I love every word of this discussion - it is very helpful and I appreciate the help.
As for the higher performance = higher oil temp, which could contribute to HPFP failure; I guess this may be true and I am no engineer, but if that is what caused my HPFP failure, why is it that many N54 powered cars don't even come with an oil cooler from the factory to this day, including e89s. That would almost guarantee failure.
