Testing your intake for leaks.

The way I do it, I block off the intake at the air cleaner and the exhaust right behind the turbo. No air can escape the engine at all (with the exception of any leaks that need to be fixed somewhere), and no air is flowing at any rate. It is simply building a pressure in the engine and systems. turbo never moves.
