Ok so I decided to go with the Turbonetics kit but I would love to have a loud,sweet sounding Blow-off valve. I see the Turbonetics kit comes with a Raptor BOV so just wanted to see if it is loud or rather quiet compared to the, lets say the HKS SSQ BOV.
I'll be running about 10 psi.

 

All recirculating bov's are going to be more quiet then an open air bov.

 

Is it possible to make it atmospheric or will that cause it to stall??

 

Turbonetics is only recirculating. Someone on here put a greddy bov and it was alot louder. Maybe he will chime in here

 

DTRUONG... need your input!!

 

Yea read this thread, that guy was sucessfully running the Greddy Type S

i think it sounds just right, Not loud like the turboxs RFL BOV if you heard that yet. Just put it this way, if you want the sleeper with no whoosh, get another BOV. If you want a lil nice whoosh and flutter...then this BOV is perfect for you. I personally love it, I like to drive by other v8's and hit the gas a lil so they can hear what i got.

 

Awesome... would love a sound clip though. Wonder if the HKS SSQ would work??

 

yup if only the HKS would work, i would change it. but i like this BOV right now, its ok, i dont like attention from other people.

 

I second that!

 

The HKS flange is totally different then the Turbonetics/Greddy..

You would have to weld and cut, then repowdercoat your pipes...unless someone makes a greddy to hks adaptor..(doubt it)

Id personally stick to what we know fits..

 

The Greddy Type S, Type RS, and Type R all fit to my knowledge. That being said I love my Raptor...
