My OperaMagnuson Supercharger

A Supercharger is a positive displacement pump. Its purpose is to increase air pressure and density in the intake manifold. It does this by pumping more air than the engine would use without a supercharger. The supercharger is matched to the engine by its displacement and belt ratio, and can provide excess airflow at any engine speed. This concentrated charge of air provided by the supercharger results in a more powerful combustion stroke in the engine's cylinders, resulting in improved performance over non-supercharged vehicles.
Supercharging is compatible with all types of fuels including flexible fuels, i.e. CNG (compressed natural gas), propane, etc. Fuel economy is not compromised, as described above in item 7, when utilizing the bypass system in conjunction with the supercharger. EPA (environmental protection agency) figures support this claim. A typical domestic vehicle equipped with a Magnuson supercharger shows no fuel economy penalty for highway driving, and only a one mile per gallon penalty for city driving.
The Magnuson super charger is essentially a Roots blower pump, with one substantial design wrinkle; each rotor has been twisted 60 degrees to form a helix. The two counter rotating rotors have three lobes, which intermesh during operation. These twisted rotors, along with specially designed inlet and outlet port geometry, help to reduce pressure variations resulting in a smooth discharge of air and a low level of noise during operation. This arrangement also improves efficiency over traditional Roots superchargers. With helical rotors and an axial inlet the Magnuson supercharger can be spun to up to 14,000 rpm, thereby reducing package size.
With the continued interest in performance, and the desire to maintain fuel economy, supercharging could be the ideal product of the future. Using a Magnuson supercharger to increase power on a smaller displacement engine, in turn achieving the performance of a larger engine, but not compromising fuel economy seems too good to be true--but that is what a Magnuson supercharger provides.
