2003 Ford Mustang Mach 1

We've done several features on '03-'04 Mach 1s, and we're fairly sure all of them have retained mostly stock interiors. We guess it's because the Mach 1 interior was a major reason why the car was bought in the first place. As for Tim's Mach 1, he added the essentials such as an AEM boost gauge, and AEM air/fuel meter, and a Raptor shift light. Connected to the ProMotion Powertrain-modified Tremec TKO 600 is a Pro-5.0 shifter.

Modular Madness [(941) 527-0156; www.modularmadness.com] in Bradenton, Florida, put together a solid power foundation by using an '03 Cobra iron block, a Cobra crank, Manley rods, and Mahle pistons. This combination dropped the compression ratio to 8.5:1, which is much more boost-friendly when compared to a stock Mach 1. The heads-well, they're Mach 1 Four-Valve heads, so they were simply treated to a valve job and high-rpm-capable valvetrain components. After going through a Vortech SQ S-Trim and a ProCharger F1-A supercharger, Tim settled in with a Hellion Power Systems single-turbo kit with a Turbonetics T76 unit. To make the most of the turbo kit, Modular Madness added Crower custom grind camshafts with the corresponding valvesprings to enable the combination to easily rev past 7,000 rpm. A pair of Ford GT fuel pumps feed the hungry Four-Valve, thanks to Performance Fuel Systems' high-impedence 83-lb/hr injectors. All told, the combo is good for 732 hp and 695 lb-ft of torque to the tires on 116-octane race gas. Modular Madness' Don Walker says the Mach will be tuned for 93-octane gas to around 650 hp, but more is in store to bring the horsepower numbers up to the 800-850 mark.
