Greddy Type-S BOV
 

Hey guys, just wondering if any of you have a greddy type-S bov? What does it sound like? I bought one after hearing a few sound clips. I thought it was going to be a high pitched squeal, but its completly different. Its like a flutter sort of, almost sounds like a rattle snakes tail.

Is there a reason one would sound different than another? I have tryed setting it hard and soft with not really differance. Any imput?

greddy-s is a recirculating bov, i find it to be much quiter than my xs-type h...but its all in what your looking for...

Re:Greddy Type-S BOV
 

the type-s has 2 nipples on it; 1 for vaccum that opens the valve and is tapped at the manifold after the throttle body; and the other you're supposed to put on the pressure side of the turbo.

with the pressure side and vaccum side hooked up at the same time that thing will scream and cry loud and ugly; i like it. With just the vaccum hooked up and low boost it'll flutter; with some pressure behind it it'll make a nice little PSHUUUAH. you can also set teh spring tension to affect the sound.

i got mine set all the way soft, just the vacc line hooked up and it screams like no other bov, all my boosted friends envy it, they all wanna trade me, trust me, well worth it.

sounds like a PISSSSSSSSSUUUUUUUUUEEEEEEEEEEEEIIIIIIIYYYY

lol, all jokes aside, thats how it sounds,

if u put it all the was soft and barley rev it, it sound like a crying kitten

ComputerJLT, where did you hook up the pressure side to on yours?

Re:Greddy Type-S BOV
 

you really dont need it, unless your up in some nasty high pressure levels

Re:Greddy Type-S BOV
 

Id just like to hear the difference. It will still function properly on low boost wont it?

Re:Greddy Type-S BOV
 

the short time i ran it i had it t'd into the feed line for the wastegate before my manual boost controller.

it bled pressure somewhere and my boost would do funny things so i said no thx;
i'll probably tap a charge pipe if i decide to do it again

Re:Greddy Type-S BOV
 

Ok well I hooked up the pressure line and the sound didnt change. I think it might have gotten a little little bit louder but thats it. Ihave the vac hooked the top nipple and the pressure to the bottom. I guess some just make a different sound than others? That or mines broken lol.

lol that rattlesnake sound is compressor surge. The BOV is not doing its job. I have a Greddy Type-S and they're a real slutbag to get them to work right. Its the only BOV that gave me problems.
