hi all, im abit miffed as to where the bov would go, iv seen multiple videos with it placed in various locations, so where is best?
thanks
thanks
anywhere in between the intake mani and the intercooler not the turbo side of the intercooler
Actually thats not correct, it's better to fit it to your hot pipe coming from your turbo to intercooler.
why does no one do that then? i don't think i've ever seen that hmm interesting
Oh really, youv'e never seen a BOV on the hot pipe of an SR.
Just a few

oh cant say i have well haven't recognised it. so why does barely anyone put it there. and whys is better there?
the theory for the cold side is the direction of airflow does not have to change once vented, hot side is something like makes it easier for the turbo to spool again, Not 100% on that. but it comes down to we are not driving around in full blown track cars where every tiny detail to scratch a quarter of a second off a lap time counts, so place it where you like its not really going to make much difference in your life.
Faber-- winding your actuator arm tighter will have more effect on your turbo responce

yea im still trying to work out how to do it, haven't tried too hard yet. Spoonman can you check out my release bearing thread i commented on
when cold, very important otherwise you will burn your wittle fingers, undo the locking nut or nuts if there are two of them on the arm, the turn the female sleeve so that the arm gets tighter then lock it up again, you will have to remove the tiny circlip holding the arm to the turbo exhaust housing slide it off (dont loose the circlip) wind it tighter, just a couple of turns at a time, then put it back on and BOOM, more response.
The closer the BOV is fitted to the turbo the better. After the throttle closes the air will stop flowing causing compressor stall (should you have it all blocked off).
If you have the BOV off the cold pipe (near the battery) like I have, you will find that the air from the throttle body to the BOV dumps out, but the air in the intercooler and hot side piping will still cause compressor stall. Therefore, as Auss15 said, better on the hot pipe.

hey,
the bov should be as close to the trottle body as possible! target is to protect the throttle body,when you go under full trottle of the trottle a huge pressure is bild up and so could damage the valve(and so parts of iron can come loose, and damage the engine)! if fit the BOV here the intercooler remains under pressure but this is also a benefit when you get back on the trottle!:nod: faster response :nod: if the turbo stil stalls, is in my opinion poorly adjusted.
if not correct they fooled me at school and our teacher Sat almost on f1 level engeneering:nod:

Comment retracted.......... was a bit pissed at the time

I was definately under the impression, and from numerous reliable sources, that the blow off valve was there to protect the turbo.hey,

I have been under the same impression also. A throttle body is a lot more sturdy than the internal components of a turbo so in my opinion it's the turbo that needs looking after
Spoonman, sorry I'm from belgium so I do my best :nod:
i also spent more then 2 years for solve this question!
then they explained it to me and I think it makes sense!
the butterfly valve is not as strong as you might think, and it is also very important because it must blok all air passes through. and under very high pressure it is possible that it can not fully close(and i think this is not good for the engine)
Therefore it is also important to have a good BOV to buy, and no cheap imitation and properly tune the bove to the turbo and engine!
My BOV is 10inch from the throttle and have no turbo flutter at all!

Garrett say "Position valve close to the turbo outlet for best performance (if valve can handle high temp)"
I'm not in a position where i am squeezing every drop of performance out of my engine, so the stock placement will do for me.
