: Forge BPV installed

Finally got some time to do a write up for this. Last weekend I replaced the stock BPV valve with a Forge one. After hours of searching the forum I was able to find some info and dig up the part number to use. It's definitely an eay upgrade and being tuned I've noticed an improvement with WOT boost.

My car had about 75k miles on it when I vtune'd it. After a month I started hearing more and more of the "tshh tshh tshh" noise under WOT. I figured the stock bpv was starting to go and was letting all that glorious boost leak out. After installing the Forge unit, I still hear some of the noise under WOT but it's not nearly as bad. The car does feel much better too, probably because I was not holding all of the boost before.

I also have a BSR intake and the turbo noise still sounds the same as before, except now it has a more metal/tin-ny noise. Under light load throttle lift offs, it will sometimes make more of a pinging noise like you would hear some BOVs make.

Installation was really simple. The hardest part was getting my socket down next to the turbo to loosen up the clamp holding on the plastic intake tube. Once that is loose, just pull the tube off, move aside, pull off one hose, and remove 3 bolts. I did it with the engine bone cold and had no problems getting the bolts off. I didn't even need to use any BP Blaster, just a good ol' push to break the bolt free.

Info:
my car: 2007 2.0T
Forge BPV valve
part number FMDVRMR

the cheapest I found it was online at http://www.vivaperformance.com/
cost: $153 + shipping

I couldn't find any on ebay, I hear that they crop on there from time to time. The part number I bought is suposedly the newer version of the same thing. On Viva's website it was listed under the Genesis/Sonata 2.0T, guess we use the same turbo.

I did not get any extra springs with it. I am just using what was already in it and it seems fine with my stg 1 vtune.

Not a bad upgrade, especially if the stock bpv is going bad or if you are tuned. $150 isn't expensive nor cheap, only sucks that no one can see it's shiney, polished goodness.

Now for some images!

If you're still getting that boost cut noise under WOT it could be plugs or a bad coil too. I replaced my bpv with a bov thinking the same thing but didn't fully fix the problem. I'm in the process of getting newer coils and wil be switching back to stock heat value plugs per fredrik's advice from maptun. I'll let you know how that goes. I used to think it was just boost cut off in hotter temps, but since unplugging the battery and allowing the ecu to recalibrate doesn't fix it I'm thinking that my 105k coils might be the source.

thanks for the tip. I havn't felt any jerking or power loss really, just the tsh'ing noise here and there. If I can hold out till 100k for new coils I'll be happy.

I have the same one on the the boot of the car, awaiting a visit to the dealer, jejejeje, bought directly to Forge, jointly with the rest of goodies.......mmmmmmmm I ordered with the yellow spring, by mistake they didn't include it, but after an email they send me the correct one in few days.

I let you know how it goes, as with the Stage4+ ( I asked to Maptun to increase the torque to 410NM as I has the Spec clutch), I am listening a little spluttering noise at full boost, and the TD04 is really new, but I expect the diapgrahm couldn't handle the boost.

In my case I need to remove also the strut bar.

Theoretically is the forge BPV better for the car ( and performance) than the BOV setup with a block off plate? and i wonder how the forge would cooperate with a boost controller.....

One question when yo uinstalled it, did you notice if the hole with C shape on the valve fits exactly in the same place as the one in the turbo?? The dealer installed mine yesterday and said to me it doesn't fit exactly in the same place, there is a small part of the valve C shape hole that doesn't overlap in the turbo hole.

I installed the yellow spring, as Ihave the Maptun Stage4+ and once it appeared the P0033 CEL code, we delete it and it seems ok, but I am little bit worried.

As I said, you can see the alignment of the C shape hole isn't exactly the same in the Forge valve and the turbo. Check where is positioned the screw hole in the valve respectively with the C hole in the Turbo and in the Vale. In the valve it's in the middle of the C, but in the turbo it's 30 more or less moved.

Do you know if this could cause any issue in long term?

I didn't even think about the hole not aligning the same. I figured it looked the same as the oem part and was a good enough match. No issues or anything that I can tell. It still functions the same (can tell from the whooshing noise), so I don't think there are any issues with the alignment of the hole. Hope that helps you.

The c NEEDS to be lined up or it will not work correctly. It can only go on that way.

But could be aligned?? that's the thing, because when I have in my hands that part was fixed, only the cover can move and be adjusted. Check the rubber seals for example around, all that base is fixed.

So tonight I decided to take off my bpv and have a look at how it was installed. Sure enough it wasn't as good as it could have been. When you look at the turbo, the C hole would be to the right. My bpv was installed with the C towards the top.

