looks identical to the stock bosch one, just made of aluminum. not sure what i will get as far as a spring, but i just wanted something that would hold up better than the stock plastic one... this should do it. good price too.
It looks like a knock-off of the Forge valve. You'll have to let us know how the quality seems to be. The price is definitely good, about half of what Forge wants.
Mike D has one just like this - I tried it out for a week when his car was out of comission and it worked wonderfully - much better than the stock unit and much cheaper than a BOV with very similar benefits.
x2, awsome valve, never brakes, very very well made holds more than 30psi without any spring replacement, and still opens at less than 1 inch of vac. . Saabeh and therealET also run similer valves. really a great investment
The sigle piston forge design is good and simple. I can see a knockoff working anywhere from great to OK with a similar deisgn. I'd assume its servicable? If so then it should be pretty decent for $50.

I personally like trolling boards to find people selling real forge units in the $70-100 range...but if I don't have time for that, this might be a good alternative!

That valve works amazing as I used to have one. It came with 3 springs and 2 washers. I never had any problems and it held boost and was very responsive. The fact that its not a legit forge valve didn't seem to affect it at all.
ogh man, i took a chance in twice on ebay with bov's figuring i could make them work... they didnt. I got a forge atmos knock-off. Barely ever opened. I put in forge's lightest spring and it opens *better*. It is still not constant.
The other one is a hks ssqv knock-off. I know that it doesnt seal on the vacuum hose side. As in it doenst hold vacuum and therefore will not open. I've already cracked it open twice and i cant get it to seal any better.
It sounds like you found one of the few that will function, congrats, but do be careful.
hey guys,
got the valve installed tonight and did a few runs. sounds awesome, but don't think i have the right spring in. i'm running about 2-3 psi lower than i was before. it might just need to be worn in a bit, but i'll play around with the different springs tomorrow and let you know.
question...
[my gauge tells me] i was running about 17 psi on my viggen with 3" DP and ETS intercooler (no tune). out of the three springs; soft, medium, hard (all relative of course) what would be my best bet? i know the only way to know for sure is to try them all, but i'm worried its just a crap valve.
got it all sorted out. the lightest spring works the best, got it to run 17 psi like before. decided to run it in "reverse" out of preference... i love how aggressive it sounds that way
you all know what a bpv looks/sounds like, but ill post pics and video tomorrow sometime
well now i think i might have some boost leak. i noticed boost was down about 5 psi at peak. idle is still the same, but it just doesn't have as much umpf as before. i put the stock bosch valve back in, and its not as bad, but i'm still not back to where i was. i'm going to zip tie all the fittings and barbs this weekend and see if i slow it down.
if you are considering buying one of these i wouldn't recommend it until i figure out where my issues are coming from.
3 people have great success, and 1 person doesn't. I think it was your installation, or maybe try a few other things.
