Gmctd, I am not trying to stir a debate with you, so please don't take my disagreement with you wrong. You referenced the air compressed tank comparison, that's why I used it. In my opinion, that comparison is not relevant at all in this conversation. Regardless of engine displacement which is also irrelevant in this example, pressure is pressure. Plus, pressure is generated by the turbo, if lets say the snubber will be pushed out by an unfortunate event (and will be pushed upwards, since that's how it's mounted not towards engine compartment), an under boost code will immediately be triggered, it will be a pressure bleed through about a 3/8 hole, right? How much pressure that turbo can hold when there is a bleed through that 3/8 hole? I doubt will be more than few psi, that if the limp mode is not triggered (don't recall if under boost will trigger a limp or not). I know, I don't have any measurements or scientific data to back up what I say (and neither do you, considering the above conditions - i.e. how much the pressure will still be in the intake with a 3/8 hole in it), I'm just using my common sense based on my "enthusiast" mechanic experience. I can hold 25 psi with my bare hands, it's really not a lot of force. I am 100% sure that my snubber won't ever be pushed out, even if I double the pressure. I have a little over 10k since I installed it, I hit few times 23-ish psi of boost, it's still firmly placed as it was before. The 1/8 npt is a relatively fine thread, there are easy 3-4 threads in the "thin" aluminum wall, plus the torquing force. It would take way more than 25 psi of pressure to strip those threads and push that snubber out.
Now, regarding where you recommend the location for the boost, is it a "safer" place? Maybe, and only because there are more threads, but again, I don't think this matters on the modest 25 psi of pressure. [edit] The main reason I chose that location is the convenience of not making a mess with drilling in the valve that corresponds to the intake. Also, I am not trying to convince anybody to follow my example, this is how I did it, it is a proven solution, who doesn't want to follow my example, that's their choice. At the end, the owner has to be happy with the choice he makes. [end edit]
In the below pic (an "experiment" I've toyed with a while ago), the valve is mounted in plastic, it's about the thickness of the valve cover, no epoxy, nothing but the valve threaded in plastic with plumber tape. That cylinder holds 60 psi of pressure without issues. I am really not worried a bit about the "thin" aluminum wall not holding my modest 25 psi of pressure.
If you want, let me know, I'll snap a pic with a pressure gauge to show you
