...and also post how much boost you're running, and whether the BOV works well for you.

pictures pictures pictures! (If you don't have a picture, go take one or don't post!) :oogle:


Because the OP should always start things off on the right foot, I'll post a picture of one of my older setups. There is currently no BOV on my 242 or I'd post that. I'm actually in the process of choosing my new one, which is why I'm making this thread.


This was on my old 245 Turbo. TurboXS Knockoff. 15 PSI. Seemed to work pretty good, and I was able to adjust with the included shims so that it didn't leak at idle. I never pressurized the intake to check for air leaks, but I'm almost certain it was pretty solid actually.

What turbo are you running and how much boost? What system (LH 2.2, MS, etc)?

04-28-2008, 11:19 PM
TurboXS H34 or something like that. Its the same thing as a RFL except instead of the horn theres a port that you attach the recirculation hose to. I had it run open atmosphere before and LH 2.2 hated it.

I run a Greddy on my 855R and to be honest it sounds whimpy compared to my TurboSmart Stealth series BOV I run on my Newman 745 V6. The Jap BOV's sound all alike. IMHO Nothing sounds like the Australian made Turbosmart BOV's. Very distinctive sound! :cool:

Cheap Ebay TurboXS knock off. really wish I shelled out more money for the real thing. but its not too bad once I fixed it. when I first installed it. it wouldn't blow off even at 15psi. but I took it apart and used some really fine grit sand paper to "debur" the piston. after that its operates pretty nicely getting better everyday with more oil from my breather system getting to it.

In the cold mornings when I blow off it looks like my car is purging NOZ from the front grille. hehe.

Quick questin for you BOV guys. Since the stock diverter valve or whatever it's called it located down low and has that big hose going to it from the intake, what do you guys do with that hose once you run the BOV over on the hard pipe for the intercooler before the intake? Or am I thinking of the wrong part?

Okay so BOVs have been talked about like no tomorrow on LH 2.4, what I don't understand is how they will blow off when going from boost to vacuum, but won't they still blow off and open when you just lift your foot off the throttle but stay in gear?
For example, when Im in 4th and I go to pass someone, I go into boost then I slow down, therefore my CBV opens because my vac goes to like 21in/hg(but its always open in vacuum), but if I don't go into boost and I let off the throttle but stay in gear won't a BOV still open at 22in/hg even though I didn't boost? Thats why Im confused because if its open when I decellerate in gear, the car would for sure stall because its sucking air through the BOV and not the AMM.

And since yours is a stock cbv it's kind of whimpy and slow. Some of the ones I've used would easily open from letting off at 0psi.

Here's my current "bov"!
http://www.cravingboost.com/cars/bov.jpg

Haha, compressor surge sounds awesome. Probably not the best for the longevity of my turbo, so I am planning on putting a BOV on there some day. I ran a stock cartridge 60/63 for a year with no bov and then one day on a road trip it shat itself, though I'm not prepared to fully blame the compressor surge, it was a really old turbo running 10-15psi for 10-20k miles, plus whatever abuse it was put through before I got it.

My John Deere turbo is running 14psi now and barks pretty good when I let off.

But a CBV is open whenever its in vacuum, is it not? Its constantly recirculating until you go to 0 vacuum in which case it will be closed and allow you to boost.

A recirculation valve often stays open a tiny bit yes but a BOV normally will open when you shut the throttle plate from a higher load condition and create a momentary high vacuum condition. After a while the engine will stabilize the vacuum at a lower RPM so the BOV will close again.

Simple answer Sean, Megasquirt :-D. You can run open throttle body and it'll drive just dandy. So a leaking bov or cbv won't matter. I've used the little black plastic Bosch ones that tryingbe posted in his second picture, they work great, but they are open at idle and blow air out, so LH would hate it.

They sound slightly different one way vs the other, but both ways work. LH will hate that thing if it's dumped open, filter or not, since the spring is so soft that it blows out metered air at idle. MS love it ;-).

In my mind, the way pictured is the proper way to install it. I sold all of mine and I don't feel like buying a real BOV, so I've been meaning to head to the junkyard and pick another one up for a long time now.

That is kind of cool, or maybe it's just me, but you could mount it on the cold side pipe facing back to the intake side directly, making it easy to route back.
