HKS vs Greddy vs Blitz, which is BEST
 

hello, i'm planning on buying a set of intercooler hardpipes from cooleeze, but I don't know which BOV flange to tell him to weld to the pipe SO... in your opinion which BOV is the best? taking into account both performance and sound...any input would be great, thanks

It depends on what kind of sound you are looking for. Those are very good brands performance wise. Go to blowoffvalves.com to get a better idea of sound. It might help you decide a little. Good luck. And good choice with the cooleze pipes. I personally dont like the high-pitched whistling from a BOV, so I'd go with the Blitz DD.

Yeah, really those are all 30PSI blow offs so pick a sound. The HKS SSQV, which i have, sounds like a burst off of a flute at a high high pitch, like a PEEEEE! The GReddy Type-S supposedly sounds like an angry mouse sneezing, honestly thats the best explanation to the recordings i've heard. dunno about the blitz at all.

thats what i were using on my mk2... the hks ssqv... it sounds really nice...

ya appearantly the hks is what they used on the fast and furious... everyone seems to like that sound...

thats right... hks ssqv sounds nice... but i didnt boost that high tho... i just boosting 10psi for low end. and i squize 30shoot for high end.... on my mk2 tho... and the hks ssqv gave me nice sounds when i shift....
