Cougar XR7 3.8L Supercharged V6

3.8L Supercharged V6 In 1989 and for the first time in Cougar history, no V8 engine would be offered. The lower cowl of the new MN-12 chassis did not allow the traditional 5.0L to clear the hood; engineers would continue to work on getting the 5.0L to fit without a power decrease and finally get it into the cars for 1991. In the meantime, the base engine was the naturally-aspirated 140 HP 3.8L V6. The XR7 and the Thunderbird Super Coupe would receive the all-new supercharged 3.8L V6. By incorporating the Eaton M90 the motor put out a respectable 210 horsepower and over 300 lbs of torque. Optional on the XR7 was a Mazda-derived M5R2 5-speed manual transmission. The "truck" transmission was chosen because it could manage the supercharged motor's torque production. Eaton had been urging Ford to incorporate the modified Roots-type positive displacement pump since 1977. The 1989 and 1990 Cougar XR7 was winner when Ford finally decided to use it on the 3.8L V6.
