Hi @nfored,
I’d recommend reading through this thread. In particular:
This is above the pressure we’ve specified, and for a longer time period than we’ve recommended to test for, so isn’t something I can meaningfully comment on the results of (because it’s not the same test).
That said, I’d be a bit concerned about potentially damaging the cables by pulling enough air through them that they start to deform to allow air to flow through more freely. I don’t expect that would meaningfully impact the water-tightness of the vehicle under normal conditions, but it could cause future vacuum tests to fail (which makes them less usable as a safety check), and would likely increase the speed of a leak if a cable got a cut or gash in it while submerged.
