Boost Is Better

ProCharger’s bolt-on supercharger reveals the true potential of Ford’s 7.3L Super Duty big-block.

Nov 17, 2020
Ford created quite a buzz of excitement in late 2019, when it revealed that an all-new 7.3L V-8 gas engine would be the standard powerplant for its 2020 Super Duty lineup. As traditional pushrod engines go, big cubic inches (445 for the 7.3L) and the torque they create are highly desirable in vehicles like pickups that are used for towing and hauling.
Built in Ford's legendary Windsor engine plant in Canada and code-named "Godzilla," the new mill, which, at 445 cubic inches, officially classifies as a "big-block," makes 430 hp and 475 lb-ft of torque, stock performance that is light-years beyond the V-8 and V-10 gas and diesel engines of the Blue Oval's 1998-2019 fullsize rigs.

With the 7.3L gasser, Ford's F-250s and F-350s are now in an entirely new space with regard to towing ability and simply accelerating in general (we recently learned the same capability boost may come to the F-150, as well, as the Windsor engine ops might have a 6.8L/415ci V-8 powerplant in the works for the half-ton rig by 2022).

During our 2020 Pickup Truck of the Year evaluation, the torquey engine made quick work of helping an F-250 Tremor carry a 2,600-pound payload and also tow a 10,000-pound trailer up and down an aggressive grade in Southern California. And from an overall speed perspective, Godzilla motivated the same truck to go from 0 to 60 mph in 8.5 short seconds.

When a truck and/or its powertrain (a ten-speed automatic transmission supports the 7.3L engine) are already heralded as being very good, many times owners want more than just good. The next desire is "better," and thus begins the quest for finding ways to improve their rigs' stock performance. Accessible Technologies Inc., maker of the widely popular ProCharger brand of centrifugal superchargers, knows this and for many years has produced bolt-in supercharger systems that greatly increase the power and torque of engines in cars, trucks, boats, motorcycles, etc.
Given ProCharger's successful history with improving big-block performance, typically in cars and boats, the idea of mating a blower with the new 7.3L in Super Duty is a no-brainer. And as such, the company has created a version of its belt-driven High Output Intercooler Supercharger System specifically for 2020-present F-250 and F-350.
The new system is anchored by ProCharger's venerable P-1SC-1 head unit that's supported by a three-core air-to-air intercooler. At full song and with 93-octane pump gas, the setup is capable of making 8 psi of boost, which dyno results show can produce nearly 50 percent more horsepower than the stock engine.

And thanks to the system's HP Tuners ECM calibration, Super Duty's ten-speed automatic transmission compliments the blower, maintaining boost throughout the powerband with, and especially without a load. It's good enough to drop a single-rear-wheel crew-cab's 0-to-60 time to 5.5 seconds.
We think having boost and power on demand—via a simple smash of the throttle pedal—is a sure way to make Ford's heavy-duty rig much better. Fun to drive, with the acceleration of a sports car, and greatly improved torque that can help bring towing capability on par with 6.7L diesel-powered trucks, for a lot less money.

Bolt-On Installation

Despite Godzilla's newness, truck systems are old hat for ProCharger. The high-output setup for 2020-present Ford Super Duty bolts on using only a modest collection of mechanic's tools and without modifying the engine or truck (including the radiator core support) to complete an installation. ProCharger engineers designed the system so the blower and intercooler are in optimized locations that will minimize heat transfer to either component.

The $7,198 package includes the aforementioned P-1SC-1 supercharger and intercooler, as well as all of the cast-aluminum and billet brackets, hoses, clamps, crank and idler pulleys, DeatschWerks 50 lb/hr fuel injectors, lower-heat-range spark plugs, a six-rib drive belt and the all-important HP Tuners ECM calibration. The stock fuel pump is retained and does not require any boost devices to support the blower, and the truck's original airbox and filter are also used with this system.

On the Dyno

With the ProCharger High Output Intercooled Supercharger System installed on a 2020 Ford F-250 crew cab, dyno results (on 5 Star Tuning's Dynojet chassis dyno) show rear-wheel power climbed to 524 hp and 557 lb-ft of torque, from 380 hp/399 lb-ft in pre-blower, naturally aspirated trim.

That's wickedly impressive performance from the system's basic ECM calibration and 93-octane pump gas. Of course, a glory pull was also made. With 5 Star's custom HP Tuners calibration loaded in the ECM, performance improved to 545 hp and 572 lb-ft of torque (with peaks of 583 hp/594 lb-ft).

For enthusiasts interested in pushing the boost envelope further than 8 psi, using smaller blower pulleys, bigger fuel injectors, pumps, lines, high-octane racing fuel, and custom ECM calibration, a "Tuner" version of ProCharger's HO Intercooled Supercharger System is also offered for $5,998.
