I'm planning my first turbo installation, and I need a little help with the blow off valve. Forgive me if these sound like dumb questions...
1. Do you have to fit a blow off valve? With an internal wastegate in the turbo, is it still common practice to have a blow off valve as well?
2. Does it matter where its located, or is anywhere between the intercooler and the throttle body OK?
3. I'm hoping to use quad throttle bodies mounted directly to the head. This gives no take-off point for inlet manifold vacuum. If a blow off valve is supposed to take a signal from the inlet vacuum, where can I route the pipe? I'm guessing that it can simply go to atmosphere?
Any help from you knowledgeable folk would be appreciated.
