The Loudest Bypass Valve
- Thread starter 87witmoreboost
- Start date
i was really really wanting to know about this myself, because im thinking of getting one but dont wana fork out the dough if its all just hype
HKS Racing Type II is quite loud even recirculated (like mine), but it's not the fastest to react and seems to surge at lower boost pressures...
One of the companies makes one that vents 50% and recirculates 50%, but I'm unsure of it's performance...

what about two bosch 110 bovs and hook one of them to a kazoo so its loud and stops compressor surge...?i bet youll get some looks...:crazy1:

I was just looking at an ad for them in a magazine somewere. I was curious myself. anyone have any experience?? Not trying to thread jack here.
I love my Greddy type s bov . It's loud when you run 12psi + boost , more boost = louder ,and i have no compressor surge either . Greddy type s is adjustable , if you tighten screw too mutch will cause compressor surge + less air escape = not loud . I back screw out where it should be at + i removed steel insert on accordian hose and port accordian hose to .900" dia and insert 1.00" steel tube and now i have .900" i/d this help air escape from bov to accordian hose quicker ( the quicker air escape the loulder bov get + less chance compressor surge+ turbo spool up quicker everytime you shift to different gear ). I'm running 17psi of boost on ct26 57trim .:naughty:Here are a few video of the Snychronic BOV and some of the tests. Granted its not on any supras but it still works the same regardless.

just a little more info, its not the loudest per say but it gets the job done...

Anyone else running the HKS SSQV recirculated? This is what I will be doing, as soon as I get my IC piping finished.

I'm using one. I'm probably the first person in the MKIII community (possibly any generation) that has used this bypass valve. I've used the stocker, HKS SSQV (the real deal), a Tial, and a synapse. The synapse is even faster actuating than the HKS was without changing anything but the BOV itself. I personally don't care for the Tial as I can't recirculated it, nor does it preven compressor surge as well as the other two do.
So this may not be suitable for the OP then, since he seems to want loud. I don't MIND loud, but I'd really rather have silence.Datsrboi;883174 said:
If I'm lining up against someone, the only clue that I want to give them that my car isn't just some NA poser is when they are watching my taillights recede in the distance.

What flange does that bov use? Is it unique or use the same as HKS? I have been contemplating switching over to it after seeing how well it works.

Alright, i'm bringing Subaru into this. Seems the synapse is well proved based on some research and I suppose this video speaks for itself:
