Ok, I got an HKS racing blow off valve from ben and his groupbuy. I thought it was gona come with a greddy s, but neway, isnt the hks racing blowoff valve only for high boost applications???? Just curious. Will it still work if i push .45 bar? Does it make the flutter noise like the hks ss?

 

No HKS Racing BOV works with low boosts as well.....sounds pretty damn good too....

 

i bought one too, as well as dustin, maybe hell post a sound clip?

 

how do these sound?
loud woosh?
does it have a horn? is it removable like the old school BLITZ

 

Damn, this thread is old. How did it get brought back to life?

 

at low PSI a wooosh...at high psi more of a loud chirp, followed by a woosh

 

is low psi meaning less than 10 psi ?
where can i buy these?
