Re: air boost valve & turbo
Man I havent worked on an OBD0 intake manifold in years, but I believe its there to soften the throttle closing when quickly letting off the throttle.
Fast idle valve under the TB is for cold temp air bypass.

Re: air boost valve & turbo
The air boost valve is only used during startup. To be honest if you are boosting you would be better off just removing it and blocking it off.
OBD1 90-93 F22 Accords still used this as well.

Re: air boost valve & turbo
Since it seems it could be more of a weak point than anything else i will be removing it and blocking it off. Unless someone has a reason why i should keep it around under boost situations....

Re: air boost valve & turbo
If, for some reason, you do decide to keep it. It would be best to place the hose barb for it, in the tubing on the inlet side of your turbo.
Not the boost side...

Could i just draw from atmosphere also, if i was to say keep it...? Thanks for some fine discussion here!

Re: air boost valve & turbo
You could, however it would be unfiltered..... If that matters to you, then you could run a small vent filter on it. If it doesn't matter then leave it open to the engine bay/atmosphere.
