I am looking to do a new BOV on my car. I had the HKS on but the would always stall. I am looking the greddy type s & rs. I was wondering if anyone likes these on there car and do they have any problems stalling?

 

I have the type-s. that is better than the rs for now. the rs does not have a recir. kit for it yet (as far as I know), I have not had any stalling issues as long as you run it recir. what mods are you running on your car? the stalling comes from 2 things - improper tune and voa. if you just like the sound get something like the RMR cone filter replacement. the open element makes even the stock dv sound like a bov. the nice part of the greddy is that it can be fine tuned to the car. it comes with 2 springs, soft and hard, and depending on the mods you can get it just right. there are tons of posts for bov's and the one spring mod for the greddy. happy hunting.

 

U have yours vented back in. Does it sound like the stock BOV or does it have a different sound?

 

You don't really hear it. When you are runnign the stock airbox and recirc Type-S BOV it is very quiet. I have one and people always ask me why I don't upgrade the BOV to get the whoosh sound...LOL.

 

before posting always search for the topic...there are 100's of threads on this....most have the type-s because it has the least stalling issues. Your bov will be very quiet and faint, if you want the lound noise an intake will make it super noticable. If your just running an intake bov and say exhaust then tuning is not "necessary" but is highly reccomended, seeing as you could wind up loosing hp or having a sligty goofy idle when you clutch the car while rolling.
Also, when you install the bov make sure you hook up both nipples!! Most just follow the us directions and leave the smaller nipple open...that is WRONG!!! If you have everything installed and have stalling problems still do the single-spring mod (search evom threads for directions).

Good luck!

PS> I have the HKS RS intake and the type-s recirced it's loud, and sounds awesome...

 

when you have a cone fliter the bov is just as loud as vta. hooking up both nipples is still debatable, it depends on the spring setup. but only one spring then do not run the lower line, but both then you may want to. i havet talked to greddy, about cars that run 20+ psi, they recom. only the large spring and upper port, the lower was not recom. for adjusting the bov - tighten it as it will go until you get compressor surge (this takes either a dyno or trial and error), then back it off a 1/4 or so. thats my setup and its perfect, plus that great sound. i noticed that it held boost better and slightly fast spool up, but my dv may have been leaking. anyhow - type s works fine

 

I am running a header, O2 housing, turbo back 3", K&N cone filter & works P2.

 

You will be able to hear the bov with the K&N cone filter for sure. My RMR is the same as the K&N. What boost are you currently at?

 

I have the type s and I had some stalling issues until I added the HKS EIDS. I VTA by the way which I have heard causes the stalling prob. Even before the EIDS the car wasn't that bad it would only stall if I popped the clutch in when tached up.

 

I am holding 20psi. I will prob just vent it back in. I have installed a few EIDS on customers cars and they really don't work well.

 

Recir helps with keeping the turbo spooled between shifts, and I havent stalled yet, and I am without the EIDS.

 

I was also looking for a new blow off valve since my Turbo XS H-34 BOV practically just fell off when i was driving, LOL, and was hanging by the vacuum hose. Now that was weird when it happened, but it was an easy fix. The adapter kit that comes with apparently unscrewed itself, and overall its poorly designed because it's just screws that are pinned to the flange. OKay well anyways enough with that i'm back to stock and looking to get a new BOV. The Greddy Type S sounds good, and i'm just wondering how it sounds and how it performs (more worried about performance). It there much tweaking involved and what not. The best price i found for that BOV is at Extremepsi.com for $210 shipped w/ flange so any suggestions? Thanks

 

There is tweaking and adjusting with the type s (lots of threads on the how to). Once you have it set it works great.

 

I have the Greddy RS and no stalling problems......I only have cat back for now....It does rev really low though, with no stalling.......

 

Found one slight problem with my Type S. Literally melted it.

Im getting a replacement diaphram from Greddy in CA sometime next week. And I will be relocating from the stock location to move it way from the heat source (exhaust manifold), but still recir. Surprising how much quieter the car is without the bov - even with the open intake, just a slow soft swoosh.

I am also replacing the spark plugs. I do not know how long I was running with a torn bov. I was having problems for about 3 weeks holding peak boost, I was making only 17 psi for a while, I was constantly tuning the type s (thought it was the new altitude (MI to NJ), or the tempature changes (winter to 70's). Then I took it and found that it was toast. Now back at 21-19 psi, I get some hesitation once in a while, feels like a misfire. I think all that extra unused fuel fouled a plug. And with all the future mods I am doing going to do a colder plug wouldnt hurt.
