Magnuson Products, Inc. manufactures a two piece drive assembly for Eaton Superchargers. When combined with the more limited flexibility of the one piece drive and the available adjustment  in pulley offset, this assembly gives the fabricator the ability to extend or pull back the centerline of the pulley to almost any position.

Magnuson Products, Inc. maintains an inventory of Standard Extension Drives for both 3rd, 4th, & 5th Generation superchargers.  For any specific installation questions, call our technical staff.  The variation shown is achieved with variable pulley offset (see R&D pulleys).

MP90 3rd Generation w/2-Piece Drive

NOTE:  The dimensions on the gear cover and extension drive (the components that make up the "Range") will apply to the M45 & M62 3rd generation also.  The only dimension that will vary applies to the rotor housing section.  For ordering purposes the important dimension required by Magnuson Products is the "Range" to the centerline of the pulley.

4th & 5th Generation w/2-Piece Drive

The Extension Drives for 4th & 5th Generation superchargers are the same as for 3rd generation superchargers with the exception of the gear cover assembly, which gives the overall assembly a different range.  For any specific installation questions, call our technical staff.  The variation shown is achieved with variable pulley offset (see R&D pulleys).
