vacuum line questiion

[long84les]

if i hook up the vacuum line from the waste gate to the compresser and not have a boost controller where do i hook up the vacuum line for the blow off valve. also.. if i have a 10 psi spring in the waste gate, does the bov have to have a 10 psi spring also. hows that work?

The bov vacuum line normally runs to a nipple on the intake manifold.

I see you're an N/T so I don't know if you have added a turbo kit or have another car. The way the bov works is by determining the difference between boost and vacuum. While you're on it and it's seeing boost, it doesn't do anything. Once you get off the throttle and it sees vacuum, it opens up to release the air. The bov to intake vacuum line should not have anything teed into it either. The wastegate spring has nothing to do with the bov.

If you have any unused nipples on the back of your intake manifold you can use one of those. If they are all being used already as mine were, you will need to tee off of one of the vacuum lines.
