[QUOTE="TClark22, post: 15514874, member: 48625"] This is a weakness of the stock coyote block from 11-14. 15+ seem to be holding much more power without breaking. But there were multiple factors that make it hard to tell what happened exactly. The car was on 91 octane...could have been bad gas. Could have made too much boost...not sure but all test pulls prior held fine at 10-11psi. Could have detonated...never had a problem with detonation on all the pulls i did prior to it blowing. One of the main reasons (i think) is that my thrust bearing was worn the f out and either fell out of place or had already fallen out of place causing lots of crank movement front to back. The spark plug for that cylinder had broken its ceramic core and sent that shit through my motor scoring up all my pistons...it actually looks like something (like the ceramic pieces) got lodged between piston skirt and cylinder wall, creating a pressure point which blew out the water jacket like that.
