If you look back in Early January of this OP's thread, you can see the dynoplot and the linearity of it.
Note his comments about how things are load related. Mazda's MS computers (in the 3/6) don't work the same way as most other EMS. They work on a model of requested torque. Which means that you setup ideal targets for stuff like boost, but in reality it will do what it can to bring the car back up to its level of R/T, even if that means over running the turbo a touch. In other words, its trying to hit those torque targets as fast as they can. In lower gears the R/T tables are programmed to be progressive due to a lack of traction. But in the last three gears, they are linearized to try and make maximum torque, all the time.
By post mortum, if the pistons confirm what he'd been monitoring (a complete lack of knock correction), then I know its not going to be excess cylinder pressure spiking due to too much timing, much less blatant detonation (which will pound out bearings and break ring lands), or pre ignition due to a drop of fuel pressure (which would result in holes being punched through the top of the pistons). But, it would show that the rods simply can't handle that type of torque, and they physically fatigue.
It still strikes me as odd, because the other few dozen people haven't exhibited a failure, and I've done tons of research on what others have "pushed" on the platform, and 300lb/ft of torque isn't anything big.
So (again, in black and white), either there are some monumentally lucky people out there, or this is a fluke, or something ELSE is wrong.
Frankly, I consider this a much better approach, then "sorry dude, too bad, that sucks!".
But all I ask, with all due respect, is you don't put words in people's mouths or misrepresent the situation. To say it blew up "days" after is an exaggeration by any stretch (tuned early January). Let this pan out, and be objective about it, before passing some judgement. You're welcomed to call me and discuss this if you'd like (847-678-4311), here, or privately. I have nothing to hide, and am an open book.
Its just how I roll, man.
