Okay so Tial has a chart that shows at idle depending on your vacuum what spring rate you should use. The problem I have is that I am planning on putting my whole supercharger, intercooler, blow through MAF, and BOV on all at once. Anyone know off hand what size spring I should get? Or can I test the vacuum as the car sits now without the blower on? (I doubt it)

Think I found the answer... Looks like all supercharged applications just use a 3psi spring. Correct me if I'm wrong.

Yea im doing the same thing and i was told its the 3 pound spring. you going with the 50mm tial or QR?

Old thread is old. This was from 3 years ago. I used a 50mm Tial and the 3psi spring is the one you need.

How did you like the Tial 50mm? how was it at part throttle?? and where was it mounted?

I love it and will continue to use Tial as my BOV of choice. Basically the BOV stays open when you don't have your foot on the gas. Once you put more then roughly 25% on the throttle it will close up and allow you to build boost. I had mine mounted on my intercooler piping just before the intercooler.

So in a way it kind conserves gas lol.. thats great.
