Today I disassembled my Audrey with the intent to install pre-infusion mod and to clean the group head. I did not install the mod though. I realized that my mental picture of the mod is not matching what I found in the machine.
I am looking for a place to attach the water shock absorber. I have a couple of ideas now. I can connect the shock absorber right at the high pressure nozzle of the pump. It would give me an opportunity to connect a pressure gauge. That would force me to replace or modify the high pressure tube, which, to my surprise, is made out of heavy plastic. The plastic holds 15 bar pressure. Impressive! Another possibility is to attach it to the input of the OPV valve. It is a less attractive option because of the lack of space around that area.
The second option is an Allen screw that looks like a screw on the E61 head. It might be there for the same reason too. If it it the case, then I should be able to use it either for a water temperature gauge mod, or use it for the pressure gauge and shock absorber.
I also disassembled the shower head and discovered that it is a bit different. I think it is a simpler design than on the Silvia.It might be less efficient as well. I have not way test that. I do not have a SIlvia.
I am posting a few pictures of the Audrey head here.

The difference between the Silvia and Audrey is visible on the following picture. On the Silvia, the shower head has a removable disk below the shower screen. On the Audrey, the disk is not removable. The small black dot on the right of the deep part of the head is the water orifice.

Finally, a little bonus for phone junkies like me. I used the Audrey water container as a light modifier for taking the pictures above. I am using a Nikon SB 28 with a PocketWizard Plus II, You can see the flash at the top of the picture and the Wizard in the left bottom corner.
