Oh, horseshoe! Lucky or what? Still, … that oil back up to an inlet air filter: … mystery?
F.S.
There are lots of reasons for cylinder #7 to misfire, throw a code. In your case, however, … most likely it narrows down to: … you have - by now - burned or broken valves. Perhaps even a hole in the piston? Serious stuff. Cylinder # 7 overheated and things went worst in the process.
First thing I would do is not start the car again, … than borescope the cylinder # 7 to see the damage. View won’t be pretty, …

I'm thinking you have internal damage to your motor, likely needing a rebuild or replacement. Did you beef up the internals before supercharging it?
Boroscope #7 but I don't have good feelings about a positive outcome for that engine.
