Whipple's are twin-screw superchargers. Inhearantly more efficient that the 5th Gen Eaton roots-type superchargers used in OEM and many aftermarket kits. The roots-type respond a little better in the lower rpm ranges, the screw-types maintain efficiency at higher pressure ratios. Magna also carries the 6th Gen Eaton TVS superchargers. Vastly improved over the older 5th gens and are at least as, if not more, capable than Whipple/Kenne Bell superchargers.
