^ It blew open do to operator error. The size of the piston had nothing to do with it.

Yes..... because switching from a MAF based tune to a MAP tune changes the sound characteristics of a BOV.... riiiiight. </sarcasm>

You made me lol.

But seriously Bov will only work with out ill effects on a Btbt or a speed density/map setup.

Hmm very great explanation. I also have the same bov and now seriously thinking of putting the stock bpv back on. Thanks again. I will put it back on tomorrow and let see if there is a different. I have the bov for about 7k now, no problems what so ever but according to the forum, the stock bpv is better so I am just going to go with what people say. I got the bov for personally just the sound.

I thought I would share my BOV thoughts.

I did research and a lot of it. I thought to myself, what the hell let me try it and see what I personally think. So here it goes..

1. HKS SSQV BOV was my choice.
2. It was a lot of money for nothing more than a nice, cool, some what annoying sound.

3. The Install and what I found.

3a. This BOV is great in the field of quality. It was made nicely and you can tell the BOV did not have cheap engineering written all over it.
<o></o>
3b. The install was simple, after all it was a direct bolt on and took minutes to install. The only hard part; that damn C Clip, however with the proper tool it was in place within a min. Everything lined up correctly and was simply nice and safe. Came with all the proper parts and even clamps to clamp down Vacuum lines.
<o></o>
4. How was it?
<o></o>
4a. First; I drove off got in to boost ASAP, after all I wanted to hear the sounds and test everything. Voom Psssst and Car went dead. LOL! Yeah pretty freaky; ended up being the C Clip which was not seated correctly and came loose. I fixed the C Clip and made sure it was planted correctly. After all, it was my first time working with the Clip and pliers which clamp it into place.
<o></o>
4b. Clip is in place and no issues while I drove around, loved the sound.
<o></o>
4c. Idle time: Well, to be honest I was expecting the worse after reading peoples posts from several forums. When the car died from the C Clip not being seated correctly; I figured that was what everyone was talking about. The IDLE was a bit bumpy, really nothing I would consider annoying but still nothing like the stock BPV.
<o></o>
4d. Drove around for a week with the HKS SSQV installed. It was nice and I did enjoy the sound, but still, the car did not seem to enjoy the idle. Like I stated, it was bumpy but we are talking minimal. However, there was a clear misfiring feel to the car. Never threw CEL or anything to that nature, but something was not happy.
<o></o>
4e. In between shifts I did not notice anything or any loss, gain, or anything but the noise.
<o></o>
5. Took it off, drove around for a day and instantly noticed the difference. Sure minus the sounds and all, the car seems a lot smoother and idle is nice and not bumpy.

6. Conclusion, my HKS SSQV is going up for sell. Sure I paid a good amount for it but to me sometime you have to try for yourself and learn. In ending this write up, I will say the difference is noticeable and the car enjoys full recirculation. The HKS SSQV is a great BOV, but the way the car is idling under its command; well it’s just not happy.
<o></o>
7. Lesson Learned: It was fun, minimal issues on my behalf. However, stick to the stock BPV. The car runs better and seems to be happier. I should mention that I did not loose boost or experience any effect while in boost.
<o></o>
8. Try it yourself if you would like. Like I stated; sometime you have to experience things on your own and there is nothing wrong with that!
<o></o>

aahh but since yout getting a gt40 its all up to you what sound you like there are 50 bov and that i know of with all different type of sound.. youtube each bov.

Well after so much searching for a bov that would hold 23 psi. I bought the hks. At first I was thinking that I was going to have the same problems I used to have with the txs. With the txs bov, you would blep the throtle a couple of times and the car would just shut off, and in betewn shifts the car felt so sluggish. This is caused by the single large valve opening for every instantace that you backed off throttle. If you would over thigthen it would cause compresor surge. With the Hks I cant say that it is all gone but it was minimised. To the point that I had to reference to my logs and see it there. After some more testing and implementing SD, the car is strong and pulls out hard on every ocation. No slugish feel and no powerloss. Basicaly I like the sound of the Hks and how it perfroms.


Ps to the new users looking at this thread; By no means im sugesting that a bov is good for a car runing Maf based fueling. My experience while testing while I was on Maf was that everytime I would back from the throtle from going into WOT, a very rich spike ocured that would make everything slow down.

It's not the sound I'm going for, I want something that won't kill my $3400.00 turbo. I heard that Recirc's work the best for the STi, and my tuner recommended this BOV to me but I thought Id get some other opinions.