What I had to do was unscrew the valve and rotate the nipple around so that the C hole on the bpv would be to the right and the nipple pointing up. The reason I installed it wrongly to begin with was I A) didn't think about this and B) it was how I could have installed the hose without it kinking against the engine block.

Pic of how I oriented the nipple to the C hole (there's a dirty joke in there somewhere :cheesy:). sorry for blurrycam, my camera is old and doesn't like up close shots.

Pretty much if you install the pbv with the hole to the right it will be as good as it will get.

I haven't felt any negative side effects so far, but at least I double checked and made it better :cool:

Yes.
The parts for the original Garrett turbo can be purchased from http://erikssonindustries.com
It is kit pn# 55558271-Minor. I just installed one on Thursday. It cost me $87.16. The car runs like it should now and no more bypass codes.

Be careful with the Spring!!!

I asked to Forge for the yellow spring and installed it, as I have the Maptun Stage4+(265bhp, 410NM) and after talking with Maptun they said me the boost pressure will be around 1,2 bar. After installing the Forge BPV with the yellow spring, sometimes I notice the same issue I had when the wastegate of the GT20 turbo was broken, no CEL, but the car sometimes, the first miles, pluf!! on limp home mode.

I uninstall the yellow spring and fitted the standard one, and problem solved, no more limp home mode.

Is the standard spring green?

Yes the green one is the standard one. When you look at the springs, well, let's say they are not quite well painted :confused:

Thanks for your response. Have you had issues with it leaking?

edusaab
28th May 2013, 03:13 PM
No.

At the begining with the yellow spring, It was only having issues of limp home mode, I supose the yellow spring was too much strong for the solenoid and the T8 detected an overpressure. After that, none.

Some months ago I changes the hose from the air filter to the turbo, as it was broken. THe 2003 units are different from the rest 2004-2011, and there isn't available.

I have 265bhp and 410NM of torque, Maptun Stage4(they customized the torque figure, this is a possibility without any extra cost). The only issue now it's with the nuts of the downpipe, I see it's a common issue with tuned cars in general, the nuts jump off. I purchased the stage 8 kit and next week I will install it.

I didn't notice anything strange or weird sound or similar coming from the turbo. Once per month aprox. I upload again the software with the maptuner, as it's quite noticeable how it change the response after some time.

Nice. Thanks. I think my issue was my choice of grease. I took it apart when i got it and cleaned it up and used white lithium grease on it, but today when I took it apart most of the grease was gone. My car would only get to 11 psi yesterday so I took it apart today and seen most of my lithium grease was gone. I regreased it with red high pressure grease like that goes in tie rod ends and put it back together as tight as I could. I hope it solved my issue.

I just replaced mine and Im still getting that boost cut off/sputter. Im at 115k miles and im assuming its the coils like you guys said but where do you guys recommend i get new coils. Oem replacement for autozone or does it have to be genuine saab?

Hello, I have problem with DV FMDVRMR.
My car is Vectra C Z20net Trionic8 (saab engine B207) 175hp.
I have maptun stage 6, turbo boost is max 1.35b - 20PSI
Engine get error and limp home mode.
P0033 turbocharger bypass valve-range operation.

I tried with green and yellow springs but it still get error.

C hole is perfect fits.

DV walve is new, apc valve is new too.

With the stock bosch valve is no problem.

Sorry for my english ;-)

Do you have eny solution?

SaabMick

If the stock bosch valve works without any problems, why not switch to that?

Have you tested the valve to make sure it's free and not bound anywhere? I seem to remember also that the clock position of the valve was critical to the operation. I had to use shims and the weakest spring on my greddy type S to get it to work correctly, also ended up replacing the DV actuator a few times do to them failing.

mariocccp

Clock position is OK, C hole is feet almost perfectly.
Maybe the spring is too hard becouse stock valve it moves more easily.

I recorded the sound, is good or bad?

Sounds like you're getting flutter, spring is too stiff.

mariocccp
21st October 2014, 02:42 AM
When changing gears 1800-2300rpm boost is 0.2-0.4b and DV does not open causing the error.
You're right, even the green spring is too stiff.
Finally, half the green spring was similar to the work of the original valve.

I am a late comer over here. So I had the notorious dump valve check engine light come up. I ended up buying a full forge valve kit with the three springs + 2 washers. Now I do not have any clue about how to go about assessing if the valve installed fine. there was a green spring , a yellow spring and another non coded spring already in the container valve. The instructions said you add as many you want from zero washers at the top of the spring . But the spring itself is too wide
to let these remain on top - they just fall down at the bottom near the hole. is that where the washers are supposed to be.
How do I know if this install the way it should have. I do not really see any appreciable so called boost in the power.

This is the 9-3SS forum. Are you sure you are in the right place? A BPV doesn't increase boost.....
