SN-95 2 Supercharged SVT Cobra

2003-2004

Debuting in early 2002, the 2003 Cobra came with a supercharged 4.6 L DOHC engine rated at 390 hp @6000rpm and 390 ft·lbf of torque@ 3500rpm. It was later determined that Ford had under rated the Cobra, as actual SAE-corrected flywheel output was determined to be in the 390 to 400 horsepower (300 kW) range. Numerous improvements were made to the powertrain and driveline to handle the increase from the previous model year. A cast iron block was used instead of aluminum, with stronger internals including forged Zolner pistons and Manley H-beam connecting rods that were modified with a wrist pin oiling hole by the SVT engine builders. These upgrades were critical in order to support the 8 psi (60 kPa) of boost delivered from the stock Eaton M112 roots supercharger. Other improvements include the use of an aluminium flywheel connected to a Tremec T-56 six-speed transmission, 3.55:1 rear axle ratio and stronger 31 spline half shafts with revised upper and lower control arms.

For 2003, SVT offered a limited-edition Tenth Anniversary Cobra which featured unique color paint scheme]]. The
