Bov?
 

Okay looking for a new BOV as my cheapo ebay one is sticking despite oiling. Looking for any recommendations.

Don't say the bosch one as I used to run one and I liked it a lot for under 10-12psi, but above that I think it leaks a bit. Need something more stout for 14+. :)

I was thinking about the GFB one that FM used to carry, but I've also read a bunch of reviews that over time it sticks as well.

Thinking HKS SQV, but that one is $$$. Any others?

could always do tried and true 1g dsm, won't matter if you don't recirc since you're a squirter:gay:

I've read good things about them ^. wish I knew more.

For around 8psi would the bosch valve work just fine? its real cheap.

Go tial. Sweet sound if you are looking to vta.

I have had a lot of success with the HKS SSQV.

I used to have the GFB VTA, but it always surged no matter what. Someone flow tested one and found it was leaking in vacuum.

The GFB recirculating is supposedly better than the VTA in regards to surging.

1g DSM, got mine for $30, all metal, works great, stands up to tons of boost.

the tial valve does sound insanely cool.

Which Bosch were you running?

The brass piston works on 20psi KKK turbo Audi's...

I want to get 2 tials for my camaro project when it gets done.

I can give you a deal on any of our valves.

I heard what Jefe said- but I haven't got my boost over 13psi yet.

I have this one bookmarked because I read somewhere that it worked well for higher boost and being a chinese unit.

I miss my IS. :sadwavey:

Funny you should bookmark that one as it the same seller is the one I bought my current cheap one from. Problem is the piston part sticks after awhile and I'm getting tired of oiling it so frequently.

Hmmm....cheap DSM 1g or cool sounding Tial......

get the one you sold me :gay:

the HKS works on supra and rx7's. Worked on my 92, will work on yours
+1 for the HKS

does anyone here have an atmospheric dumping bov...who's tired of the noise?

my junx is recirc. and too loud/annoying

I assume this has to do with a lack of precision and excessive tolerance causing binding of the piston and cylinder- understandable when cheap enters the equation. Glad I mentioned it.

my all metal bosch dumps and was loud- but I picked up a an air filter for it and it did a good job of muffling the noise while keeping the air clean off boost

Where, and how much did you get an all metal one for? :)

All of those ebay valves are knock-offs of our units...:td:

I recently replaced my FM valve with one of these:
http://cgi.ebay.com/ebaymotors/TYPE-...QQcmdZViewItem

And I'm actually very happy with it! I took it apart and removed one of the springs to loosen it up. Now it leaks like a sieve at idle, which is fine since I'm running sans-AFM. (others could recirc.) I just lathed an adaptor to stick a filter on the exhaust so it can suck in all the air it wants. A lot of 'em include the recirc pipe at no cost.

No problems at all so far.

I have a Tial, it does sound badass.

I had an authentic HKS SSQV on my 240sx and the sound was.....meh. Some people like it and some people hate it. I liked it at first (initially enamerd with having a bov) but I guess it gets old.

I have a brand new Turbosmart V-port that is too stiff for my TT's but should be good for anything else out there. PM me if you are interested.

I'm running a remachined FM part now with just about no preload.

I'd never heard of force until you showed up here, so I figured the chinese stuff was all original and just a really good deal. ;)

With the HKS, the original 'fin' is cool at first, but a bit loud. I installed the purple fin and the sound is more stealthy.

GREDDY TYPE ARRRRRRRRRRR

Just PSSHHH. easy to adjust, easy to plumb. You can get flange adapters here and there.

FWIW, the DSM valve VTA sounds pretty cool, nothing showy, but a nice squeak and whoosh.

That is, if you care about ricey stuff like that....:rolleyes:

I can't stand HKS valve, it's REALLY obnoxious.

If you are venting then a Tial is the only way to go. Let me know if I can help you out at all.
The HKS is so fucking annoying. I think every 18 year old kid in my area has one on their STI.

I VTA'd my Bosch with a Lowes check valve for about 3 months. With the .48/.49 DSM T25, even at high boost, there wasn't enough air to make it flutter or sound cool. Just a really loud "pssstttt" like when you disconnect an air hose from a compressor. When I "upgraded" to the .80/.64 Nissan T25, it fluttered like crazy even at moderate boost, sounded good, and wasn't too loud. But after a month or so, the noise got old and I got tired of every dork in a big-winged Sunfire giving me "the eye". So I recirced and found new joy in life. All of my driveability problems went away, no more bucking... and my mileage went up from about 18 to 22-23. My wang feels a little smaller though.

just get the recirculation kit for the hks if you dont like the sound.

