by fitting the newer smalll type of oil filter, i improved it back upto around 79-80PSI peak oil pressure.
filter with less "total filtrate area" would result in less head loss (aka pressure loss, cause some pressure is used to push the oil tru the filter), assuming the smaller filter has less filtrate area. well, that is my understanding from the fluid mechanics class þ..
