tial bov spring?

[95tzlgst]

I am about to order a tial bov with my blow threw set up. My question is what spring should I get? I searched and found that most people run a 7 or 9psi spring, but the options are between a 6psi, 8psi, 10psi, or 11psi. Im guessing I should run the 6psi spring, but I just want to make sure.

Just for an example to help you decide, when i was running stock internals i was running a 10lb spring. The car only had @50 to 60k miles on it at the time, 3 months later i blew my piston rings. IMO, you should run a 6lb spring till you upgrade your internals.
(BTW: I was and still am using Tial)

OOps! Just noticed you have a GST, so an 8lb or 10lb spring would be ok for you i would think.
