I will take these from you, if they are still available. As a new user I can't PM you. I can offer $100 + I pay for shipping with a pre-paid label. Please PM me or email rohan.verma21@gmail.com and I can send payment.

Thanks

A bit ricey but I like it.
One hks bov ( took a bit of custom work to make it fit, the c clip needed to be grinded a bit to fit.)
One greddy bov

The sound is a bit exaggerated since its in a tunnel, with windows up, you barley hear it. Windows down and flooring it, sounds like video.

Looking good cousin!. BOV is really not an item i would spend money either so good choice lol

[dragazn]

Is it me or the mount adapter just went up again, its at $45, now.

Yeah looks like the eBay ones have gone up from $19.99 to $39.99 to $45 now as far as the Greddy type adapters. The company is AWD Motorsports actually locally to me I guess as the popularity has gone up on them they have been raising the price. You can get it from the original source I got it at from:

Greddy - http://www.atpturbo.com/mm5/merchant...Category_Code=

Tial - http://www.atpturbo.com/mm5/merchant...Category_Code=

HKS - http://www.atpturbo.com/mm5/merchant...Category_Code=

Where did you get the HKS, seems like by reading multiple pages, people are having hard time on the HKS, they have to modified the C clips a bit to get it to fit, or did you have the same problem?

Yeah, it's quite annoying. I emailed AWD Motorsports to see if I could buy directly at the $19 price and didn't get a response. Perhaps that was another signal to them of the demand

[cale39]

Looks like there are still a few left at $39 each, but they are the Tial and HKS-style mounts.

These will work for this DIY, right? Or are they the ones that are not exactly fitting into the stock charge pipe and we should look for a Greddy style (the ones that are now $45)

Update Cheaper Adapters: Thanks to Ridehard335



$19.99

------------------------------------

1. I bought these adapters ($39 each) they have Greddy, TIAL, and HKS BOV type adapters for stock chargepipes. These are specifically made for our 335i N54 Charpepipes so they lock and fit just like stock diverter valves.

Greddy - http://www.atpturbo.com/mm5/merchant...Category_Code=

Tial - http://www.atpturbo.com/mm5/merchant...Category_Code=

HKS - http://www.atpturbo.com/mm5/merchant...Category_Code=



I bought the Greddy type adapters like the image above.

-------------------------------------
Update:

Updated the BOV these seem to be better the original ones I used worked great when I first put them in but after taking them off and putting them back started getting a little squeal(almost like a brake squeal) after the wooshes. Swapped them out for these never had an issue and they have been taken off and back and off again no issues. I left them at the spring rate they came with but you can adjust them with the screw on top of them.
--------------------------------------

2. I bought some $30 Greddy Type BOVs from eBay specifically these:

eBay BOVs

Honestly very surprised on the quality of the build of these BOVs they dont feel cheap whatsoever pretty heavy as well.





3. Once I received both sets of items I put them together very straight forward.

4. Remove the stock diverter valves and plug the intake holes. What I used is the rubber caps that are put on the bottom of chair legs 7/8 size the 1' should work as well. I got a set of 4 at Lowes. They are pretty tight put I also bought small clamps from pep boys. Here is what it looks like.



5. Its almost too easy but just slide the BOV with the adapter attached into stock chargepipe and lock in place, you can position the BOV in 4 ways I decided to point them down. Connect the two hoses from the back of the BOVs to the stock hose originally connected to the stock diverter valves and your good to go. Here is the final pic of the setup:

This is a pic to show where they slide into you dont have to remove charpepipe or anything like that.





So things you will notice you will have two woosh sounds one right after the other which at first it was different but I actually like it now.

Question that might come up does it sound too ricey you got two BOV for crying out loud?

- Actually just cruising unless you have the windows down and radio off you wont really notice them. Its not an annoying sound that will make you feel like your driving a ricer.

- However when you are stepping on it and let go of throttle you will notice it and thats all I was going for you can adjust the BOVs sensitivity with screws and nut on top of them. I actually had to loosen the rate some.

Any noticeable performance gain or loss any limp mode or boost leaks?

Car runs as strong as always obviously this will not improve performance at least not any noticeable difference. I took the car to the track at FixxFest ran 13.1 which is what I expected in 90 degree weather and after 3 hour drive (JB4 Map 5, BMW DCI, Muffler Delete). No limp mode or boost leak that I can tell and bcz car is running as before that's what I'm basing on the no boost leak.

This is a cheap mod if you drive a BMW you should buy a $600 BOV if not go buy a Honda?!?

I say to each his own if you don't like it and want to criticize it go right ahead wont bother me none. You buy what you want to buy for your car, I buy what I want I'll drop some money on somethings but not BOVs personal preference.

Will this bov work with the hks adapter?? http://www.ebay.com/itm/Universal-HK...sories&vxp=mtr

[Tucker020]

Got mine all installed today......try and post a video later. Sounds great tho

[Hecticrulerz]

Can some one tell me the size of the adapter ?

SAME PROBLEM, i modified it.

[Tucker020]

One page 3 of this thread I posted an ebay link to some Diverter Valve plugs; they do not fit. I edited my original post as well. Here is the link to the plugs I am refering to:

http://www.ebay.com/itm/Billet-Alumi...dc4cc2&vxp=mtr

I instead used the same 1" rubber chair caps that the OP used. They fit perfectly. Got them at Home Depot for $4.

[Tucker020]

Anybody that installed the Greddy BOV's need to adjust the screw any? According too the Greddy instruction manual, it comes already in the softest position. Wondering if anyone made it "Harder"

I also have that question, If someone who has the greddy type BOV working well please post a measurement of how far the threaded needle is from the top of the screw to the top of the threaded needle.

Currently mine is a few turns softer than stock.. but i dont want to run somthing that may be too soft and damage anything.

According to the Greddy Instruction manual: "The adjustment is preset to the softest position from factory. Do not turn it further out than this position." So, you may wanna turn it back...but I don't know?

[SPGspeed]

Great now i have no idea what the "stock" position is... anyone else who is currently running this set up have a length or amount of turns in or out stock is?

[Tucker020]

From the top of the nut, to the top of the threaded needle on mine are....one is at 7/16" and one is at 1/2 ". So I'd say 1/2" is probably stock

Thanks

Thanks,

I wonder if it is ok to soften it more, I don't get a good splash sound unless i really hammer the throttle.

Here's a good write up I found concerning the BOV setup.
