to reach a flatter boost curve like a PD supercharger or a turbo it would require such a small pulley that you ll overspin and break the impeller
Centrifugal sc anyway won't put out much boost at lower rpm even with a smaller pulley because it just won't spin enough
EDIT: and then after writing I remember that you actually don't have a centrifugal supercharger but the Harrop, sorry

It would be easier to choke the inlet, but that wouldn't really be the same as doing boost-by-rpm, boost-by-gear, multiple boost maps, etc, nor would it solve the inefficiency of over-spinning the blower, but it would create the effect of flattening the top end of the power band, so the car has a broader torque curve.
