Which B.O.V. for high power I am piecing together my kit and was wondering which bov you high power guys are using. I am leaning towards the turbonetics RAPTOR or the GODZILLA. I am planing on eventually in about a year building the motor and making 1000 horse .I am not looking for something you would hear a little whistle from,I want on that sounds like a real race car. Car info in sig but thats all going to eventually change.l

With all the experience I've had in turbos and such I've found the Tial 50mm to be the best so far.
I've gone through the HKS SSQV, Greddy Type S and type RS, TurboXS RFL (shitty), HKS type 2, APS dual vent (that one is a damn good piece), Turbonetics, and Tial.
The APS is a great BOV, but the tial seems to be the champ for higher boost applications.

This is something I just dont understand. Why would you need to adjust the PSI in the BOV? I thought that as long as its under boost it should stay closed. Then when the throttle closed and created vacuum it would open and release any pressure thats in the system. Doent the wastegate control PSI?

Cars will be various amounts of vacuum when you back off the throttle.
A normal car is around 18 to 20 range or so and then you add cams and stuff your vacuum drops sometimes a lot so that would be why I guess.Most blow offs don't have springs they must adjust to a point but some of the blowoffs have problems with higher boost levels.
I think just about any bv would be fine for 5 to 12psi or so mabye 15psi.On cars like my talon guys running like 30psi can have problems with cheaper ones.
The tial are very good and are used on most serious turbo builds.I bought an hks ssv which would likely be fine for lower boost applications but am selling it and getting a tial since going high boost in my 97 talon.The tials are not too expensive really either.
The do vent to atmosphere so would think they are reasonably loud.If you want super loud there are ones like the turbo xs rfl..nicknamed real f##king loud..!
Some may thing loud blowoffs are ricey but to me they are just a cool turbo sound effect.I like them.

^Some do, some don't. The SSQV and the like are pull type BOVs and don't have springs. They claim they don't leak, but the truth be told they leak but there isn't anyway to fix the problem. Yeah the Tials are usually just a better piece, plain and simple. I don't like the sound of VTA but the Tial sounds pretty gnar.

I kind of see now ,so if my car pulles 10 inches of vacuum when the throttle closes for example I would need a softer than 10 pound spring.Is that right?
