Wow, terrific carnage. Sucks you don't know what happened, and really sucks you didn't get a chance to see what that combination was good for. New combo sounds promising though. Was the lead going to the wastegate melted? It's in a high heat location, figured thats what caused it. Whats the thought process on dealing with possible future boost control issues?

Did you have water/methanol injection on this setup or not Matt? And what fuel were you running when it happened?
I'm just curious how many octane safety nets were in place when the kablammo happened. Seems like potentially an interesting data point.

Matt,
Do you run any sort of air filter?
The coil on the 4 port valve you are using for boost control is tiny, it can't really generate very much force. I wonder if after thousands of street miles without any filter one tiny bit of sand/dust/crap from the intake manifold could make its way into the valve and make the spool sticky, resulting in unreliable boost control?

there are certainly lots of possibilities haha, but boost valve is working fine, i tested it again when i tore it down, ill test it again when its running again.
this 250k mile 6.0 i got as a replacement i tore down, and the top ring gap is 17-20 on nearly all of them, *didnt get them all out yet*
im pretty surprised after 250k that some are that tight!
certainly would cause an issue on 14+psi and strait pump gas in my opninion

Ok, saw the video. Good stuff! I can't wait to see how much punishment this one can take with the rings gapped out appropriately. (and with that big ole' turbo that should blow a lot of air without heating it up quite so much)
