We already know that the casting alloys used by Porsche for the M96 are suspect and do suffer from cracking and failures. A simple 15-25F degree reduction in temperature can translate into an increase of several thousand psi of the tensile strength of an aluminum alloy. There are areas of the engine much hotter than what the temperature gauge indicates. Depending on the alloy, you can lose an additional 30 to 50% tensile strength from 212F to 300F.
