compressor surge with greddy RS, im really getting annoyed here!!
isent the greddy RS supposed to be a good bov? apperantly not! i have it set all the way soft and no matter what the turbo surges, it surges at low boost (2-5psi) it surges on high boost (15-20psi) and im getting pissy here. i was gonna just open it up and take out the stiff spring, but then i was worried it might open when i hit my target boost of 15psi.
turbo is a GT3076R, i used to have a t3t04e and i had the same problem with the RS valve.
any opinions here? sorry for the rant.
the bov opens, but i still get surge.

I had the same problem with the greddy type RS bov. It wouldn't open no matter how soft the setting was so I took one of the spring out and it worked fawlessly eversince.

UPDATE
its official, the greddy RS is garbage in my book now.
i removed the stiff spring, not only did it still surge but it wouldent hold boost above 8psi either (yes i adjusted the **** to stiff and it still wouldnt hold boost).
so then i put the stiff spring only in there, same deal, it was either surging or it wouldent hold boost, i just got pissed off and put the dual springs back in there.
GREDDY bov SUCKS
tial here i come

Man U FTW
The RS has a tiny valve...i could have told you that on higher boost with a reasonably large turbo that it is going to surge. The ONLY way to avoid surge with that small of a BOV is to put it as close to the turbo as possible....much like the intercooler mounted Tials that some people run

Re: compressor surge with greddy RS, im really getting annoyed here!! (blinx9900)
I ended up with a generic rs and with the stiff spring out it works quite well, holds boost up to 15psi and no surge. In the future when I go to a bigger turbo I will throw a tial in there but until then the rs design is working for me.

Come on people. Don't you think you're going a little bit overboard with the Tial bandwagon? Yes, they make great products, but it's not the only working BOV on the planet. 40mm isn't big enough? I think my Blitz is only 35mm, and it works great. If you're getting compressor surge, it's probably because your vacuum isn't strong enough.
