The Ford F250 Power Stroke 7.3L Mega Site

The legendary 7.3 L Power Stroke turbo-Diesel V8, 250 hp/500 ft.lbf (Super Duty) was manufactured between 1999-2003. It fell within the tenth generation of the mighty Ford F-Series of trucks which ruled the world of trucks from 1997-2003.

With the arrival of the Super Duty a wide variety of body options were available: regular cab and SuperCab, standard or flareside boxes, and short and long beds. A new Lightning was introduced in 1999, and Harley-Davidson and King Ranch versions were also created. In 2001 the SuperCrew cab was introduced. The super-duty F-250 and F-350 were retained on the old chassis until 1999.

The 7.3L Power Stroke, when introduced, provided more horsepower and torque than its competition. It provided 20 more horsepower than the 7.3L IDI Turbo it replaced, 20 more than its GM competition, and 25 more than the Dodge 175hp Cummins. The torque figures were also impressive, with the latest unit delivering 100 lb-ft more than the IDI Turbo, 40 more than GM, and 5 more than the Dodge/Cummins.

Broken down, the new DIT version included a displacement of 7.3 liters or 444 cubic inches. The V-configured eight-cylinder mill had a bore and stroke of 4.11x4.18 inches. Its compression ratio was 17.5:1, directly supplied with eight single-unit injectors, mounted one per cylinder. The mill was electronically controlled with Ford's new and exclusive EEC V engine control system. The cold-start system used glowplugs, and the unit (as earlier mentioned) was turbocharged. The new mill delivered 210 hp at 3,000 rpm, with peak torque delivery of 425 lb-ft of torque at 2,000 rpm.

The 7.3L Power Stroke is arguably one of the best diesel engines ever made.
