I put a thicker washer in my by-pass to up the pressure
due to a error in my build(forgot the plug in the front
oil galley) and when I figured out what the problem
was and corrected that , I forgot to pull that washer
out and when I rev'd it the pressure went to 140 and
blew the oil filter apart.... so watch out for that high
pressure...... also it takes more HP away from your
engine to spin the pump with all that pressure
This was on a BB
