I've seen many tech articles referring to gear ratio for superchargers when trying to explain/calculate amount of boost produced. How is this calculated? Ratio of crank (drive) pulley size to size of blower pulley??? When I do mine 2.95 upper to 7.0 lower it comes out to 1:4.2 which seems high...when most articles refer to ratios in the 1:3.5 range or less.
