Thread: Compressor Surge?

i was reading this mod on other forums, a few people said it wasn't recommended that you should do it, but i mean I guess if it works? I'm prob gonna replace it with a better bov (a genuine one at that lol) but hey, might as well try it

Slap on an avenir recirc valve and call it a day, no need for unwanted attention on your dd

I have one of these id send ya for $20 shipped with the pipe / bov / flange and all lol.

Do those bolt to the Greddy style flange? If so, rock and roll.

That im not sure of but im not using it so id toss to whoever for $20 w/oem flange

Do what bolt on the recirc valve? I'm new to boost so i'm kinda want the blow off sound until i get sick of it (if thats possible) or want a change. With the synapse I can get an adapter for the greddy flange so i'm prob just gonna go that route and I believe that is a no adjust bov

I've had two Greddys (Greddies? lol). I took out the larger spring (the thread I saw recommended leaving the small spring) and adjusted both BEFORE ever using them. Both worked beautifully. I actually had surge problems with the DSM valve that I had previously, but it was crushed (a common 'mod' for those).

Anyhow, here is what I did:

How do I adjust type S? Searched! - SR20 Forum

And here is where I did it (with pics):

If you take out the larger spring it will leak under high boost. take out the smaller spring and tighten the tensioner.

Fair enough, that probably would be a good idea for bigger setups. I've always run 10-15 lbs so I didn't run into issues. I've still got the extra spring just in case.

The thing I hated about the idea of bovs is that when it releases pressure or metered air it runs rich for just a second. That is why I am happy with my recirc valve. But if you want the whooopshhh sound they have an app for that.
