Does anyone have sound clips of different BOV's at idle and under load? I know Kevin posted his RFL already... Just curious as to the different sounds they make under different boost levels. Right now I'm trying to choose between the Greddy Type R and the HKS SSQ. Any input would be greatly appreciated.

All I can say/vouch for is that the Blitz Super Sound is a "Woosh" sound and not the "kachink" sound I like more https://www.nopistons.com/forums/pub...DIR#>/wink.png

I've heard the Apexi and the Greddy, I like the Greddy much better then the Apexi.

i heard at high boost on the HKS SSQ something is prone to poping off....get the Greddy Type R for higher boost applications.

I've seen guys with Gt 35/40s and T78s running 2 HKS BOVs, so I doubt they are likely to have many problems.

my ssqv inner rubber bellows shattered/split at a boost spike of 17psi....



my rfl is working fine, link in sig (5-6 psi at a neutral rev).



kevin.

Thanks... Yea I forgot to mention I was going to run dual BOV's regardless of which one I chose. Just safer as it reduces boost pressure in half on each valve.



I think I'm going with the type R...

Greddy Type R? Because I know they make similar sneezing sounds.
