Compressor surge
Mods in sig.
I have a greddy type rs bov. Ive had compressor surge with the BOV on its softest setting, and the hardest setting. After some research, I was told to remove the small spring inside the bov. I did. Still compressor surge with the BOV on its soft setting.
The BOV is right above the transmission, close to the throttle body.
Any tips?
Also, for some reason, my radiator fan stopped working, again. I just replaced the switch which seemed to fix the issue, randomly driving around, my coolant level spikes. I do have a leak in my radiator, so I'm not sure if the lack of coolant would do this.
Any help will be appreciated.

Re: Compressor surge
If you have a leak you have air in the radiator system. Those pockets of air throw off the fan switch thermo sensor. Fix the leak.
Post a vid of the compressor surge. Could be a leak in the charge piping. Double check every connection and intercooler.

is this the sound youre talking about? because what you posted is flutter, not compressor surge. surge happens when the turbo is trying to push more boost than it can handle at a certian speed or something like that.

compressors stall, not flutter is what I mean.
compressor stall happens when the turbo is making more pressure on the compressor side than on the exhaust side (lifting off with a stuck bov)
surge happens at wot usually, and is caused by the turbo pushing more boost than the engine can use for a given rpm. so the turbo starts making a chirping fluttering noise as the pressure builds up in the intake, exceeds the exhaust pressure, surges and tries to reverse direction (the loud chirping noises) then intake pressure drops, exhaust pressure then becomes greater than intake, builds up too far, etc etc. its an oscillating cycle.
maybe your bov is damaged and not venting properly.

Re: Compressor surge
Where is your vacuum line going to from the bov ? Is it a real greddy? If your vacuum line is hooked to a Tee with another line for the BOV ditch that and give it a dedicated line from the manifold

Re: Compressor surge
you say you have the soft spring installed and the bov is on its softest setting? now does that mean you backed off the adj stud all the way out? if thats the case, like you said, i'd check for a leak in the line somewhere feeding the bov

Re: Compressor surge
The flutter doesn't bother me, but under full boost, its nasty compressor surge. I'm going to replace the intake manifold vacuum line. I'm also going to inspect the diaphragm since these bov's are notorious for ******* up.
Heres actual video. I would have stayed neck n neck if I didn't bounce off my rev limiter (first time going WOT with this tune) And yes, that is coolant on my windshield. At first I completely forgot about the leak in my radiator, I thought it was oil
So, this seems like I have "flutter surge", does anyone agree?
