Do I need a blow off valve?

I need advise and opinions on blow off valves. I do have the PSSSSSTTTT sound when I shift so I suspect that is pressure spiking (but it sounds so cool) and will shorten the life of the turbo and what other problems can it cause? Did I mention it sounds so cool, oh well so what should I do? Since it is not CIS I can vent to atmosphere and I am thinking I can weld a flange on to the turbo outlet right below the intercooler it is stainless. Pic of motor to give ideas.

" Porsche there is no substitute" I always liked that saying. Air cooled is the only way to go!
