It is one of the quietest options you can buy, but it's slightly louder than stock.

I'm not sure why, but RallySportDirect stopped carrying Forge. I know that ImportImage carries Forge products, but their website has so many errors it's hard to know if you're going to get the right valve or if you will get the Mazda one.

I just bought one off of IIR from Josh and made sure it was the new diamond gasket style for OUR cars and it is indeed. I got it in black also

Perfect OEM replacement, same design, only stronger. Little louder than OEM, but not too loud. Great price too

It's the same size/shape as OEM, but the design isn't quite the same. The OEM valve has a small hole that allows air pressure from the bottom of the valve to go to the top of the valve, therefore requiring the spring to do most/all of the work holding it closed. This is why it can open at higher boost. If you do the "$0.16 mod" to the stock valve, then it operates nearly identically to the Forge, but it has a very stiff spring, which hurts response. The Forge design uses different surface area on each side of the piston so that no matter how much pressure it sees it is always held tightly closed.

Seems they once again released a new revision.

Are they the same form factor, this one seems a bit shorter than the V2.

I've been running the diamond plate Forge for over a year without an issue. I absolutely love it. It's louder than stock with my SF intake. With the stock setup, I doubt anyone would really hear the difference.

I'm pretty sure that's the same stock image that has always been on the Forge site. The model number (FMWRX3) has not changed.

Quick question from the dead i just got a used forge bpv which i cleaned and lubed. It came with 3 spring green 10-15psi, yellow 15-23 and blue 23-30 and no shims. Just wanted to get imput on the best spring for what i have, i am running a td06 20g 8cm2 at 23 psi or so tapering down to 20 psi at redline for safety. I put in the yellow spring and which is rated for 15-23psi but wonder if i should go with the blue?

im running the blue with 1 shim. im tuned for 22 psi on my vf52. no issues.you want the lightest spring that will work properly. i wouldnt use the red though.

I ended up going with the blue spring after trying the yellow and found no difference both work just fine and responce is 100% no surge or afterfire like my modded stocker and holds 23psi no problem. I like it much more then my turbosmart kompact i had a while back as well. Why would you use the shim on the blue when your only running 22psi?

Why would you use any of the heavier springs? Do you think you need to use a heavier spring to hold more boost? Because that is not true. The boost pressure holds the valve closed. You don't really even need a spring. The spring just controls how quickly/easily it opens when you let off. I always used the Green (special order) spring. Even running at 27-28psi peak boost.

I actually just ordered this BPV yesterday. I started running a Torqued Performance Stage 1 map (with Cobb SF intake) over the weekend and noticed my stock BPV seems to be squeaking under boost. I decided to replace the stocker since it seems easy to do. I ordered the BPV from Boston Motorsports. Strangely though, when you search the part number (FMDVWRX3) on Google you only get a hit from Rally Sport Direct and Boston Motorsports. I hope I ordered the right part ! Rally Sport confirms this part as fitting the '11 WRX but they don't seem to carry it anymore (as mentioned earlier in the thread by someone else). Since RSD seems to be pretty accurate about part fitment, I went ahead and ordered from Boston. I am wondering if this is a new updated valve? I did a search on Forge Motorsports for this part #, but found nothing?

EDIT: Found this For Sale thread. Looks like it is most likely the correct part # (see the last post)

I have a link in the first post:

http://www.forgemotorsport.co.uk/con...product=FMWRX3

The photo is wrong. It has a locking collar with wrench flats (as opposed to the knurled collar on the Mazda valve or the bolts seen on the Forge product page).

I believe the "DV" in the model number that you're seeing stands for "dump valve" and Forge usually uses this for their dump to atmosphere valves. Not sure why it's being used for the recirculating valve in some cases. The one on Boston Motorsports page is the correct one.

Thanks! I figured I was okay, but it's good to get confirmation from someone else. Thanks again!

Probably stands for Diverter Valve

Looking at Forge's naming scheme more, it looks like they call everything a "dump valve" (whether it dumps to atmosphere or recirculates). But for some reason they dropped the DV from the product name on these new WRX valves (VTA or recirculating).

Got my FMWRX3 from Import Image, only place on here I could find stocking Forge parts. Mine has the screw on top with wrench flats just like Xluben said. Just put it on yesterday, install took about 3 minutes. Threw a zip tie on the vacuum hose on the top port, seemed more loose than on the stock part.

It makes a small 'choo' sound even at stock boost level, but I can't hear it over the radio.

Just went by what forge says to run by psi. I am tuned for around 23.5 so i went with yellow and then blue and settled on the blue since it was for 23psi and up. It responds really well and i get no surging or afterfire so i am happy with it.

Their recommendation table makes no sense at all.

If you look up Tial or other manufacturer's documentation they explain that the spring has nothing to do with boost holding power. In some designs (like Tial) the spring is chosen in order to keep the valve closed at idle, but this is only necessary for VTA setups. For recirculating setups the valve is open at idle. Really you just want the lightest spring possible all the blue or other stiff spring is doing is slowing down the response.

The only time you need to pick a heavier spring is if you're running VTA with a MAF system, which is not really ideal anyways. In that case you're basically forced to give up response in exchange for a cool "pshhh" sound.
