You can check for carbon buildup without taking off the supercharger
Carbon buildup is inevitable and I’d like to check how bad it is so I can bundle it with other work that takes off the supercharger, but I don’t wanna remove the damn thing just to check. All the videos I found remove it.
But I just did a check without removing the supercharger. Only had to remove 4 torx screws and wiggle the boost pressure sensor out (circled red, 1st pic).
Stick a boroscope in there and you can see the top of the intake valve.
