because for some reason in my mind I think that having the "omg too much boost!" safety valve should be before the expensive intercooler. It probably has no technical merit at all, but my .02
Only downfall to this is A) the blow off valve does NOT and will NOT regulate boost pressure, it simply relieves it. The air on the bottom side isnt forcing it open, it gets sucked open by dropping the throttle or a combination of both. B) Im not a math major or anything but if you boosting at 12psi and drop the throttle, what pressures are now within the piping trying to blow stuff apart? 2x's 3 x's the original 12. This pressure is created all the way back down your pipes, through your intercooler, back to the blow off valve, no?
Just trying to logically think this through.
