Greddy Type-S Blow Off Valve Help

[Mike98GS-T]

I just installed my Greddy Type-S Blow Off Valve.

One Problem.

What in the world do I connect this to?

I tried to follow this link, Installing a Greddy Type S BOV in a DSM Eclipse/Talon/Laser, but when it got to "The smaller nipple on the cast aluminum body of the B.O.V may be spliced into the turbo outlet pipe or into the line between the turbo and wastegate actuator. Use the T-connector supplied. This connects to pressure even when the other line has vacuum. This will activate the B.O.V faster by applying pressure under the valve seat."



Never in my life have I heard terms like that before. I have a Turbo XS Manual Boost Controller and it is attached to the nipple on the internal wastegate on the turbo itself.

So where on earth am I supposed to "splice" it to!?!!???!


I was sad... I was hoping it would sound like bov.flv video by jm1080 - Photobucket but you can't hear anything! I don't want a valve that is over the top loud, I just wanted it to make enough sound for it to be noticeable, like in the video I posted. Yes, me saying that "I WANT MY BLOW OFF VALVE TO BE LOUD!" makes me sound like a "ricer"... BUT I DON'T CARE!

Thanks for any help provided in advance!

Also, I tried this

But when I hooked it up, you couldn't hear a thing.

Then I tried to take one spring out, still couldn't hear anything.

I've checked the diaphragm, and there is no rips or tears anywhere. it's like brand new. I am running recirculated, just like the person is that I gave the link to the video in.

I was following this thread, but I couldn't find the answers I was looking for http://www.dsmtuners.com/forums/newbie-forum/291611-greddy-type-s-problem-please-read.html.

I used to have a Turbo X's RFL. But it was un-recirculated, so I bought a Dodge Garage Mod 1G Valve to hold me over until I could find a Greddy Type-S, cause I had always wanted one.

Anyways, as of now, it makes some sound. I took out the smaller spring from inside the valve with lower boost and vacuum it blows off but it's a real feint whistle. Once you get past 2psi or so it will blow of with a sound similar to "signature" Type-S sound. I might have to adjust it a bit more to get it the way I want it.

 

[Mike98GS-T]

I did the single spring mod. I know when I tried to use the smaller spring it didn't work really well. I now have it set to use the bigger spring of the two. I am STARTING to get that "signature" Type-S sound. As of now the screw is pretty soft so I can still barely hear anything. I'm guessing that the more I adjust the screw for a harder sound, I'll start finding the sound I am looking for. Does that sound correct?

 

[Mike98GS-T]

Ya think?

 

[robbo185]

IT IS NOT GOING TO HAVE A TYPE S SOUND IF YOU AREN'T HITTING ENOUGH BOOST

please comprehend this statement. You need to adjust the screw so you dont get compressor surge and you are done.

Mike, please stop multi-posting (in a row).

As a comparison, I just installed my FMIC with a TurboXS (came with it, leave me alone) BOV on it. The valve is FAR looser than my Forge unit and still will not blow off with any real "sound" until about 3-4psi, which requires load on my large snail.

Edit: About the MBC...you have it all the way "closed"?

 

[Mike98GS-T]

I have my Turbo X's MBC all the way closed. It will boost to about 10 psi almost instantly, then it will climb to 20psi very quickly. That does not seem right about your Turbo X's BOV. It's the RFL right? When I had mine on and it was vented to the atmosphere, it would blow off between 10 vacuum and 1psi. To me that doesn't make sense. If there is pressure in the system or building pressure, it should blow off no matter what. Especially now that I've removed one spring, it should make it MUCH easier for the valve to open at vacuum/building boost.

Think about it in terms of spool RPM for simplicity's sake.

I hit full boost near 5k. It takes a good bit for my snail to spool

You hit full boost at what, 3500? It is much easier for positive pressure to build earlier as the compressor spools sooner.

On my old Laser with a 16g, I could rev the motor and get the BOV to release. Small snail = positive pressure sooner.

Any gurus that want to pick apart my simplified response, feel free. I thought is was basic and illustrated the point.

