I've done countless searches here and on Google and I can't come up with any numbers. I've heard people complain about their GReddy Type S at ~15psi (possibly improperly adjusted ?) and it's only rated at ~25psi. I plan to run ~30psi so I'm not sure what way to go. I have a Type S but am pretty sure it's not going to hold the boost I plan to run. I already have a GReddy flange welded on so I would rather stick with that style. The Type R might be too much and I can't find solid numbers on what the two springs are good for (standard & stiff) as far as pressure. Sounds like I'm going to be right in between them and the new Type RS is supposed to be in between them (replacing the discontinued Type S) so perhaps it's what I'm looking for. I'm hoping someone has some numbers for me.

On my old Supra
I had two Type S and pressure tested up to 30psi and no leaks!!
Boosted up to 32psi and 30psi steady with no leaks.
They worked fine for me. Not very audible but get the job done.

I suppose I could just try the Type-S that I have here but am worried based on what others have said. Sound is really the last of my concerns when it comes to BOVs as function comes first.
