i just installed my UICP with the greddy flange...and installed my greddy type s. the bov sounds fine when i push the gas pedal hard...and when the turbo is on high boost like above 10 psi....but when i push the gas pedal a little and the turbo shows like 2-3 psi it just flutters....


can someone help me?

ty.

 

If its only happening at 2-3 psi, why are you worried about the fluttering??

 

well i don't always push the gas pedal hard...and the 2-3 psi was just an estimate.
when i push it in softly..and then let go once i like reach the speed limit...it makes the fluttering noise....this did not happen on my old HKS knock off BOV...that bov always produced a wooosh sound even on low throttle..

 

just get over it , all greddy bov's do that on low boost. mine as well...

 

oh really? ok then that's fine...i thought there was something wrong with mine...that's why i asked...thnx mitsu420aT..oh btw check ur pm.

 

The reason the HKS let out a loud "whoosh", even at low boost, is because it incoporates a "larger" and "smaller" valve. The smaller valve handles the low boost situations.

BOV's like the GReddy, 1G, etc, use only a single valve. It flutters, because you're releasing very little boost. Totally normal.

 

thnx very much mitsu420at and boostlogik...this info helped me out a lot!! one less thing to worry about from a million. lol.

 

Good info!