 

[Mike98GS-T]

It makes sense Lando. I didn't realize that you had a much bigger turbo on your car.

 

[niddydsm]

if you want sound without any boost i suggest you get a ssq bov

 

[Mike98GS-T]

No. I do not an HKS.

Because I just set mine YAY! It makes that "signature" Type-S sound between 10 vacuum and 1psi. YAYAYAY!

Thanks for all the help everyone! Now I guess I need to figure out why with my boost controller completely closed, I can still boost to 20psi! WTF

Forgot to address this. "Closed" is not a good descriptor. If you mean "tightened down", you have the concept backwards. Backed out = less boost.

What? On my boost controller there is a "-" and a "+". I have it turned tightened down to the "-" side.

 

[robbo185]

because you have boost creep

 

[jm1080]

hehe that is my video clip that you posted in your first post

I dont recommend greddys type-s, I used to have it and there are too many problems with that BOV, and you can only get them used...

I now have an NGR Type-S BOV and it sounds way better than my crap greddy bov I used to have, it is built better internally and wont leak, check them out their brand new too

man i dont get it when mine is vented it wont blow off at all until im actually building some boost. kinda of confused about that. it wil barely blow off under about 3 or 4 psi but when im in vacuum mode i dont here a thing especially recirculated.

because your not supposed to............


A blow off valve releases positive pressure IE when you are above 0 vaccuum

No pressure, nothing to blow off.


Thats why the op couldnt get his sound because he was trying to get it between -10 and 0.


So much bad info in this thread

 

[VergeTSi]

I had that bov and it was super duper loud! It was really loud when recirculated, and I tried it without the recirc tube and it hurt my ears it was so damn loud, with the windows up. I pretty much have the same setup as you too. But I had a grip of problems with that bov. It wouldn't hold boost for #$(%! I replaced all the internal parts, adjusted it with every thread, and still wouldn;t hold boost. I finally broke down, got rid of it and got a cheap 1g bov. I crushed it to hold 16 psi and it holds amazing. Best 20 bucks ever spent on the car.

BTW that NGR type-s bov sounds exactly the same as the greddy type-s, how does it sound better? haha

If you're getting the "signature" Type-S sound between 10 vaccum & 1 psi then the adjustment spring definitely needs to be tightened. You should only hear the full bov release after 7 - 10 psi otherwise your bov will have leaking problems.

Like the Greddy Type-S always had an after whistle, sounded real annoying after a while. The NGR one doesnt have that, it whistles nicely without the after whistle. (after whistle, probably leak from Greddy)

 

[tnl]

you probable didnt have compresor surge it was just so loose it sounded like it. and the greddy isnt a very loud blow off valve compared to alot of them on the market

 

[Mike98GS-T]

?????

Now I don't know what I'm talking about? This wasn't a thread to help me get sound out of my valve, obviously when I bought it I had that idea in my head, but the valve was NOT functioning correctly when I first installed it. It was not opening under a load of 10-20 psi.

When I had BOTH springs in the valve, (and a BARELY tightened adjustable screw, maybe 3 turns from contact) even at 7 psi, and let off the throttle it would flutter/surge REAL bad. Now it blows off correctly. I was mistaken, it's not 10 vacuum that it blows off at, it's between 3 vacuum and 20 psi that it will blow off. Obviously, harder and harder with more boost. The way it is adjusted right now, when I took my recirculation tube off, it is completely closed at idle. I revved up the motor at idle and the piston does not move until you let off the throttle.

Like I said, I did the single spring mod and kept the larger spring of the two, it's fine now.

 

[my dreamt dsm]

About a month and half old thread. I've been doing some search on yahoo and came across this thread. I just got my greddy type s and it is showing the same problem. No whistle or noise at all. 3 to 4 turns on contact and i can't hear sh*t. I read the whole thread but nothing here seems to work. mike98gst, how much thread is showing from the top of your allen screw to the nut on the bov?? maybe that might help!

How about I give you my new type RS which is loud as hell and you give me yours??

Try loosening it.
