So, thanks to one of our fantastic forum members .MikeV. (he sent it quickly, provided me with a receipt, and the parts came before the time he promised, as well as them being in pristine condition. I definitely recommend him if anyone is thinking of buying parts from him. And no he didn't pay me to put this in here), I have obtained the Greddy Type S BOV. It has ATP piping, and fits in pretty much identically to the HKS SSQV3. It was a 5 minute switch at the shop, and it sits in there beautifully. I failed to get a picture of it in the engine bay, but I will get one tomorrow when it is bright again.

Here is the kit itself.


Anyway, this thing sounds beastly. It sounds like two glowing red-hot swords striking each other and sliding down the blade making sparks.

The only thing is, mine seems to be making another abnormal noise as well. When I accelerate hard, there is a noise that resembles a huge turbo spooling up, and it's not coming from my stock turbo. It's coming from the BOV. I have no idea what it is, and while it sounds interesting when you're outside the car, does kind of worry me, becase none of the Greddy Type S videos have any car making this noise.

At first I thought it was the sound of the stock turbo just echoing through the pipes, but I somehow doubt this.

Here is a video of what it sounds like inside the car. Note the loud spool-like whine, then the godly "psswweeeeeewww".
(Please excuse the size of the video. It's my stupid iPhone.)


Can anyone tell me what the heck that noise is, and if I should be concerned?

That's the weirdest sounding leak I've ever heard!

If it really is a leak, I think I have an idea where it's coming from. It might be the vacuum line.

Sounds good man!! As for the other sound it's a leak happened on my gti when I installed the diverter incorrectly, just some minor adjustment you need to do. But I am glad your happy with the greddy type s bov and thank you for the kind words! =)

What do I need to adjust? Hopefully just my vacuum line lol, because we had to use a slightly chunkier one since the original one's length was too short.

The weird sound could be your vacuum line, loose piping, (that was the problem on my gti) but to adjust the bov is the screw on top you'll need an allen key to do that.

Like I promised, I said I would post pictures of it under the hood.



The fitment is perfect, and it's rather colourful under the hood! :rofl:

Anyway, I found the source of the boost leak, and all I needed was an allen key to tighten a single screw, as shown below.


Now that I'm no longer leaking boost and the BOV works fine, this thing is LOUD. I have no complaints whatsoever. Thanks Mike!

lol i have like 4 BOV's sitting here, the type-s is a great BOV until the diaphragm goes bad, a true type-s replacement diaphragm is about $60-$80. in my evo the diaphragms were only good for about a year time span. Congrats on your setup! sounds good!

Good guess lol, yes I do have the Superlux. It's only hyperblinking because my front headlight is smashed, and the indicator doesn't work up there, so I think it's being overloaded or something. It'll be fixed real soon though.

And yes, you are also completely right lol. I live down near Capilano, and the mall there is.. well.. Crapilano.

Also, everyone in Edmonton knows that all Whyte avenue is good for is for people who have nice cars to drive down and show off :rofl:

Make sure you ziptie the hoses around the filter.

Do you need to install the end cap? won't dirt and debris get in there??

You mean that big hole with the threads? Nope, as far as I'm aware. That's where the "pshweeeeng" comes from! I don't know why those are there, but I think it's maybe for people who don't want to dump atmospheric, but recirculate instead?

Just a guess...

And yes! I will not forget to zip-tie it lol.

Uploading as we speak :D

Will post it right away

~EDIT~
Uploaded - Here you go!
YouTube - Greddy Type S BOV on Genesis Coupe
At 3:22, it sounds like you have some slight compressor surge when under light throttle. I have the same BOV and I just took it off in favor of the stock BPV because of that same problem. I intend to hook it up off the RCV (like stock) to see if it can react fast enough.

Also, what springs are under your purple hat?
