Some progress. Alex and I spent a few days on and off making this thing. Finished it last night.

It's made from two Stromberg float bowl covers. Broken down:

The top of the upper cover has been turned down and threaded:

The inside has also been turned down to hold a spring:

Bottom cover has been mostly hacked apart and also has some slits along the perimeter (I love the indexing table):

The tube has a snap ring that places it flush with the face of the bottom cover:

Rubber membrane with a spring perch/50mm disc:

Tube goes inside the bottom cover, membrane goes on top:

Then with the spring on the membrane's perch followed by the top cover and the threaded bushing, you end up with this:

Weld the tube to your charge pipe and run a vac signal to the threaded bushing and you've got yourself a blow off valve.

looks good...I am so glad you said what it was, 'cause I kept looking at the progress pictures and couldn't tell you at 1st where the heck that thing was supposed to go !!!
(turbo ignorant :) )
 
Made a tentative start on the next little side project today. This is a scale 1:2 foam mockup/prototype, but you get the idea:

Since the small CNC in the shop doesn't have a tool changer (and I can't be bothered to re-zero the ****ing thing every time I swap tools) it doesn't have any of the mounting holes, fillets, or chamfers. It was just as well, since I have to change some of the dimensions and setups now anyway.

This is the cad model in its current state, and is pretty representative of the final product:
