OK so i have got the new turbo on and although i love the dose sound i dont want to reck my new turbo because the compressor surge and it will eventually.so im going to have to go with a blow off valve,and i dont want a jap wanky one that just goes psssshhhtttttt,has any one got one on their car here or can anyone recomend a bov?and idont want to go plumb back,cheers, at the mo il looking at this one itsd a turbosmart race port,http://www.turbosmartonline.com/index.php?id=48 its the top one

Greddy type r!!!! its like an immitation dose.....quite pricey though.....I have one lol......it came on my car when I got it Some original photos have not been recovered yet.

cheep compared to the race port at $425 at staff discount price

where does the pressure from the blow of valve go if its plumbed back, and what is it plumbed back into... still learning lol...

it goes back before the turbo,just after the air filter,and gets reused by the engine,it gets rid or the compressor surge but with no sound, aaron are you sure your soung is not just compressor surge??

you wont wreck the turbo at all.... why dont you want to plumb back? if you really want one, use a std bosch one (or 2) and plumb them back. but its just a complete waste of time and money!

just because i dont want to run pipes to plumb back because im probly goung to run the filter stright off the turbo depends on what i choose and how room i have

no afm i would assume?the bigger the opening the quiter the psst

ok i found a video of the Greddy Type-R BOV my brother was talking about, its like an immitation dose sound but a bov sounds mint to me, my mate had 1 on his mitsi and low boost it would dose and hight boost its sorta like half dose if u understand my language. http://www.youtube.com/watch?v=P4Xdmk7qsGo http://www.youtube.com/watch?v=fzBgO...eature=related (http://www.youtube.com/watch?v=fzBgOL7RtSM&feature=related) (same car and bov but camera on side of car to make it sound better) this is a bov i used to have on my laser b4 i changd it to a dose pipe the tial 50mm bov, very good but i changed cause wanted dose lol http://www.youtube.com/watch?v=NQAcVgKPXG4

the tail bov on the suby still sounds like compressor surge,you can hear the bov just opening and it sounds the same as the other one

i love the 1 on the supra Some original photos have not been recovered yet.

My favourite BOV is the one on the culture shock 67 camaro.......but I dont know what sort it is....I think it sounds coooooool especially in the 2nd video at the track http://www.youtube.com/watch?v=tmPe9...eature=related (http://www.youtube.com/watch?v=tmPe9IOTywc&feature=related) http://www.youtube.com/watch?v=YP0jm_36qdA

are GFB bov's any good? how do they compare to turbosmart? there prices are only slightly cheaper than Turbosmart (ie they're not like those $100 imitation ones) so I would assume they would be ok, thats my guess tho.

their good,yeah aaron i want to know what that one is aswell men,i love it

couple of questions as I'm a bit stuck, I've read that using a atmospheric-venting BOV in conjunction with an AFM causes overfuelling (as the ecu calculates how much fuel to put in for that pressurized air from the turbo, but then that air is let out via the BOV but ecu still puts that amount of fuel in, so it briefly runs a lot richer), and also it can cause the revs to drop below idle when closing the throttle, and sometimes it will stall. Apparently that can be prevented by using a plumb-back BOV, but I really want to be able to hear the BOV. So I'm wondering, would it help if I put the AFM directly before the throttle body, and the BOV before the AFM? would that work fine? I just dont want to go and buy a BOV and then find out I cant use it because it's the wrong type and will cause problems. Oh yea and I plan to run Nistune so AFM is my only choice... cheers Sam

if u put ur afm in the cooler piping it all work fine no matter where u put the bov

Quote: Originally Posted by patch if u put ur afm in the cooler piping it all work fine no matter where u put the bov thats not quite right,what boost you want to run up to? if its too high you will leak boost out the afm,what size piping you got what size injectors?

Quote: Originally Posted by NZ VL com thats not quite right,what boost you want to run up to? if its too high you will leak boost out the afm,what size piping you got what size injectors? i'll be using 2.5" piping (havent got it yet, still gathering up bits for the conversion), and standard injectors for now (until i've saved up a bit to get some better ones). so I'm hoping to squeeze possibly 10psi out of it (more if safely possible). and then when (if!) i get bigger injectors crank it up to 15 or so. (possbily in conjunction with a z32 AFM). cheers
