Blow-off valves - Toyota Nation Forum : Toyota Car and Truck Forums

hey, i was wondering...

I watched Tony's in-car vids, and the blow-off valve was loud as all hell, which is cool, but i was curious:
which type of BOV makes the quieter, more 'hiss' or 'tssss'-like sound vs. the loud 'woosh' like Tony's?

as what i heard and read from magazines...
Blitz blow-off makes the best sound...

ít's like "cheezzzzz"

It also depends to what and where and how you pipe it.

HKS Super Sequential?

The link below has some samples of what it sounds like.

I have a Blitz bov (older one with a horn) and its loud, but I like it.

actuially the HKS is pretty loud... you should hear what 35psi sounds like going thru an HKS ... You can hear that thing 2 to 3 blocks away... I'd say the quiter would be the older HKS unit and the Blitz dual drive...

I love the HKS Sequential BOV.. Thatw ebsite is awsome, it's great how you can listen to what your BOV might sound like before you install it on your car..

But HKS Sequential BOV for sure..
