piston number 1 on the engine was melted completely. we can get some pictures up for it. piston number 4 had a broken ring land, possibly from valve impact but i can't say for sure. it had compression on cylinder 4 so i think the piston must have just broken apart. number 1, DEFINATELY melted though.
However when one only uses 1 gas pump at 1 gass station for every fill, which is denoted on the pump to be 93 octane w/o ANY ethanol additives the variances and unreliability of gas is somewhat (atleast to its fullest extent possible) taken out of the equation. There is 1 gas station in my whole town that does 93, knowing that this would be my gas i would run daily i filled up two 5 gallon jugs and drove my car to Plano on that tank and then filled up with those jugs on the dyno. Tuned on the only gas that sees my tank. And lets say I need to fill up elsewhere for whatever reason (which I have) I just take it easy on the car and don't beat on it. Too easy. Hey like you called it yourself; it's a philosophy yes. But a philosophy I hold dearly, without a proper tune your nothing and no where near full potential of the vehichle in question. My engine failure was without a doubt in my mind caused from overboost and not bad fuel.
BTW some have mentioned it would take a good tune to run my aformentioned AFR's, just wanted to add that my car was on the dyno for 10+ hours for a single pump map.

Ok, ok. Getting off-topic, this thread was intended to post progress of my build and that was the extent of it. No more bickering. I use bad gas my tune sucked horribly and I don't know how to drive. There. It's settled. All bases covered.
Codevo: We are all here to share and learn on what works and what doesn't, hopefully your next build will be trouble free!

Are Evo's known for ringland failures? I thought that was an STi thing. Or is this just purely a high boost AFR issue?

Ha ha I just thought your response was hilarious, not your misfortune. The ringland thing is so pervasive over at nasioc/iwsti that they don't even want to hear about it anymore. Hell they have a registry now.

You say your motor is dead from overboost.
Do you have the overboost logged? Did you see a boost gauge spike to somewhere it shouldn't have been at?
I'm just curious to know why you're blaming "overboost" if you don't have a single piece of evidence that thats what the problem was.
I, like you, have an FP Red on my car. I run a MAX of 25-26psi on the street on 93 octane. I have actually knocked timing out of the car since Connecticut has been brutally hot/muggy lately, causing a few 0.7 Knock (CA) here and there.
29 psi on a FP Red, at 12.5:1 AFR, seems like a recipe for disaster to me. It's really hard to believe a COBB Tuner tuned your car at that level. Do you have a log or dynoplot of this?
FWIW, I made 366/309 on a Mustang Dyno at 25psi with about 12 degrees of max timing.