I got it way back when because it worked with my MAF before I ended up finding a used link

I've used Greddy Type S, knock off Type S, RFL, knock-off RFL and a DSM.

DSM was by far the best mechanically. Held boost great, sounds good dumped to atmosphere and is super responsive, plus it was the cheapest of all.

Tial and shit is good quality too but you cant beat the DSM as far as bang for your buck.

I can't handle the "flutter" noise. I can handle the poosh noise...I think.

I am going with a Forge diverter valve for this build on my Vr6. Should be pretty tame.

We are big in the vag world...

Can we get some videos of how these sound. I would be real interested to see how thry sound vta. Thanks

huge actually.

What kind of deals can you get? I really like the looks of this valve.
http://www.forgemotorsport.com/conte...roduct=FMDV004

Since you're here Pat.......do you have a spring recommendation for me? The Vr6 pulls about 20" of vacuum at idle. I will be running 10-22 psi. I have a green spring and a red spring sitting here I can choose from.

I just got one like this today, http://cgi.ebay.com/ebaymotors/BLOW-...13014931QQrdZ1

It works and fit right where I had the Bosch, But the spring is to strong for my low greddy PSI's

I got tired of paying $10 for the Lowes check valves. (I am on my 3rd one) But so far they worked better.

Which valve are you running?

I have the same forge blow-off valve as here http://www.forgemotorsport.com/conte...roduct=FMDV004
cant wait to use it it sounds awesome.

If you are still MAF and have stumbling problems let me know, I can send you a stiffer secondary spring.

Its just all black with a screw on top and doesn't say Forge on it anywhere.

Green 5-15
Yellow 15-23
Blue 23-30
Red 30+
Often times its hard to tell the green and yellow apart...
The numbers are approximate but usually work out pretty well. You want to use the softest spring possible but if you go to soft its possible for the valve to open partially due to latency and pressure drop. Eventually it will usually close but your spool can really take a hit.

Did you buy the valve from us? If it isn't one of ours don't go by colour for the springs measure the coil thickness and go from there.

fake GReddy bov :td:

It took me a few weeks but I found a decent deal on the EVO forums for a used RS unit

The 1G DSM BOV leaks air at idle, not an issue if you are recirc'ing it or are running a MAP based system.

TurboXS RFL or Tial!

I just ordered a forge dual piston bov. I can put my impressions here if you still haven't decided which one you want Tom. Pat was extremely helpful in everything when I was ordering the valve. I will recommend the forge to all my friends if the valve works out great. Thanks Pat.

well...if anyone is interested. i've got a brand new TurboXS type S bov just sitting on my shelf...been sitting there for like a year and half now, still in box, never used. decided on different turbo setup and this one wont suit me.

$90 takes it :)

TurboXS BOV are garbage!

Tial or Turbosmart!

For what they are, I've heard the ebay knockoffs work alright...anybody else agree with that statement?

Hks!

I just got the forge bov today. Sounds awesome. Holds great under vacuum, and responds extremely quick to any throttle responses. Sounds real close to how the tial sounds, at a lower price. I love it, thanks PAT.

O which one did you get? are you allowed to state the price? that youtube video was the first time i had heard a tial and i really like the way it sounds. How much do tials go for?

You're welcome.

I got this one,http://www.forgemotorsport.com/conte...oduct=FMDV004A, but in a 34mm variant. If you want the price, pm PAT! and work with him. I love the sound and will be recommending this valve for all of my friends cars. It also reacts super quick to any pressure transients. Also because of the dual piston, I see very little change in the AFR's when shifting or letting off the gas.

I have a forge on my Saab Aero, and have MANY VAG friends that have them as well. Sounds pretty good at 17lbs. I did enjoy my HKS's flutter on my Integra. But Forge is a good quality product!!!!! I may hit a Tial for the Miata WOW!!!

Steve, can you get a sound clip? How loud is it?

I will try and get one tommorrow or the next day and give you guys a link. It is just real nice and smooth sounding. Granted, it is a lot louder even at lower boost than what I would have thought. At 1psig, I can hear it pretty well. I will try and get some multiple levels to give you an idea.
