Ok here is the thing. My 89T2 that is well modded is only hitting 10 psi max in 3rd gear and I should be able to hit 15 psi and I have heard lately that the apexi bov has some leak issues after 9 psi.
So I am wondering if anyone has heard of this leak problem?

 

anyone????

 

i dislike the apex bov..... get a greddy type r so much better !

 

I've never heard of any leak problems - the Blitz BOV does have leak problems, though. At least the old one, not sure about the new DD one.

The Apexi BOV uses a pretty stiff spring, too. If you are leaking, you can use the adjustment on the top to tighten the preload on the spring.

You may have a leak elsewhere - best way to find out is to use an air compressor to pressure test the system.

Ok about the air compressor test. Where should I start to test the system. I want to do this because I think that I may have a vaccum leak somewhere.
