what the topic says! i was thinking of getting a new bov just for kicks, one that sounds nice... but for a low boost app, most of the bov i see says it handles 10-25 psi but the max i will be boosting will probably be like 12pounds. i was looking at the turboxs type s, but thats all i am really seeing as a possibility right now. anyone? thanks for help in advanced.

 

from what i've learned from this forum, boost isn't measured accurately psi. a lot depends on the actual turbo size. a smaller turbo will be able to reach higher psi's while a larger turbo will be able to reach lower psi's but actually be pushing more...

 

most bov's dont usually require a certain PSI to function. that is probably a desired range, but im sure it will work with any psi

 

lower boost = not as loud ofa blow off sound

higher boost= louder blowoff sound.

 

BOVs are more triggered by vaccuum, but if you're pushing a lot of boost, you need a stiff spring to keep the plunger shut. Depending on the BOV, size the spring accordingly. Tials are sized by idle vacuum, others have a low boost and high boost spring. Depends on the valve. Damn near anything holds low boost.

 

bov's can be adjusted with screws or springs...

i still recommend tial over everything...

 

sweet, thanks for the help guys. so for the most part, any bov should be able to handle 8psi good without leaking etc?

 

i would hope you dont leak on low boost...i would be more worried that your bov is too stiff and wont open up...

and he is right!

depending on the bov, it can hold more boost then others.

 

HKS SSQV is the only one I use now...

 

HKS SSQV is awsome but for ur application Id say a RFL
