Baseline '03 Cobra-Eaton M112 (11 psi)
What's not to love about the supercharged '03 Cobra 4.6, especially when the boost is cranked up to 11.7 psi (thanks to an 8.5-inch crank pulley)? Equipped with the Accufab throttle body and inlet, XE264AH Comp Cams cam and Flowtech long-tube headers, the Eaton-supercharged 4.6 produced 572 hp and 533 lb-ft of torque. While the 533 lb-ft of torque is an impressive number, it is nowhere near as important as the fact that the torque curve exceeded 500 lb-ft from 3,100 rpm to 5,800 rpm. Even down at 2,500 rpm, the blown Cobra motor pumped out 480 lb-ft.
