What spring setting on the tial bov should I get if I have the full-race backdoor intercooler and equal turbo manifold I'm going to be running 10psi minimum on wastegate would I get bov with 11psi spring whats the difference or what should I get what are you running.......

 

the spring in the Tial wastegates doesn't depend on the boost you're running, rather on the vaccuum you pull at idle. For me i have about 21in of vaccuum at idle which on Tial's chart means i needed the 11lb spring. When you buy your Tial BOV it should have the chart on the website...

last year I ran a HKS and my vac psi was around 20-21 at Idle so would I get a 11lb spring for my bov...

 

yes, get the 11psi spring...

 

yeap the website is pretty much self-explanatory on spring rates
