Trying to find out what the blue spring is rated for. Are there other springs for this bov?

HMT-Admin

I have the offical Turbonetics catolog, and I dont see any Springs listed for the Godzilla valve. What are they rated at? suposivly, you can run any amount of boost you really want. But, I think your question is what do these valves open at? my tial opened at 21in of vac, I would assume the Turbonetics is somewhere in that range give or take a few.

Having problems not getting it open or closed?

Jared

I'm having problems getting it to close. When we pressure tested my system, at about 12psi the bov starts to leak.

Hmm, have you considered shimming the spring? you could go oldschool and crush it like the DSM guys do j/k

Jared

Be kinda hard to crush this bov since it's so big, but I guess I could shim the spring, but since there isn't another one available, I'm thinking the bov might be faulty.
