I'm piecing my new setup together (geoff's equal legnth manifold, gt30 turbo, tial 40mm wastegate) and need to decide on a BOV. I'm was planning on a Greddy type S until I saw the tial. Didn't even know tial made a BOV, and I haven't seen any opinions on it. The other option is an HKS SS.

 

tial is the best bang for the buck.. It nto going ot be loud its kind of quiet like just sneeze not like any other ones out there.

 

How much is the tial?

I would have at first picked the Greddy TypeR....but the Tial is so freaking HUGE....so I'd pic that one.

Which one I would pic, just depends on the price.

see sig

 

My street boost is going to be as low as 13 psi (that's the spring I'm getting in my wastegate). Will the tial work okay at lower pressure. I heard the greddy type r is only for high boost applications, and won't even open at lower pressures. Is the tial like that? Is 13-20 psi within it's range?

 

I am running 8psi and my Tial goes off. It's kind of a whoosh sound.

 

To use a type r bov you need at least 650 to 700 cfm , depending on the spring and where you tap. Remember , this is equipment not jewelry. Say no to rice , buy what you need..if 35mm..hks ss...blitz....tial..type s.

Also bov's are referenced not pushed , the question is how well they will work based on you potential cfm , not whether or not it opens.

 

boost/psi = one thig........cfm = a completely different thing
