Aye, do you guys know if the BLITZ BOV sound adjustable? I want it louder. It seems to be the same volume as stock, but with it's own distinct sound. Any info would be awesome. BTW I'm running seq on the twins.

 

You can increase or decrease the spring pressure, while I doubt it would make it much louder it will make a difference in the way it sounds.

 

How do you do that?

 

I never have messed with this BOV before I got it from my friend last night since he's ditching his FD.

 

On top of the BOV is a lock nut and allen set screw(typical setup may vary) any way you loosen up the jam nut and if you run the set screw in it increases the spring tension, backing it out decreases the spring tension. You'll have to play with it to get the results you want. I believe the terms soft for less spring tension and hard for more spring tension is used for the type of air release.

 

BOV sound is relative to the amount of boost you are running. i.e. if you are running 20 PSI, the same BOV is going to much louder than running at 10 PSI.
