2003 Mercury Marauder - Four-Door Flyer

Steve Schingler's sneaky '03 Mercury Marauder

Who: Steve Schingler

What: '03 Mercury Marauder

Where: Braselton, GA

Engine: Proline Racing Engines assembled the 4.6L mod motor with an '03 Cobra crankshaft, Carrillo billet connecting rods, and 0.020-over Diamond pistons. The cylinder heads are stock castings, ported by Chris Howe, fit with larger valves and four custom-grind camshafts.

The intake is port-matched and the headers are from Kooks with 3-inch exhaust pipes and MagnaFlow mufflers. Injected Engineering handled much of the final assembly of the engine and tuned it using SCT software. On Injected's Dynojet chassis dyno, the car made 677 hp and 572 lb-ft of torque on 93-octane pump gas. When they swapped to C16 race gas and cranked the boost to 26 pounds, the Marauder pumped out 829 hp and 663 lb-ft of torque. Pretty good for 284 ci.

Power-adder: Injected Engineering outfitted the mod motor with a Vortech Ysi centrifugal supercharger, which features a custom air-to-air intercooler mounted behind the front bumper. The fuel system is upgraded with twin Ford GT pumps and a set of 80-pound Ford Racing injectors, while the ignition system is bone stock.

Transmission: Lentech built the 4R70W automatic overdrive transmission with bulletproof internals. Power application is handled by a Precision Industries torque converter, which stalls to 2,800 rpm on the line. A Dyno Tech aluminum driveshaft connects the transmission to the 8.8 rearend, which has a 4.10 gearset, a pair of Mark Williams 35-spline axles, and a spool.

Chassis: The full frame Marauder still relies on its stock rear suspension setup, which has air springs in the rear. Strange shocks ride on all four corners, and Metco upper and lower rear control arms help plant the tires. The front suspension has been converted to coilovers, and Steve added Baer brakes to the front, too. He sent the car to Bell Chassisworks to have the eight-point chrome-moly rollcage installed.

Wheels/Tires: The Mercury rolls on a set of stock-appearing wheels. The fronts have been narrowed to 4 inches to greatly reduce weight and rolling resistance. When he visits the track, he swaps the stock rear wheels for a pair of bead-locked Holeshot 16x10-inch wheels wrapped in Mickey Thompson 295/50R16 Drag Radials.
