		<description><![CDATA[Tweet The Lysholm / Autorotor Supercharger is a unique and very practical chager. The unit is a great compromize between a positive displacement supercharger (that creates boost pressure by over pumping and over feeding the engine with air) and a compressor (similar to a turbocharger) that compresses the air inside the supercharger housing before sending it out to the charger piping. The unique three-five design of the twin screw chargers relies on a 3 lobe and a 5 lobe rotor intermeshed to capture the air flowing into the supercharger for inter-screw compression. The combination of an intermeshed 3 lobe and 5 lobe rotor means that the rotors inside the housing are operating at different rpms with a ratio of 5:3 to keep the rotation of the lobes (3 lobes to 5) in synchronsim. This complex design allows the rotors to capture air (in its natural volume) from the back of the blower housing, and push it foward as the screws rotate. As the air is moved forward it is captured and compressed between the intermeshed rotors as well as being pumped (in positive displacement) from the inlet port at the back of the charger housing to the outlet port near the [...]

The unit is a great compromize between a positive displacement supercharger (that creates boost pressure by over pumping and over feeding the engine with air) and a compressor (similar to a turbocharger) that compresses the air inside the supercharger housing before sending it out to the charger piping.    The secret to this style of &#8216;hybrid&#8217; blower is the two intermeshed rotors of different lobe numbers (see illustration). The combination of an intermeshed 3 lobe and 5 lobe rotor means that the rotors inside the housing are operating at different rpms with a ratio of 5:3 to keep the rotation of the lobes (3 lobes to 5) in synchronsim. This complex design allows the rotors to capture air (in its natural volume) from the back of the blower housing, and push it foward as the screws rotate.

		<description><![CDATA[Tweet Positive displacement superchargers do not usually compress air inside the supercharger but rather better described as air pumps. Positive displacement superchargers are usually rated in liters or cubic inches (or a similar measure of displacement). The reason behind that is that a 1.5L rated positive displacement supercharger moves 1.5 liters of air per revolution and so to produce 15psi of boost (or a pressure ratio of 2.0) on a 1.5 liter engine, the supercharger would have to be geared to double the rotating speed of the engine. Thus for every round of the engine, the engine would normally ingest 1.5 liters of air, at the same time for every round of the engine, the supercharger completes two full rotations because of the gearing between the engine crank and the supercharger, and thus the supercharger puts out 3.0 liters of air for every 1 revolution of the engine. The result is that the supercharger pumping and feeding 3.0 liters of air to a 1.5 liter engine, which results in the air being compressed inside the intake manifold between the cylinder and the supercharger, and effectively forcing the engine to breathe twice as much air, simulating a motor that is twice [...]
