[QUOTE="NTXRockr, post: 13638206, member: 143742"] I've put at least 20 bottles through it, car ran great until that night. Tuned by xxx performance here locally. Tune was pretty spot on, ran 11.8 wot on bottle and 12.5 on motor every time and never knocked or pinged so much as once. Timing was initially pulled 4* for the 100 and 6* for the 150, but on the dyno we adjusted it a little more and it ran great. Not sure on the final timing numbers though, it's been a few months. We won't know for sure what killed it until its torn apart, but the tune is low on my list of culprits at the moment. I've heard the wrist pins on the early coyotes were known to fail prematurely and usually when coming out of power (guess its due to reverse of forces from combustion down to slinging it back up?), and my car was a December 2010 build so its possible. Only visible damage was in the top of the valley near the base of the cylinder wall where the rod popped up and just cracked the block enough to lose oil pressure. It still runs (terrible sounding with the clacking rod lol) and I drove it onto and off the trailer. I'll know more soon enough, interested to see what failed. [/QUOTE]
