RFL Fluttering WTF! Noo!
 

I just had the TurboXS RFL Type-H Ooodila what ever the ---- else is in the title put on my car.

We didn't have a gasket to seal it on the mount, so I used copper 888 compound and a piece of cardboard, I don't think its leaking air inbetween the intake pipe and BoV. But the fucker is just fluttering, and not making the full dump truck noise at any point of boost (I'm running upwards to 13 psi right now). And its driving me nuts.

Does anyone know what the problem could be? Do I need to shorten the spring in there? or crush the valve a little?

can you adjust the tension? maybe its to tight?

Re:RFL Fluttering WTF! Noo!
 

No washers installed, I just read up a little bit about a guy having problems with his on his WRX. Said that the BOV would not open up until he reached 40% or more throttle and below that it was fluttering his turbo (causing the compression to return). He kept trying to shorten the spring but it kept making it require more and more boost to activate. I'm really wondering what the hell I can do because I don't want this ---- blowing air back into my turbo.

i think the rfl you have to add washers to tension the spring more, its not adjustable by turning a knob. and if its still fluttering, you cant really soften it more cuz of the spring inside. i heard you can cut a little off the spring to releive some tension(soften) the bov so it wont flutter so much. check to see if its not stuck or jammed by dirt or anyt other ----.

yeah I'm going to cut the spring and shorten it about an inch and see if it works. I think these BOVs were really designed for guys running minimums of 15 psi.

hymmm? my bov is a turbo xs knock off and it flutters when i run a filter on my turbo but when i run open turbo or just a screen it blows off fine. i might cut it slighty and hopefully that'll work :-\

Re:RFL Fluttering WTF! Noo!
 

the rfl is adjustable ;)

Re:RFL Fluttering WTF! Noo!
 

what makes a bov specificaly used for a cerain boost level? they are all operated by vacuum, not boost

???

Re:RFL Fluttering WTF! Noo!
 

yup just set it softer a lot softer

Re:RFL Fluttering WTF! Noo!
 

Doesn't the boost help over come the spring and more the piston along with vacuum sucking on the other side. If the spring is really stiff, it might require more boost to help push the piston open and overcome the spring? That's my guess.
