what did you do? boost leak test
Read a bit. Basically plug the supercharger inlet and hit brake booster hose with the compressor.
Miss anything? Easier way? What did you use? Procedure? Thanks!

This is what I did/do on my TT car, and could be applied to a SC application.
I bought 2 rubber caps from Lowe's and threaded and sealed a Male air chuck into one of them. I can hook my cylinder leakdown tester to that fitting and then my air compressor to the leakdown tester. This just basically acts as a regulator where I can see how much air I'm pushing through the system.
When I had a boost leak, I could make about 9 psi, so I knew I needed to get to or above that value for it to show itself to me. Sure enough, crank it up and I hear some air whistling out.

I've never tried it but if you run out of ideas you could wrap each joint with Saran Wrap or a stronger palstic.Take the car out and get into boost.You should see were the wrap is disturbed or split were the leak is.If you have a rough idea of where the leak is you could also put some slicone over the leak area and again get into boost and look to see where the slicone is split.
Good luck.

Usually common sense and a visual check will spot any potential leaks. It isnt difficult to ensure with a quick inspection that all pipes and hoses are sound, and that all flexible couplers and clamps are installed correctly and in good order.
If you are going to pump air into the system for an actual test. You'll need to ensure both ends of the system you wish to test are fully sealed up. Then pressurise to normal working pressure, or perhaps a little more. You will likely need a compressor for this and some sort of regulator for the supply

I sent you the pictures and how I made my set-up - worked flawlessly for me!
Thanks,Matt
