Leave something like that to a professional, you can burn your motor up messing with that.

The turbo is probably not able to run at a high enough pressure to get a real good blow-off.





A friend of mine got pretty good sound because his turbo was able to push over 20 PSI. With premium fuel, he was only able to run it at about 10 PSI. On the other hand, his engine was rebuilt and fortified for racing to handle that much additional power.
