View Full Version : Why do the 1994 and 1995 Super Coupes have more power?

The biggest change to the 94-95 SCís was that it received the upgraded 3rd
generation Eaton M90 supercharger with epoxy coated rotors. The coating
made the rotors more thermally stable, therefore, Eaton could reduce the
clearances between the rotors and the case for reduced pumping losses. These
superchargers are much more efficient than the older ones, thus allowing it to
realize higher power outputs. They are so efficient that Ford actually used a
larger pulley compared to the í89 to í93 model year superchargers. Despite the
larger pulley, they still flow more air than the early model superchargers. Some
other changes to the motor include higher flowing 36lb/hour injectors, different
cam profile and the debut of the electronically controlled automatic transmission
(4R70W). The were a host of other changes for the 94-95 3.8L that are listed
in much more detail here (link to the article)
