greddy BOV question

[reddsm00]

i installed a greddy type s on my car a few months ago...i just recently got it to stop fluttering but it sill doesnt have the gredy high pitched noise that ive heard on every other appication on a car, so far the BOV just makes just a staiit whoosh noise...ive asked around and someone mentioned they fixed it using the ssm mod to the blow off valve...what is ithe ssm mod and what do i have to do to get it to make the traditional greddy sound?

SSM mod is the single spring mod. Basically you take your bov apart and then use either the large spring or the small spring depending on how much you are boosting. Read this for how to do it.

I did the SSM on my Type-S and it whistles with no flutter. That link will show you how - you just line up one of those holes inside with the small nipple and you'll get that unique sound.

I had a similar problem with the flutter and whoosh instead of the high-pitched blow-off. I found out I had my hose hooked up wrong. It works good now, so you may wanna check where your hose is hooked into.

im pretty sure i have the hose hooked up right but iver been trying so many damn adjustments without getting what i wanted with this BOV....

just start with ~10 threads showing from the top of the screw when tightened down. adjust til you can get the whistle on IDLE...

then go out and drive and tune her until she's right where you want her
