Maybe adjust is not the correct word. I bought another FD several weeks ago and the BOV just dumps under throttle, rather than hold. The car has a T-66 and an HKS bov. There is no vacuum hose connected to the bov! Isn't one required?? Also, the bov is mounted on the downwind side of the IC (a very large horizontal mount NPR).

The bov has a bolt in the center that looks adjustable. I don't know exactly what role the bolt plays......still learning.

Any answers??

 

The bolt basically adjusts the spring on the inside of the bov which determines how fast the excess boost pressure is blown off. As for not having a hose on there, I would look into that, I have never seen a bov that didnt have a vacuum hose so I am sure that is your problem, got any pics of the setup??

I hope to be able to post some in the morning. I am curious about several things.

Thanks.
