Wow lots of detonation, how much timing was in that bugger? 20psi with pump and meth will always be walking that line. Compression, piston/chamber design, and valve events need careful attention to run that type of boost on pump fuel.

18-19 degrees of timing I believe which I think had to do with it. I just cant confirm that being the main cause since it was only the drivers side cylinders that were damaged.

It was stock compression 8.5:1 so boost was definetly safe for 93+meth but I do think it was being pushed timing wise and without knock sensors on 03 cobras your SOL. The PCM pulls timing based on IATs and that has to be set up spot on to save you.
