Just looked at the Edelbrock catalog, and it says "designed, cast and manufactured by Edelbrock", so it's only the main supercharger component itself that is shared with the Magnuson. General torque curve and gains should be very similar to the Magnuson, so now it's competition for price, fine-tuning (driveability), and customer support.
