It takes a good bit longer to install a turbocharger than you’d at first think.

I set up to check out the preload on the wasetgate actuators to ensure they are balanced and set to an appropriate level for the K04’s.

I use the air compressor in conjunction with the regulator for a leak down tester to gradually apply air pressure to the wastegate canisters.  It also allows me to get a fairly accurate reading of the air pressure necessary to start opening the wastegates.  The BorgWarner K04 canisters are loaded to open at approximately 7 psi.

Here they are in motion:
