I though that you already had installed the Green...what's taking so long?

 

Since this thread has gone a bit off course and we're discussing BOV's and DV's. Maybe someone can enlighten me. Since installing my Green, I get this air escaping, hissing type sound when I let off the throttle driving under light load conditions. I don't know if it is my IX DV fluttering or if it's compressor surge. How can you distinguish these two sounds?

EDIT: Maybe my car always had this sound since switching to the Green, but I never noticed it with te stock airbox. I noticed it for the first time after installing an open air, pod style, foam air filter.

 

Did you try adjusting it? My car started suffering from surging after I installed the intake and I loosened the Forge RS until it calmed down.

 

surge sounds like a choo-choo train. like cha-cha-cha, pretty loud. you have you're DV in the right way, don't you. not saying you're an idiot, just something to check. they've been installed backwards by people on numerous occasions by accident.

 

Oh yeah , and re- greased it and I sent it back and got a new one . Same stuff each time .
But it did sound cooler the the stock IX bov .

 

right, I know it's not ideal, I'm just wondering if anyone has done a project low buck 20G LT/Green route and had success with it.

 

Its definitely not ideal but its also pretty senseless. You can get a metal EVO IX BOV for around a hundred bucks and even cheaper used. No matter how budget you are, you should have at a minimum, an EVO IX metal BOV.

 

I agree whole heartedly but not everyone else does. I figure someone is doing this on a budget, but after reading a couple of responses to my question, I'm guessing they aren't going to speak up for fear of being pelted with eggs

 

I gotcha. It's just that the turbo is going to cost a minimum of $1000 so cheaping out on a $80-100 BOV doesnt make much sense.

 

I know this is still a little OT, but holding boost is a closely related subject...

Having had problems with all my DVs over time, I made a tester out of random parts you can find at any HW store.

Here is a pic, with a Greddy RS temp installed for the example:



I just plug it into my air supply, and slowly turn up the regulator and watch the PSI guage.

Here is what I found:
My stock plastic DV - started leaking at <10psi
My crushed metal MR DV - started leaking at 20psi
The RS pictured - leaked almost immediately; it has a ripped diaphagm. so no surprise..

Note: by "leaking" I mean you could start to hear the air escape past the seat seal.

I am now waiting for my APS to arrive, and this is the first place it is getting installed, not the car...
Edit: fixed bov reference

 

ATP??? do you mean APS?

 

Good grief YES !!!
Too many #$%@#$% abbreviations out there

 

ATP? For a moment I almost choked on my sandwich

 

Umm, don't get me started

Let's see. Stripped studs in the turbo I bought. Needed to get them extracted. And then I needed to get the threads re-tapped. And then I got a custom port job on my hotside. And then I sent my hotside to get coated and SwainTech is busy right now...so that was another 3 weeks. My hotside should get here by the end of this week...so in the next 3 weeks I will get everything installed Finally.

 

Tom,
Nice pulls. Seems like a torque monster. Any 1/4 or dyno coming soon ?
