When I start mine, it goes to 85-90 , when hot about 20 idleing. Raise the rpm, the pressure goes up accordingly. My main and rod clearance is .002-.0025, running 20 w 50 "5qts"dyno and 2qts syn. mixed. As I CHANGE FILTERS OFTEN BECAUSE OF HAVING TO RUN THE SHORT ONES, I REPLACE W/ THE SYN. FU------ FAT FINGURES !
