The lack of miles and the cooler air requiring more fuel leads me to believe you may have not ever had an adequate supply for this setup. Prochargers have a sharp power curve that has a very slim peak. They don’t draw as much fuel early on or even through the mid range. It could very well be that insufficient fueling wasn’t discovered on your tuning day. It’s all speculation though. Really everyone of us could be wrong and I’m fully onboard with the others notations about using bigger injectors or secondary supplemental injectors as a safer alternative for a powerful build like this.

Let me help you understand.

If it was not a distribution issue all 8 would have failed not just 1.

The fact that 1 cylinder failed is direct evidence of a distribution issue.

Just because a lot of people are doing something wrong doesn't make it right.

IMO, the manifold is designed to be dry flow. Try to make it a wet flow and you will get fuel separation/fall out/distribution issues.

Thanks for all the input from everyone, and, that's done, so my biggest concern is not to do this again, going secondary port injection, back off the meth, go full E85, and try again, did I mention that was on ms109 too?

And it wasn't even that much of a hit, like a 40-140 and 4 gears, zero warning, no popping or banging out, just a horrible smell and a little (wife says alot) sideways, maybe 6/7 seconds and that was the end if it, no front main, instantly filled the catch can, blew the vacuum hoses off oil soaked and smoke everywhere, but we didn't even get close to the guardrail(s)

The way to go is definitely port injection.

Jannetty just gave all of you the answer, pay attention.

It could be a distribution issue. I would like to the what the wideband said at the end of that run.

I have seen(and done) lots of stupid things. Ran myself out of meth. Raced with low fuel and am aux pump, ran out of fuel system due to colder weather... there are lots of ways to run out of fuel. If your tuned perfectly and it gets colder the meth kit won’t know to flow more fuel. The stock ecm will but it may not be enough.

If you want to run 20psi you should just step up to port and e85.

Yep, I plan on 20 to 25 pounds on kill mode and went with port injection.

LOL just like when you lose an item, and are running around like a chicken with the head cut off looking for it and it is sitting right in front of you.

how much meth were you spraying?

the log file would be greatly beneficial to this..... I would like to see it and am curious about more details about your setup.

[parish8]

I don’t think a melted 7 piston necessarily points toward a distribution issue. If your lean across the board(without meth) #7 is likely the first to go. He could be lean across the board for some reason.

I am curious if there is some amount of single nozzle meth you can spray that gets so evaporated it does distribute well. Like 100hp worth in 1000+ hp worth of hot air. Maybe egt’s would help show this.

I could see that on a SBE but with a forged piston that is normally more tolerant I would think you would have to be excessively lean on that cylinder for it to let go under the conditions the car was operated. It's not like it was a mile long pull. Something would have to be way off to melt a forged slug that fast on a little test hit no?

If I knew how to post the log I will, I email them to my tuner, know how to do that, ideas?

Could upload it to Google Drive and share the link.
