Lysholm Twin-Screw supercharger systems are available from Vortech authorized dealers. The products meet the standards set by OEMs and aftermarket suppliers. The Twin Screw Supercharger was invented by Mr. The twin screw design was developed to replace dynamic type centrifugal and axial turbine compressors, for boosted engines.
This development led to a supercharger which was compact and lightweight with increased efficiency for operating conditions of pressure and speed.
The Lysholm supercharger of today features several patented aspects, including rotor profiles and bearing arrangements. Multiple OE customers have successfully completed extensive and brutal evaluations of the Lysholm unit prior to their incorporation into their products.
The OE process included a durability study where the compressor successfully completed test cell hours at full throttle plus additional tests that proved the increased power and torque would not sacrifice fuel consumption or emissions levels.
As with Vortech products, Lysholm tests all supercharger products resulting in accurate performance maps. Over the years, OE development engineers have found these maps essential to matching and optimizing supercharger — engine combinations, and obtaining absolute best performance, economy, and durability from their powertrains.
Further, cell testing has proven crucial in the product development cycle, as validated by the numerous, patented features and improvements already mentioned. Lysholm quality assurance, assembly techniques and testing have translated well on US highways as documented with a recent application in which a Lysholm Model compressor logged more than , miles on a GMC Yukon. The owner was so impressed with the durability and performance of the unit that, when the original engine was replaced, the supercharger was reinstalled and still delivers the boost.
Beware of imitations. Lysholm is the source of the twin-screw, positive displacement compressor technology for automotive and marine applications. Superchargers will always be the best alternative for performance enhancement, not only for the more exclusive vehicles but also for mass produced engines in automotive and marine applications. Genuine Lysholm Technology Multiple OE customers have successfully completed extensive and brutal evaluations of the Lysholm unit prior to their incorporation into their products.

The present invention relates to compressors of the rotary screw type in which two or more cooperating rotors mounted within a suitable casing operate to provide compression spaces, the volume of which varies upon rotation of the rotors to effect compression of the working fluid within the compressor. In compressors of this type, compression spaces on each of two cooperating rotors are brought into communication with each other and thereafter the two spaces work together as a common compression space until further rotation of the rotors brings one or the other or both of these spaces into communication with an outlet port in the casing. We have discovered that the action of the rotors in previously proposed forms of screw type compressors is such that reduction in volume of any given compression space in one rotor commences prior to reduction in volume of the compressor space in the cooperating rotor with which the first space is brought into communication. The result of this is that two compression spaces are brought into communication with a certain amount of compression having already taken place in one, whereas it has not taken place in the other. Consequently, when communication between the two spaces occurs, equalization of pressure between the two spaces takes place and the pressure of the working fluid which has already been partially compressed is reduced. This reduction in the pressure of the working medium which has already been partially compressed results in an increase in entropy with a corresponding loss of work.
A rotary-screw compressor is a type of gas compressor , such as an air compressor , that uses a rotary-type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high-pressure air are needed, either for large industrial applications or to operate high-power air tools such as jackhammers and impact wrenches. For smaller rotor sizes the inherent leakage in the rotors becomes much more significant, leading to this type of mechanism being unsuitable for small air compressors. The gas compression process of a rotary screw is a continuous sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors.
