      I got a few pm about what else is needed to make my modified valve work on the TT.
      All that is needed is (2) 1" to 1 1/4 couplings, a piece of 1 1/4" hose and hoses clamps.

      This is a picture of omerkm1 valve that's going out today minus the hose(busy at work and didn't get to cut it yet)

      Madmax DV is installed and the performance is amazing. The car hits boost quick but also holds it better and less drop between shifts. I would recommend this to anyone that can talk Max into building one for.

      FYI - I am coming from a Forge 007 DV

      I'm glad you like it

      This thing really rocks, we had tested on an evoX before I sent it to you. The car picked up 4 psi of boost and hit over 320 load from a previous best of 280. We even had to rescale the ecu since mitsu had it only scaled to 320, simply amazing for just a BOV.

      Omer, can you post a picture of the valve mounted. I'd like to see it on car without a dv relocation(if you don't have one). Thanks

      If you have to have one the aftermarket valves, the Synapse synchronic bov is the one to have nowadays.

      It can be recirculated or vented to the atmosphere and be used in both pull or push orientation. Supposedly it's really fast and can hold BT pressure.

      However, you can always go the madmax way, and have the same performance for a fraction of the cost.

      I'm not Omer but I did take some snap of My install. I,m installing a High flow manifold shortly, so I may do a more "clean" install afterward

      Cool, thanks!

      I have afew questions?
      Did you get everything sorted out?
      How do like the Madmax valve in comparison to what you had before?

      Not that I have any facts to back it up, but I do enjoy my APR R1. It is just low profile, no springs to mess with. Kind of like a great upgrade from the OEM DV and guaranteed for life. I had a Forge 007 and messing with the springs was always a pain. And I was constantly relubing the piston with Mobil 1 syn grease. I just like the APR because its so easy and maintenance free.

      Feels like it responds faster than the Forge did, but again only butt dyno data

      Yeah, I did sort everything out, it has been a PITA tough to make everything fit as the valve needs to be placed opposite to a regular valve (boost on the bottom) and the overall, especially with the fittings makes the whole thing a lot bigger than a regular valve.

      I'll say that the boost awnser is incredible compared to the forge valve I had before, you're right when you say pistons valves are lazy. The only thing I was afraid of was the "swoosh swoosh swoosh" sound i was hearing that reminded me of a BOV I had on a previous car that was set too stiff and destroyed the turbo by sending back pressure to it. Other than that, this valve is awesomeness!!! I might develop one designed forr our cars that won't need all the fittings and will fit straight there

      The APR R1 works well, but personnaly, after I had to send him back the 3rd time for a defect, I quitted, Damn I had to buy a 710n to put one the car waiting for APR to redo the valve under warranty. Yeas there's a lifetime waranty on it, but hell, I had it on my car less time than it was being repaired....

      Good to hear it is working as intented.

      The rapid "swoosh swoosh swoosh" sound you are describing (we went trough this via PM but I'm posting the info so everyone knows) is typical of all diaphragm based valve. The reason you hear it more than a Bosh 710 is because this valve recirculate a lot more volume and is metallic. Plastic valves tend to be quieter but are not as heavy duty as their metallic counterparts.

      As far as making the valve plug and play and fit better, I have all the required parts needed but the DIY guys like you have to come up with your own solutions.

      Any diaphragm valve(low mass) is going to respond faster than the piston types(heavy mass).

      The problem with the aftermarket diaphragm valves designed for the 1.8t is:

      1) They are not built for higher boost applications, anything over 15 psi they can not hold properly(soft springs)

      2) They start to leak at early pressure(7-10 psi). Kind of like a wastegate, at a certain psi, they partially crack open, forcing the turbo to work extra hard to reach it's targeted boost(creating heat).

      For a "stockish" car they are just fine, but the minute you get a tune they are weak at best .

      I mean build a valve from that design that would fit right there without adapters

      I'll check what i can do and if the cost would be low enough to be a good solution

      Max - Sorry I havent posted pics, but in refreshing the suspension it seems like everything the shop took apart, subsequently broke and had to be replaced.

      The DV kit Max sent me went in very easily. All the fittings and down sizing pieces were perfect and I would highly recommend anyone buying a DSM valve and sending it to Max for retrofit.

      I will post pics as soon as I can.

      You don't know, and like most, probably assume the poor performance is the norm.

      You'd have to test it, like I did (test for both spring holding pressure and recovery speed, especially at high psi)
      Or you can try a madmax valve and realize how much your previous valve was sucking at life .

      I am taking full credit for the "Madmax Valve" moniker.

      yes, those could all be symptoms of a DV issue. They could also be explained by a boost leak though. What kind of DV are you using now?
