hi guys i want to fit some of these. but dont know which ones to go for. ie the one that fit where the reserc valves are atm or wether to fit them in the turbo hard pipes iam long at a set of jdmprf. blow off valves that look like they fit in the stock position. they are asking £100 for the pair. what do you guys think.

any input would be greatlly appricated.

I've got twin Bailey dv26 dump valves fitted to my car and are located where the original recirculating dump valve's used to be but for some reason they are quite does any one have an answer why? Or know how to make them a little bit louder.

I'm guessing they just seem quiet to you because of where they are mate. People outside the car and mainly in front, probably think they're fairly loud.

Compare to my Rs turbo they are very quite and I have two as well which is strange

Where were they situated though?

Ive got some and sound cool .si dont know jack

si dont know jack

 

So are you telling me that they add performance and responsiveness? I know more than you it would seem! :rofl:

 

The ONLY 'blow off valve' worth having is one's own anus! :wack: :lol: :rofl:

Seconded

HKS SSQV in recirc configuration is probably the best solution from a performance point of view if you must have them. I personally prefer none at all.

ok so what benifit will i get if i get a set of these.

No goosehonk. I believe the sprig is stronger which would make them more like newer recircs. I'm sure someone else will have a better explanation but these are very popular

Are you running no recircs or bovs Noel?

i would like to know a bit more before i make any decisions.

Pretty much :D

Might be worth making a thread about them. I know quite a few pete have them

I have the GHK fitted and it works fine.

thank you andrew g think that me sorted then. would like to say thank you all for the advice.

Noz do you not find it slower on faster shifting? My swb had nothing sounded nice, seemed to bog down, now with hks bovs, ( couldn't find my recircs...) it's actually quicker.. Well in my opinion, would have been just as quick with recircs.

Where were they situated though?

 

Hi, they are at the front underneath the front nose panel, I know the dump valves are in full working order as I tried both of them on my rs turbo and its a louder sound effect compare to the zed

Question. What psi do your rs turbo and zed run at? Just thinking how the noise increases with the amount I'm boosting on mine, so if you were trying to vent more higher pressure air through one single bov it's going to be louder than two at a lower pressure. Possibly.

My reply would be similar to Stephens. I'm guessing the rs boosts sooner too so if you're testing them you'll probably here more from the rs then the zed

My Rs turbo was running from standard 7psi to 14psi now but even when my Rs turbo was running standard boast it was still fairly loud and sounds so much better than the zed, my zed is set at 12psi with boost jets which was done by Jeff at Zedworld

Try running a single BOV on the Zed and see if that sounds the same.

Hi Noz, That's a good point that's worth trying how would I blank the other one off?
