Greddy type rs blowoff valve

[Little G]

So i just bought a type rs and i keep getting a lot of flutter when at a low rpm...I keep adjusting it but i just can't get that laser sound i always hear other people having...Am i doing something wrong??

[sesolcSTI]

Maybe ask the_mike, i know when he had his EVO he mentioned something about flutter, dont remember the circumstances though. :)

[PSI Chick]

maybe the rs sounds different on an evo, but mine sounds more like a rfl than a laser. the type s is the one that has the high pitched noise.

make sure that it's releasing at 0 or +1 psi. don't listen to the noise, watch where it's releasing. and make sure that you test it under load, not just reving in the driveway. you'll get a more accurate setting if you test drive then adjust.

[Little G]

oh...i just heard i need the recirculation kit to get that noise...I don't know if its true or not...Yeah but i am looking for that high pitch squeel noise..

[igo4bmx]

1- the rs doesn't make a high pitches squeel
2- where is your vacuum/boost source coming from?

hks senquential makes a noise like two swords clashing ( sounds like CH-ING ) in an oldschool sword fight movie scene lol i dunno if you have to use oner of the after market inserts they sell for them in order to prodeuce that noise but it deffinately gives what i think is one of the best BOV sounds availible and it also sounds like you would be highly intrested in that one in particular

haha thats exactly how I describe the greddy type S a "nintendo sword slash"

anyways from my experience... getting a good vacuum source really helps with the sound of the bov...

the hks sounds like a dying bird! lol i can't stand that bov.

[Gorilla Unit 33]

mat just keep the BOV i like it on your ride unless ur really wanting the HKS

[mysweetfracture]

the greddy does make a flutter if you are barely or not boosting. it is perfectly normal. mine did it all the time on my sr20det. other than that it was too loud to hear anything besides the blow off sound.

[wgknestrick]

First, all BOVs need to be broken in. It takes time for the plunger to wear into the cylinder.

2nd, It sounds like your BOV is sprung too tight.

Too tight = compressor surge on light lifts
Too loose = Idle stumbles.

Adjust your BOV by adding shims to tighten it up, removing them to loosen. If you have all shims out and it is still surging, cut a little off of the spring or get a shorter one.

mat if u plan on doing the above please search for professional help lol u dont wanna cut to much and f up the bov u got

[wgknestrick]

You can always add more shim if you happen to cut too much off. Go slow if you are at this point. Cut a little off, test, until you get it right. This isn't rocket science.

you dont know matt lol j/k j/k

[PaleDSM]

The Greddy valves don't use shims or washers like the Turbo XS type BOVs. Just the adjustment screw. Depending on how much boost you run some compressor surge at light boost lift will happen. You want the valve to have the minimum amount of spring pressure as possible while still holding it shut at max boost pressure.

[GSXDCY]

off topic: you arent the only blue evo on tristate

Eviloution, 11 sec evo, blue by you

[the mike]

The recirc fiting will decrease the sound a BOV makes by diverting pressure into the intake, rather than the atmosphere.

GSXDCY, he IS the only Electric Blue EVO on here.

This is StevEvo, I have the RS on my Evo. I did the single spring mod on mine and have it turned in about 4 turns from first contact. Works great no flutter no surge. Holds boost perfectly.

you removed one of the two springs inside the bov?

I would really be worried about air leaking past the bov valve when doing this...

[Little G]

Yeah i'm saying i'm the only Electric blue evo on tst(which is the new color)..

Oh, well i finally found a good sound for it but i just always thought the rs made that high pitch noise...And it is holding boost really well at high rpm's much better then the blitz blowoff...

[StevEvo]

I went from a type S to the RS on the car. The single spring mod is a highly recommended mod for the EVO on the Evolutionm website. You remove the inner spring (smaller spring). As the type S and the RS have the same spring setup, I did the same mod on the RS and it has worked flawlessly. I keep boost at 23PSI and it holds all the way to redline with no flutter or surging.

mat sounds like that wat we gotta try next

[Little G]

i know , we gotta do that soon

i did that with my old greddy type s and it would blow off every second :(

[StevEvo]

As I said this is probably an EVO specific mod. I know that an extremely high percentage of the people on Evolutionm.net that run Greddy S and RS use the single spring mod with great success.

theres a difference?

[Little G]

mine also whistles a lot when i slow down..is that normal..?

[Gorilla Unit 33]

theres a difference? yeah see the other blue one on here is like a powder blue (for example see road race's evo) and Little g's is more like the Sonic blue mustang color

[Little G]

I just can't find a good setting...I put it on hard and it sounds good but whistles so much when i slow down...I put on a softer setting and it flutters a lot...I guess i'm going to try that one spring technique..

lol ur nuts with ur bov thats all i have to say.

[criz]

can you post the sound it makes? i'm curious what the RS sounds like

[Little G]

Are you serious or was that a joke..??

[criz]

serious... the type s is my favorite sounding BOV so i'd like to see what the new RS sounds like

[Little G]

oh...i have no clue how i would get the sound on a post cause i have no computer intelligence at all.....

[Gorilla Unit 33]

ok criz we got u a sound clip.... \/

ok here it goes (the best we can come up with ...

woooooommmmm - PISH wooowoooo


....lol nahh j/p here u go, and yes this is mats acutally bov we recorded it tonight at my house

http://gorillaunit33.tripod.com/music/matsbov.wav

[criz]

doesnt work... if you'd like you can send it to me thru AIM and i'll upload it somewhere

[Little G]

damn...that sound clip actually worked on my computer..

[Little G]

ok well that one spring setup didn't work to well...My car was running like sh*t and my turbo timer was going crazy.....So i think i'll stick with 2 springs.

[UncleTom]

yeah, like was stated by a couple people, the HKS SSQ BOV makes that signature high-pitched sound. i've never heard the Greddy, but if its anything like my TurboXS, it sounds like the sound people make when they imitate a blow off valve...lol!

[Little G]

Yeah thats the sound it makes
