The supercharger should be matched to the engine size, roughly speaking a 4 cylinder engine of 2ltrs would injest 1 ltr of air per revolution, you would want a supercharger that displaces something like that per revolution, you can then adjust boost pressure by drive ratio, the faster you drive the charger in relation to the crank the higher the boost.Hopefully if you gear it right the pressure will be linear,
in other words the same throughout the rev range.
