Once the belt tensioner and idler pulley are secured on the head unit’s mounting plate, Ricardo bolts the stout (1⁄2-inch-thick) plate to the front of the engine.
With the supercharger independently turned by the crankshaft, the factory six-rib serpentine belt is still employed for driving the ‘Stang’s accessories. To facilitate the blower installation without compromising idler pulleys for the serpentine setup, a longer bolt that passes through both the mounting bracket and the pulley is included in the kit.
With the mounting bracket in place, Ricardo bolts-on the ProCharger P-1SC-1 head unit.
The eight-rib supercharger belt is the final piece of the supercharger’s drive system.
Ricardo installs the three-core race intercooler, which is supported by a bracket that bolts to the Mustang’s core support and the bosses that are welded on top of the ‘cooler.
For its Three-Valve (and now Coyote) systems, ProCharger now incorporates the mass-air sensor directly into the intercooler, right at the discharge. A DiabloSport MAFia unit is included and serves as a wiring extension that links the sensor to the OEM harness.
The passage of supercharged air from head-unit-to-engine is handled by a series of 2.5- and 3-inch discharge tubes. While finagling and adjusting is necessary, the supplied piping, elbows and couplers are designed to fit cleanly within an S197’s engine compartment without requiring any cutting or other modifying of the ’Stang’s chassis.

The HO system’s ProFlo bypass valve is positioned in the tube that is just in front of the intercooler. The valve basically vents bypassed air (pressurized air that otherwise has nowhere to go when the throttle is closed) directly into the atmosphere, and features a small filter on the end that’s used to knock down some of the noise generated by the bypassed air.
For ’07-’10 Mustangs, this EVAP component must be unclipped from the strut tower and moved down a few inches to create sufficient clearance from the blower’s rear-mounted air-inlet tube/filter assembly. With this piece in place, there’s absolutely no way the tube can be properly installed.
As a self-contained supercharger, the P-1SC-1’s internals do not require any lubrication other than the 6 ounces of proprietary oil that is added before the project is completed. 5.0


On the Dyno

From its rather demure initial showing (by today's Internet-fueled standards) on the Dynojet chassis dyno at GTR High Performance (baseline peak power and torque was approximately 269/290 at the feet), Eric Bell's bone-stock '07 Mustang GT definitely earned street-hitter status with the ProCharger P-1SC-1 supercharger (PN 1FP214-SCI; $5,896) and the included ProCharger-prepared PCM calibration, which was uploaded into the PCM via DiabloSport's i-1000 InTune unit.

To give you an idea of this upgrade's effectiveness, consider the project featured in "Back to Cool," a report on Three-Valve mods in our Dec. '13 issue. In that article, we detail how Candy Barrientos' '06 Mustang GT produced 270 horsepower in its stock state, which is strikingly similar to the amount of peak steam that Eric's Steed produced. After adding naturally aspirated bolt-on pieces from Granatelli Motorsports, rear-wheel performance rose to more than 300 horses on Candy's ride.
