cont from my last post...
the primary ring is going to observe the most punishment in a detonation type event. where exactly are the breaking? is it at the top, or between the ring lands? what do the cooling passages look like around the block? ive never had mine apart (or never studied pics close enough) to see what they look like, how big are the cooling passages around the 2 and 4 cylinder? are they smaller or more obstructive the the rest? also how hard would it be to add piston oil squirters to our cars? as this would take a significant amount of heat out of the pistons. (i know that 3.0 and 3.5 non turbo nissans can be upgraded, however the turbo cars came with them, so that may be why)... i dont know what about those two cylinders running lean as the are closer to the throttle body? (just talking out my ass, to see what can be dreamed up). also what was the mixture like (12:1, 13:1)?
