Hi guys.

As the title suggests, I'm after a new blow off valve to go with very soon to be completed mods. Just wondering what you all think is a good one to get. I see 'turbosmart' and 'gfb' getting a few mentions but I still don't know what sort to go with. I'm after one that is quiet and will preferably fit under the engine cover with little to no cutting.

Thanks in advance. I appreciate your help.

Gfb one fits under the engine cover without any modifications, can also be set to run 100% recirc

If you don't want to cut your engine cover the Turbosmart Kompact is your best bet.

This one.

I can also confirm the respons fits

Thanks for the help guys.
Does anyone know where i can look at gfb valves? I've tried to google their site and it just shuts down my window......

Heres a link with a some info on the one i bought, GFB respons t9001 ( note: i did not buy it through these guys i just pasted this link to give you some info on it as there seems to be an issue with the GFB website )

i dont know to much about BVs but when you say 100% recirc obviously your referring to where the pressure is going to...

but when a BV is 100% recirc would the noise be somewhat similar to the stock BV??


*EDIT* sorry to hijack your post sort of

No.
Aftermarket BOV's generally flow much more air and faster than stock ones so you get much more sound.

I had a GFB Mach1 on my legacy, fully plumbed back and it was LOUD.
but having a nice big free-flowing intake and a big pod filter also helps amplify the noise. but it's legal

then is it possible to get an aftermarket BV and have it quiet?? i dont really like the whole noise thing, im not even sure ill need one as im only chasing 220KW ATW

Yes you can have quietER ones by having them fully plumbed back, but none of them will be as quiet as the stock BOV.

220 at the treads is pretty serious on 98. I have a turbosmart thing on mine and it isn't too loud, compared to other parts of the car anyhow.

At what power outage do you need to start looking at BVs??

Pretty sure the stock bpv is good up until you start hitting the 300 hp mark?? Someone will free to correct me

quote from MSR's facebook about the plastic BOV's...

scroll down on his page (8 Aug)...very interesting

08 + WRX and GT owners ....Today tuning a 7000km old 2011 wrx chasing what should have gone 200 odd, was struggling to make 185, factory BOV was changed and voom, 20kw more and 2psi, std plastic BOV's are crap and i would suggest upgrading, but DONT fit without tuning to check as everything changes!

Thats why I posted in the first place. Michael at MSR is doing a tune and exhaust and intake for me in 2 weeks and he suggested i get a blow off valve for that very reason.
