Track Tested: MK8 Basic vs Full Retrofit w/ Crankcase Data Logging
Visualizing what is going on in the above video should really help illustrate what’s going on dynamically. The prior 2nd and 3rd gear pulls for “standardized” testing were just that… standardized tests to control variables. Seeing what is actually happening on track is really neat, and there was even one instance where I think we captured the oil sloshing phenomenon, noted at the 5:56 mark.
I did forget to reiterate it at the end, but to be clear: There was ZERO oil consumption over the entire rest of the weekend in full retrofit form. There was 230 track miles put on the car total, less than 30 of which were in basic retrofit form - where 1/2 quart of oil consumption occurred in only 6 full laps.

NOTE: If you have a turbo that does NOT use a turbo muffler adapter or one that does NOT use a stock size charge pipe, you will need to tap for pressure somewhere between the turbo OUTLET and the THROTTLE BODY. Some charge pipes may have a 1/8npt fitting intended for water/meth injection, or you can possibly use:

Have a bung welded to your charge pipe if it is aluminum
If your charge pipe is thick enough, just plain tapping for a 1/8npt fitting (and using some sealant) should work as well. Verify it's not leaking!
