blitz blow off valve

I just installed the blitz blow off valve in my 90 TII and it really doesn't sound any louder than the stock bov. Is there a way to adjust it so that it is louder. If not, I'm going to give it back to the guy I bought it from.

 

The hex nut on top makes it harder or softer. It will change the sound/loudness but not very much.

 

of to rotary performance forum....

 

if you have a vacuum leak or you didn't put the vacuum lines correctly it won't sound loud. that is probably the issue. i had the same problem on my 89 TII with my hks bov. fixed the vacuum leaks sounds about 10x louder

 

THAT TOPIC HAS NOTHING TO DO WITH ROTARY PERFORMANCE
