Cylinder 3:
For comparison, cylinder 1:
Cylinder 2 doesn't look great, but 3 is the worst by a long, long shot. One and four are picture perfect. Live and learn, I suppose. Really didn't expect to have detonation issues with 100 octane and water injection on an 8.5:1 motor, but anything seems to be possible.
Head appears to be salvageable. Probably will replace the rods on principle, since it's clear they were hammered pretty hard. Pistons are obviously toast. Hopefully the turbo survived. About 90% sure the block is trashed, cylinder 3 has one very serious dent in it that I believe is terminal. New block, new pistons/rods, keep my oil pump and auxiliaries, refresh the '99 head, throw it all back together, and try again.

Nice dent you got there. Kinda funny it's #3. My intake valves in #3 are burned due to overheating CLT early in the year. Is #3 the one running hot with rerouted blocks? If so, #3 is the new #4...?
Bad to hear, but detonation can kill any engine in no time at all as we all know. Good to know it's not starvation, got me worried a little. I already found myself on AccuSump's homepage this morning.
Were your AFRs spot on on the track? Did you use detcans while tuning? What kind? Are you running a knocksensor that pulls timing? I've got some headphones to my knocksensems that I use during tuning, but no active pulling in MSPNP.

Are you guys just tuning way to close to the ragged edge? Are you using WI to squeeze that little bit extra out, or is it a fail safe? Maybe #3 isn't getting much love from the WI?
Sorry to hear it :( This experience will probably lead to Hustler contemplating selling his car and buying an EVO or something.

hahahah. you are right abuot Hustler. He probably doesn't want to look at his car now.
I will be very open - our engine loss was due to a careless tune. We had less than 48 hours to get everything together before the car went to willow springs. we had a "good enough" tune that was obviously not good enough. (maybe combine that with a block that had tollerances that were probably a little too loose.) WI for me is being used to control intake temps. there is some extra timing to be gained from it, but my system also has a map cut that if water stops working, it converts to a more retarded map.

negative...I'm passionately in love with my car right now. I'm going to leave it at 11psi though, and take a peek at the pistons and see if I need to pull any spark angle. Its fast enough for now and tracking it for years is more attractive than a few less tenths.

What is the possibility that the high G's caused starvation to the WI system?

it does compensate for a clogged injector (I've actually had one of those). There is a flow monitor inline 2 inches from the injector. If flow stops, it reverts the ecu map to the one without water.
I'm not sure what Andrew is running, but I run a snow performance kit that has a good reputation for failsafes in meth communities.
