j255c Posted August 19, 2006 Share Posted August 19, 2006 Just block off the BPV/ section w/ a metal plate and a rubber gasket. The air will be forced to slam against the turbine section of the turbo and will make the stuttering sound (also known as compressor surge) haha. Kinda sounds like a turkey. 06 TB EVO IX SE stock turbo monster subaru hater Link to comment Share on other sites More sharing options...
Boost Galaxy Posted August 19, 2006 Share Posted August 19, 2006 I know the HKS ssqs make that noise, you can buy kits to make them fit on our cars, you can also make them recirc. Link to comment Share on other sites More sharing options...
Xenonk Posted August 19, 2006 Share Posted August 19, 2006 ^ HKS are swooshes, not studdering sounds like a dual valve.. HKS is Sequential, difference. The adapters for the HKS SSQV changes the pitch (think whistle).. I would know, I had one with a recirculating kit as well on the WRX.
