Type S BOV

BKs50trimGST · 03-30-2007

When I installed my new Intercooler I ran into a few problems. My Greddy Type S Bov was not holding boost. So I then replaced it with a 1g crushed BOV, now my question is... can i fix this BOV and with what size spring? I was told I can only buy RS springs for this now, this will most likely go into my 1g AWD project. Any recommendations for the spring i should order? I looked on the Greddy site and i seriously have no idea what spring would be good.

The type s should have not problem holding any amount of boost if its properly hooked up, and did you do a boost leak test to find this problem?

Did you adjust the Greddy BOV? You know it is adjustable right!

X2 I always thought the Type S could hold boost up to 25-30 psi without leaking?

Is it a real Greddy Type-S or an eBay Greddy Type-S?

Yes, it can hold 25-30 psi but it is adjustable.

it's a greddy type-s and we used a vacuum pressure tester, when we pumped air into it the pressure didn't hold, it decreased pretty quick, we adjusted it and nothing seemed to work, so then i just crushed my 1g BOV off my non-running dsm and threw that on.

Are both of the springs still in the BOV? Sometimes people will take out the bigger spring inside of them if they are running lower boost levels.

you more than likely have a riped difram in the bov

BKs50trimGST · 03-31-2007

i'll have to tear apart the bov tomrrow and take a look.

how do you know if you have a ripped difram? and if it is ripped can you still buy to replace it?

The diaphragm in a Greddy RS bov is black and if there is a hole/tare threw the diaphragm the bov will not work right, you can buy just the diaphragm for a type RS so we might be able to get the type s diaphragm.
