Generally speaking the higher the frequency of the blowoff the less the flow rate. I am not saying the louder because that is different. Just as a general rule of thumb though the most popular sounding BOV's do not have extreme flow capabilities similar to some of the BOV's offered by say TurboXS, Tail and Turbonetics.
While I would prefer to have one capable BOV over two I think that two can look really nice especially since some of the higher flowing BOV's are huge and can look bad in themselves and be hard to fit in certain locations.

I'm running the HKS SSQV on my APS TT, its loud @ 9psi I love it.
I was thinking about running 2 on my built setup, but I'm not sure if it I would really need it. Might just be crazy loud then.

I did a write up recently (use search) on how to mod a greddy type RS so that you can get more lift and more duration at lower boost levels, for a more effective blow off. Basically, you are lower the spring pressure so that the valve opens sooner, opens wider, and stays open longer.
on a side note, there is a guy on these boards with 3 HKS SSQV on his G.....but only 2 are active. I guess he had the 1st one installed and realized he was still getting a fluttering (or compressor surge), so he had 2 more added (one on each charge pipe, prior to the intercooler.) but then, he left the original one on because he wouldv'e had a hole in his pipe.

HKS has a good write up on the SSQV at this link:
http://www.hksusa.com/products/more.asp?id=792
No expert in BOVs, I chose this one because of the 2 stage valving described in the link - useful at low boost to my understanding - esp. because I was running stock boost of 4.6 for the first year or so...it seemed to make sense to me. Are other BOVs sequential like the HKS? BTW, it appears they must be coming out with a new one as the old one is on sale.

MIAPLAYA - Given that you personally don't like the HKS SSQV, why do you feel it necessary to punch on eveyone who's got something to say in favor of the unit? I'm sure the TN BOV is great. I'm also positive that there are BOV's (Apexi, TiAL, TurboXS, TN, GReddy, etc.) that may perform better when comparing apples to apples, but it seems as though anyone who states any sort of opinion otherwise is open for your debate.
No offense, but lighten up...
For the record: I ran the HKS SSQV with my GReddy TT and loved it. As many have stated, at the boost levels that most of us are running it's more than enough. If you're running 16+ psi, then I'd personnally recommend a TiAL unit. But that's just my OPINION.
