I'm wanting a bigger turbo an I'm probably going to go with the Hahn s20g but I was just wondering what BOV I should run with it? Looking at one of the HKS ssqv but I'm being very indecisive. For all you who have the 20g what BOV are you running and do you have any videos so I can hear what it sounds like? much thanks!

 

I have a BNR and went with the synapse BOV. love the sound, no whistling noise at all. I have mine recirculated though, so its not that loud.

sounds similar to this, but mines quieter.

i had it when i had a 20g and i loved the sound of it during spool, it was pretty loud too.

 

You had the ssqv? Which model was it 1,2,3 or 4?

 

Yeah. Sounds nice I hate that little whistle noise lol but they have a sound changer for th HKS that takes that whistle away.

 

yea i had the ssq 4 i think.

 

This is the most popular option we sell, great BOV.

 

You wouldn't happen to have any videos of it?

 

Cool I'll definitely keep it mind thanks!

 

Ssq 3

From my personal experience, I had a synapse BOV and i always had trouble with it. It sounded like Synapse BOV Flutter - YouTube but it was louder lol.. tried loosening the springs/doing different hose connections etc but it wouldnt go away. so i bought a tial and used their lightest lb spring and it went away completely. who knows if my car is just retarded or what though lol.. i have an S20g also.

 

See that damn high pitched noise I don't really like

 

The tial type Q is awesome i love it and when i shift under 3k it sounds like my bov is laughin kinda funny when honda's pull up next to me revving.

 

i personally have a thing for tial bovs or greddy type s

 

I like the greddy but never heard one in person when i heard the Tial Q and ordered it the following week.
