i have a SOHC vtec/turbo set up. D16y7/8 motor. .0020 mm thicker head gasket, ported head, 5 angle valve job, adjustable cam gear, high flow fuel pump, adj. fuel regulator, exhaust. When i boost, my blitz ssqv flutters when it purges. is it supposed to sound like that? I purge it at any boost level, and its the same..flutter flutter. <shrug>

 

Have you tried loosening it?

 

yup loosened, tightened. same o same o.

 

mine does the exact same thing only on like 1 lbs or 2 lbs

 

do you have a air filter connected to your turbo?

 

I think its just the noise that it was meant to make...kinda like psshs shhs shhhs shhsh shs

edit: here I have this video of a gsx-r bike pushing 30 psi on my school webbysite...does your bov sound like this? This is what my Blitz ss sounds like...

yea...that is what it sounds like...sorta....i guess its the way it is

 

Sounds like it's not opening soon enough and the turbo is backing up a little. Check your vacuum source. You might need to give the bov it's own source without anything tee'd in to it.

 

hmm...thats a good idea...i will check that

 

I used to have one it wouldnt open at all. I actually had to take it apart and relube it and it worked fine after that.

 

My vortech did that for months, tried ALOT of different methods of tight/loose... eventually I loosened it nearly all the way and now it sounds REAL nice, no more dead bird under the hood sound...

 

sometimes that fluttering is just the wastegate.. u might have ur spring in ur blow off valve too tight and it's not opening up.. i had the same problem.. i thto something was wrong w/ my bov until i loosened the spring.. it turned out the whole time i was hearing a wastegate..

 

if its the wastegate....what can i do to remedy that?
