did it just melt there, or did the turbo get some stuff through it as well?
it looks like where it burnt though you should be ok, as in its not as bad as it could have been

did your logs show detonation, looks like the chamber on the head is spotted.

Just saw the nice pics. Ouch. Gonna have to go to Jim's after work tonight and witness the damage firsthand!
Unless there was an issue with the power or the connector at the injector, if the injector stopped firing I'd expect the other 3 injectors on that bank to do the same...
It was a cold day, but humid. Still good for making power. I wonder if we didn't lose some water/meth pressure? AFRs weren't super great but again not all that bad, unless we missed something.

looks familiar. i was able to get my cyl head re welded for like 40 bux at a local shop, my block didnt look as bad, but right around the cyl looks good on yours, and i wouldnt be surprised if it sealed fine (mine did)
i was on a 20 psi pull on pump and meth, 144.6mph when it bit me. i was happy it was a relatively cheap and easy repair.

i am sure it was a combo of not quite enough fuel and not good enough fuel. no one to blame here but me.
