do all BOV'S have a flutter when you let off of the gas in low boost?
i just installed the dual port turbosmart in my MR and it makes no difference wether i set it towards hard or soft i still get flutter. does this just go with the territory of a BOV?

thanks

 

bump for anyone with a BOV?

 

The flutter at low boost (i could be wrong) seems to be normal on all VTA set ups. I wouldn't sweat it man...

 

I have this exact same bov on my MR and i have the same flutter..i think its just the design of the bov...ive seen no problems with it (been using it for months)

 

I have it on my Tial...i kinda like it.

 

so is it better to have it set hard or soft?

 

harder to aviod stalling problems with VTA probably

 

can i go too hard and harm the turbo or something else? i havent had any problems with stalling or any of the other problems i have read others on here have maybe because its a dual valve. i am kinda pissed thought the screws that hold the horn on are obviously aluminum as well as the unit it's self i was going to make it a reciric to see if i had the same problem, and the first screw i tried to back out striped first try!

 

let me get a bump for turbo destruction

 

If you can have anyway of measuring PSI on the setting make sure its close to what your psi is at vacuum. Other than that you will feel maybe a bit of compressor surge . As for the screw try matching it with a new one or getting that thing called "gra-bit" from your local hardware store its a bit for your drill that makes stripped screws usable...anywho best of luck to you and hope you get it sorted out.

 

how do i go about measuring?

 

oh yeah and on the butt dyno what does surge feel like?

 

I just installed mine also and get a little flutter in low gear. To me its not a big deal and from what I read its not going to cause any harm to the turbo. Just be glad that you don't have stalling issues like other members have had.

stock bov is good enough! there is no stopping the flutter! I only use my greddy type s on the week ends when I wanna have some fun1

 

Is your BOV a Turbosmart Dual Port or Supersonic. If it is the Dual Port you won't have any stalling problems. You want to have the spring tension as soft as possible, while not causing cavitaition of the turbo. A little bit of flutter at low boost is perfectly fine and nothing to worry about.
