When I installed my RFL, I didn't put any additional washers on it. It never caused surge nor did it flutter. Its a good BOV IMO.

 

I guess the next question is what kind of turbo setup do you have?

 

xs power t3/t4 38mm wastegate....umm what else do u wanna know?

 

Just a fyi to ya guys:

Doesn't tell jack about a turbo. Doesnt tell what inducer/exducer of compressor/turbine wheel, compressor housing (there is E, S, etc.), etc, etc.

What type of piping are you running, intercooler, where is the BOV? Etc.

 

t3/t4 t04e, 2 1/4 alluminum piping, 7x22x2 intercooler, the BOV is on the intake pipe between the intercooler and the intake mani about 14" from the intake mani.....

 

Check to see if there are any washers inside.

Some cars can never get rid of a mild surge under light throttle. As long as it isn't occurring under full load conditions, its nothing to be concerned about.

Some cars come stock with no BOV and work fine for years. Even some performance applications don't use a BOV and it runs fine forever..

 

ok it has no washers in it

 

It wouldn't hurt to move the BOV closer to the throttle body either, being at the end of a resonant pressure wave is better than being in the middle if you want to stop the wave resonance. 14" probably isn't far enough to cause any problems though, so I'm not sure that's too much of an issue.

 

Personally Ive had bad experiences with turbo xs bov's. I would sell it and get a nice one if you can afford it.
