So when testing for leaks what pressure to go to and how long should it hold steady at that pressure, thanks in advance

So when testing for leaks what pressure to go to and how long should it hold steady at that pressure, thanks in advance

I have previously suggested: "Testing for boost leaks involves introducing controlled pressure, i.e. 10 to 15 psi (0.7 to 1.1 Bar) from an air compressor into a non-running engine, with a pressure testing bung, such as shown in the diagram below and various other hoses plugged off (as appropriate to that test). "

I doubt that even a real tight system would hold steady for very long (depends on which of the testing options you use). I think the main issue is how fast it drops and whether you can find the leak with soapy water while the pressure drops (if not, pump it up again).
