RE: Blow off valve for boost control
I would set it up like a friend of mine did - a seperate exhaust system complete with muffler,that should control the noise.Anyway,it has to be noisy so I can hear over the boom box!
The vehicle in question is a 1987 Daihatsu Charade GT ti,DOHC,3cyl.Not totaly rare,but thin on the ground in my market.

A bov can regulate boost to some extent, but it doesn't do a good job of it. With an inactive wastegate (closed) the turbo will generate as much boost as possible. The engine will most likely not be able to handle the boost pressure. If you have the BOV vacuum port connected to the intake manifold, it will maintain compressor pressure x psi above manifold pressure. It will bleed off the extra boost, but if you floor it, you'll still get full boost. Using the throttle to control boost like this is a bad idea, you'll end up wiping out the thrust bearing in the turbo because of the large pressure differential across the turbo. (happened to me a few times until i figured it out)
So... if the wastegate can is still there, and you can move the arm, then i can help set up a boost controller for you.
