hi guys
this is not my first time posting the same problem ,i didn't get much out of the other one SORRY
please help me out !!!

i have a greddy rs bov on my evo 9

When i first put it on with the BR air filtter it works fine ,,nice whoose and flutters at low rpm as it goes on i get more flutter less whoose sound.

After i put the AMS TBE complete lose the woosh sound and all it does is flutters dosen't matter what rpm i've try turning the spring hard and it didn't make any different
please let me know ,, what may be wrong like a leak or something that i have to fix to run it rite!!!
please help me out!!!

 

are they adjustable?

on most if they flutter to much ya tighten it a little til it stops..

cheers!

 

yes it is
i did today ,,i tigten it almost all the way it stil does it !!

 

need a heavier spring...

 

mine works the other way around. when i softened it, it reduced flutter. However on partial throttle/boost you will flutter no matter what, as with all aftermarket bovs...

Even the stock one was fluttering a little bit under light throttle... Personally i like the sound better!!! it reminds my the sierra and escort cosworths back home!!

 

Compressor surge FTL. I have a greddy type-s and rarely get flutter. Just loosen it up and you should be ok.

 

I agree, I have the Greddy Type S and mine flutters a little bit on partial throttle but is fine on WOT. You need to loosen it up to get that to stop completely.

 

my flutters on WOT Too !!!
im try to losening it up see what happend!!

 

loosening will help trust me i had the same exact problem adn i drive on the highways alot too so it was really fustrating so i just loosened it and works out fine now

 

the greddy type RS sucks. I wish they still made the type S. That was a great BOV with a great sound as well.

 

i just loosen it it didn't do me anything still flutters..................
i did six full turn from the stock setting!!!

Does it still flutter on WOT? that's strange...

if it flutters under partial throttle then you are ok. There is no way to get rid off fluttering under partial throttle... As i told you before even the stock bov flutters under partial throttle...

Even if you hear the KING BOV of the bovs, the Tial, it also flutters under partial throttle/boost...

 

mayb you loosened it too much dont loosen it 6 full turns. Play with the settings some try fully tight then go down from there i know it might be a pain in the *** but once its set youll love!

 

My TiAl flutters also. You need to get a softer spring or loosen it up. You need just enough spring to keep it closed at idle.
