Fitting HKS bov

[Kieron]

The HKS one I had was Fin loud. What insert do you have? Silver one was the loud chirp, purple was high pitched and long (a bit like the greddy) and without one it was just quiet.

^^^ Agreed, my HKS one is rediculously loud and thats on stock boost, i had a cheap one a while back and it was terrible, sounded like somebody exhaling loudly  :p

ryan are u running with the airbox or exposed air filters as if the filters are exposed this is the whoosh not the hks ive never known one do anything but chirp on any car

I have the purple fin and i cant even hear it. Only with the window open. As i just said in another thread I have not removed a standard valve.

Surley it cant be right? I have an airbox at the mo

Stock airbox and it is a sort of chirp i guess, but its not quiet on mine  :driving

MissRX7: Have you got a boost guage fitted to make sure that your turbos are good. If you have a boost leak or the turbos arent 100% it could cause the valve to be quieter.

Turbos Are good. Rebuilt 5kmiles ago. and they pull. Dont think there is a leak. Im positive its ment to be louder than it is

the hks will only ever chirp if u look at a bailey one it is single piston and on lift off has a very large area to expell the air..on my impreza unless u were giving it wot u could barely hear it sounded like a budgie being strangled
