Superchagers
The underdrive on super chargers. Does a lower % give more or less boost then a higher % ???

Higher underdrive number=less boost.
Remember, the percentage is the underdrive...or the number of blower turns versus crank turns.
75% underdrive...4 crank turns, 3 blower turns
50% underdrive...4 crank turns, 2 blower turns
The slower the blower, the looser the boost!!!Ensure that the path of least resistance is not you...
