Basically, my understanding is that the filter would keep any thrash from a blown engine from entering the cooler - which as many have pointed out is almost impossible to get clean of all possible debris. I am not certain why this apparently can not be counted on to stop the trash, but I will certainly defer to Lynn and those with a lot more experience in trashing engines than I have.
So its understandably that the racing crowd pushing engines into the very high power and rpm range stand a higher probability of trashing an engine than in aircraft application.
In any case, have not trashed an engine to the point of finding metal in the oil (yet).

I am happy that this has worked out for you. Why did you decide to run the filter before the cooler?

I have my oil filter before the oil goes into the cooler and has worked fine
for 400 hours.
