KB SC '03 Cobra-20 PSIGiven its humble beginnings of something near 360 rwhp, it's amazing to see this Terminator motor thumping out nearly twice that power level all from a simple blower upgrade. Terminator owners should give thanks for Ford's decision to go the forced-induction route rather than increasing displacement. Running 20 psi of boost, the Kenne Bell supercharged 4.6L Cobra motor thumped out 702 rwhp and 578 lb-ft of torque. In true positive-displacement form, torque production from the supercharged motor exceeded 500 lb-ft from as low as 2,400 rpm all the way to our self-imposed rev limit of 6,700 rpm. The power curve was still headed up at 6,700 rpm, so we know there was more power to be had from this combination.
