help me :(

I got TurboXS H34 bov from trader and i have no instructions... Can someone tell me what is the purpose of those washers and where do they fit in?? Do they fit in the opening that vent back to airbox or the other opening that connects to the upper intercooler pipe? Also, how many washer did u use? and did u vent back to airbox or to atmosphere?

Sorry for long questions.. Any help will be appreciated..

Thanks.

First you gotta undo the little allen screw, then twist the top off. Just be careful because theres a huge spring inside and it will pop out rather fiercly.
When you have the top off, take out the spring and put some washers inside, then put the spring back and twist the top back on. And thats about it, i had 4 washers in mine.
You might need more or less, depends on the car.

So the overall purpose is to put more pressure to the spring or make the spring become more tension...

Did you ever try to vent it to atmosphere?

Thanks again for the help.
Sounds like you have the RBV. I wouldn't vent it to the atmosphere, although you can. The spring it comes with is MUCH softer than the spring in the RFL and H-BOV which are designed to vent to atmosphere.

If you have any TurboXS questions, feel free to drop me an email. I do DSM tech support for them.

Newbie questions:
I just wonder if that will allow me tovent out to atmosphere??
How can you tell if you have put enough washers in it?

Thanks again for the help!
Yes, it can vent to atmosphere.

You do not have enough washers in if:

The valve is fluttering open at idle. Look into the exhaust port of the RBV while the car is idling. You can see if it is opening or not.

You have too many washers if:

You experience any compressor surge while driving. Compressor surge is a fluttering noise. You know what the valve is supposed to sound like, so listen and see if it ever sounds different. The noise is extremely different and should be very obvious.

You want to use as many washers as possible, without getting compressor surge.

I think I've put too many washers in mine. Thanks for the info ProjectGSX :)
