Thought's on running vacuum pumps at the standing mile (or any land racing). How many run one and at what inHg do you run them at? I ask because of the length of time at a high RPM the draw of internal lubrication. I run 9-12 inHg in the 1/4 but for a tick over 9 seconds. My thought at a extended run you would want to drop the inHg to 2-8. You get the Horsepower gain but not the hard draw. Even a evac system off the header collectors would do some good.
