[QUOTE="ELP_JC, post: 281542, member: 6177"] That makes perfect sense. A big metal rod is much heavier than mercury, just as mercury is much heavier than ATF fluid. Also worth mentioning is mercury stabilizes at higher rpms, where vacuum is less. And the restrictors provided by MotionPro are only the size of a small pin, but still allow some bouncing at idle (highest vacuum pulsations). So will measure the middle of the range then. Thanks man. JC [/QUOTE]
