Today's late-model Ford F-150 5.4L truck engine offers a factory fuel injection, three valves per cylinder-two intake, one exhaust-a computer-controlled cam and ignition timing. Also, it is rated at 300 hp and 365 lb-ft of torque. After scanning the market for bolt-on horsepower, we bolted on a supercharger that would deliver the most gains for the buck.
The intercooled ProCharger system delivers large improvements in performance and power for increased towing and all-out horsepower production. Recently, we installed a ProCharger centrifugal supercharger with intercooler on an '05 Ford F-150 5.4L V-8 engine and made gobs of tire-smoking power.
The Procharger Intercooled System Will Allow Power Gains Because1. Cooler air is denser, so its molecule structure is smaller and more compressed.
2. Cooler air temperature reduces total spark advance closer to create ideal peak power and boost production.
3. The use of an intercooler produces higher peak-boost levels for pump gas, which means that cooler air densities double that of atmospheric may be used on some pump-gas applications, resulting in power output nearly double what is obtained when operating naturally aspirated.
