I also have a Lysholm supercharger IHI brand of 1000cc capacity, twin-screw design with Teflon coatings 40cm long, 17.5cm wide and 15cm tall. Each rotor rotates at different speed. Induction air is compressed as it travels along the length of the rotors, giving less charge-air temperature increase than a similar Roots design. These are probably the most desirable of all blower types.

According to contact between enthusiasts and Lysholm engineers, the unit on the millennia is closest in specification to the Lysholm 1200AX which moves 1.2 liters of air per revolution and has a maximum operating pressure ratio of 2.2 or 17.5psi and a peak flow of 635 CFM or in other words 423 horsepower @ 17.5psi!

The main difference between the Lysholm 1200AX and the Lysholm/IHI on the Mazda is the design and compactness of the new housing, the design of the housing inlet on the Mazda looks like a significant restriction point (especially since the air passing through it is not yet compressed) and there is potentially a significant power gain to be found.

Includes throttle body.

At 14 psi good for 160+kW from a 2.25 liter engine
$270 inc. postage australia wide

Edit:
Also have round pot manifold with a few cracks from overtightening
but can easily be fixed and 32/36 weber for sale.
