BOV Question

I was intersted in how the BOV was working on my 87 Turbo. I noted that the BOV is in a tube that circumvents the turbo - which is where it should be. But, my question is regarding the small tube coming out of the top of the BOV. This extends across the engine and connects to the engine on the driver side? What is this tube, what is it going to and why?

I always assumed these protected against overpressure and dumped air if the pressure was too high. I would assume it would be save to just dump under the hood?

I have also been in some other vehicles and the BOV has that lovely "psssss" sound but the supra lacks this. Any way to get it?
