One would be more than enough for an airplane at 6 or 7 thousand RPM. Most cans have a bypass delta. So if the element gets lots of dirt in it or the flow gets too high the element is pushed down away from the cover and oil can still get through the filter head. When this happens, the oil is not only not being filtered, it is now gathering up the debris already removed from the oil and passing it along in the outgoing oil. Or if the problem is element collapse, then pieces of element paper are sent down stream to the bearings. If that filter is just a bug screen, then no problem. If it has a paper filter element, cut it open and be sure it has more than 125 sq. inches of media. If that can has no bypass feature, element collapse just shuts off the oil supply. The stock can is small and light weight, but, it is in a street car with a low duty cycle. You should have cut open the can after the first hour anyway, looking for scrap metal and bits of sealant.
