can anyone tell me if the HKS (SQV) dump valve has a chatter/staggered sound to it, instead of the normal " woosh" from most D/V'S? also i have been asked if the dump valve is the bolt on to the intercooler type for a JDM v7 sti. any help is grately apreciated. ha thank you *bows*

 

wudnt say chattery but its close, the hks ssqv is kind of like a high pitch chirp if u get me, and yeah its the bolt onto the IC type

 

thanks mate

 

is there another D/V that makes a staggered chattering noise? i have heard it on a couple of impreza's in brighton but never seem to get chance to have a chat with owners.

 

not sure, i think the Sard r2d2 D/v could be chattery?

 

i thourght this would be a relitavely easy question but, i was wrong no matter, i will have to keep on trying to find the one i want. thanks again mate

 

i've got hks bov, when it was new 3 yrs ago, it made a high pitch noise, now it like a low chatter/blow noise!!! sound ok but not that loud!

 

No, it's more of a psssstttt. The "bog standard" version will bolt onto the intercooler. The version specific for your Impreza will likely come with a mounting plate so that it will sit alongside the intercooler, at least that's what the one on mine was like before I removed it.
