I was up way too late one night and came up with this a few years ago....I have seen these also used in the automotive world.....
It has helped me many times when trying to figure things out on one of my turbo sleds.
I am sorry about the terrible video.. I took it with my phone and it was meant for my buddies so I am messing around in it...
I hope you are able to get the just of what this system is and how it works..
It is very easy to build on your own (no rocket science here) and works great... I do this test on my sled every couple rides just to make sure she is tight...
Here is the Video:

(may have to copy and paste link in address bar to get this to work)
As you can see in the Video I test for leaks by filling up my sled with air pressure from an airline and compressor. I usually put as much pressure in the sled as boost I am running.. I also kink the line going to my fuel controller just to make sure I do not damage the internals or boost sensor at all during this test.. So if I am testing a pumpgas sled i will fill it up to 8 lbs air pressure or so....
If you find leaks in your donuts do not be too alarmed because most of the time they will seal as the sled heats up and these expand and close off.... If they are major leaks then replace the donuts.....
It really is amazing the things I have found and how air tight I have been able to keep my sleds by using this periodically.
I promise you will find boost/air leaks places you would of never thought...
The other thing that is interesting to me is that some of the boost leaks do not show themselves until a certain air pressure.. For example in the video I hit 7lbs of air pressure before the air leak on the coupler by the turbo started to leak and it was like opening the flood gates from 7 pds up... Leaked big time...
After I fixed this air leak I rode the sled the next day... I was boosting 2.5 pds above what I had been the previous ride. That tells me this boost leak was costing me 2.5pds of boost and making my turbo work much harder than it needed to....
Boost is for Heros!!!!!!!
Good luck to all you Turbo Heads out there!!!!!!
