Boost Leak Test

Anyone on here done a boost leak test?

I do not yet have a tester but I can see that it shouldn't be that difficult to buy or make one. Appreciating the need to have it very well clamped in place to avoid it flying off during pressure test.

It's the procedure I am concerned about. Not everyone seems to be suggesting the same technique.

One quite good explanation of two alternative methods is here

My preference here is for Boost leak test installation 1. The only downside being that you would be pressure testing the part of the induction system prior to the turbo which in normal use will only see vacuum. Big advantages being; easy to get at and you do not have to disturb the boost pipes in the process of doing the test.

Boost leak test installation 2 effectively puts the leak tester in place of the turbo. So only tests the boost pipes but disturbs them in the process, is difficult to get at in my car and can never fully test the turbo outlet to boost pipe connection (it having been disturbed to do the test)

Any thoughts on these or any alternative methods appreciated.
