Put my Bailey dump valves in

[Yessss4]

model DV30

they go in easily. i got them from bailey (England), but you can get them trhough AWE now i think. if anyone wants installation pointer, just ask.

I originally put them in with the bottom of the valve towards the recirc, like the stock Bosche valves. But the stock valves are in that way because they might not handle boost and cause boost loss. So i flipped them around.

The Baileys are designed to put the bottom of the valve (the part that opens) towards the boost, and the exhaust side port to the recirc. Bailey states that the valves are completely vacuum operated, so no worry that excess boost will now have a harder time opening the piston-based Bailey valve vs the Bosch rubber diphragm valve. there is better air flow through the valve this way also.

I wish I had some server space to post a picture, but i use netzero and dont have any.

can i email anyone the picture to post?

They look great and no problems. instant spooling between shifts.

That way we might actually be able to determine if the actual boost pressure tracked the desired boost more closely.

These sound cool. I'd also like to see what VAG says about boost with the dump valves. Thanks for your effort - love to see pics.

I want to see...
did you recirculate the air... or did you let it just blow off...??

how does it sound??

email me to get on the contact list all will be forwarded to AWE!!!i felt it was the best and easiest way to have a known reputable tuner get involved-for billing and shipping purchases!!!!valves are enroute from england-if you want in on the group purchase its not too late another order will be made soon!!!!

the "PFFFFFT" is being sent back into the turbo air intake.

The 90 degree vacuum BSP fitting elbow connector comes pointed in the direction of the exhaust port (AWAY from the car's vacuum T connector)> I checked with Bailey about unscrewing the connector (about 235 degrees on the passenger side, and 180 on the driver side). They said it shouldnt be a problem. Those connectors screw in and they get tight long before burying the thread all they way in. What I did is get a grommet, split it into 2 circles, and put that on the connectors, then screwed them in. The grommet halves tapered onto the valve perfectly, and gave me that extra seal protection (at least in my mind). I used 1/8" vacuum hose (thick-walled; Pep Boys had the best!) and Porsche clamps (the gold crimp clamps) on the vacuum lines.

As far as installation, you first have to remove your Bosche valves.
First, remove the vacuum lines. Careful- you have those same junky little crimp-clamps as on the TBB sensor, but now they are smaller and harder to pry off. I actually busted a vacuum connector off of the Bosche while doing this. ANother approach is to just cut the vacuum lines right before the Bosche, being that you wont use them anyway. BE CAREFUL not to cause too much push-pull action on the vacuum T connector nor the thick hose going from the T to the metal vacuum lines , or else you will be replacing them also!

Next, under the Bosche, I disconnected the short right angle boost hose FROM the intercooler pipe. Its easier to slip it off of the intercooler pipe in this tight area than to fight to try to get it off the bottom of the Bosche (or onto the bailey)
.Next, disconnect the recirc hose from the Bosche (the hose going from the silver air intake pipes to the Bosches).

So, you should have the 2 Bosche valves with a short curved hose out the bottom. Undo those clamps and remove carefully that hose from the bottom of the Bosches and set them aside.

You can prepare the vacuum connectors on the baileys as I did, or put them in the way they come (this will leave the vacumm connectors pointing away from the T connector , and you will have to do 180 degree turn with your vacuum lines (CAREFUL with kinking and collapsing under vacuum!) Thats why I like what I did with poiting the bailey's vacuum connector towards The vacuum T connector on the car.

Next , hold the bailey in the car where it will be placed, orienting the bottom connector down, and the side port towards the sides of the car (towards the rubber hose coming off the silver air intake pipe). Visualize how you will oreint the short boost hose so it will pop right onto the angles intercooler connector, and enf up pointing the side port on the bailey in the correct direction. Next, put a little water on your finger and rub it over the connector on the bottom of the bailey valves and slip on the short boost hose you removed. Check placement again quickly because its a pain to try to twist those rubber hoses on the metal baileys once the water dries! Put a hose clamp onto the boost hose and clmap it to the valve. Put another clmap on the boost hose (dont tihgten). Place the valve in the car holding it in one hand with a finger preventing that loose clamp from fallin off. With the other hand, wet the connector on the intercooler pipe a little and pop the boost hose from the bailey right on. Tighten the clamp.

Next, make sure you have a very loose clamp on the recirc hose thats coming off the silver air intake pipe. Wet the side connector on the bailey a little and pop onto that hose. Tighten the clamp.

next, do your vacuum lines. I used neat looking Porsche clamps. You can use regular screw clamps also (the Audi-Porsche dealer has both- you decide). BTW, those little crimp clamps that were on the stock vacuum lines- the audi parts guy states they were replaced with screw clamps (the good kind that has rolled edges as to not bite into the hose).

and thats it! I dont hear any sound when driving because these are RECIRCULATING valves (as were the stock Bosche vavlves- the excess boost is dumped into the air intakes lines- not to the engine compartment.
any questions, or if i misstated a step, let me know.

i just have piece of mind knowing that these are less likely to fail than the stock valves (they look good in my silver car also).

Bailey does make colored valves, but dont know if they have colored valves in the recirc model (DV30) yet. you can check with AWE or bailey ( www.baileymotorsport.co.uk ) to see. they DO show yellow on the other model valves, so there is hope for you Imola owners- but remember- these things are hidden under the Biturbo cover , so you wont see them anyway!]

Venting BOV air messes up the air/fuel mixture so it's typically not done on the street. My HKS BOV recirculated like the stock one and it made a nice WHHOOOOSHH sound. Actually the stock one isn't too quiet either once you get the K&N cone filter. Nothing like shifting at WOT when passing a convertible on the freeway. Always turns heads :-)
