Blow off valve question

I was wondering if installing a Blow off Valve kit to a stock 90 supra turbo would sound decent and will it add any HP? Im looking for that PfHSSSS sound when revving and shifting. And if it doesnts sound good stock, whats the easiest way of reaching higher boost to be capable of installing BOV?

Ive already talked to project on AIM but other opinions would be helpful...thnx for reading

getting a blow off valve wouldnt give u any hp, and to get that noise u are looking for would happen by u purchasing a b.o.v. and installing it to raise the boost for a cheap price u could just buy a manual boost controller ($50).
