Ima be getting a Tial Q BOV. I dont know how to determine what spring to get in the BOV. I can go as low as 6psi spring. I was told to get a 10psi spring but I plan on running max 10-12psi of boost but will initially be running around 8 psi. Not sure if that is what is used to determine spring usage. Remember I am talking about BOV not wastegate! I know how to determine wastegate spring.
Thanks.

Oh ok. Well i know your running alot more psi than me. So i just wanna get a few more opinions. Thats all bro. I mean does boost psi not matter for the BOV? what does the spring psi mean on the BOV?

its for vaccum

Oh ok. But will our vaccum differ or will turbo tc's vacuum be similiar?

On Tial's website there is a chart to tell you what spring to use. It depends how much vacuum you pull at idle.

tc's generally pull the same vacuum on boost.. like 19-22 is generally what ive seen

so on their site it says the 11psi spring

If you really want to make sure - use a smaller spring and find out if it holds the boost and doesnt leak, the move to the stiffer spring. I would say that a 12lb spring is prob what you need though. You just dont want it leaking - do you have a boost gauge you can test w/?

wow, you guys are making this so much harder then it needs to be LOL!
